There is Light at the End of the Coronavirus Tunnel and it’s From a UV Light!

There are many misunderstandings about UV light that are currently being circulated around the media empires, just like all of the misinformation about covid 19 which I previously wrote about in my last article. I will try to clarify in understandable language what the misunderstanding is about. The problem is that many people no longer believe in science and refuse to try to understand it. The understanding of UV light is a matter of life and death, so everyone should try to understand the science behind it, so here I go:

  • What is UV Light? If you already know this, you can skip this section, but maybe I will have some new information for you. All energy has a frequency. Light is a form of energy. Visible light has a spectrum of colors that all have a frequency. UV light also has a spectrum but this light it is not visible to our eyes, (scientists think some animals can see this light though). There are various terms of measurements for all types of energy. I will only explain the terms for light energy.
    • Wavelength: This is simple to understand. All light energy is measured by how long the wave of light is and is measured in meters. Ocean waves are measured this way, called a swell. Light waves are much shorter than a meter and thus are measured in nanometers, abbreviated to Nm. One Nm is one billionth of a meter!
    • Frequency: This is how fast the waves transmit in time. Like the stations on your radio, they all have a frequency. This is measured in Hertz. The wavelength and frequency determine what kind of energy it is, and is measured in seconds of time, but is extremely fast, so it is measured in trillionths of a second, or terahertz, abbreviated to THz.
    • Electromagnetic Radiation: This is what light is. It is a band of electromagnetic radiation, or EM, that is part of a wide range of radiation measured by wavelength and frequency. Here is a chart that displays the types of radiation and how they are divided:
  • The Types of Ultraviolet Radiation: There are three main types of UV radiation; A, B, and C. They are called ultraviolet because they are at the violet end of the visible light spectrum as shown above. The other end of the visible light spectrum is red and called infrared radiation. UV A and B reach the earth and are responsible for sunburns, if overexposed, and getting a tan. UV B also reacts with the skin to create vitamin D in our bodies, which is crucial for fighting diseases like COVID 19.
  • Far UVC: What does the word far refer to? This is simple to understand if you look at the chart above and the one below. This is simply referring to the distance on the EM scale on the far end of the wave form for UVC. On the infrared end there is far infrared:
  • The Difference Between Far UVC and UVC: This is the most important part of this article. Far UVC is not dangerous to exposed flesh and full UVC is extremely dangerous to exposed flesh. Germicidal lamps using UVC  have been used to disinfect inside areas for more than 20 years. On the first chart above you will notice a number of 254 on the UVC scale. This is the wavelength, 254Nm that is used in these lamps. There are strict regulations on their use because even a brief exposure can cause skin and eye damage and cancer. Timers, remote controls, and motion sensors, are used to prevent anyone from being in the room when these lights are used. These lamps are used in many places where it is crucial for disinfection like operating rooms.  In 2018 some researchers experimented with different wavelengths of UVC light to see if they would still have disinfectant properties and be less harmful to exposure. They found that the wavelength of 222Nm of UVC light killed all infectious viruses, bacteria’s, and molds at the same rate as the full UVC lights. At this wavelength, the radiation did not penetrate the outer layers of the skin and eyes as does the full UVC light.

Warning: Please do not confuse the two types of lamps. If you buy a UVC lamp  that is not a far UVC lamp, do not use it at any length of time in the presents of people. Check the specifications since there is and will be companies that claim that their lamps are far UVC, and really are not. Even a low level UVC lamp can cause serious health problems.

  • Testing and Availability of Far UVC Germicidal Lights: The covid 19 pandemic started research into how this deadly virus could be stopped and is still ongoing. Early in 2020 it was announced that far UVC lamps were being tested at Columbia University for the safety to human exposure. They found that far UVC lamps showed no damage to exposure from the lamps. The lights were then given the OK to be sold commercially. They are now being used for disinfection by airlines and retirement homes. Here is an article about their use:

This is a device like the metal detectors at airports. You just stand there for a short time and it disinfects.

There are new devices being developed as I write and one of the most promising and affordable is being developed by a Michigan company. It is a chip that emits far UVC light. This is exciting because chips can easily be mass produced at a low cost. Here is an article with more information on this advance:

Recent Update: these devices are now being sold and available for pre ordering:

  • What are the Advantages of Using these Far UVC Lamps?  I think this is obvious, but it still seems to be flying under the radar of politicians and the news media. These lamps are safe to use everywhere. They kill all dangerous pathogens, not just covid 19, but all viruses, bacteria, and molds. They can be installed like a regular lamp and kill the bugs constantly in all spaces without any politics or effort of the people using the space. The light can even disinfect if the beam is reflected off of surfaces, so it then can reach under tables and in the areas not in a direct line of the beam. The most important advantage is that disinfects the air! If an infected person breaths out, the light kills the virus that is in the air as it comes out of their mouth and nose.
  • Why is this Technology Flying Under the Radar? I can only come up with one reason, and recently I have seen proof of my theory. What happens if these lamps are used in all public places? Diseases that are spread in the air and surfaces will no longer be passed between people! Does that sound like a good thing? To most people it would be a resounding “Yes”! No more sickness and death from communicable diseases like colds, flu, pneumonia, or antibiotic resistant bacteria. Billions would be saved in hospital costs and lives lost. That should give us a clue to what is going on. Who would lose if far UVC lights were in all public places? I think you can figure this out; pharmaceutical companies that sell all of the medicines for the treatment of these diseases! There have been recent reports about the dangers of germicidal lights stating that people are being harmed by them. Here is one of them:

https://www.nbcnews.com/health/health-news/doctors-warn-about-eye-damage-uv-lights-kill-coronavirus-n1249009

Why would NBC news and other news outlets report this? If you have watched these news channels, you will notice that almost every commercial break is flooded with pharmaceutical adds. Tell me there is no connection! Expect that this will continue in the future, but I am confident that science will win in the end. The world will be a much better place if far UVC lamps are used, and transmission of current diseases, and future outbreaks of potential Pandemic viruses, are stopped and eliminated.

The Top 10 Ways to End the COVID 19 Pandemic

Posted on Updated on

This is my list of the ways that the COVID 19 pandemic can be stopped and brought under control. It is in order from what I believe is the least effective to the most effective ways to combat COVID 19. I will try not to involve any politics in this list but it may be necessary to mention how the results are effected by politics. This pandemic should not be in the least bit political, and should be purely scientific, but that has not been the case. I think some of the answers may shock you, or just surprise you, since some are not widely known or understood.

1.

Herd Immunity: This concept is widely misunderstood but is actually simple. That is why I have two spots on my list. Both classifications have the same result: A certain percentage of the total population becoming immune to the virus will stop the spread of the virus. That number is estimated between 50% and 95% of the population. The percentage is determined by how infectious the disease is, or how easily it is spread from person to person.

What is debated is how to achieve this percentage. The doctor in charge of the Trump task force says that herd immunity should be achieved by just letting the disease run its course through the population. The other method is by increasing the immunity with vaccinations.

First, the problems with letting the disease run its course. They are stating this, but also saying that while most of the population who survives the disease by not dying will have immunity, and the population that is in the most danger of dying from the disease would need to be protected (quarantined) from getting the virus. This is an overgeneralized statement since a large percentage of the population is at high risk of becoming seriously ill from the disease, and it is nearly impossible to tell who is going to die from the disease. Many people at risk have no way to protect themselves totally (extended quarantining for many months?). Then there is the moral issue: Letting 1% of the population die to reach herd immunity! 1% seems like a small number but 1% of 300 million people is 3 million people that would perish! This number might be reduced in the future but even .5% death rate would mean 1.5 million people will die! The death rate today stands at around 1% for people contracting COVID 19, and is higher in poorer communities. Not a good idea in my opinion! Here is a link to an excellent article that explains more about herd immunity:

https://www.nature.com/articles/d41586-020-02948-4

2.

Herd Immunity by Vaccination: As mentioned before, this is getting to that magic percentage where the disease stops spreading by vaccination. This seems simple but it has major drawbacks and problems.

The worst drawback is that there is a public distrust of vaccinations. In a recent poll that asked if you would take the COVID19 vaccination voluntarily, 50% said “no”! This alone would not be enough to sto p the spread of the disease even if the vaccine is 100% effective, which leads me to the second problem. No vaccine is 100% effective. The seasonal flu vaccine is only about 50% effective. In other words 50% of the people that take the vaccine still get the flu! So if the COVID 19 vaccine is only 50% effective but is given to everyone (which will never happen), more than 150 million people will still be able to get COVID 19 and 1.5 million to 750 thousand of them could eventually die since the spread would not be stopped but would just be slower. Of course 1.5 million to 750 thousand lives would be saved which is better than solution 1 on my list!

Another problem is that no one is sure of the percentage that is needed for herd immunity. And yet another problem is that the vaccine might become ineffective if the virus mutates which many viruses do over time.

The last problem with vaccination is that it is not known how long the immunity will last with each vaccine. The only way to know this is to give the vaccine and see how many people get sick over time. It might be only one month, six months, one year, or a lifetime. There is no way to know until that time has passed!

One positive thing about a vaccine when it becomes available, is that it will reduce the infection rate among high risk people and will protect people who have a high exposure to COVID 19, like first responders, medical personal, and essential workers. Don’t get depressed, there are eight more solutions to explore.

3.

Increasing Resistance to Getting COVID 19: Most people who contract COVID 19 only have mild symptoms. 80% do not need any hospitalization. Why do the other 20% either get seriously ill or never recover? The medical community states the main reason is something called comorbidity, which basically means that they are in poor health. Medical conditions such as diabetes, cancer, obesity, congestive heart conditions, asthma and other lung diseases cause a higher percentage of patients to need hospital care after contacting COVID 19. But why is this?

There are clues and studies, some of which have led to the death rates going down. It all has to do with having a healthy immune system. Not all people with comorbidities end up in the hospital and many people without comorbidities end up in the hospital, and some die.

Why does the seasonal flu increase in the fall, and peak in the winter? Many scientists say it is because we go inside and pass the diseases between each other and colder outside temperatures. This is a vague explanation and has little scientific merit. The real reason is simple. It does have to do with people going inside, but not directly. It has to do with the seasons. In the fall the days get shorter. There is one element that is important in having a healthy immune system. It is not a vitamin but is called a vitamin. People mainly get it with sun exposure but it is also in some foods. It is a type of hormone called vitamin D!

Absorption through the skin with direct sun exposure is the main way that we get vitamin D. In the fall we go back to school and work and the days grow shorter reducing the amount that we absorb and have in our systems. Many peer reviewed studies show that being deficient in D leads to a compromised immune system. This leads to lower resistance to many diseases and conditions such as the flu, all contagious diseases, cancer, heart and lung diseases, and nervous system conditions, just to name a few.

The percentage of the population who is deficient in D varies greatly. The farther north that people live is causally related to deficiencies as one example. Skin color is another factor since darker skin does not absorb vitamin D as easily. The percentage of people in the US that are deficient is somewhere around 45%! That means that their immune systems are compromised and more susceptible to having a bad outcome with COVID 19 infection. 80% of hospitalized COVID 19 patients have vitamin D deficiencies.

One of the main treatments for hospitalized COVID 19 patients is supplementing vitamin D and other vitamin supplements that are proven to help the immune system be stronger. Zink, selenium, magnesium, vitamin A and E, and others along with D have doubled the positive outcomes of hospitalized COVID 19 patients.

In conclusion these vitamins can help in the treatment of COVID 19 and in the prevention of having to be hospitalized and dying. This is a good thing, but the problem is that the medical community does not recognize vitamin therapies widely, and no matter how much they help, they do not prevent the spread of the disease. Any other treatments being developed also do not stop the spread. Here is a link to more information on these developments:

https://www.health.harvard.edu/diseases-and-conditions/treatments-for-COVID 19

4.

Complete Shutdown: Shutting down all of the economy and confining people to stay at home can stop the spread of the virus, but it is impractical. People need to go out and buy food, go the pharmacy, and other essential travel and not everyone can work from home, and many peoples jobs are essential, like police, fire, ambulance, doctors, and nurses, and many businesses cannot close like pharmacies, and grocery stores. Early in the COVID 19 pandemic this was tried but failed to stop the spread, but did slow it down until the shutdown orders were lifted, then the COVID 19 transmission increased again. Another problem with this is that if it is not put in place everywhere at the same time, then the spread will continue in the areas that are not shut down and then spread to areas that have eased their shutdown again. That is what happened in the US.

I have this analogy that makes this easier to understand: When a farmers field with rows of crops gets an invasion of bugs in their field, and they decide to only spray insecticide on every other row, then the other rows of crops will continue with the infestation while the treated rows bugs are killed. After a while, the insecticide wears off on the treated rows and the bugs travel from the untreated rows and infect the previously treated rows again. Even if the farmer treats the first untreated row after this, the first treated row will continue to be infected. This could go on forever, or until all the crops are dead. This sounds stupid and it is! No farmer would do this. This is what happened in the US. Some states initiated a shutdown and others did not, so the COVID 19 virus lives on. Some places did partial shutdowns others only shutdown certain businesses, there was no consistent national guidelines, and the guidelines that were given by the CDC were either not followed or discredited by politicians, thus COVID 19 passed back and forth between states, causing the epidemic to go on endlessly until everyone has gotten the disease and millions could die!

5.

Personal Hygiene: One of the first guidelines to protect against the spread of COVID 19 was to have good hygiene practices such as, washing hands frequently along with using a disinfectant, not touching your face, sneezing and coughing into your elbow or a tissue, and not greeting people by shaking hands or kissing. Wearing masks was not recommended because the demand for medical and first responders was so great that it caused a shortage. It was thought that most of the transmission was from large respiratory droplets passing directly from person to person and being deposited on surfaces passing to people who contacted the contaminated surfaces then touching their faces.

These good hygiene practices are important but they did not stop the spread of COVID 19. After more research, it was discovered that COVID 19 could be easily spread through the air, not just by large droplets, but as an aerosol. Aerosol transmission is much harder to control since the COVID 19 virus is microscopic, free floating in the air, and can travel with the air flow both indoors and out. Just breathing out projects the particles a long distance and can even fill a small space in a matter of seconds. Outside it is not as much of a problem since the wind, if windy, will carry away the aerosol faster, but the disease still can be transmitted outside. Number 8 will discuss this.

6.

Disinfecting Surfaces: This is self-explanatory but it has problems also. Early on this was a recommended practice and for good reason. Infected droplets that land on a surface can transmit the disease to anyone who comes in contact with those droplets lasting for an extended period of time depending the type of surface. Early on people were even disinfecting their mail packages. Any typical household disinfectant can kill the virus that is on surfaces, so using them after every person contacts the communal surfaces is helpful in stopping the spread from shared surface contact. This is good but does not stop the spread of the virus as mentioned before, only slows it down.

7.

Avoiding Close Contact with Others: This is another strategy that can work in theory; keeping a certain distance away from others so the disease does not pass between persons, and avoiding congregating in groups. This is difficult since people are social creatures and feel the need to be close to others, but it has proven to help with the spread of the disease. Young people are particularly bad at this, (party on), and politics has also cast doubt and caused people not to stay a safe distance apart. Of course, like my analogy in 4, this does not work unless everyone does this 100% of the time and at the same time. As mentioned in number 5, the virus can travel long distances through the air as an aerosol, thus keeping a six-foot (two meters) distance does not prevent the transfer through aerosols. Thus the disease continues to spread.

8.

Wearing Masks in Public Places: This has been one of the most controversial strategies in the US mainly because of politics. Mask wearing to prevent the spread of disease has been around for more than 100 years. During the 1919 flu epidemic masks were also mandated, and effective in the start of the epidemic in 1918, but in 1919 people got tired of wearing them, and then the flu spread increased dramatically in the fall of 1919 with even more deaths than the year before. Sound familiar?

Yes, surgical masks do help prevent the wearer from spreading disease, that is why all surgeons are required to wear masks during surgery. An open incision is particularly susceptible to infection. A different kind of mask is worn by health care workers to protect themselves from infection from patients, called a N95 mask. This mask has valves that filter the incoming air and prevent microbes from infecting the wearer. Health care workers also wear protective clothing (PPP) to further reduce the risk of infection. The shortage of these materials was of great concern early on and caused many health care workers and first responders to become infected and die. Some citizens wore the N95 masks in public, thinking that they stopped the transmission of COVID 19. They were wrong. N95 masks only protect the wearer. If you have the disease, the N95 masks does not prevent you from passing the disease to others since the valves only work one way. When you exhale the valves open up and let your infected air pass through without resistance. That is why N95 masks are no longer allowed to be worn in public places.

As stated before, without 100% compliance wearing masks does not stop the spread of the disease. If one infected person enters a room, and everyone is wearing a mask but him, then he can infect everyone in that room. Remember that surgical masks only protect other people. When you breath in with a surgical mask and the air is infected you can be infected. Surgical masks do not stop the wearer from getting infected. They are not even 100% effective in preventing the wearer from spreading the disease. They are not a complete solution but can help reduce the transmission if everyone wears them.

9.

Testing, Tracing, Quarantining: This is also simple and self-explanatory. This technique was used in some countries as soon as the virus was discovered in their country, and it was successful at defeating the virus. South Korea is the prime example. As soon as the virus was discovered in China, the Korean government sponsored the development of a COVID 19 test. When the virus was discovered in the country (the same time as the US) tests were distributed where the virus was discovered. Testing centers were set up throughout the district. Temperature check points were also set up in all public areas. When someone was identified with a high temperature, they were led to a testing center and first tested for the seasonal flu. If they tested positive for the seasonal flu they were sent home. They didn’t waste a COVID 19 test on them. If they tested negative they would be sent to the next step and tested for pneumonia with a lung scan. If this test showed signs of pneumonia in their lungs, even if they had no other symptoms, they were given a Covid 19 test. They were then put in a quarantine area until the results of the test were received. If negative they were sent home. If the tests were positive, they were either sent to a quarantine center. (mostly hotels were converted for this), or if they were ill, sent to a COVID 19 ward in a hospital. They were not allowed to go home, thus not spreading the virus to their family members. This was the problem in the west. Most people who were positive, but not sick enough to be admitted into the hospital, were sent home to “self-quarantine”. Studies have shown that the level of compliance was extremely low, as low as 11%!  

When the South Koreans discovered a positive person, they interviewed them asking them who they were in contact with in the past weeks, called contact tracing. They then contacted all of these persons and had them come to the testing centers and were tested. If they were not sure where they had been, their cell phone records were checked to see where they had been. If the people they were in contact with were positive, rinse and repeat. This technique stopped the spread in South Korea and other countries that did the same. In a country with a population of about 52 million people, they had 27,799 total cases and 487 deaths! They did not have to close schools or any businesses! Unfortunately, this is only effective with a low level of infection as when it was first discovered. To trace 150,000+ cases a day is impossible!

10.

Disinfecting Everywhere: To end the pandemic the virus has to die! This sounds simple, and it is as simple as changing a light bulb, but a little history will help to explain and prove my point. There have been epidemics and pandemics throughout recorded history and probably before recorded history. There are different types of diseases that are the cause. The two main types are viruses and bacteria. They have various ways of transmission such as, through the air, water, animals, and insects to name a few.

Only two of these diseases have been totally irradicated, smallpox and rinderpest, out of the many scores of infectious diseases that are still killing people today. The smallpox vaccine was first used in 1796 and stopped the spread in Europe and the US, but still took almost 200 years to finally get rid of it. Other diseases, like cholera, were discovered to be caused by contaminated water from sewage, so sewage and water treatment prevent this disease from spreading, but is still a problem today in third world countries with inadequate water treatment.

The easiest way for diseases to pass from person to person is through the air. This is the case with COVID 19 and many of todays viral and bacterial infectious diseases. To make things worse, overuse of antibiotics has created mutations that cause them to be resistant to the antibiotics. This has been a particularly bad problem in hospitals with resistant diseases infecting patients. This is being combated with strict hygiene control and disinfecting operating rooms. The operating rooms are disinfected by a number of methods; with strong chemicals, gasses, and ultraviolet lights, all of which are toxic when exposed to humans. The problem with this is that once the patient leaves the operating room they are then not in a sanitary environment. Hospital rooms are kept clean but not sanitized like operating rooms, and thus the resistant bacteria is still a problem in most hospitals.

There is a way now to sanitize all living spaces and not involve toxic chemicals or ultraviolet light that burns the skin and causes skin cancer. It has flown under the radar of the media and politicians. I think that if all public and private spaces can be sanitized like an operating room, COVID 19 could be exterminated along with all virulent diseases that are transferred through the air and surfaces like the flu and many others.

You may have heard of UVC lamps that are used to disinfect operating rooms. The problem with them is that the spectrum of ultraviolet light they use is extremely dangerous when exposed to people. It passes through the skin, burning and causing skin cancer. In nature it does not pass through the upper layers of the atmosphere, like UVA and UVB ultraviolet which give you a tan and can burn your skin with too much exposure, and are necessary for absorption of vitamin D. This is why the astronauts need extra protection while in space.

In 2018 a new type of disinfectant lamp called Far-UVC was invented. This lamp uses a lower frequency, 222nm, of ultraviolet C light, less than the frequency of regular UVC. After testing it has proven to be just as effective in killing all viruses and bacteria, and does not penetrate the upper layers of skin and the outer surface of the eyes, thus making it safe for human exposure. This testing was completed in 2020 at Columbia University: https://www.cuimc.columbia.edu/news/far-uvc-light-safely-kills-airborne-coronaviruses

The lamps are available now from various manufacturers and starting to be used for disinfection, but I think that these lamps need to be manufactured and distributed with the defense production act to save as many lives as possible. The cost of these lights is high but will come down when production is ramped up. Of course this should be prioritized by where COVID 19 is spreading the most. I am not an expert but it is obvious where these lamps should be installed.

This is not just a solution to combat COVID 19, but a solution to combat all future communicable disease outbreaks and all communicable diseases killing people now. As in the past most epidemic and pandemics were stopped by improving public hygiene, like cholera, the various plagues, and TB to name a few. I think these lamps are the next step in improving public hygiene and making our world a better and healthier place to live in!

Alexa, Tell Me What is on the Table?

Posted on Updated on

Now Alexa can answer you and even recommend what to do with the objects like, what recipes can be made with them (if they are food items), or even tell you if you forgot something like your keys, wallet. lipstick, or credit card.

How can this be you may ask? The answer is… Smart Fabrics. You may have purchased a smart fabric, like the Christmas sweater with led lights woven into the fabric (my wife has one), or the sneakers that display messages (my son has three pairs), and a face mask that also displays messages (my son also has one). But smart fabrics have developed way beyond this. They are fabrics that can react to environmental stimuli. In other words, they have a brain! Now they are many and varied, like fabrics that react to temperature to keep you cool or warm. There are many smart fabrics being developed for the military, firefighters, police, and other high-risk professions.

The fabric that is being developed that can connect to Alexa, or any computer or smart phone, is basically a smart tablecloth! This is being developed and tested by a team of researchers at Dartmouth College.

The team made this smart tablecloth using capacitive sensing for object recognition. (Watch out, nerdy language!). They call the material Capacitivo (really original name, give them a break, they are just science nerds). Let me explain this nerdy term. This means that objects can be identified by sensing the electrical resistance, the shape, and the weight of the object, and It is not necessary for any user input to function.

The team made this material by using diamond shaped electrodes that are layered onto a cloth, a similar process as iron on t-shirt decals. There is also a layer of material that acts as a ground underneath the electrodes. When an object is placed on the cloth, the resistance of the material is measured along with the shape. The grounding material also helps to identify the object by measuring the resistance as an electrical current passes from the electrode to the ground. There is a special module that is attached to the material and is connected to a computational device, like a computer, smart phone, or Alexa.

So how does the computational device know what the object placed on the cloth is? The program that determines this uses machine learning to have a catalog of the characteristics of these items. In other words, it learns what the objects are by the response of the electrical signals from the cloth and module. Machine learning is a fairly new field of computation and is a form of artificial intelligence (AI) which is transforming our lives as I type this. AI is teaching robots how to respond without human input, as well as the development of autonomous vehicles, such as trains, planes and automobiles, (movie reference, one of my favorites), and many more applications like, research in medicine, physics, materials development, and weather prediction. (And not to program robots to take over the world).

The material was tested with twenty different objects and was successful 94.5% of the time. Just what objects did they test you may ask? Various objects were tested including, fruits and vegetables, a container, different liquids is in the container (milk, juice, whisky, etc.), how full the container is, and everyday items like a lipstick, and a potted plant. Alexa then can tell you when the plant needs to be watered, suggest recipes for the foods on the table, or tell you where you left your lipstick.

There are limitations though. Light weight objects, like a credit card, are not as easily identified because they don’t leave a heavy footprint that makes contact with the grounding material. It also can’t tell you if you are hungry or thirsty or drunk or stupid or tired or cheating on your wife or if your wife is cheating on you or burgling the house or hanging from the ceiling…..

I would love to hear back from you on your opinion if you think that people might actually buy a smart tablecloth. Of course people buy just about anything that is high tech and can be connected to a computational devise!

Here is a video of the smart tablecloth if you don’t believe me and think I am pulling your leg, (no it can’t tell jokes about the objects either), and at the end I will post some links for further reading:

How I Got the Nickname, “Perfect Pete”.

Posted on Updated on

It was my sophomore year in high school when I got the nickname “Perfect Pete”. I have had other nicknames throughout my life like Pete the Peach, Pete the Weatherman, and Pete when my voice was changing.

I was a band geek throughout high school which turned into my main profession throughout my life. A few years earlier in eighth grade I had started taking private trombone lessons from a young, but strict, teacher, Frank T. Williams III. He gave me lots of advise like “If you want to become a professional musician, one thing you don’t do is get married, and the other thing is you have to be a great sight reader.

I wasn’t worried about the first thing, but I didn’t get married until I was 43. Frank made sure I became a great sight reader by force. Every lesson he put some music in front of me that I had never seen before and made me sight read it. He taught me tricks on how to do it better, like looking over the music before starting and checking out the key and time signature, as well as spotting where the more difficult sections were.

After two years of private teaching I started to become a good sight reader. Many of my band mates were not. Before the school year started, we had a band camp and would learn new music and marching formations for the upcoming football season and competitions. During one band practice Jim Crumbly, our band director, handed out a new piece of music called “Gospel John”. I was familiar with this song since I had listened to it on an album of trumpet virtuoso Maynard Ferguson, but this was a different marching band arrangement. The music was quite challenging, so when we started playing most of my bandmates stopped playing a short time after starting. Mr. Crumbly understood the problem and said that it was OK because the music was so difficult. Then he gave us a challenge and said that if anyone could play through the music by the next practice they would get an “A”.

I then opened my big mouth and said, “I can play it perfectly today!” Mr. Crumbly had a startled look on his face and then said, “Go ahead and play it perfectly for us then!”. I then played through the music from beginning to end without any mistakes. Mr. Crumply then gave me an “A” grade and one of my bandmates said, “Way to go Perfect Pete!” and that’s how I got the nickname. I don’t remember which one of my bandmates said it but if they are reading this please comment below!

As for the subject for this blog on “Science Technology and Beyond” is concerned, I am also a bit of a science nerd, and even had college level courses on the Earth Sciences even though I was a music major. With so much negativity in the world, I wanted to write about something positive. So please subscribe to by blog if you like what I am writing about. I will try not to sound like a science nerd and explain everything in layman’s terms. Please let me know what you think.

Past Due Post: Tribute to my Mom and My First E-Book Sales Report

Posted on Updated on

On a Personal Note

September 15 is a date I will never forget. On September 15 2006 I was playing a gig with the Lisbon Swingers Big Band just south of Lisbon. As we were waiting to start our performance I received a call from my step father, Jim. He told me that my mom had lost her battle with Mantle Cell Lymphoma. I was devastated. I walked away from where we were waiting and found a wooded area away from everyone. I gained my composure but could not talk to anyone, and then we played the gig. This was the most difficult performance of my life. My mom was the most influential and special person in my life. Last year I wrote this article on Bubblews about her:

The Most Positive Person in My Life

Today is the 7th anniversary of the passing of the most positive person in my life: my mom. She was born Hendrika Charlotte Hilbers and despite many hardships in her life she always had a positive attitude. At an early age her and her family survived the Nazi occupation of the Netherlands. My mom endured bombings (she never liked fireworks displays because of this) and severe food rationing. My mom always made me finish all of my food …

A New Trick

I am a person who is always trying to learn something new. You may notice that I have a link to download my e-book on the right. I didn’t know that this could be done on WordPress until a fellow writer, Ana Spoke, blogged about how she figured out how to put a link to download her first e-book on her WordPress site. I posted her blog before this one, so check it out if you want to do the same. The link to her post is at the bottom of this page. I also did this because at my age my memory might fail me the next time I publish a book, so if I forget I have her post to remind me.

“Resveratrol: Just the Facts” Earnings Update

So here is what everyone is waiting for. Did my book “Resveratrol: Just the Facts” make me a millionaire? Not even close but some people have downloaded it. I offered it for free for the first five days and 68 people took the bait! Since then I have sold 5 more copies; 3 in the US and 2 in Great Britain. I have made $1.05 and .58 GPB. The Kindle select program also pays royalties for pages read and so far 122 pages have been read in August, but I have no idea how many pennies that will total.

YouTube

My YouTube revenues are continuing to trickle in but I have not posted many videos recently. So far I’ve accumulated $7.16 in revenue. Here is my most recent video from when we owned a gym:

Other Pay Writing Sites:

I am still a member of Bubblews but do not post there anymore. I will start to post more of my writings there like the article above. I have a balance of $28.33 and need to get to $50.00 before I can redeem my money. I don’t count on it since my earnings have only gained about $.05 in the last six months. Bubblews is considered a micro blogging revenue sharing site as well as another site Persona Paper which I also belong to. They both suffer from lack of ad revenue. So far I have earned about $.17. I have published one article there about how micro blogging sites don’t make any money:

Why Micro-Blogging Sites Don’t Make Financial Sense

Revenue sharing writing, and blogging sites are rapidly being started, copying the idea of Bubblews. I think these sites are a great idea but some are doomed to fail…

What I’m Working On

My newest project “The Vitamin D Conspiracy” is started but I have been doing some more research on the subject. I have a rough draft of the outline finished and will start filling in the chapters soon. I got some good marketing advice recently. The learning curve on marketing books and e-books is even steeper than self-publishing a book. One tip I got was to make a cover first before the book is written and start using social media and e-mails to create a buzz about the upcoming book. This sounds like a good idea. I think I will hire the cover design of this book out. I found a site called Fiverr.com that does this kind of work and comes highly recommended. Five bucks is not a lot to spend. They also have many other services for a fiver.

As far as promoting a current title I am at a loss other that social media. I have checked a few paid advertising sites. One seemed like it was OK until I did the math. They wanted something like $350 for an ad campaign that would average about 1000 sales. Each one of my e-books makes $0.35. That would only just break even! If anyone has some suggestion my ears are open.

My First E-Book is Now Published!

Posted on Updated on

Captura de Ecrã (4)

Yes, I finally pulled the trigger and self published my first e-book. It will be offered for free until August 4th on Amazon for world wide distribution at all Amazon locations. Her are some direct links for downloading:

US and Portugal

UK

Spain

Netherlands

Brazil 

If you download my book I would love to hear from you and your opinions. It would be even better if you left an Amazon review.

Now on to my publishing update. I did not post for a while for a few reasons: 1. I was working on my book, 2. I wasn’t feeling well, and 3. I just got lazy with the summer heat. I think the main reason was the last one. The final additions to the book were just tedious. Adding an index of the conditions that resveratrol has been studied was tedious but adds to the reading value of the book. This was all a learning process for me since this is my first e-book and using Word to write the book.

The uploading process to Amazon was a bit more complicated. I had a e-guide that is a bit outdated. It stated that I had to convert my Word file to HTML to upload to Amazon. After finally figuring out how to do this on Windows 8, I uploaded the file successfully, I thought! After uploading there is a way to review your book on all the e-book formats. I started to check and found all of my bullet indents were a total mess. I went back to the original HTML file on my computer and tried to make all of the bullets consistent, then upload the file again. No go, still a mess. After many hours of fiddling I decided to try an see what advice the Kindle help section could offer. I was shocked to find out that it was not necessary to convert my file to HTML and I could upload the Word file directly. I did this and wah la, everything looked great. I did find a few glitches and corrected them in Word and uploaded again, then hit the publish button.

I am now a bit more inspired to write and I am finishing the research part for my second book tentatively titled “The Vitamin D Conspiracy”. This subject is more involved and I feel that it is a very important one for everyone’s health on the planet.

I have failed to keep you updated on my YouTube progress. I have posted a few more videos and actually have earned more money than I thought. I keep on studying YouTube techniques like how to craft an interesting title. This is one of the most important things to get people to watch your videos. If you title your video with something bland like “What we did on Our Summer Vacation” you won’t get much response. Better is “How we found the perfect vacation spot” which creates value to the watchers or “We had a crazy fail on our trip to Safari Land” which creates curiosity for the watchers. I am currently changing some of my titles.

So far I have accumulated $6.33! Maybe if I change a few more titles I’ll get that video that attracts a million views! Here is a link to my playlist.

Update on Publishing my First E-Book: Tedious Work!

Posted on Updated on

On my previous post I mentioned writing my first e-book and giving up on Textbroker. Textbroker has since notified their writers that they are changing their terms of service. The one thing that stood out after I read this is that they set no time period for review of assignments. This means that there is no way to know when I might be reviewed and possibly moved up a star rating.

I have been on vacation this last week so I have not done much to get my e-book ready for publishing. The writing part is finished but the publishing part is not. Self publishers have to do all of the stuff that the editors and publishing houses normally do. Things like fonts, links, covers, legal disclaimers, indexes, advertising, and  proof reading, have to be done by the author or the author has to hire the work out.

I am writing this first book more for the experience and gaining knowledge on how to self publish than trying to get rich. At this time I have most of the above things done. Just fixing the fonts for consistency was a chore. I am now working on an index that automatically links the words to the place in the book that they are located. In future books I will do this as I write each chapter which will make things much easier. Learning to streamline this process is a main goal and will speed up publishing future books and e-books. Social media is also very important in promoting for self publishers. I have set up a Facebook page which is linked in the right hand column. I will have to explore more ways to promote my books.

Hiring an editor is an option for future books and highly recommended by many self published authors. I have more involved book ideas that this would be advantageous. Here are some tentative titles that I am considering and I would love to have any comments on which one you think I should start next.

In the health category:

“The Vitamin D Conspiracy”: Similar to my first e-book “Resvaratrol: Just the Facts”. This book talks about the history of vitamin D and how the US government bungled the recommendations for this essential nutrient, as well as the effects on my health and how vitamin D deficiency is being studied for many health problems.

“Bipolar Disorder: The Caregiver Experience”. This is a tentative title about my families dealings with bipolar disorder and how the medical profession failed us totally.

Family and genealogy category:

“The Autobiography of Emilie Jane Butterfield Loyson”. This is an unpublished autobiography of my great great grandmother that I discovered in a library. It was being edited by my great-grandfather who died before he completed it. She was famous in her time because she married a French Carmelite Monk. This is very topical today because of the Pope’s mention that discussion should be opened about the marriage of priests. I will edit this work or try to find a publisher.

“The Widow and the Monk”: This is the true love story of my great great grandparents Père Hyacinthe Loyson and Emilie Jane Butterfield. I have been researching this for more than seven years. This is a story of personal sacrifice for true love against all odds. Both of their biographies are more than 900 pages each and his is all in French. A real challenge but such a great love story.

Fiction:

“Our Crazy Downstairs Neighbor”  A story based on real events in my life but fictionalized. The basic plot is how a downstairs neighbor, who at first seems OK, turns out to be a destructive force in the main characters life.  Here is a video of the main inspiration for this book: 

Science Fiction:

“The Ants of the Galaxy”. The story of humans from an extraterrestrial point of view. How naive we are to assume that extraterrestrial’s would act with any similarity to us.

“Warped Into the Future”. The story of a test pilot who volunteers to test the first light speed space ship and upon his return finds a much changed world.

Personal journal category:

“Encounters with Greatness and not so Greatness”: My personal and professional encounters with famous people.  Stories that are inspirational, amusing, but not necessary all positive, about the famous people who I have met because of my music career or just by random encounters.

That’s all for now and I’ll post more ideas as they pop into my head. Please help me to decide.

Week Three and Four and I have had Enough of Textbroker!

Posted on Updated on

I have lost my desire to write for Textbroker. After spending most of my free time writing for people I don’t know and for subjects that are not interesting to me, I have decided to take the plunge and start publishing my own writing. My earnings were increasing at Textbroker only because I got better at selecting the best assignments to take, but I was still making slave wages. The week of May 14, I made a whopping $19.79. The next week I did better, $30.07, mostly because I took an assignment of 1200 words. This turned to be very time-consuming because it required a lot of research. I spent my free time for a whole weekend finding facts about the latest smart phone cameras, zzz…

Another reason I am not happy with Textbroker is that they still have not reviewed my assignments so that I can advance from a three star to four star writer. I was under the impression that this would happen on a monthly basis but I was led astray. When no review happened after a month, I searched the forum and found out many other writers were complaining about the same thing. Some four star writers had a review, then were only given a three star rating. They then continued to write at the three star level but did not receive any further reviews. Some had been writing for six months and others had completed 600 or more assignments with no reviews.

I have a theory why this is. When the site does not have enough three star writers to quickly complete the jobs that are on that level they simply give some tough reviews of four star writers so they get reduced to a three star writer. That seems logical, but it is not fair. I have done a time study of my work and I am working for about $3.00 per hour! One cent a word seems OK but most of the assignments require some form of research or reading which takes time. Imagine a 400 word summary for an article that has 3000 words. It takes time to read the article then try to include the main points into a blog of 400 words, spell check, proof read, and submit the article on the site. This would take me at least an hour and a half to complete.

I can write 1000 words an hour fairly easily, but not complete a writing assignment of 1000 words in an hour. This is why I will be spending my time publishing my own material.

The Image below is the screenshot  of the cover design of my first e-book that I am currently working on. I made this myself using Word. Any help or suggestions will be appreciated. Hopefully my next post will be announcing the release of this e-book!
