Just in case you thought the amount of woo in the world was diminishing, here comes an author to restore your faith. Randall Dale Chipkar has written a self-published new book that explains how your motorcycle is giving you cancer, The Motorcycle Cancer Book (http://www.motorcyclecancer.com).
As you know, a motorcycle's engine incorporates a magneto that generates electricity to power the spark plugs, fuel pump, and other systems needed to run the bike. There is nothing about this unique to motorcycles; the same basic system is used in virtually all internal combustion engines, like those found in cars, boats, lawnmowers, radio controlled airplanes, even the jets found in airliners and cruise missiles. So why the beef about motorcycles? Why, because that engine is right near your groin!
But not to worry. For a mere $109.99, Randall will sell you his RiderSaver™ motorcycle seat accessory, a flexible stick-on barrier that he claims will protect you. This special barrier will protect your groin from the evils of that magneto's proximity, and “put true freedom back into riding motorcycles!”
Randall has, apparently, overturned vast bodies of knowledge with his startling discoveries that these everyday devices have been giving us all cancer for more than a century. He describes the mechanism as ELF EMF (extremely low frequency electromagnetic radiation):
Many motorcycles generate potentially carcinogenic ELF EMFs directly into the rider's groin flooding the entire torso. This increases the risk of developing lymphomas, leukemia or cancers of the prostate, testicle, colon, bladder, kidney, liver, pancreas, stomach, etc. Both the heart and immune system are also at risk for disorder or malfunction. Infertility, sterility, erectile dysfunction, impotence, prostatitis, benign prostatic hyperplasia (BPH)-prostate enlargement, urinary problems, infections and loss of libido could also be side effects of excessive ELF EMF radiation penetrating the groin.
There are two fundamental problems with Randall’s claim. First, EMF from an engine’s electrical system is not ionizing radiation; not anywhere close to it. This means that it does not have the ability to strip away electrons, thus changing or damaging cells or DNA in your body. In summary, such an electromagnetic field cannot give you cancer.
Second, his product cannot possibly shield you from this. The only way to block electromagnetic radiation is through the use of a Faraday cage, basically a metal screen. And while you certainly could embed such a barrier into a flexible material, that does not appear to be what his RiderSaver™ is (though he declines to give a specific description). Regardless, static and ELF magnetic fields cannot be blocked at all, through any known method. This is basic stuff that you need look no further than Wikipedia to understand.
In short, he has invented a problem that cannot possibly exist, and offers to sell you a solution that could not possibly address the problem he invented.
Whenever someone claims to have overturned basic science and offers a for-profit solution, you should always be skeptical.
