- Steve,
-
- We use AC power because you can transmit high voltage
- great distances, and with AC you can use a transformer to convert
- high voltage / low current to low voltage / high current for use
- in homes. Otherwise power lines would have to be short, not over
- a few miles from the dynamo (generator). As it is, we can
- transmit power across state lines! AC is handy, and I believe it
- is healthy as well. I experimented on developing chick embryos-
- subjecting them to emp and emw radiations at exactly 60 cycles,
- various voltage potentials. No teratogenic or mutogenic effects
- were noted (they were healthy, even above expected). This leads
- me to believe in "something else is afoot" technology.
-
- We know for a fact that there is a high rate of cancer
- among people who live under power lines. Now comes MY explanation
- of this phenomenon. Power lines are ugly, they do NOT add to
- property values. When a power line goes up, people move away.
- The house is of low value now, and is disfavored by everyone- even
- to the people who buy it. The people who DO buy these houses do
- so because they HAVE to, they are uneducated and poor.
-
- It is also a known fact that there is a high rate of
- cancer among uneducated and poor people. The reason being, they
- simply do not have proper hygiene, sanitation, or eating habits.
- Often they smoke (higher percentage among the poor) and drink
- (same goes here too). It is known that a combination of
- cigarettes and alcohol SUBSTANTIALLY increases your cancer risk.
-
- In light of this evidence, I still feel safe in front of
- my video display terminal- even tho I can measure the radiation
- that is dropped across my body with a scope. Since it is still
- impossible to say WHAT caused the cancer in a subject, it may have
- been radon, smoking, work-related carcinogens, etc., doctors just
- have no way of knowing. People who stay away from all forms of
- risk still get cancer, it is a gamble. We do know for a fact that
- it is a total picture of risks (additive, not singular) that give
- rise to cancer related illness. Normally healthy animals do not
- seem to have a risk when exposed to electromagnetic radiation.
-
- Maybe it is a combination of factors. We don't know.
