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.
