Yeah, funny but you don't hear the dark side of Edison's success, good
inventor, too bad he tried to use his inventions to gain monopolies, but
such is the corporate world.

Interestingly enough, from what I've read, Edisons original idea was to have
localized generating stations in every neighborhood, even each home having
it's own generator. Considering the problems of maintaining a massive
infrastructure as is required for AC power, time may show the ultimate folly
of AC, escpecially since many household electronics immediately convert AC
to DC before any other process. The trouble is, the power companies have
such a virtual strangle hold on the energy markets, the cost of bringing
competitive alternatives to the markets is enormous and would be priced so
high as to not be competive for quite some time.

We've looked into solar roofing products, even a natural gas fired turbine
generator, but the pay back is so stretched out, my grandchildren would be
dead before it paid for itself.

Interesting though, back to original discussion, at least to the point where
I hijacked it, lineman routinely hook up to live lines suspended on
platforms and other devices, the only ill effect being a queezy feeling,
which is due to the fields surrounding them when doing so, a mesh suit
apparently takes care of that.

I like to imagine the first person they tried that system on.

You want me to do what !!!???
