[AReU] Shocking

[Ray, W4BYG]

When I was much younger and more foolish, I had a kilowatt mobile on 40 and
75 meters mounted in a 1962 Dodge Polara.  It consisted of an SBE-33
transceiver and a P&H LA-1000C.  The amplifier power supply drew about 100
amps at 12 volts on peaks.  

When I wanted to impress someone with the level of RF/antenna power, I would
tape a long florescent tube to the antenna and let it glow on transmissions.


It was an interesting sight watching people's reactions when driving down
the road at night and transmitting.  (It was also known as the only car in
Jacksonville with "modulated" headlights.  The factory alternator was only
good for ablout 60 amps max).

According to FCC standards on RF exposure, standing close to a continuous KW
for an extended period of time, can be injurious to one's health.  

So regarding the article referenced below and the level of powers involved
in powering a home (many, many kilowatts), why would anyone propose living
amid an intentional 60 Hz magnetic field amounting to so many kilowatts.
The induction process can be done in limited circumstances and with limited
power such as a light bulb or recharging headphones or cell phones in a
magnetic stand, but it doesn't seem reasonable or practical for the proposed
idea.

Although much lower in frequency, it would seem very strong 60Hz
multi-kilowatt magnetic fields for long periods of time have to have
important human limitations also.  Maybe a little like living and sleeping
inside an MRI day in and day out?

Thanks for the interesting article, Bob W.
To me, this idea is a very old one - it's how the power gets from the
primary windings to the secondary windings in a transformer.
I know another way to do the wireless trick:  Capacitance.  
I have been wanting to play around using homemade capacitor plates to
transfer power through a window pane to run an electric device outside
without drilling any holes in my home.  

I do see a potential problem in creating electrical fields in a home as
unwanted induction.
A pacemaker lead suddenly gets the energy from a coil Possible AC hum
brought in through unshielded speaker leads Radio and TV reception
interference In extreme cases, electric shock to the victims inside the
home.  
Wonder what a 'wireless light' would do to a nearby electric watch, hearing
aid, computer, video game, blue tooth or a cell phone - not to mention the
magnetic strips on our driver's licenses and credit cards.  
Homeowners can just put the power in the air and watch the magic of
unintended consequences.  

I think it's funny that people would worry about the "cancer risk" of living
near 'high tension' electric lines and those who believe cell phones cause
brain tumors might willingly move into a "wireless" home.
