extracting power from plants?

Sorry wrong patent.5794601 is still an interesting patent.I'll repent now and get the right patent number here later.Triffid

ok,heres the correct patent number"2,813,242 by L.R. Crump,March 12,1954.He increased the voltage a hundred times,not several hundred.So using al least part of his circuits.You should be able to get 250-300 volts out of a tree battery.triffid

thanks Triffid!

will study the patent soon.
If we really can multiply the voltage 100 times
without lowering the already very low amperage,
then indeed, this could be a grand improvement.

Just imagine hooking a couple of trees to such circuitry,
and getting a nice (converted) 220V AC out of an attached
wall socket...
you could mow your lawn using power from your trees,
recharge your car batteries from your garden trees,
perhaps (if you have enough trees) even run part of your
house on it...

It might be possible to recharge car batteries from radio waves.So the patent shows how to take the ac from the radio waves, convert it  to a steady dc output,then using a transistor circuit interrupt it  and make it go through a 100 gain transformer and make it at least pulsed DC.All from 1954.
There are references to earlier patents too.triffid

@ triffid:

I have always wondered about "intercepting" RF signals for power.  After all, they are there anyway and the radio or TV station will not know, or does not care if some of the energy is used by someone like me.  It will not prevent anyone from receiving the signals, and, it will not make them up their power to compensate.  I have had this idea for a while now.  I am glad someone else is thinking along the same lines.  It is already there.  Let's use it.
