Ionospheric antenna get 5 KW free !

I bought an electronics kit at a yardsale and put together a crystal set from it and got .04 volts output from the earphone wires.I figured that 20 crystal sets going into one battery (20 times 250ma=5 watts per hour)might keep a battery topped off,if you don't use it much.Triffid

5 Watts per hour? The "watt" is a unit of power, not energy. So perhaps you mean Watts x hours, or Watt-hours, or Watt-seconds which is the same thing as Joules of energy. For example, a 5 watt bulb, left on for 1 hour, dissipates 5 watt-hours, or 5x60x60 watt-seconds or Joules, of energy.
The statement "5 watts per hour" is incoherent.

Your equation "20 times 250 mA = 5 Watts per hour" is just wrong--if your crystal set produces 0.04 volts and somehow supplies 250 mA at that voltage (which I strongly doubt), then 20 of them will produce (20 units x 0.04 volts x 0.250 amperes) which, according to my calculator, equals 0.2 Watts of power. The time doesn't enter into it.

Ionospheric antenna - very nice - but what it costs to try it
Perhaps $10M or more for keeping this "antenna" one day in such high altitude
Is it very "free" for 5kw
At that every kind of storms ... oh dear ...
In outer space we can find a lot of different energy - very expensive to go and try

I mean't to say  250 microwatts not milliwatts and maybe its not possible to hook up 20 crystal sets in series.Sorry .I did get .04 volts from one crystal set.Free energy to me anyway.Triffid

I had one year of college physics and remember that getting the units right was part of the struggle for everyone.Triffid
