Free Energy From Diodes

[xee2]

@ schuler

I put an RK44 diode in series with an antenna and it did not rectify the weak mV signal being received. I then replaced RK44 with a germanium diode and it did rectify the signal. So RK44 may have low forward voltage drop but they do not make good detectors.

@ Anyone... I realize I am probably in the wrong forum, But can someone help me ??

I Have some of those wafer thin solar cells  .5v @ 3.5 Amps,  and I want to make a panel up of around
4.5 - 6 volts @ only  1 Amp, I know I can wire them up to make 4.5 or 6v but can I reduce the current somehow from 3.5 to 1 Amp without loosing much on the volts side ?

Germanium is very efficient up to 40% to 50% it also has the widest band gap, one thing I never tested on Germanium is if it is sensitive to Infrared.

The idea of diodes as energy accumulators has been discussed in other threads (can't remember where anymore) as well.  I am hoping to take an old LED computer screen to see if I can collect radiant energy from that. As a diode (or grouping of diodes), it should be able to accomplish this task. Unlike solar panels, diodes should be able to collect radiant energy any time of day, as should any piece of metal (with its inherent crystalline molecular structure) - see Tesla's apparatus for collecting radiant energy.

Someone also mentioned using a bifilar coil and a secondary with diodes.  Again, in another thread, the self-inducting properties of coils has been noted. Is this not why coils are found in many of Tesla's patents?

hi freepow

yes, you can - use a Pulse-Width Modulation circuit with the duty cycle adjusted to give you whatever proportion current you want from the panels max o/p

this means you get to use as much of the voltage as possible but essentially you're varying the load impedance to just draw your preferred current
