Solar/Radio Cell Arrays From Germanium Diodes
« on: June 26, 2009, 07:14:16 PM »
Something I use to play with a long time ago was little Diode Cells that converted Solar and Radio Radiation to Electricity.

you can use old Germanium Diodes from Electronic junk. you can make very large panels and resale the power back to the power company if they are large enough to put out some good watts.

I have herd of these diode arrays before but I thought that it would take hundreds of thousands to get any real usuable energy from them!

You can pretty much determine the output in direct sun light with just one Germanium Diode, check it for Volts and then for mA and then multiply the needed amount of Diodes hooked in Series and Parallel. Radio Stations in local proximity will add to the radiation to be converted to electrical needs.

You can also use Silicon Diodes but they do not produce as much electricity as Germanium, you can also mix and match.

Smaller Cell arrays could be used for charging batteries or running small electronics.

All I want would be 1.5 to 2 volts dc at 200ma-300ma! Do you know how much that would take on average (city living)

@stprue

Take the leds from last night , put a DMM on it and test in the sun ...

Led works good in the sun , but it is still cheaper to buy a solar cell.

I did not know this...very interesting!  Hey would you mind giving me the spec's for one of your higher powered JT in the JT topic ie winds/gauge/style/outputs?

Thanks

Hi sptrue

You´re thinking of PaulLawrences or CharlesBrowns diode arrays, said to produce vge from quantum noise and will work in fully shielded boxes but require many millions of junctions using nanofab to be practical.

Any PN junction will generate power in sun. For example crack the lid off any canned power tranny and use a lense to focus the sun onto the die and you can get some real useable power. You can get a few watts out of a single tranny with a good sized die.

I think there´s a thread somewhere on OU about this, perhaps someone remembers the name of it.

Very interesting topic...  :D I found on google that we can build a home made diode from aluminum and chromium metals. I think its a lot cheaper than buying hundreds of diodes.... Or is there commercial microchip containing diode arrays? Miniature diode perhaps?

Charles M. Brown and Paul Lowrance both put forward the false idea that a diode that gates current flow based on voltage potential could be used to gate based on energy potential.  Brillioun disproved their faulty ideas decades before either first professed them.
