Asking Aleksander Zawada if he can design a dirty-cheap diy solar cell?

Probably wouldnt work. There is a maximum energy density per square foot when it comes to solar panels, so the act of generating anything useful powerwise within a given amount of space is quite the task- not just building, but designing efficiently. So to make a panel that you actually intend of connecting to anything, you either need a lot of space to run a whole bunch of DIY panels to pull even a few mA, or you need to properly design a panel, with a very high efficiency rating ( which aint gonna be cheap, and certainly not dirty.).

If you have the real estate, I believe there's a method you can use that utilizes cupric oxide (burn a piece of copper until it goes solid black, remove the black buildup, voila'). But the power return is paltry at best. If you want sun power, your best bet is to use a parabolic mirror array, focused on a reservoir connected to a steam powered motor and dynamo.

All you need to do is find a simple method of recondensing the steam (bury a bunch of pipe, run through a stream, throw it in the pool, etc..) , and you have a closed loop generator with a significantly higher power output than a commercially made solar panel of comparable size- and you could put it all on wheels.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
