Recycling old batteries into solar cells

Proposal could divert a dangerous waste stream while producing low-cost photovoltaics.

leaving a large stockpile of lead with no obvious application.


Leaded petrol was always worth loads more than unleaded.  They could take the lead from the batteries, and convert unleaded petrol back to leaded petrol, and probably end the economic crisis while they're at it.

Yes, I will have one. I want power sources everywhere, even on cloudy days.

I want to try it with hydrogen.

A totally new energy supply technology for mobile electronic devices. Efficient and remains independent from the power grid.

If you watched Fox News on a TV hooked up to the shit powered generator, would that make a perpetual motion machine?


No, you'll create a positive feedback loop, overload the generator, until it explodes, leaving time and space itself in ruin.

As for hydrogen storage


But how are you going to collect hydrogen at home without using electricity in the first place?  Can probably be done, isn't immediately obvious how.

Not planning to collect hydrogen without electricity. Planning to use photovoltaic panels.

The problem is that hydrogen can't be easily stored at all. Or, yes it can, but most of it will have evaporated once you get around to using it. The atoms are so small that they diffuse through the walls of any tanks you may build, which is also the reason why it can't be sensibly transported through pipelines.

That's not a matter of minutes or hours, of course, but if I got that right, after only a few days there's considerably less hydrogen left than you'd expect.

This is the main reason, BTW, why there are no hydrogen powered cars on the roads today although German manufacturers have invested massive amounts of money into research for decades now.

Found what I was looking for.

DLR Portal
Scientists at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) have developed an entirely new kind of drive concept to extend the range of electrically powered vehicles.

#^LED Tubes Will Make Fluorescents Seem Old-Fashioned

Image/photo

Cree, front-runners in the scramble to replace traditional forms of illumination with greener LED sources, has just announced the release of a new type of tube light designed to tackle one of the biggest energy hogs in Corporate America: fluorescent overhead lights.

I'm having serious difficulty imagining this producing the amount of energy that it requires to push it through the air.

Strap This Wind Turbine To Your Electric Car and You Can Drive Forever


Image/photo

Electricity-generating windmills churn out free energy as long as the wind is blowing. So strapping one to the roof of your car where there's always a breeze as long as you're driving just seems obvious. The Transport Turbine--seen here as a 3D printed proof of concept--puts four small wind turbines on the roof of your car that generate electricity as long as you're driving at least 25 mph, with minimal drag so as not to affect your gas mileage.

A lot of mis-information or "misleading" information on that page. No you're not going to get perpetual motion. It will just slow the drain of the battery. And if you're stopped and the wind is blowing, it might help trickle charge it.

I will agree with you on the trickle-charging in the wind (or going downhill).
