Is it possible to use a 9v battery in replace of 2 AA batteries? Would there be any bad effect (ie. fire). Plus would it be possible to charge the 9v while it is in use? This is just for a test/experiment.

I want to build a parabolic solar concentrator for the production of photovoltaic energy.
It's possible to use the normal single crystal solar cell with a concentration of 40 sun and one heat dissipation system, or I must search special solar cell for concentrated photovoltaic?
Thanks

I have a circuit that operates at about 7amps. I need it to operate at that current for about 15 minutes. How do I compute how long a battery will last based on its mAH rating?

For example, say I have a battery rated at 1800 mAh. How long with that battery last in a circuit drawing 7amps?

Thanks

Ok I don't believe ID is science personally and I am not on the side of those who do, but I read about about a guy who is trying to publish his data on a computer algorithm to detect whether something has been designed or if it occurs naturally. I think aside from the intelligent design nonsense this would be a pretty big computer science achievement in the field of AI, anyone else think this idea actually has merit

I know that it has something to do with the "eye", but how exactly does it know when to flush? I'm guessing when the eye "sees" the water? (no more bottom obstructing the water).

Things that make you go hmmmm.
