I don't understand what good it would do buying another solar panel. Without some kind of battery to level out the variable power input (solar energy is not a constant) you're either not going to have enough voltage/current or you'll have too much. Besides, most laptop chargers use weird...

I don't think it would be very efficient to do it that way. First of all, if we assume the power input is going to be renewable, likely solar, then efficient is key. Plus, the computers are going to be very low voltage, probably not even a laptop but an ultra power pc for some home functions...

If I had a big car battery and wanted to charge a smaller battery with it (say a laptop), how would I do that without breaking the laptop? First of all, a battery has a certain voltage and DC current which is the same thing a laptop battery uses, but you'd have to ditch the AC adapter because...
