The world needs a new source of energy, an unspillable source.

What can anyone tell me about good portable solar power equipment?

I’m doing research on portable solar equipment, and there are a lot of companies out there that I’ve found. Anyone have any ideas as to what brands will hold up for long periods of hiking and driving? It would need to be able to power batteries for laptops, camcorders, and probably some smaller equipment like cell phones, iPods, etc.
