What should be the minimum requirement to consider one's self solar powered?
My definition would include a portable PV system to power a light and a laptop in the backcountry but would not include pocket calculators or the self-contained LED yard lights that stake into the ground.
I think if it serves a real energy need and is powered from solar, wind or hydro then it qualifies. How's that for a broad definition? What about a PV charged flashlight? I'd say yes, if you use it regularly. But the PV powered crystal spinner I have on my window, although cool, does not exactly increase my empowerment.
What do you think?
