Frank, is that an incandescent 100W light bulb, or the flourescent or LED equivalent
I can't even spell half those words, but I'm guessing 100 Watts of equivalent solar light. Do you get 100 Watts back or less/ more than the 100 watts taken in? I do have an interest in solar powered aeroplanes, but can't believe how they work. Also a Toyota Prius with a Hybrid set up is fairly expensive, so what do I get back for the extra output of cash?
