[Skunkworks] Solar powered street lights == power for small home?

Good people, I am increasingly fascinated by the solar powered street lights I keep on seeing around, I saw a couple of new ones near the Museum. Question: anyone know exactly how these work? Is the power stored somewhere? How much does a single "unit" cost? Can it be combined with a small'ish wind turbine? And most importantly, assuming I could afford one unit, would be sufficient to power 5 laptops? I look forward to the day I shall be completely rid of KPLC from my life.
