Solar power has lots of potential as an alternative to fossil fuels, but some of the things we use it for make more sense than others: From solar-powered food carts, airplanes, and vending machines to solar-powered dog sweaters and beehives, read on to see which innovations are truly bright ideas -- and which ones are a little dim.

This petite theater seats 8-12 adults in what used to be a two-berth caravan, and it receives its power from four lithium ion batteries -- which, in turn, get their power from 120W solar panels.
