Parasols are good for more than just decorating those fruity tropical cocktails. For example, Parasolar, a design concept by Oded Shorer, has an easily carried case that opens up to reveal a cloth canopy with integrated photovoltaic panels. Neat.
Holding it steady in its base is a battery that’s charged up by all that solar energy, and you can tap into it via a 12v outlet or two USB ports. And hey, if there’s no sun that day, it looks like it might also function as an umbrella in a pinch. The symbiosis of combining shade and solar energy just makes sense.
