Just a quick Idea™…
I think it’d be pretty damn nifty if someone could throw together a solar powered umbrella device (ala SunBrella), only have it truly be self sufficient.
- Long term battery storage of any accumulated light.
- Built-in radio, a/c, and water condensor.
- The ability to prioritize power consumption.
Throw in mp3 players, or usb plugins for charging cellphones & ipods on retail versions. refill a water bottle in an hour, or include speakers. Integrate military versions to include gps, or condense water right into a camel back.
Just an idea…
