I thought this would be interesting for some rubber tramps-
It looks as though the solar power soaker (forgetting the name for them currently) doesn't put out much energy, and you have to buy your own battery pack, but I think the idea is still pretty nifty, even if you can only find a battery pack the right size with USB ports. With the growing number of ports in cars I'm fairly certain there are USB powered camping items out there, such as flashlights. (Too tired to google.)
I especially like that it opens up on two sides rather than one. Tents are miserable in the summer but often necessary when camping in treeless areas that have showers, so opening it on either side would mean airing it out easily with a cross breeze, as well as being able to open it on whichever side the rain isn't coming from, rather than having to move it completely to still have air flow but keep the rain out.
Anyway- off to bed! I hope at least one of ya finds this interestin'! The video is a bit doinchy if you ask me.
