Now that you've mentioned it, I cannot simply forget it. =)

Were ya lookin for info on running a solar powered mobile shop?

If so, I have some links to places where you can purchase solar equipment to do so. I recently investigated this same thing and you can actually do it relatively cheaply.. well, it's not cheap to start up but if you go to car shows and race events, it will save you a ton of money on booths with access to AC power.
