The heat would be removed by the cooler that a small pv panel in a concentrator would necessarily have. That heat could of course be recovered for other uses.
The ones used as cooker would have the focus point outside the bubble. You could always use a zip-lock opening but you would need to make the bubble from high heat plastic, like turkey cooking bags.

That glorified beach ball is fine for a concentrating mirror to up the power out of a small PV panel, but where does the heat go inside that air filled bubble? If you use one of those inflated beach balls as a solar camping cooker, how do you open the beach ball to put your food inside and take it out without making a big leak? -------------------------------------- Spaceman Wrote: Someone marketed an inflatable reflector years ago, with clear front and mirrored back, but I haven't seen one lately. I think if I had an inflatable reflector I might just leave it as is. It would be great for those wilderness camping trips. ------------------------------------ Yahoo!
