Ah, that is interesting ... and very DIY ... although the water doesn't get as hot since it is not evacuated (much less insulation) ...<div><br></div><div>Here is an evacuated tube panel for $400 .... could provide boiling water for the camp ... </div>

<div><br></div><div>I've done some minor experimenting with a few designs. If you'd like to meet and discuss ideas and possibly work on them - Sage or anyone else - I would be all for it. I know I've briefly talked to you (Sage) before about it in camp. If you feel strongly about testing this I could begin more serious prototypes at the start of next week after the new pedal generator designs are finalized. I am really interested in doing some solar cooking in camp.</div>
