Got there just in time for cat 5 Hurricane Mitch and was on the second plane out after the airport reopened. Sorry peasents, no solar ovens for you!
But it is really easy and they do work.
Me, I'm stepping up to a bigscreen tv solar metal forge! Search youtube for instructional.
Pic related, muh junk Sony from the alley. Seems a shame to strip it, but it really is junk.
The fresnel lens is what I'm after.
Srsly, check youtube and prepare for a new scale of imagination!
