Solar Box Cookers Only Work When the Sun is Shining – So What?

“By now, I suspect, some of my more skeptical readers will doubtless be jumping up and down, eager to point out that solar cookers aren’t viable everywhere, and only work when the sun’s shining. This is of course true, but it’s also beside the point. Nothing in the appropriate technology toolkit is suited to every context – that’s one of the implications of that word “appropriate,” after all – and nothing ever again in human history will provide our species with the kind of instant, context-free torrent of energy we now get from fossil fuels. Once those are gone, the entire approach to technology that’s built on the assumption of abundant, highly concentrated, highly portable energy supplies goes whistling down the wind, and the approaches – in the plural – that will replace it are going to be less convenient, less portable, and less capable of ignoring the rest of the cosmos than what we’re used to”.
