This could be a huge leap forward to new kinds of production: the Solar Sinter Project from Markus Kayser. It is some sort of production unit, that is able to work only driven by the sun. It can sinter objects out of the desert-sand, by using the direct sunlight through the lens, in order to “glue” the sand together. Sintering is some sort of 3d-printing. Ok, I would say, that you would in fact need sunlight like in the desert to make this robust and stable work. But at least it works and looks awesome cool (especially the “office”). (via)
PS: We made also some solar-cooking experiments lately with Regeneractiv at the Dingfabrik. Here is a video.
