solar concentrator that melts steel

[Christophe]

There is a simple application of solar cooking oven, interesting for hot and sunny countries *, with concentrator or not. Concentrator models are significantly more complex, but run faster.

* I specify because the two do not necessarily coincide ...

It is necessary (a little) concentration to obtain cooking temperatures ... the simplest model is the Ulog oven with double concentration (which can go up to 150 ° C): Solar-thermal / solar-oven cooker-ulog-build-and-performance-t10753.html

True to my habit of asking naïve questions ... apart from grilling sausages and making holes in steel plates, what are the applications for these solar concentrators?

Uh replace nuclear power plants and coal and gas ???? Just for example ... But the DNI in France does not allow it ... the DESERTEC project has done the trick of the question: https://www.econologie.com/telechargeme ... -desertec/

.the DESERTEC project did a good job of

The Desertec project and its DII suite proved above all that it was completely stupid to want to supply Europe with electricity from production facilities in North Africa. And it would already be good if North Africa is itself fueled mainly by renewables.

The concentration is not strictly necessary, because a closed enclosure of a window is sufficient to obtain a low temperature cooking, but it appeared that the constraints that result (start cooking early) are often poorly suited to and customary customs.

Concerning the relevant remark of Sicetaitsimple, this project Desertec transpires (sic!) neocolonialism ...
