I like this. Imagine if you took something like this to the desert, you could have the means to convert sand into silicon without needing to use a locally-sourced fuel to generate the required heat (For what it's worth, I realise the sand that goes into silicon wafer production usually has to be purer than commonly-found sand, but I still think this production method may prove useful, perhaps for the silicon that goes into solar panels).

you would still need carbon for reducing the silicon dioxide into silicon

You mean like this?

It's an artist's project but he IS melting sand.

See also this godzilla of solar plants :) http://www.fastcoexist.com/3057288/this-huge-new-solar-farm-...

>By 2020, China plans to build 10 more—the equivalent of 100 solar farms the size of Crescent Dunes.

The ability of china to scale never ceases to amaze me.

As the article suggests, the Mt Louis Solar oven was a prototype that lead to the real godzilla, the Odeillo Solar Furnace:

This thing is massive and a beauty to look at. I remember going through the tour in the 90s, there were very thick steel plates on display that where melted like butter in the center it was really impressive. https://books.google.fr/books?id=VQEAAAAAMBAJ&pg=PA88&lpg=PA...

I'd be interested in the health and safety of working around these systems.

It feels like the sort of thing it would be very easy to forget the danger of as there's minimal moving parts and no scary sounds.

Surprised a henchman hasn't been thrown into the danger area in a James Bond film yet.
