But I understand what you are saying. We could get 3x type heat out of the same solar system. Just don't see how you pull it off.
I'm any case we need coal for reducing the ore to steel. How does one manage the chemical uses for coal.
Theo Fidel, the article talks of in-situ heat radiation. They make two points. One, most industrial processes require heat in the region of 300-600 degree celsius. Two, technology has developed to generate 2000 degree Celsius using solar heat radiation. It even has some images. Not being an engineer and my school level science is inadequate for this purpose, i wasn't sure if the authors were talking of something really credible or it was just one of those popular science books of the kind USSR used to specialise in and which were available in local libraries in our school days.
I wonder if you can attempt a critique of that article and post your comments here. It will be education for us finance types.
