Solar Furnace

Thanks to George:

I found this video extremely interesting. It is a video of convex mirrors focusing sunlight on one direct point. The video speaks for itself but I love how the two men doing the interview stand so closely to the extreme heat. The video was filmed in France in the Solar Furnace Research Facility. It probably takes a large amount of time and effort to get sunlight to focus that well. The amount of heat generated is just ginormous and I feel like their are scientific values to this device, maybe an easier way to melt steel.
