Mit Parabolic Dish

The folks @ MIT are warming up to the idea of parabolic solar collectors, recently demonstrating this 12-foot dish of massive heating power -

– the completed mirror focuses enough solar energy at its focal point to melt solid steel. The energy of typical sunlight is concentrated by a factor of 1,000. This was showcased during a demonstration, in which a team member held up a board, which instantly and violently combusted, when brought within range of the focal point.

Hmmm … can’t help but imagine pitting it against the Light Sharpener in a ‘solar-ray-deathmatch’ – MIT Students Develop Solar Dish(Thanks, Noah!)From the pages of MAKE:
