Former Microsoft Tech chief Nathan Myhrvold wants to dim the sun's rays with liquid sulfur pumped from helium-filled balloons. But it's not like he is sitting behind a desk, tapping his fingers together muttering "excellent" or anything.

In fact, the idea is intended to save the planet from the scourge of global warming. The "Stratoshield", as he calls it, would spray what some would consider an environmentally acceptable amount of liquid sulfur into the air through a 15 mile long hose attached to a helium-filled balloon. Apparently, the sulfur would dim the sun's rays, effectively cooling the earth in an emergency situation. Yes, it sounds crazy (much like the hurricane defense system he proposed with Bill Gates) but keep in mind that when filthy rich captains of industry have kooky ideas, lots of other people take them seriously.
