Ten Most Extreme Substances Known to Man | Ten Most - StumbleUpon. Aerogel: See-Through, Strong as Steel & Ligher than Air. Despite its incredibly low density, aerogel is one of the most powerful materials on the planet.
It can support thousands of times its own weight, block out intense heat, cold and sound – yet it is 1,000 times less dense than glass, nearly as transparent and is composed of %99.8 air. The lowest-density silica-based aerogels are even lighter than air. Despite its fragility in certain regards and its incredible lack of density, aerogel has amazing thermal, acoustical and electrical insulation properties as illustrated by the images here. A single one-pound block can also support half a ton of weight. Fuel cell - Wikipedia, the free encyclopedia - StumbleUpon. Demonstration model of a direct-methanol fuel cell.
