EcoGeek

"Sexy photos of a Solar Furnace in Uzbekistan" is an actual post on EcoGeek. What's more remarkable: the photos are indeed sexy. Who knew that a solar-powered aluminum smelter in the former Soviet Republic could be so stunning? EcoGeek is porn for hardcore science, tech and enviro freaks: the site's posts run the gamut, from hybrid cars and air-powered motorcycles to sustainable, eco-friendly dollhouses, plus practical guides for "decarbonizing" your life. EcoGeek focuses on the minor miracles that promise to make our world cleaner, and if you spend a few minutes here, you'll find that the true geek's astonishment and awe at the beauty of science and technology are really contagious.

Sample EcoGeek post: [A] Chipotle burrito with beef, beans, cheese, sour cream and guacamole comes in at an astounding 1,300 calories. Bust a gut with one of those and you'll find enough energy to travel 37 miles. If it were gasoline instead of a burrito, those same calories wouldn't even get you a full mile. So why is the human body so much more efficient than automobiles?
