The sophisticated engineering, delicate structure and graceful flight of solar-powered aircraft is a beautiful vision in efficiency. A formation of fighter jets makes the very skies thunder and the ground shake, exciting in its power. This dichotomy is everywhere, especially machine racing sports. So where can environmentalists and energy efficiency enthusiasts get the excitement of power without the indulgence of excessive wastefulness? And where can people who love seeing jaw-dropping power get fired up by green technology without having to develop an appreciation for boring economy? [more inside]

Hi, within planning to build an eco house within the UK, would it possible to get some recommendations for woodburners that have a good efficiency rating or a reputable brand that makes woodburners. (Also possibly considering over woodburners as well as standared ones.)

I am working towards developing an energy education for local schools in Northern California. Does anybody have any helpful resources or places I should look? Unfortunately, I don't have anything to narrow the search as this could encompass anything from k-12. Resources can include curriculum, print outs, science kits (within a reasonable budget), competitions, etc... Pretty much anything that would get kids interested in renewable energy and energy efficiency. Any and all help would be appreciated!
