WorldChanging: Gorlov’s Helical Turbine Interesting technology, but more interesting this statement: “There’s also the question of what happens when major flows of water see a 35% reduction in energy. Gorlov suggests that 656 full-size turbines could capture sufficient energy from the Gulf Stream to power North America — but what happens to the Gulf Stream after losing some portion of its kinetic energy?” Reminds me of some thoughts I had previously about “hot rock” technology. As an aside – I asked one of our climate change folks about hot rock, specifically about potential impacts of energy transfer on that scale. He didn’t have an answer on the spot, but I will follow-up and report back soon.
Davos Newbies: More hours, please This is one of the great dichotomies facing the fair trade movement, and why there are generally provisions in fair trade definitions/charters for the inclusion of worker representation (i.e. from local unions or worker’s delegates) in decisions. It also shows that the best intentions can go awry for the most unexpected of reasons (but I also think a good sign that companies are listening and trying to do the right thing, however imperfectly).
Alt-Energy.org: Alternative Fuel Cars: Plug-In Hybrids and Electric Cars Interesting just how much car companies are underestimating demand for alternative energy vehicles. Reminds me of the time that AGL in Australia could not offer green power for about 18 months because it could not supply that demand (I think that was a bit of a cop-out by the way, but indicative of how far behind the eight-ball some energy and car companies are).
