It seems like a strange question, but have we run out of good places to build wind farms? On the face of it, one would think that a country as large at the U.S. is a long, long way from a time when we don't have the space to put up another turbine, but that's the question that Renewable Energy World is asking. Their answer?
When we heard that Mitsubishi and the Tokyo Institute of Technology (TIoT) were working on a way to use power generated while a windmill spins at night, it got us thinking. What's so special about wind power produced overnight?
The idea for TAK Studio's Turbine Lights works like this: cars drive by on the highway, creating wind that spins the turbines built onto the streetlights. The turbine then turn and generate electricity, which powers the streetlights at night or, we hope, gets fed into the grid. It's a good idea, and one of the finalists for the Greener Gadgets Conference taking place later this month in New York City. There's just one issue: this isn't a new idea at all.
Not only has a name been decided on – the Nemesis – but Ecotricity founder Dale Vince's pet electric car project is now sitting in Vince's driveway. Well, it is when he's not out driving it.

Chrysler may be slow to the party in introducing production hybrids and electric vehicles, but that doesn't mean they haven't been working on cleaner energy. The company has been cooperating with university researchers on growing biofuel feed stocks on brownfield sites, for example. They have also been growing potential biofuel crops at their Chelsea, MI proving ground as an alternative to grass. The company's latest effort is a wind power project, also at the Chelsea track.
I think we have a winner for the greenest car at the 2007 Tokyo Motor Show. Below the fold is a video all about the Mitsubishi iMiEV Sport concept. It's a plug-in electric car with a cool tear drop shape and a number of cool ways of charging the batteries. The iMiEV's lithium-ion batteries can be charged via a wireless microwave charger in your garage floor which means you don't have to struggle to plug it in.
The prospect of wind power is highly appealing as a source of clean renewable energy. A lot of people would love to be able to stick a wind mill in the yard for some extra juice. The problem is that traditional wind turbines are large and some of them may be dangerous to birds. Mariah Power has devised one that takes up very little real estate and shouldn't pose a hazard. The thirty foot tall WindSpire is only two feet wide and generates 1 kW. It works in winds of 8mph and up and can generate 19
Of course, train travel has the potential to be one of the greenest forms of travel around. And, the best part of it all is that the more people on the train, the better! What I mean is that the emissions of the train can be spread over a larger number of people - people who might otherwise be driving.
