OK, you might have to be a serious EcoGeek to spend hours with this Google Maps powered clean-technology start-up map. But even for people who are just slightly curious, it should be fun.
Earth2Tech created the map which features all the major clean-tech start-up sectors. Electric vehicles, solar, lighting, biofuels, and even bioplastics are marked here.
Obvious take-away: San Francisco and Los Angeles are the places to be for everything clean-tech.
But the detail is where the real meat lies. Click on any of the icons, and you can find out more about the company and see links to recent news on the companies.
Welcome to the beginning of the clean-tech boom! Earth2Tech is going to have its work cut out for it just keeping this thing up-to-date. And that's good news for all of us.
