Promising New Renewable Energy Technologies

I volunteer to answer questions regarding clean energy on Quora.com. Here, Tobi Ogunnaike writes: What are the most promising startups or companies pursuing innovative approaches to renewable energy generation?

You happen to be talking to the right guy. For the last 7 years, my work has been focused on reviewing literally thousands of cleantech business plans, to winnow out the few that make the most sense. If you go to 2GreenEnergy.com/investors, you will see a short summary of each of the couple dozen such concepts that I hold in high regard. Hope that helps.
