What are some small/micro cap stocks that are peaking your interest? And why?

Also, what sector do believe is most likely to have a big impact on the US economy in the next 30 years? I'm thinking about buying FSLEX because I believe renewable energy could be a lucrative investment.

However, I would like to know your thoughts about some individual stocks that might be overlooked. All I'm buying are indexes for now, but if you have some outside-of-the-box ideas I would like to hear it.
