Cleantech "Power 10" Ranking (Vol. I)

Very interesting and useful comments by contributors, especially the information on the non US wind companies.

A company I've followed for a long time and own is Energy Conversion Devices (ENER) that makes amorphous Si solar panels. They also make batteries for hybrid cars and have some interesting developments in hydrogen technology. They also have a phase change memory patent that has attracted some developmental interest from major semiconductor companies. It could become a major addition to revenues if it works out.
