I'm doing some research on the fuel cell industry, worldwide and in
North America. However, I'm having trouble finding the following on
google properly. I'm wondering if someone can provide me the street
info on the following:

1. union involvement in the industry
2. economic factors influencing the industry
3. political factors influencing the industry
4. government involvement and control of the industry
5. hiring trend and long term prospects
6. environmental issues (although this is not hard to find)

Thanks!
