I am tending to prefer "biofuels"...
Not the ones which use "food" stock (ie. ethanol from corn), the ones that use biomass waste,
(or from algee).
I also just found this site tonight and signed up for thier free newsletter, will see what they have/say -
http://www.greenchipstocks.com/
Keep finding news articles on bunches of companies, but cannot find symbols, so theres alot of
them out there that have not gone public yet.
