FYI, anyone contemplating getting into this stock, if you have easy access to foreign exchanges I'd recommend you trade it on the ASX (symbol EVM). Liquidity is much better there (for now anyway).
It's also unofficially traded in Germany as E8B, but also with very very low volumes.
If the decision from the SCPPA is positive, then I expect this company will generate a lot of interest, as it represents a "new" type of solar energy. I'd expect to see the concept (well, it would no longer be just a concept anymore if they get a PPA (Power Purchase Agreement) in California) covered in major media and popping-up on green-tech websites around the world.
It would be a WORLD'S FIRST for the solar tower/chimney design.
