When is the right time? Gasoline prices were $4 and went back down. If there were promise to their devices and realistic deadlines, GM's volt might be powered by them. As it is now, the 2010 production year for the Zenn vehicles was cancelled with no anticipated startup date for production just this April.Well maybe they are trying to keep it a secret and waiting for the right time to release the information.
As of this moment, with no pre-production model, this isn't getting off the ground.
Invest your money. I hope you become rich.
