Isn't this true of all "green technologies" though?
There are some interesting Hydrogen extraction techniques being researched, but anything based on electricity, right now is a total farce.
Bio mass fuels do truly have green credentials, but our government limits their production to some measly percentage figure of our annual use of petrol/diesel, no doubt because the oil companies have them bent backwards.
A sad situation when corporations and profits are far more important than actually doing something constructive. All token gestures atm I'm afraid, and us sheep have little choice but to follow.
