Heres my 2c,
The dirty old US govt are predisposed to opppose anything which is energy efficent and works because all the polititians are in the pocket of the corperations.
The continental US has almost enough oil to be self sufficient, BUT if the US stopped importing oil then the world standard dollar would shift from the greenback, to the Euro. Then the US dollar would devalue beyond belief. Then the US economy would collpase. This would in turn cause the 90% of the world econmys to fall over too.
The obcene cost of fuel is a crime. Here in NZ we are paying $2.12 per litre. Our buys about 75c US, and theres 3.6 litres to a US gallon. You do the math.
How much are you paying per gallon ATM?
