My ideal plan would be to add that tax, and have the funds from that tax go specifically for green-energy research.
Unfortunately with our current politians, I ain't holding my breath.
fuck research, just put in a light rail and double the gas tax. fewer people drive. slowly make it more unafordable to drive. that is as green as it gets. research doesn't mean shit unless it is practical. i see all this theoretical bullshit out there. lets do something real like make it cost $$$ to pollute. big business, big cars and the like. dont need research to do that.
