Re; cheap power
Quite a few other people, want to want to be driving things apart from electric cars when oil runs out. All the oil companies are putting lots of money into 'Alternative fuels'. what most people forget is that I.C. engines first of all ran on ethanol. Historically Gasoline is the Alternative, even all Henry Ford's Cars until the model A ran on undiluted Moonshine, had Oil not been found in Pennsylvania they still would. Gasoline for cars is no longer a few cents a gallon. Research groups all over the States are looking at liquid fuels that can be used in car engines without much expensive modification. Modern cars have injection systems and an ECU that can adjust the timing widely the new V6 Ecoboost Ford engine should do good mileage on E85 while doing good power.
