The end of the oil era has been predicted for some time, and with a barrel of oil now costing more than $70 (as of 20 April, 2006), the crunch appears to be here.  The issue seems to be when the crisis will occur, not if the crisis will occur.  Consider this quote from www.lifeaftertheoilcrash.net:  

"Civilization as we know it is coming to an end soon. This is not the wacky proclamation of a doomsday cult, apocalypse bible prophecy sect, or conspiracy theory society. Rather, it is the scientific conclusion of the best paid, most widely-respected geologists, physicists, and investment bankers in the world. These are rational, professional, conservative individuals who are absolutely terrified by a phenomenon known as global 'Peak Oil.'"

Whether you endorse this point of view, or simply don't like the idea of paying $3 or $6 or $10 for a gallon of gasoline, the Wheel from RevoPower can help you, and thus help the world.  With 200+ miles per gallon and the ability to pedal without using the engine at all, we the people now have an affordable way to beat the price at the pump.
