This is at some sort of auto show or new technology show, I think in Japan. This car is powered solely by hamsters on wheels. I imagine it stores the power they generate, or amplifies it somehow. But you know someone had to come up with the idea at some point... it was just a matter of time.
And when you think about it, that makes this car the least environmentally-friendly car in the world. Think about it: its fuel isn't hamsters, its fuel is hamster food. Its fuel is seeds, and its waste by-product is hamster shit. You think smog is a problem, wait until you see what it's like when your car leaves little droppings everywhere it goes.
And if you leave the car out overnight in cold climates, its engine goes into hibernation. (Hamsters will drop into hibernation almost automatically if the air temperature falls below about 40 F.) Brings a whole new meaning to "warming up the car".
