A pickup truck with one to three giant hamster wheel generators in the back. The people in the back run to provide power while the driver drives. The motor is electric and coupled directly to the "power supply." Add a battery, regenerative braking, etc. if any real acceleration is needed. It may or may not be faster than running, but definitely safer in traffic.
Exercise for the people in the back and amusement for all concerned...-- cowtamer, Nov 05 2010 cute!-- blissmiss, Nov 05 2010 random, halfbakery
