Build Your Own Electric Vehicle

The advantages of electric vehicles (EVs) are well-known: nonpolluting operation, a renewable power source, safety, and low cost of operation. The disadvantages include limitations on speed, operating range, and convenience as well as the high cost of converting existing vehicles to electric operation; while acknowledging such other disadvantages as lack of effective heating, air conditioning, and power steering, EV advocate Brant says some of the best-known ones are myths. Speed, for instance, is related to body weight, and less weight means more speed. (Weight is, however, also a factor in safety: lighter weight often means less safety, especially in collisions, and Brant doesn't mention the collision factor.) Brant provides comprehensive instruction in converting a vehicle to electric power. It is not for the casual hobbyist, though, as is evident in such features as formulas for divining the potential top-end speeds of specific EVs--a precise system to answer questions of speed, but hardly the simple ballpark figure casual readers interested in exploring EVs' possibilities might want.
