The product of the reaction is again water. This principle makes it a [[Perpetual Motion|perpetual motion]] device. With alkali metals (sodium), hydrogen may be won from water: Unfortunately, this would not only set free hydrogen; but oxygen will be bound to the metal and cannot be used. During operation, the metal hydrid will be used up and serve as the actual energy source. It has to be created by using energy. The car therefore is not powered by some miraculous energy from water, it is powered by a primary battery.<ref>http://www.inteldaily.com/?c=120&a=7157</ref> Professional journals like ''Popular Mechanics'' commented upon the alleged miracle car with "rubbish"<ref>http://www.popularmechanics.com/automotive/new_cars/4271579.html</ref>, while scientific circles ignored it.
