The film also features interviews with some of the engineers and technicians who led the development of modern electric vehicles and related technologies, such as Wally Rippel, Chelsea Sexton, Alec Brooks, Alan Cocconi, Paul MacCready, Stan and Iris M. Ovshinsky, and other experts such as Joseph J. Romm (author of Hell and High Water and The Hype about Hydrogen). Romm gives a presentation intended to show that the government's "hydrogen car initiative" is a bad policy choice and a distraction that is delaying the exploitation of more promising technologies, such as electric and hybrid cars which could reduce greenhouse gas emissions and increase America's energy security. Also featured in the film are spokespersons for the automakers, such as GM's Dave Barthmuss, a vocal opponent of the film and the EV1, John Wallace from Ford, and Bill Reinert from Toyota.
