HC Deb 24 November 1969 vol 792 c19W
78. Mr Dalyell

asked the Minister of Technology what work he is supporting on the development of electric or steam cars.

Dr. Ernest Davies

The main problem of the electric car is the battery. The Department is therefore supporting work aimed at the development of batteries with high energy storage capacity. The Department is also studying the application of the steam engine to automobiles, but the indications are that problems associated with development of a useful engine are considerable.
