This report considers four new methods of energy conversion, namely: a) Fuel cells; b) Thermoelectric generators; c) Thermionic generation; d) Magnetoplasmadynamic generation. After a brief survey of the principles and of the present state of development their suitability to railway application is examined. Of the four methods only fuel cells and thermoelectric generators appear to have any future for railways. At the present time development of fuel cells is not sufficiently advanced for widespread practical application, but it is hoped that in 5 - 10 years the techniques will have developed sufficiently to make them of use. Thermoelectric generators are already available for power outputs up to 100 watts and although the price is at present high with further development and quantity production there is every hope that the first cost will in due course be halved. It is unlikely however that these generators will ever by economic for power outputs greater than 1 kW.
