The combination of a coal fired magnetohydrodynamic generator and a conventional steam-driven turbo-generator promises greater efficiency, cheaper electricity and lower environmental pollution than conventional power stations. Until recently, the unacceptably short lifetime of the anode electrodes has prevented this promise being fulfilled. Based upon tests described in this paper, it is predicted that the use of platinum-clad electrodes will dramatically increase the expected generator lifetime, thus paving the way to the commercialisation of magnetohydrodynamic energy converters. Approximately 1300 hours of electrode operation has now been achieved and an extrapolation of the results suggests a lifetime of 6000 to 8000 hours.
