Abstract
Coal, either as coal fines or as coal briquettes, is introduced into a coking chamber and is thereat exposed to microwave radiation to transform the coal into hot coke. Preferably, the microwave radiation is at a frequency of from twenty to 3000 MHz. The hot coke is then passed to a cooling zone whereat photocells absorb radiant energy from the hot coke and transform the thus absorbed radiant energy into electricity.
