From GRAEME BUSHELL
The waste heat generated by a 250 cc engine is more than adequate for
the purpose. Since internal combustion engines are generally somewhat less
than 50 per cent efficient, this means that around 10 kilowatts of waste
power is available for heating, much more than you get from your average
domestic electric heater. In conventional cars only a small proportion of
the waste heat is used for cabin heating, the bulk being removed via the
radiator.
