But circulation in the atmosphere is like a heat engine that requires fuel to do work, just like any combustion engine or a convection engine," said research associate at the University of Toronto, Frederic Laliberte, who is also the lead author of the study.
By the year 2000, two general types will have emerged: some form of electric vehicle, either in pure or hybrid (engine/electric) form, and a heat engine, most probably with external combustion, such as the Stirling, the Warren, or the diesel.
Conversion of heat to mechanical work in the heat engine is cyclic during the development of appropriate thermodynamic processes [1-3].
Cars are driven sporadically--perhaps an hour or two a day--but it would be better to have the heat engine continuously; trains would get more output.
