Re: Heat engines
"So a 300MWe plant will be rejecting nearly 600MW of heat per hour.... Laws of Thermodynamics can't be beat..."
The trick is to find uses for the "waste" heat - hence the push for district heating (and cooling!(*)) systems driven from them.(**)
(*) https://entropyproduction.blogspot.co.uk/2005/10/solar-thermal-cooling.html - yes it says solar but any suitable heat source will do. Solarfrost.com have been working on these kinds of systems for 20 years.
(**) In some countries the district heating is used to warm greenhouses and extend the growing season as well as defrost critical roads. It's not just something for housing.
