Converting More Heat To Useful Energy

An anonymous reader writes "New Scientist has an article about a technology proposed by Wow Energies which can nearly double the efficiency of power stations, utilise waste heat from many industrial processes, and reduce toxic pollution. The secret is to use propane vapour, which boils at much lower temperatures than steam, and so can convert more heat to useful energy. Even better, it uses existing pump and turbine technology. Could this be a big weapon in the fight against global warming?"

Nuclear should do even better with this

[pfdietz]

Nuclear reactors are currently even less efficient than coal-burning powerplants, and produce even more medium grade waste heat. This technology should be especially useful there. It should help fusion power even more, since the cost of a fusion core (per thermal MW) is projected to be many times that of a fission core, so getting the most power out of it will be very important.
