Using Waste Heat

[John Coviello]

There are a number of companies working on ways to use waste heat from both power generation and industrial processes to generate power.  Some of these schemes propose to increase gas and coal generating efficiencies above 50%, from current efficiencies around 35%.  These technologies run waste heat through a secondary generation loop using lower boiling point liquids to drive trubines to generate electricity.  Ramping up this technology and using it with new ethanol plants would reduce our need for new power plants of all kinds.
