The closest thing to free energy

Jamil Shariff is one of the world’s leading researchers into the ancient technology of Stirling Engines – he reveals why they are about to undergo a revival:

Local governments in the US are starting to develop their own strategies for energy-independence, or micro-grids. One little-known technology, the Stirling Engine, is being revived because it can make use of waste heat from other energy sources.

In Helena, MT, city commissioners are designing a project to cut utility bills by generating electricity at the wastewater treatment plant, the city government’s biggest energy user. Camp, Dresser & McKee Inc. are drafting plans for a Stirling engine and generator, which will use excess methane gas at the plant to generate electricity.

The technology likely will cost several hundred thousand dollars but could pay for itself in as few as five years. So what is a Stirling engine exactly, and why are they not more widely used?
