Breakthrough in converting heat waste to electricity: Automotive, chemical, brick and glass industries could benefit from discovery

Breakthrough in converting heat waste to electricity: Automotive, chemical, brick and glass industries could benefit from discovery: "ScienceDaily (Jan. 18, 2011) — Researchers at Northwestern University have placed nanocrystals of rock salt into lead telluride, creating a material that can harness electricity from heat-generating items such as vehicle exhaust systems, industrial processes and equipment and sun light more efficiently than scientists have seen in the past."
