Thermoelectrics: Converting Waste Heat to Power?

NASA has used thermoelectric energy, or the conversion of waste heat to electricity, for decades to power spacecraft and the Mars Science Laboratory Rover. However, thermoelectric energy has attracted minimal attention in the alternative-energy world due to its limited commercial viability, until recently. Last year, Michigan State University (MSU) with the support of the Lawrence Berkley National Lab developed a new class of thermoelectrics using a compound called tetrahedrite that is believed to be more cost-effective and has the potential for everyday use. One start-up finding success building on the findings from MSU is Alphabet Energy. They have developed a stand-alone… [more]
