Thermoelectric power may become more feasible with new material

Thermoelectric power essentially turns heat into electric power, a source which is as yet highly infeasible. While we generate a lot of heat through vehicles and in factories, even the best thermoelectric equipment can actually convert only a fraction of it. However, researchers have been able to create a new material from lead telluride which, they believe, can significantly improve the effectiveness of thermoelectric power generation.
The best thing about this material is that it isn't prohibitively expensive and thus, can be used to create more viable and efficient thermoelectric systems.
