Reusing waste energy with 2-D electron gas

More than 60 percent of the energy produced by fossil fuels is lost as heat. Thermoelectric energy conversion has attracted much attention as a way to convert waste heat from power plants, factories and cars into electricity. ...

Building a sustainable future: Urgent action needed

We need to act urgently to increase the energy efficiency of our buildings as the world's emerging middle classes put increasing demands on our planet's energy resources. These are the findings of a new report, published ...

Novel circuit design boosts wearable thermoelectric generators

Using flexible conducting polymers and novel circuitry patterns printed on paper, researchers have demonstrated proof-of-concept wearable thermoelectric generators that can harvest energy from body heat to power simple biosensors ...

A little tension yields enormous solar crystals

In the race to replace silicon in low-cost solar cells, semiconductors known as metal halide perovskites are favored because they can be solution-processed into thin films with excellent photovoltaic efficiency. A collaboration ...

NREL investigates coatings needed for concentrating solar power

Next-generation concentrating solar power (CSP) plants require high-temperature fluids, like molten salts, in the range of 550-750 degrees Celsius to store heat and generate electricity. At those high temperatures, however, ...
