Hot stuff: New approach could double geothermal heat extraction efficiency
From Penn State 28/09/23 Geothermal heat offers a promising source of renewable energy with almost zero emissions, but it remains a relatively expensive option to generate electricity. A new technique proposed by Penn State scientists may help prevent “short-circuits” that can cause geothermal power plants to halt production, potentially improving the efficiency of geothermal power, […]
Clever coating turns lampshades into indoor air purifiers
From AMERICAN CHEMICAL SOCIETY 18/08/23 Indoor air pollution may have met its match. Today, scientists will report that they have designed catalyst-coated lampshades that transform indoor air pollutants into harmless compounds. The lampshades work with halogen and incandescent light bulbs, and the team is extending the technology so it will also be compatible with LEDs. […]
