Thermoelectric generator pulls energy from room temperature heat

Scientists in Japan have developed a new organic device that can harvest energy from heat. Unlike other thermoelectric generators, this one works at room temperature without a heat gradient.Continue ReadingCategory: Energy, TechnologyTags: Energy, Ther… Continue reading Thermoelectric generator pulls energy from room temperature heat

Supercritical geothermal power: Limitless promise or impossible dream?

Supercritical geothermal power holds the promise of meeting humanity’s energy needs for millions of years, but how practical is it? A new analysis by Karthik Subramanian of Lux Research suggests that it may lie somewhere between improbable and impossib… Continue reading Supercritical geothermal power: Limitless promise or impossible dream?

HotTwist water-based thermal system cuts heating bills by 75%

Water can hold a huge amount of thermal energy, and a new system to tap into this resource is being trialed in Scotland. A startup called SeaWarm uses heat stored in bodies of water for buildings, pulling four times more heat out than electricity used….
