Most of today's batteries are made up of rare lithium mined from the mountains of South America. If the world depletes this source, then battery production could stagnate.
(Phys.org) —Harvesting waste heat from power stations and even vehicle exhaust pipes could soon provide a valuable supply of electricity.
An immensely powerful yet invisible force pulls water from the earth to the top of the tallest redwood and delivers snow to the tops of the Himalayas. Yet despite the power of evaporating water, its potential to propel self-sufficient ...
University of California, Irvine researchers have invented nanowire-based battery material that can be recharged hundreds of thousands of times, moving us closer to a battery that would never require replacement. The breakthrough ...
If Germany has taken a pioneering though risky role in shifting to renewable energy, then the tiny village of Feldheim—population 150—is at its vanguard.
It's named after a Nordic god and drills deep into the heart of a volcano: "Thor" is a rig that symbolises Iceland's leading-edge efforts to produce powerful clean energy.
A unique thermosolar power station in southern Spain can shrug off cloudy days: energy stored when the sun shines lets it produce electricity even during the night.
Researchers have reached a critical milestone in solar cell fabrication, helping pave the way for solar energy to directly compete with electricity generated by conventional energy sources.
An Israeli firm says a super-efficient engine it has created could drastically reduce fuel consumption and help power an auto industry revolution as manufacturers search for environmentally sound alternatives.
