Capturing wasted electricity with triboelectric generators
(Phys.org) —With one stomp of his foot, Zhong Lin Wang illuminates a thousand LED bulbs – with no batteries or power cord. The current comes from essentially the same source as that tiny spark that jumps ...
Energy supply from hydropower projects depends on rainforest conservation
Research published in the Proceedings of the National Academy of Sciences shows that conserving rainforests in the Amazon River Basin will increase the amount of electricity that hydropower projects in the area can produc ...
A storage power plant on the seabed
Norwegian research scientists will contribute to realising the concept of storing electricity at the bottom of the sea. The energy will be stored with the help of high water pressure.
Techniques for the manipulation of matter at the nano scale: New insights on 3-D printing
(Phys.org)—Techniques for the manipulation of matter at the nano scale are a step further ahead with the publication of new results from a UTS research group.
Fully renewable electricity could be competitive
(Phys.org) —A carbon price of between $50 and $100 per tonne of carbon dioxide would make coal-fired and gas-fired power less economical than renewable electricity, a UNSW study shows.
US carbon emissions in surprise drop
US emissions of carbon dioxide blamed for climate change fell in 2011 and have slipped to a 20-year low this year as the the world's largest economy uses more natural gas and less coal, data shows.
First ever hybrid solar-coal power plant operating
Report firms up land-use requirements of solar: 1,000 homes would require 32 acres
The Energy Department's National Renewable Energy Laboratory (NREL) has published a report on the land use requirements of solar power plants based on actual land-use practices from existing solar facilities.
UT biosolar breakthrough promises cheap, easy green electricity
Barry D. Bruce, professor of biochemistry, cellular and molecular biology, at the University of Tennessee, Knoxville, is turning the term "power plant" on its head. The biochemist and a team of researchers have developed ...
Battery and memory device in one: Future nanoelectronic information storage devices are also tiny batteries
(Phys.org) —Resistive memory cells (ReRAM) are regarded as a promising solution for future generations of computer memories. They will dramatically reduce the energy consumption of modern IT systems while ...
Japan 'plans solar panels for all new buildings'
Japan is considering a plan that would make it compulsory for all new buildings and houses to come fitted with solar panels by 2030, a business daily said Sunday.
Americans use more efficient and renewable energy technologies
(Phys.org)—Americans used less energy in 2011 than in the previous year due mainly to a shift to higher-efficiency energy technologies in the transportation and residential sectors. Meanwhile, less coal ...
