Researchers improve efficiency of human walking (w/ video) (Update)
Humans have evolved to be incredibly efficient at walking. In fact, simulations of human locomotion show that walking on level ground and at a steady speed should theoretically require no power input at all.
An efficient path from carbon to renewable fuel production
Earth-abundant materials based primarily on carbon, nitrogen and transition metal oxides can be combined into highly efficient energy conversion devices. These devices can be used in fuel cells as well as ...
Latin America divided between oil and green energy
Latin America spends billions of dollars subsidizing fossil fuels each year, but also has some of the world's largest renewable power programs, highlighting the energy-hungry region's divisions as it charts ...
Green energy investments worldwide surge 17 percent to $270 billion in 2014
Global investments in renewable energy rebounded strongly last year, registering a solid 17% increase after two years of declines and brushing aside the challenge from sharply lower crude oil prices.
Saving energy with smart facades
Glass-fronted office buildings are some of the biggest energy consumers, and regulating their temperature is a big job. Now a façade element developed by Fraunhofer researchers and designers for glass fronts ...
Adding renewable energy to power grid requires flexibility
Solar panels, wind turbines, electric vehicles and other green power sources are proliferating rapidly, but their reliable integration into the existing electric grid is another story.
Renewable energy investment heats up worldwide
From China to Mexico, renewable energy investments are hot.
Femto-snapshots of reaction kinetics: Bonding behavior of iron pentacarbonyl experimentally decoded
Using quantum chemical calculations, they were successful in interpreting the data and obtaining a detailed picture of the intermediates and reaction kinetics. The work, which has now been published in Nature, could ...
Colliding helium and carbon monoxide particles don't have to drift apart
In a paper published on 24 March in Nature Chemistry, researchers from Nijmegen and Bordeaux showed under which special conditions carbon monoxide molecules and helium atoms do not fly apart immediately follow ...
Modeling platform shows environmental impact of retrofitted buildings
A new modelling platform can create scenarios designed to show the environmental impact of retrofitted buildings. It also helps calculate the expected reductions in energy consumption and the related costs of refurbishing. ...
