The main difference between lithium-ion and lithium-air batteries is that the latter replaces the traditional cathode - a key battery component involved in the flow of electric current - with air. That makes the rechargeable metal-air battery lighter with the potential to pack in more energy than its commercial counterpart.
The Institute for Advanced Sustainability Studies (IASS) together with CERN (European European Organization for Nuclear Research) reached an important milestone on February 20th with the successful testing of a prototype superconducting cable able to carry 20 kA of current.
MIT spinout XL Hybrids is upfitting (and retrofitting) gas and diesel commercial vans and trucks with fuel-saving 'add-on' electric powertrains whose batteries are charged through energy generated by braking.
The European FP7 project ArtESun aims to develop highly efficient organic solar cells with an increased lifetime and a decreased production cost. The ultimate goal of the ArtESun project is to bring organic photovoltaic technologies (OPV) towards introduction into the competitive thin-film PV market.
The German Aerospace Center is testing the performance and durability of reflectors and receivers for solar power plants in Ouarzazate, Morocco and in Bokpoort, South Africa. These quality controls are the first to permit an assessment of solar power plant component quality and longevity.
A new GBP20 million three-year programme that will support research to develop new low carbon manufacturing processes and technologies, low carbon cities and offshore renewables in the UK and China was agreed yesterday.
Researchers have developed a new technique that uses existing technology to allow researchers and natural resource managers to collect significantly more information on water quality to better inform policy decisions.
Insulation materials of tomorrow must be both efficient and environmentally friendly. Fraunhofer scientists are developing insulation foam made from wood that could re- place petrochemical plastics in the long term.
Being able to charge up to 30 electric cars at once requires some ingenious energy management. Researchers are incorporating a mix of renewables into the design of a smart grid for Germany's largest charging station.
LEDs are durable and save energy. Now researchers have found a way to make LED lamps even more compact while supplying more light than commercially available models. The key to success: transistors made of the semiconductor material gallium nitride.
Researchers at Harvard's Wyss Institute have developed a method to carry out large-scale manufacturing of everyday objects - from cell phones to food containers and toys - using a fully degradable bioplastic isolated from shrimp shells. The objects exhibit many of the same properties as those created with synthetic plastics, but without the environmental threat.
The Energy Department's National Renewable Energy Laboratory (NREL) has published a report that aligns solar policy and market success with state demographics. By organizing the 48 contiguous states into four peer groups based on shared non-policy characteristics, the NREL research team was able to contextualize the impact of various solar policies on photovoltaic installations.
Lab success doesn't always translate to real-world success. A team of Michigan State University scientists, however, has invented a new technology that increases the odds of helping algae-based biofuels cross that gap and come closer to reality.
