Solar-powered electrochemical cell used to produce formic acid from CO2

By - July 2, 2014 1 Picture
Rising atmospheric CO2 levels can generally be tackled in three ways: developing alternative energy sources with lower emissions; carbon capture and storage (CCS); and capturing carbon and repurposing it. Researchers at Princeton University are claiming to have developed a technique that ticks two of these three boxes by using solar power to convert CO2 into formic acid. Read More

Fraunhofer developing fuel cell system to power the home

By - June 4, 2014 1 Picture
As the world shifts to alternative forms of energy, ways to make homes less dependent on the grid continue to gather steam. Fuel cells, which are more efficient and have lower emissions than internal combustion engines seem like a logical candidate for taking up the slack, so the Fraunhofer Institute for Ceramic Technologies and Systems (IKTS) in Dresden is partnering with the heater manufacturer Vaillant to develop a domestic fuel cell system that uses natural gas to produce both heating and electricity.

Screwy-looking wind turbine makes little noise and a big claim

By - May 27, 2014 3 Pictures
Although it's getting increasingly common to see solar panels on the roofs of homes, household wind turbines are still a fairly rare sight. If Rotterdam-based tech firm The Archimedes has its way, however, that will soon change. Today the company officially introduced its Liam F1 Urban Wind Turbine, which is said to have an energy yield that is "80 percent of the maximum that is theoretically feasible." That's quite the assertion, given that most conventional wind turbines average around 25 to 50 percent. Read More

Altaeros set to break world record with 1,000 foot-high floating wind turbine

By - April 6, 2014 14 Pictures
Winds are stronger and steadier at higher altitudes, that’s why the Buoyant Air Turbine (BAT) from Altaeros is pushing to be the highest wind turbine in history. Already tested to 500 feet off the ground in 45 mph winds, this helium-filled shell with a wind turbine in the middle is soon shooting for a world record 1,000 ft float. Packing down into a shipping container for transport, the BAT is being proposed as a quickly deployable tethered power source for remote areas and emergency zones. Read More

Bacteria brews biofuel with potential to replace high-energy rocket fuel

By - April 1, 2014 2 Pictures
Researchers at the Georgia Institute of Technology and the US Department of Energy’s Joint BioEnergy Institute have engineered a bacterium that could yield a new source of high-energy hydrocarbon fuel for rocketry and other aerospace uses. High-energy, specific-use hydrocarbon fuels such as JP-10 can be extracted from oil, along with more commonly used petroleum fuels, but supplies are limited and prices are high – approaching US$7 per liter. That’s where the new bacterium, engineered by Georgia Tech scientists Stephen Sarria and Pamela Peralta-Yahya, could come in. Read More

Solar-panel skin could make Dutch homes energy neutral

By - March 5, 2014 8 Pictures
Around 60 percent of the homes in the Netherlands are row house terraces, with around a quarter of those built in the post-war period. While these constructions characterize much of the Dutch urban landscape, they weren't exactly built with energy efficiency as their first priority. A team of Delft University students has developed a concept for a solar-powered skin designed to optimize energy usage, while also preserving this classic Dutch architecture. Read More

Researcher looks into wastewater zooplankton as biofuel feedstock

By - February 5, 2014 1 Picture
With dwindling non-renewable fuel sources creating an enormous energy challenge, the search is on to develop sustainable, renewable types of energy such as solar, wind and biofuel. One of the recent developments in this field comes from New York's Clarkson University, where new findings suggest that small organisms found in wastewater treatment lagoons could be used as biofuel feedstock.
