US nuclear regulators greatly underestimate potential for nuclear disaster
25 May 2017 at 11:15am
The US Nuclear Regulatory Commission relied on faulty analysis to justify its refusal to adopt a critical measure for protecting Americans from nuclear-waste fires at dozens of reactor sites around the country, according to a recent article. Radioactivity from such a fire could force approximately 8 million people to relocate and result in $2 trillion in damages.
Fuel from the air technology provides a path to new business for OPEC countries
24 May 2017 at 5:46am
Pioneering technology makes OPEC countries prime regions to produce synthetic fuels. This could be a key asset in phasing out fossil fuels after the Paris Agreement, while also keeping some of the existing oil industry value chain intact.
Nanoalloys ten times as effective as pure platinum in fuel cells
24 May 2017 at 5:45am
A new type of nanocatalyst can result in the long-awaited commercial breakthrough for fuel cell cars. Research results show that it is possible to significantly reduce the need for platinum, a precious and rare metal, by creating a nanoalloy using a new production technique. The technology is also well suited for mass production.
Fueling the future
19 May 2017 at 9:40am
New research investigated the full life cycle impact of one promising 'second-generation biofuel' produced from short-rotation oak. The study found that second-generation biofuels made from managed trees and perennial grasses may provide a sustainable fuel resource.
Autonomous 'soaring with solar' concept
17 May 2017 at 7:11am
Scientists are building on the proven concept of autonomous cooperative soaring of unmanned aerial vehicles (UAVs), which enables long endurance flights of unmanned sailplanes that use the power of the Sun.
Microbial fuel cell converts methane to electricity
17 May 2017 at 6:05am
Transporting methane from gas wellheads to market provides multiple opportunities for this greenhouse gas to leak into the atmosphere. Now, an international team of researchers has taken the first step in converting methane directly to electricity using bacteria, in a way that could be done near the drilling sites.
Public divides over environmental regulation and energy policy
16 May 2017 at 11:34am
A 54 percent majority of US adults believe that 'government regulations are necessary to encourage businesses and consumers to rely more on renewable energy sources,' while 38 percent support the notion that 'the private marketplace will ensure that businesses and consumers rely more on renewable energy sources, even without government regulations,' according to a new survey.
Key differences in solar wind models
15 May 2017 at 9:59am
The challenge of predicting space weather, which can cause issues with telecommunications and other satellite operations on Earth, requires a detailed understanding of the solar wind (a stream of charged particles released from the sun) and sophisticated computer simulations. New research has found that when choosing the right model to describe the solar wind, using the one that takes longer to calculate does not make it the most accurate.
Producing fertilizer from air could be five times as efficient
15 May 2017 at 6:52am
Scientists bring the prospect of farmers producing their own fertilizer from only air closer with a revolutionary reactor that coverts nitrogen from the atmosphere into NOx, the raw material for fertilizer. The method, in theory, is up to five times as efficient as existing processes, enabling farms to have a small-scale installation without the need for a big investment.
Photovoltaics and batteries: An expensive combination
15 May 2017 at 6:26am
Solar power can cover up to 40% of the electricity needs of a typical household. Going beyond that level becomes really expensive: using batteries coupled with solar panels would be twice as expensive as using the power grid.
Data science used to better predict effect of weather and other conditions
12 May 2017 at 4:57pm
Data science has been used by researchers to determine and predict the effects of exposure to weather and other conditions on materials in solar panels. Using data science to predict the deterioration of such materials could lead to finding new ways to extend their lifetime, the researchers say.
Next-gen solar cells could be improved by atomic-scale redesign
12 May 2017 at 6:39am
Researchers have uncovered the exact mechanism that causes new solar cells to break down in air, paving the way for a solution.
Can the motion of checking your smartwatch charge it?
10 May 2017 at 10:19am
Triboelectric nanogenerators (TENGs) are small devices that convert movement into electricity, and might just be what bring us into an era of energy-harvesting clothes and implants. But could TENGs, even theoretically, give us wearable electronics powered solely by the wearer's day-to-day body motion? The short answer is yes. New research demonstrates the ability of mechanical energy produced by typical body motions to power a watch or smartphone.
Turning old coffee waste into cleaner biofuels
10 May 2017 at 8:52am
Future Americano, cappuccino and latte drinkers could help produce the raw material for a greener biofuel that would reduce our reliance on diesel from fossil fuels. Although a small number of businesses are using spent coffee grounds to make biofuels, researchers have found a way to significantly improve the efficiency of the process- vastly increasing biofuel from coffee's commercial competitiveness.
Power plants could cut a third of their emissions by using solar energy
9 May 2017 at 5:38am
The COMBO-CFB project has developed a new innovative concept to increase solar energy production in the energy system. According to this research, the concept can reduce fuel consumption and emissions stressing the climate by more than 33 per cent. The concept is based on the combination of concentrated solar power (CSP) technology and a traditional power plant process into a hybrid plant which produces electricity on the basis of consumption.
