Fuel Cell Treats Wastewater and Harvests EnergyKatherine Tweed
"In a search for solutions, we looked to soil microbial fuel cells, which use special microbes to break down soil and use that low amount of energy to power sensors. As long as there is organic carbon in the soil for the microbes to break down, the fuel cell can potentially last foreve...
The team says that the device has a wind-to-energy conversion efficiency of 3.23 percent. That’s higher than other devices that scavenge energy from the wind, but it’s a far cry short of more dedicated wind energy harvesters. For example, although it’s not an apples-to-apples compariso...
After agriculture, wood harvest is the human activity that has most reduced the storage of carbon in vegetation and soils1,2. Although felled wood releases carbon to the atmosphere in various steps, the fact that growing trees absorb carbon has led to different carbon-accounting approaches for wo...
The next steps for the researchers are to examine how they can improve the fabric's durability and ensure that its electronic parts are protected from the elements and moisture. The research was published in the journal,Nature Energy. Source:Georgia Institute of Technology...
Our company is located in an important energy and chemical industry base in China, with rich resources and convenient transportation. It is committed to becoming one of the leading chemical industry groups in China and the world. It integrates production, scientific research and sales, and ...
(Supplementary Data2). On the basis of the minimum dietary energy requirement (MDER), we find that countries with reported undernourished populations will have a shortfall of ~675.4 trillion kcal per year to nourish the increased population and the expected undernourished from their extra harvested ...
UNIVERSITY PARK, Pa., May 5, 2009 – The structure of chlorophyll molecules in green bacteria that are responsible for harvesting light energy have been determined by a team of international scientists. This discovery could one day be used to build artificial photosynthetic systems, like those that...
much higher levels - 100 percent humidity for fog-harvesting methods, and above 50 percent for dew-harvesting refrigeration-based systems, which also require large amounts of energy for cooling. So the new system could potentially fill an unmet need for water even in the world's driest regions...
A new type of hybrid solar energy converter can use energy from the Sun to create both electricity and steam. The device reportedly has high efficiency and runs at low cost, allowing industry to make use of a wider spectrum of solar energy.
