How Ekotrope Software Will Impact Construction

The average U.S. residential utility customer consumed 940 kilowatt-hours per month in 2011, equivalent to 11,280 kWh a year, according to the U.S. Energy Administration. Average annual consumption ranged from 6,252 kWh in Maine to 16,176 kWh in Louisiana. This translated into monthly bills ranging from $80.09 in Maine to $142.41 in Alabama and $202.72 in Hawaii, for a national average of $110.14 a month...

Paper-like material powers devices with a simple touch

Tapping or rubbing a paper-like material developed by Disney Research can generate enough energy to light a string of light emitting diodes or an e-paper display. Researchers at Disney Research in Pittsburg and the Carnegie Mellon University have demonstrated simple flexible generators made of paper-thin sheets of plastic and other everyday material that harvest kinetic energy. The design of the Paper Gene...

Unique wind power generator gets support from crowd funding site

A unique wind power generator is getting support from an international crowd funding body. The ring-type wind power generator, which was developed by Tokio Fukui, can generate five times as much power compared to a wind turbine with the same bore diameter. The wind power generator is lightweight and has no shafts or any exterior parts, and only needs a 2-square-meter area to be installed in – it is...

Jumping water droplets carry electrical charge – M.I.T.

Water droplets are taking a “jump” towards becoming the newest source of energy. Researchers at the Massachusetts Institute of Technology have found that, under certain circumstances, tiny water droplets can carry an electric charge. They believe that this finding could lead to more efficient power plants as well as a new way of creating power. According to M.I.T. postdoc Nenad Miljkovic, under certain...

New pathway can increase biofuel yields by 50 percent

A new synthetic metabolic pathway developed by chemical engineering researchers at the University of California, Los Angeles, can break down sugars quickly and efficiently. The researchers believe that the rate in which this new pathway allows for the breakdown of glucose could lead to a 50 percent increase in the production of biofuels. The new pathway is intended to replace the natural metabolic...

From trash to treasure: plastic bags to high-tech nanomaterial

Researchers from the University of Adelaide have developed a process of turning waste non-biodegradable plastic bags into high-tech nanomaterial. The process that the researchers have developed makes use of non-biodegradable plastic grocery bags to create “carbon nanotube membranes,” which are highly sophisticated and expensive materials with a variety of potential advanced applications includ...

Sugar cane ash used for better, greener cement

Cement made from waste ash from sugar production is not only stronger than ordinary cement, it is also a greener building material. Researchers at the Niels Bohr Institute at the University of Copenhagen have found that cement made with an amount of sugar cane ash mixed in are stronger, can withstand higher pressure and crumble less than ordinary cement.In countries where sugar cane...

New family of materials for water-splitting found by M.I.T.

Researchers at the Massachusetts Institute of Technology have found a new family of materials that can easily trigger oxygen evolution, a key reaction in fuel cells, lithium-air batteries and other advanced energy storage and delivery systems. Double perovskites are a variant of mineral that exists in abundance in the Earth’s crust. Yang Shao-Horn, the Gail E. Kendall Professor of Mechanical...

Copper and ammonia key to new catalyst to clean vehicle emissions

The newest models of diesel engines emit very little of the greenhouse gas nitric oxide due to the use of the latest catalytic converters. A team of researchers at the Institute for Integrated Catalysis at the United States Department of Energy’s Pacific Northwest National Laboratory have completed a study on zeolite-based catalysts used in Europe. These zeolite-based catalysts blast away the pollu...

Waste eating bacteria used to produce electricity

Researchers at Stanford University have invented a microbial battery that can generate electricity from sewage. The battery uses microbes that can produce electricity as they digest plant and animal waste as mini power plants. Yi Cui, a materials scientist, Craig Criddle, an environmental engineer, and Xing Xie, an interdisciplinary fellow, developed the microbial battery. The microbes used...
