Solar power researchers have traditionally only used the power measurements from single residential solar photovoltaic (PV) systems to estimate the power...

By adding utility-scale solar farms throughout New York state, summer electricity demand from conventional sources could be reduced by up to 9.6% in some places. But Cornell...

Directly converting electrical power to heat is easy; however, converting heat into electrical power is not as easy. To address this issue, a tiny silicon-based device was developed that can...

Three new unmanned helicopters were unveiled at AUVSI’s XPONENTIAL show in Chicago.

Manufacturers across medical, space, aviation, military, and automotive industries could use the technology to build complex machines that integrate with surfaces to be very compact, but can...

A heat-rejecting film was developed that could be applied to a building’s windows to reflect up to 70 percent of the Sun’s incoming heat. The film remains highly transparent...

Researchers have developed an imaging technique that uses a tiny, super sharp needle to nudge a single nanoparticle into different orientations and capture 2-D images to help...

From airplane wings, to overhead power lines, to the giant blades of wind turbines, a buildup of ice can cause problems ranging from impaired performance all the way to catastrophic...

Existing nanosensor technologies depend on an external power source (typically a battery) to operate. Chemical and biological sensors based on nanowire or nanotube technologies exhibit...

Egyptian blue, derived from calcium copper silicate, was routinely used on ancient depictions of gods and royalty. Previous studies have shown that when Egyptian blue absorbs visible light, it then...

NASA's Johnson Space Center (JSC) has been a leader in human space exploration for more than half a century. Established in 1961 in Houston, TX as the Manned Spacecraft Center, the center...

Don’t hold your breath, says Jeff Crystal from Voltaic Systems.

As Industry 4.0 initiatives bring more and more industrial axes of motion into the realm of automation, the need for cost-effective control across them grows as well. Advances in...

Today's photovoltaic power systems are generally comprised of a single photovoltaic module or multiple modules connected by combinations of series and parallel circuits as a photovoltaic array....

Ames Laboratory is a government-owned, contractor-operated national laboratory of the U.S. Department of Energy (DOE), operated by and located on the campus of Iowa State University in Ames, IA. For more than...

The grand-prize-winning nanotechnology coating imparts anti-reflection and water-repellency capabilities to surfaces made of silicon, glass ,and some plastics, including Teflon.

A team of semiconductor researchers based in France has used a boron nitride separation layer to grow indium gallium nitride (InGaN) solar cells that were then...

New solar energy research from Arizona State University demonstrates that silicon-based tandem photovoltaic modules, which convert sunlight to electricity with higher efficiency than...

In 1977, the National Renewable Energy Laboratory (NREL, Golden, CO) started as the Solar Energy Research Institute (SERI), spurred by national concern during the 1973 oil embargo that caused long lines...

This column presents technologies that have applications in commercial areas, possibly creating the products of tomorrow. To learn more about each technology, see the contact information provided for that...
