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

Typical direct-injection engines, such as diesel engines, can produce soot due to fuel-rich combustion conditions. Filters and catalytic converters are currently used to reduce soot and harmful...

NASA's Glenn Research Center has developed a novel solid oxide fuel cell (SOFC) with five times the specific power density of currently available SOFCs. This highly efficient SOFC can operate on a...

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....

The Create the Future Design Contest was launched in 2002 to help stimulate and reward engineering innovation. In the past 16 years, the annual contest has drawn more than 13,000 product...

Yokogawa Corporation of America, Newnan, GA, released the WT5000 power analyzer that achieves accuracy of ±0.03% at 50/60 Hz, allowing precision evaluation of power consumption, loss, and efficiency of...

Professor Hart spoke with Tech Briefs about why his team's new battery may someday find its way beyond niche applications and into electric vehicles.

In the quest for abundant, renewable alternatives to fossil fuels, scientists have sought to harvest the sun’s energy through “water splitting,” an artificial photosynthesis technique...

Internet of Things (IoT) applications — whether for city infrastructures, factories, or wearable devices — use large arrays of sensors collecting data for transmission over the Internet to a central,...

Eagles can store energy in their feet without having to continuously contract their muscles to then jump high or hold on to prey. New materials have been created that can store energy this way. The...

In order to make ultrafast pulses accessible to the broadest possible field of applications, Coherent has been implementing a comprehensive program of design methodologies, materials...

ALUMINUM-POWERED ELECTRICITY GENERATION

Aluminum has an incredibly high energy density — double that of gasoline and an order of magnitude greater than...

Have you heard of "fatbergs?" Researcher Asha Srinivasan explains how her team is turning masses of fat, oil, and grease into biofuel.

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

In 1951, the first nuclear reactor in Idaho was built, starting a legacy at what is now Idaho National Laboratory (INL). INL is the site where 52 pioneering nuclear reactors were designed and...

When hit with light, semiconductors (materials that have an electrical resistance in between that of metals and insulators) generate an electric current....

Additive manufacturing (3D printing) can be used to manufacture porous electrodes for lithium-ion batteries, but because of the nature of the manufacturing process, the design of these...

Researchers discovered that an on-and-off kind of thermal regulation is possible if you look to the squid.

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...

Hybrid solutions that combine small photovoltaic (PV) panels with industrial grade rechargeable Lithium-ion (Li-ion) batteries provide long-term power for remote...

Lithium-metal batteries — which can hold up to ten times more charge than lithium-ion batteries — haven't been commercialized because of a fatal flaw: as the batteries charge and...

Photovoltaic systems are continually evolving to improve their efficiency and financial viability. One trend is to move to larger strings of cells giving higher dc voltages to be...

A small voltaic cell was developed that is sustained by the acidic fluids in the stomach. The system can generate enough power to run small sensors or drug delivery devices that can reside in the...

A new chemical composite could be used to store heat from the Sun during the day in a thermal battery, and release the heat when needed. A common approach to thermal storage is to use...

By introducing some new ingredients to the flow battery, Stanford University scientists are advancing a new way to store wind and solar electricity.

A temperature sensor was developed that runs on 113 picowatts of power — about 10 billion times smaller than a Watt. The technology could enable devices that can be powered by harvesting energy from...
