“Many of the patients are children who live with pacemakers for many years” An experimental device converted energy from a beating heart to provide enough electricity to power a pacemaker , in a study presented [...]

The potential payoff is the ability to produce JP-5 fuel stock at sea Refueling U.S. Navy vessels, at sea and underway, is a costly endeavor in terms of logistics, time, fiscal constraints and threats to [...]

Approximately 90 percent of the world’s electricity is generated by heat energy. Unfortunately, electricity generation systems operate at around 30 to 40 percent efficiency, meaning around two thirds of the energy input is lost as [...]

Allows the smaller fish to escape. The invention, named Safetynet, was invented by Dan Watson, a former student at Glasgow School of Art and helps guide juvenile fish inadvertently caught in the nets to safety. [...]

A new type of power cell can convert mechanical energy—from walking, for example—to chemical energy and store the power until it is released as electrical current. The power cell generates enough current to run a [...]

Sun-powered system developed by MIT students could provide electricity, heat and cooling to rural schools and clinics. In some isolated clinics in parts of Africa, the electricity needed to power lights and medical devices is [...]

“We have developed a material that absorbs infrared and is all transparent to the visible light.” One of the holy grails of solar cell technology may have been found, with researchers at UCLA announcing they have created [...]

System developed at MIT could combine power harvested from light, heat and vibrations to run monitoring systems. Researchers at MIT have taken a significant step toward battery-free monitoring systems — which could ultimately be used [...]

bSolar claims up to 30 percent higher energy yields in more typical installations Israeli photovoltaics developer bSolar has developed a double-sided solar cell it claims can boost the energy yields of solar panels by up [...]

Devices a thousand times smaller than those of today’s microtechnologies could be mass-produced Scientists with the Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley have directed the first self-assembly of [...]

Sidewalk paving stones that double as WiFi hotspots It seems that a lot of people have been talking about putting things in the road lately. Just within the past few years, we’ve heard about asphalt-embedded [...]

Could potentially be applied on a mass scale Researchers at Purdue University in the U.S. have developed a new method of harvesting vast amounts of energy from waste heat. Using glass fibers dipped in a [...]
