Aging power plants under threat from droughts
Thermoelectric power plants provide a third of America’s electrical generation, and the combination of aging technologies, droughts, and strict environmental regulations is likely to sharply reduce the energy output. To prevent this, researchers recommend replacing the once-through cooling systems of the aging power plants with drought-resistant recirculating models. Their study countered the calls by some groups […]

Physicists develop new material that could be used for “high-efficiency, lower-cost solar cells”
Researchers have not yet solved the biggest weakness of solar panels – their inability to produce power when there is no steady source of bright light. However, they were happy to announce that they have increased the efficiency of perovskite solar cells to take advantage of the limited daylight hours. University of Toledo (UT) researcher Dr. […]

Researchers are “storing” energy using eggshells with new conductive material
The spent shells of chicken eggs might go from unwanted biowaste to a cheap, renewable, and valuable alternative material to metals in lithium-ion batteries. A German-led study reports that powdered chicken eggshells successfully store large amounts of electrical energy. Led by researchers from Karlsruhe Institute of Technology (KIT), the international team tested eggshells as a […]

3D-printed generator allows you to generate electricity from snowfall
People can now tap snowfall for electricity, thanks to triboelectric nanogenerators that collect electrical energy from innocuous activities like footsteps and raindrops. The new energy harvester, developed by the University of California, Los Angeles (UCLA), is not only inexpensive but light as well – matching the thinness and flexibility of a plastic sheet. “The device can work […]

Cars running on “clean” hydrogen one step closer – world’s fastest hydrogen sensor developed
The safe and effective use of flammable hydrogen gas as a source of energy depends on the capabilities of the sensor system. In response, Swedish researchers has come up with hydrogen sensors that run fast enough to hit the performance targets for hydrogen-powered vehicles of the future. Their optical nanosensor fits within a plastic-based capsule. […]

Swiss startup invents higher-performance electric car battery that can leave Tesla batteries in the dust
A startup in the tiny mountainous country of Switzerland promises to deliver what electric car giant Tesla Motors has failed to pull off. Its new lithium-ion battery is said to store and produce far more power for vehicles than existing designs. Swiss company Innolith claims that an electric vehicle equipped with its lithium battery would […]

Researchers successfully generate electricity from “the coldness of the universe”: New technology could complement alternative energy sources like solar power
You’ve heard of all the ways to convert light or wind or heat into usable electricity. But have you ever thought that the coldness of the universe might serve as an alternative source of clean and renewable power? Most energy production systems get their power from somewhere. Solar panels collect light while wind turbines rely […]

Scientists discover “electric” bacteria – can it lead to next-gen batteries and miniature pacemakers?
Experts know that a strange species of bacteria found in oxygen-deprived sediment and soil can generate electricity. But they only recently learned that the microorganism achieves this through a method that differs from that used by other electric bacteria. Called Geobacter sulfurreducens, the anaerobic bacteria possess a unique biological structure. This previously unidentified feature makes it possible […]

Scientists use caffeine to give solar cells a unique energy boost
Caffeine helps boost the energy levels and mood of coffee drinkers. But did you know that it could also improve the performance of a new generation of solar panels? Researchers reported that coffee’s primary stimulant increased the efficiency of perovskite photovoltaic cells, an alternative approach to solar power. When bolstered by caffeine, perovskite solar panels […]

Electricity in unlikely places: Rock surfaces throughout the planet may act as natural solar panels
Rocks might not strike you as a potential source of clean and renewable energy, much less a substitute for solar panels. But Chinese researchers found that some stones sport metallic coats that naturally convert sunlight into electricity via the same process as photosynthetic organisms. The coating contains iron and manganese, two minerals used in photovoltaic […]
