Researchers have developed a platinum-free catalyst in cathode of hydrogen fuel cell that uses carbon, iron and cobalt. That could make the catalysts “two to three orders of magnitude cheaper,” thereby significantly reducing the cost of fuel cells.
Laser ignition systems, which are exactly what they sound like, could replace spark plugs as the primary means to ignite the fuel-air mix in engines, boosting fuel efficiency and cutting down on carbon emissions.
Startup company SiEnergy Systems has overcome a major barrier to commercializing solid-oxide fuel cells with a prototype that operates at temperatures hundreds of degrees lower than those on the market today.
One of the major barriers between solar energy and solar-derived electricity is solar cells themselves--commercial solar cells aren’t very efficient at converting sunlight to electricity, but they are the best thing we’ve got.
Their single-electron transistor is the first of its kind made entirely from oxide-based materials, an important aspect that allows it to work as a solid-state memory.
For instance, NASA plans to wrap airliners in a self-healing skin within the next 20 years, and things like flexible, self-healing concrete have already been demonstrated, albeit only in the lab.
Their DAlH2Orean remote-controlled car runs on a combination of recycled aluminum soda can tabs and sodium hydroxide, creating a zero-emissions hydrogen vehicle
In a real-life use of Schrödinger's theoretical paradoxical cat, researchers report that they were able to quickly transfer a complex set of quantum information while preserving its integrity.
Taking a page from Officer Alex Murphy, police officers in Brazil will soon be adding a layer of cyborg tech to their law enforcement toolbox via glasses rigged with facial recognition tech.
Weaving wool into Kevlar improves the energy and water absorption of the synthetic textile, potentially making bulletproof vests more comfortable and more affordable, according to researchers in Australia.
rtemis, a software program built on the back of IBM analytics software similar to that powering Watson, is being tested as a means to provide early warnings when babies in the ICU acquire hospital-borne infections.
Future cities could include pancake-shaped buildings, power plants that harvest lightning and ocean-based skyscrapers that produce potable water and clean up trash. Those are some of the visions in the 2011 eVolo Skyscraper Competition.
Wildcat Discovery Technologies, a startup in San Diego, California, has developed new materials that could boost the storage capacity of lithium-ion batteries for cars and portable electronics by more than 25 percent.
For photographers who are attached to their analog equipment but can no longer resist the pull of the digital age, RE35 proposes a solution: a digital cartridge that fits into any 35mm camera and connects to your computer via USB.
In the last century, Russia and the United States engaged competitively in both a space race and a nuclear technology race. In this century, it appears the two are considering collaborating.
...a big announcement today. Indeed, that announcement is big: about 22 stories big. SpaceX founder Elon Musk today unveiled the company’s next big thing, the Falcon Heavy rocket, a massive launch vehicle with a cargo capacity of 117,000 pounds.
Bone marrow has long been thought to have a role in repairing damaged skin, and now UK and Japanese researchers think they’ve found the key to summoning stem cells from bone marrow to the site of damaged skin:
