Improving batteries' energy storage
MIT researchers have found a way to improve the energy density of a type of battery known as lithium-air (or lithium-oxygen) batteries, producing a device that could potentially pack several times more energy ...
Cosmologists tend not to get all that excited about the universe being 74% dark energy and 26% conventional energy and matter (albeit most of the matter is dark and mysterious as well). Instead they get excited ...
Building a better battery
A new battery technology provides double the energy storage at lower cost than the batteries that are used in handheld electronics, electric vehicles, aerospace and defence.
$25,000, 350-mile-per-charge electric car could be reality by 2017, DOE says
In an event flanked with all the electric cars that have recently come to market, and a handful of those that are poised for sale later this year, U.S. Energy Secretary Steven Chu and L.A. Mayor Antonio Villaraigosa flipped ...
Thin, flexible glass for energy storage
A new use for glass is being developed by researchers in Penn State's Materials Research Institute that could make future hybrid-electric and plug-in electric vehicles more affordable and reliable.
Astrophysicists cast doubt on link between excess positrons and dark matter
(PhysOrg.com) -- Astrophysicists are looking everywhere - inside the Large Hadron Collider, in deep mines and far out into space - for evidence of dark matter, which makes up about 25 percent of the energy density of the ...
New material possible boon for lithium ion batteries
Batteries could get a boost from an Oak Ridge National Laboratory discovery that increases power, energy density and safety while dramatically reducing charge time.
Springs built from nanotubes could provide big power storage potential
(PhysOrg.com) -- New research by MIT scientists suggests that carbon nanotubes -- tube-shaped molecules of pure carbon -- could be formed into tiny springs capable of storing as much energy, pound for pound, ...
Cassini Data Help Redraw Shape of Solar System (w/ Video)
(PhysOrg.com) -- Images from the Ion and Neutral Camera on NASA's Cassini spacecraft suggest that the heliosphere, the region of the sun's influence, may not have the comet-like shape predicted by existing ...
