    A spray-on battery could revolutionise technology - allowing for slimmer gadgets, and household gizmos with built-in power supplies. The lithium-ion battery, which can be painted on to virtually every surface, works by 'spraying on' the chemical layers which form a battery. The new battery could make solar gadgets practical by building up their storage, without hefty long-life batteries building up their bulk. It has already been tested on bathroom panels, producing a steady 2.4 volts and being recharged by a solar cell, says Nature's Scientific Reports. Hailed as a 'paradigm changer' by creators at Rice University the technology could one...

    A startup based in Cambridge, MA--Joule Biotechnologies--today revealed details of a process that it says can make 20,000 gallons of biofuel per acre per year. If this yield proves realistic, it could make it practical to replace all fossil fuels used for transportation with biofuels. The company also claims that the fuel can be sold for prices competitive with fossil fuels.

"We like to say that the big bang is nothing special in the history of our universe," said Sean Carroll, an Assistant Professor in Physics at the University of...

    PASADENA, Calif. - The Opportunity rover turned its panoramic gaze on the horizon and captured a dusty blue sunset at the end of its 20th day on Mars. The six-wheeled robot snapped photographs not for the sake of beauty, but because scientists want to learn about the properties of dust in the atmosphere. "It's pretty cool," pancam lead scientist Jim Bell said Thursday at NASA (news - web sites)'s Jet Propulsion Library as he showed a movie made from images recorded about three minutes apart. A bluish tint and rapid dimming of the sun at the horizon were caused by...

    MIT's plasmatron cuts diesel bus emissions, promises better gas engine efficiency October 22, 2003 MIT's plasmatron cuts diesel bus emissions, promises better gas engine efficiency A bus in Indiana is the latest laboratory for MIT's plasmatron reformer, a small device its developers believe could significantly cut the nation's oil consumption as well as noxious emissions from a variety of vehicles. The work will be the subject of an invited talk next Thursday, October 30, at a meeting of the American Physical Society's Division of Plasma Physics in Albuquerque, NM. The researchers and colleagues from industry report that the plasmatron, used...
