US researchers power up world`s smallest fuel cell
Researchers at the University of Illinois have developed a fuel cell measuring just three milimetre square, raising the prospect of small water-powered fuel cells one day being used to provide zero carbon power for mobile phones and other handheld devices. The 1mm thick unit currently generates just milliamp at 0.7 volts and could already be used to power microbots and simple electronics systems. Historically, the size of fuel cells has been constrained by the need for the pump to deliver the external fuel supply, which has been a relatively power-hungry component. However, the Illinois team ... |

Nuclear regulators to review environmental modelling for radiation safety
Issues of radiation safety and environmental protection go hand in hand. At the IAEA last week, experts from 40 countries examined the transfer of radionuclides to plant and animal life, to improve how risks are assessed and ultimately reduced. `All nuclear facilities and uranium mines, in their day-to-day activities, release some amount of radioactive effluents into the environment, transferring to the food chain, the air you breathe or to the water you drink,` says Didier Louvat, Head of the IAEA´s Waste and Environmental Safety Section. ”Of course, before governments give authorisation for ... |
