L'arrêt de réacteurs nucléaires allemands menacerait cet hiver la France de pannes d'électricité
Exportatrice d'électricité durant presque toute l'année, la France est néanmoins importatrice lors des grands pics quotidiens l'hiver notamment autour de 19 heures. A cause du chauffage électrique, l'Hexagone est aussi le pays d'Europe dont la consommation augmente le plus par grand froid : pour chaque degré de température extérieure en moins, 2 300 mégawatts de puissance supplémentaire sont nécessaires, soit plus de deux réacteurs nucléaires, selon le transporteur d'électricité RTE.
First Google.org-funded geothermal mapping report confirms vast coast-to-coast clean energy source
New research from SMU’s Geothermal Laboratory, funded by a grant from Google.org, documents significant geothermal resources across the United States capable of producing more than three million megawatts of green power - 10 times the installed capacity of coal power plants today.
Team says Arctic ice shelf broke up before
Now however, new research by a team from Université Laval in Canada, led by Dermot Antoniadesa, have found, after studying sedimentary material on the bottom of the Disraeli Fiord, created by backup from an ice shelf in Northern Canada, that it experienced a major fracture that resulted in an overall reduction of the ice shelf some 1,400 years ago.
Breakthrough furnace can cut solar costs
NREL researchers continue to improve the furnace and expect it to be able soon to hike the efficiency by 4 percentage points, a large leap in an industry that measures its successes a half a percentage point at a time. "Our calculations show that some material that is at 16 percent efficiency now is capable of reaching 20 percent if we take advantage of these photonic effects," NREL Principal Engineer Bhushan Sopori said. "That's huge."
Northern lights take unusual trip down south
Space weather forecast chief Bob Rutledge said given the size of the solar storm that occurred last night, the lights probably shouldn't have been visible south of Iowa. Rutledge said the storm was unusual, its effects reaching Earth faster than forecast. The storm caused no damage to technology as it sometimes does.
Japan parliament hit by China-based cyberattack
Computers in Japan's lower house of parliament were hit by cyberattacks from a server based in China that left information exposed for at least a month, a report said Tuesday. The government's top spokesman Osamu Fujimura, pictured in September 2011, said he was not previously aware of the reported attack but that the government was investigating the issue.
Computers in Japan's lower house of parliament were hit by cyberattacks from a server based in China that left information exposed for at least a month, a report said Tuesday.
Japan cyberattackers may have military info: report
Mitsubishi Heavy said late last month that 83 computers at 11 of its facilities had been hit by cyberattacks but no leakage of information on products and technologies had been confirmed.
New approach to solar power with hybrid solar-thermoelectric systems
The novel arrangement proposed by Wang and graduate student Nenad Miljkovic embeds a thermoelectric system in the central tube of a parabolic-trough system so that it produces both hot water and electricity at the same time. The key to making this work is a device called a thermosiphon that draws heat away from the “cold” part of a thermoelectric system, maintaining its temperature gradient.
