Simple device which uses electrical field to boost gas efficiency developed by Temple University researcher Rongjia Tao, Temple University, 215-204-7651 or rtao@temple.edu With the high cost of gasoline and diesel fuel impacting costs for automobiles, trucks, buses and the overall economy, a Temple University physics professor has developed a simple device which could dramatically improve fuel efficiency as much as 20 percent. According to Rongjia Tao, chair of Temple’s Physics Department, the small device consists of an electrically charged tube that can be attached to the fuel line of a car’s engine near the fuel injector. Six months of road testing in a diesel-powered Mercedes-Benz automobile showed that the device increased highway fuel from 32 miles per gallon to 38 mpg, a 20 percent boost, and a 12-15 percent gain in city driving. The results of the laboratory and road tests verifying that this simple device can boost gas mileage was published in Energy & Fuels, a bi-monthly journal published by the American Chemical Society.

Vivienda Makelaardij Spain to Put 1 million Electric Cars on the Road Spain intends aims to put 1 million electric cars on the road by 2014 as part of the Zapatero government’s plan to save energy and boost energy efficiency, minister of industry, business and tourism Miguel Sebastian said Tuesday. The Plan, which Spain’s Council of Ministers are expected to approve August 1, will be enacted this year and carry on through 2011. Spain will save between 5.8 and 6.4 million tons of oil over the three-year period as a result, according to industry ministry estimates. “The electric vehicle is the future and the engine of an industrial revolution,” Sebastian told members of the national industry commission. Higher oil prices and growing use and intensity of fossil fuel cost Spain some 17 billion euros last year, according to the minister.

UK | Human species may split in Humanity may split into two sub-species in 100,000 years' time as predicted by HG Wells, an expert has said. Evolutionary theorist Oliver Curry of the London School of Economics expects a genetic upper class and a dim-witted underclass to emerge. The human race would peak in the year 3000, he said - before a decline due to dependence on technology. People would become choosier about their sexual partners, causing humanity to divide into sub-species, he added. The descendants of the genetic upper class would be tall, slim, healthy, attractive, intelligent, and creative and a far cry from the "underclass" humans who would have evolved into dim-witted, ugly, squat goblin-like creatures. Race 'ironed out' But in the nearer future, humans will evolve in 1,000 years into giants between 6ft and 7ft tall, he predicts, while life-spans will have extended to 120 years, Dr Curry claims. However, Dr Curry warns, in 10,000 years time humans may have paid a genetic price for relying on technology.
Werkgroepen presenteren plannen miljardenbezuinigingen | nu.nl/p DEN HAAG - De twintig ambtelijke werkgroepen die in september door het kabinet aan het werk zijn gezet om het overheidstekort terug te brengen, hebben donderdag hun bevindingen gepresenteerd. Foto: ANP Bekijk video Via vijf varianten kan de woningmarkt zo aangepast worden dat die beter gaat functioneren, zowel voor huurders als voor huiseigenaren. Een variant, met een mogelijke opbrengst van 5 miljard in 2015, gaat er vanuit dat de eigen woning gelijk wordt gesteld aan andere vormen van vermogen. Een andere variant gaat ook uit van hogere huren, maar daarnaast van een beperking van de hypotheekrenteaftrek: maximum aftrekpercentage van 42 en een hypotheekschuld van maximaal 500.000 euro. Deze variant levert 3 miljard op in 2015 en 6,5 miljard in 2020.

Toyota, Nissan, Mitsubishi to Standardize Electric Car Rechargin Trying to spread adoption of electric cars, five major Japanese firms have agreed to set a unified standard for electric vehicle recharging stations. First, the companies will address a Japanese national standard, then they will push for an international standard, reports Reuters. The group is comprised of Toyota, Nissan, Mitsubishi, Fuji Heavy Industries and Tokyo Electric Power – Japan’s biggest utility. Officially, the group is calling itself the “CHAdeMO Association.” “CHAdeMO” is an abbreviation of “CHArge de MOve,” which translates to “charge for moving.” Symantics aside, the group started to come together last August when Nissan, Mitsubishi, Fuji and the utility started a preparatory committee. So far, 158 businesses and government bodies are expected to join the association. In other alternative vehicle charging news, Honda is touting its home solar hydrogen refueling station.
Groundbreaking Energy Ball Wind Turbine for Home Power Swedish company Home Energy recently revealed an innovative wind turbine that spins in a spherical formation. Eschewing traditional rotors for a sleek orb structure, this beautiful rethinking of conventional wind turbine design utilizes the Venturi principle, which funnels wind within the turbine’s blades. The resulting spherical wind turbine features increased efficiency and lower noise levels – making it ideal for small scale energy needs such as personal home use. Most modern wind turbines utilize a flat three-blade design, wherein the head of the windmill is directed into drafts by a computer. This results in highly efficient turbine that can take advantage of very low wind speeds. + Home Energy Via FooZooDesign Tip Via Ella
Differential Evolution Homepage for Continuous Function Optimization (an algorithm by Kenneth Price and Rainer Storn) Table of contents History Differential Evolution grew out of Ken Price's attempts to solve the Chebychev Polynomial fitting Problem that had been posed to him by Rainer Storn. A breakthrough happened, when Ken came up with the idea of using vector differences for perturbing the vector population. Basics DE is a very simple population based, stochastic function minimizer which is very powerful at the same time. Basically, DE adds the weighted difference between two population vectors to a third vector. Practical Advice If you are going to optimize your own objective function with DE, you may try the following classical settings for the input file first: Choose method e.g. Keep in mind that different problems often require different settings for NP, F and CR (have a look into the different papers to get a feeling for the settings).
