New LED Streetlight Reduces Light Pollution and Saves Energy
Light pollution is one of the biggest sources of pollution worldwide. Because some chemical processes that cleanse the atmosphere only occur in the dark, light pollution prevents these chemical reactions to happen, thus contributing to the chemical pollution throughout the next day and so on. New streetlights designed by scientists in Mexico and Taiwan are now [...]

When burned, methane emits only half the carbon dioxide coal does, but when released freely into the atmosphere, methane is 20 times more powerful than CO2 as a greenhouse gas, and its contribution to climate change has been estimated to 30%. A team led by Berend Smit at Berkeley performed a computer-aided study that found [...] Read more... | A team of researchers at the University of Wollongong in Australia has developed a new type of battery that can hold up to 5 times the energy of already traditional lithium ion piles used in camcorders, phones and electric cars nowadays. The new battery uses a Germanium-based material and has the potential to double the [...] Read more... |
A new solar-powered device developed at the Pacific Northwestern National Laboratory (PNNL) by researcher Robert Wegeng could reduce the CO2 emissions of natural gas by up to 20 percent. Basically, what the device does is it takes the heat obtained by concentrating sunlight through the usage of a parabolic dish (solar concentrator) and uses it to transform [...] Read more... | It may take 40 more years to decommission the Fukushima power plant, said a team from the International Atomic Energy Agency recently. The damage, they say, is so complex, that it’s not possible to predict how long the cleanup may last, but in either scenario it won’t take less than 30 to 40 years. The [...] Read more... |
As part of a reinvention plan, BYD Co, a large Chinese brand with Warren Buffet as an investor, might shift its focus from conventional automobiles to new energy battery models within two years. At one point, BYD had dreams of being a competitor of Toyota, but after shares have tumbled by 75% since late-2009, the [...] Read more... | In recent years, more and more vehicles are of the front-wheel drive type, with the Ford Focus being no exception. German firm Schaeffler has elected to convert a Ford Fiesta into a rear-wheel drive, fully-electric car. Utilizing wheel hub motors in its conversion, the driving dynamics of the car have been completely changed; perhaps a [...] Read more... |
Few items have universal appeal, and when you mention hybrid to some people, they’ll automatically think of Toyota Prius. Toyota hybrid vehicles can be so much more, the range including everything from the compact Toyota Prius c to the luxury Lexus LS600h. Toyota hybrid vehicle technology, nineteen models in all, has been gaining popularity around [...] Read more... | Working under the radar for years, Zinc-Air Inc. is probably a battery company that you’ve never heard of, but now that they’re maybe six months away from marketing a new grid energy storage battery, they’re coming out of hiding. Who can blame them? Startup battery companies have often overhyped, not only their technology, but also [...] Read more... |
BMW is partnering with Chinese company Brilliance to manufacture and sell electric vehicles in China under a new brand, Zinoro. The world’s fastest growing car market is in China, which makes manufacturing and selling vehicles there a good prospect. BMW is China’s 2nd-biggest luxury auto manufacturer, the plant in Shenyag making the 3- and 5-Series [...] Read more... | The ability to dissociate light into fundamental colors could make today’s solar panels 50 percent efficient. If you compare this figure to the 20 percent efficiency found in many solar cells on the market, that’s a game-changer. Harry Atwater, a professor of materials science and applied physics at Caltech thinks he has the solution. The [...] Read more... |
An old World War II bunker used for sheltering 30,000 people in Hamburg is going to be transformed into an energy-generating facility that will provide heat for 3,000 homes and electricity for 1,000, reports Inhabitat. A large solar array has already been attached to the roof and exterior, and an open-air terrace will open this [...] Read more... | A new nano-filter powered by sunlight can clean large bodies of water from antibiotics and carcinogens. The device, developed by the University of Cincinnati, is much more effective than the activated carbon that’s currently being used for this purpose. Two bacterial proteins absorb about 64 percent of the antibiotics in surface water. For a comparison, [...] Read more... |
