Eco Trees was created to show people news about alternative energy and environment. We, at Eco Trees, believe that by this way we will help people save the nature and be more environmentally friendly.
The burning hot sun at the equator is a far cry from the weak sunlight that reaches higher latitudes. To make the most of such different conditions you need specially tailored solar cells, according to UK firm Quantasol. Read the rest of this entry »
The company Infinite Power Solutions(IPS) has developed a new range of high-density flexible batteries that could revolutionize renewable energy systems. The manufacturer says these tiny, rechargeable, thin-film batteries combine the energy density of traditional batteries with the high discharge current of supercapacitors. With some models measuring just 0.5in. square (12.7mm) and less than .01in. thick (0.17mm), IPS claims these are the most powerful batteries for their size. Read the rest of this entry »
The companies Algenol Biofuels and Dow Chemical have partnered to build algae farms that can turn carbon dioxide into ethanol as a vehicle fuel or an ingredient in plastics. The team has announced that they will build a demonstration plant that would effectively convert CO2 into fuel. Read the rest of this entry »
When Movement Climbing and Fitness will open its doors in July, its water will be heated with a 90-square-foot evacuated tube solar thermal system and its electricity will be produced by a 100-kilowatt photovoltaic array. Read the rest of this entry »
Geoff Bjorgan is the inventor of this amazing “green” motorcycle. He successfully converted a 1986 Honda motorcycle into a 120 lbs electric, pedal-assist bike. “I was more concerned with look than function,” Bjorgan told Autopia. “The bike is heavy, definitely a flatlander, but it cruises at 21 mph so I’m happy.” Read the rest of this entry »
China’s officials said that until 2020, the country will build a huge wind farm in the northwest, having an energy capacity similar to the gigantic Three Gorges Dam. Feng Jianshen, a vice governor of Gansu province, told reporters that the province planned to expand the installed capacity of its wind power base to more than 20 gigawatts in 11 years, more than 10 times the current level.

Yuneec’s E430 is a twin seat, single engine, LSA class aircraft with a significant difference to every commercially available plane that has come before it – it’s entirely electric. The lightweight composite-construction E430 charges in three hours from a domestic 230 volt powerpoint, runs for two and half hours on a charge and the all-up cost will be USD$89,000 when it goes on sale this time next year.

Researchers at the Purdue University have discovered a new technology that saves energy and servicing costs by indicating when air conditioners are low on refrigerant, preventing the units from working overtime. The new “virtual refrigerant charge sensor” is particularly practical for automotive air conditioners, which tend to leak refrigerant more than other types of units. Read the rest of this entry »
An environment-friendly washing machine developed by the researchers at the University of Leeds, Britain, that is able to wash a complete load using just one cup of water, could be released on the market next year. Read the rest of this entry »
