Instead of fossil fuels going in your gas tank, how about adding a pinch of salt? That may be the case in the future as a new process is under development to convert a type of salt into a biofuel. New properties of imidazolium salts (IMSs) could convert carbohydrates into versatile chemical compounds for biofuel production, according to a study by researchers at Singapore's Institute of Bioengineering and Nanotechnology (IBN). Biofuels are currently the only sustainable source of liquid fuels available, but the lack of highly efficient methods to convert carbohydrates into chemical compounds for biofuel production is one reason for the slow down in any replacement of petroleum feedstock by biomass.

Nearly 90% of those responding to a new survey by the Consumer Electronics Association said environmental factors such as energy efficiency would play a role in their decision to buy their next television. But because there is no one standard about what it actually means for a product to be "green," the study shows that consumers also are confused by claims to that effect. Less than half of the 960 people surveyed said they're generally able to make sense of the environmental attributes attached to electronics on the market. Tim Herbert, the C.E.A.'s senior director of market research, said that although consumers are confused by the green credentials of various electronics, "the key takeaway is the growing importance of 'green' in consumers' purchasing decisions."

Southern California Edison unveiled its newest power plant: 33,700 solar panels atop a warehouse in Fontana that will feed green energy directly into the grid. It's the first piece of what the utility says could become the largest rooftop solar installation in the world, a swath of photovoltaic panels spanning two square miles. The 600,000-square-foot warehouse rooftop, owned by ProLogis Inc., is the first of 150 commercial buildings that Edison is looking to outfit with solar panels over the next five years. Collectively, solar panels on all those roofs would provide 250 megawatts of electricity, enough by Edison's reckoning to power more than 160,000 homes when the sun is shining. Read More.
Intel is researching technology to harvest free energy from the environment, which could lead to devices such as mobile phones running for indefinite periods without recharging. The company said it was working on tiny sensors that could capture energy from sources such as sunlight and body heat. In the future, such energy could be used to power personal electronic devices such as cell phones. Recharging themselves by scavenging free energy allows the sensors to continuously record and transmit readings over wireless networks, without any human involvement. Read more.
Researchers at MIT have unveiled a new type of silicon solar cell that could be much more efficient and cost less than currently used solar cells. The design combines a highly effective reflector on the back of a solar cell with an antireflective coating on the front. This helps trap red and near-infrared light, which can be used to make electricity, in the silicon. The researchers applied their light-trapping scheme on thin silicon cells that are about five micrometers thick. Their prototype solar cell is 15 percent more efficient at converting light into electricity than commercial thin-film solar cells. Read More.
Also known as cogeneration, CHP is the simultaneous production of electricity and heat from a single fuel source such as natural gas, biomass, biogas, coal, waste heat, or oil. According to a report from the Oak Ridge National Laboratory, boosting the use of combined heat and power, or CHP, to 20 percent of generating capacity in the U.S. by 2030 would save 5.3 quadrillion British thermal units of fuel annually, the equivalent of nearly half the total energy currently consumed by U.S. households. The lab said there would also be a 60 percent reduction of the projected increase in carbon dioxide, the equivalent of taking 154 million cars off the road. Read More.
The first solar-powered car to travel around the world ended its journey at the U.N. climate talks, arriving with the message that clean technologies are available now to stop global warming."This is the first time in history that a solar-powered car has traveled all the way around the world without using a single drop of petrol," said Louis Palmer, the 36-year-old Swiss schoolteacher and adventurer who made the trip. The car, which runs noiselessly, can travel up to 55 mph and covers 185 miles on a fully charged battery. Read More.
What if your house could generate electricity from the noise of the cars on the road? Or if the waste heat generated by your air conditioner could help put a dent in that expensive summer electric bill? As the demand for cheaper and more renewable energy sources increases, piezoelectrics - a class of material that produces an electric potential when mechanically deformed - may hold the key to unlocking the energy flowing all around us. There are applications of this technology already in place - certain dance clubs in Europe utilize dance floors with piezoelectrics to help power the lights. What would really be useful to the consumer, however, would be small piezoelectric systems that could assist in powering personal electronic devices. Read More.
The Embassy Festival of Trees, in Fort Wayne, Ind., features a new attraction this year: a tree powered by, possibly, you. The alternative-energy tree won't be sucking up electricity from Indiana Michigan's power grid. Rather, visitors to the Festival of Trees will be allowed to hop on a bike connected to a generator and pedal away. The generator creates energy that goes into a power pack that lights the tree. Because the power pack can store energy, the strand of lights will stay on for a while even when no one is pedaling. When the power starts running low, an alarm will sound indicating it's time to start pedaling again. Read more.
Scientists have found a very promising and clean source for energy that uses the slow movement of the currents under the rivers, oceans and streams to generate power. The new device, which has been inspired by the way fish swim, consists of a system of cylinders positioned horizontal to the water flow and attached to springs. As water flows past, the cylinder creates vortices, which push and pull the cylinder up and down. The mechanical energy in the vibrations is then converted into electricity. Read More.
China has decided to put 60,000 new-energy vehicles on trial run in 11 cities in the next few years as part of the pilot project of developing its eco-friendly, fuel-efficient alternative-energy auto industry, said sina.com today. China's EV (electric-vehicle)-oriented automakers, now only in a very small number, are required to reach the annual production of 500 new-energy vehicles by late 2009 and their total annual output should hit 10,000 units by 2010 for each of the chosen cities to have enough EVs for trial operation. At the same time, the vehicle standards, quality and stability will be strictly observed to meet the new-energy vehicle requirements. The Chinese government has invested at least 800 million yuan ($117.2 million) in developing the EV industry. Read More Here .
The Vatican on Wednesday activated a new solar energy system and announced an ambitious plan that could one day make it an alternative energy exporter. The massive roof of the "Nervi Hall" where popes hold general audiences and concerts are performed, has been covered with 2,400 photovoltaic panels to provide energy for lighting, heat and air conditioning. The new system on the 5,000 square meter roof will produce 300 megawatt hours (MWh) of clean energy a year for the audience hall and surrounding buildings. Officials say the Vatican is planning to install enough renewable energy sources to provide 20 percent of its needs by 2020, broadly in line with a proposal by the European Union. Read More Here.
Santa Coloma de Gramenet, a gritty, working-class town outside Barcelona, has placed a sea of solar panels atop mausoleums at its cemetery, transforming a place of perpetual rest into one buzzing with renewable energy. The power the 462 panels produces -- equivalent to the yearly use by 60 homes -- flows into the local energy grid for normal consumption and is one community's odd nod to the fight against global warming. The community's leaders hope to erect more panels and triple the electricity output. Before this, the town had four other solar parks -- atop buildings and such -- but the cemetery is by far the biggest. Read more here.
