Hydrogen Fuel Cell Powered by Alternative Sources
The fact that hydrogen fuel cells are powered by gas coming from fossil fuel made Japanese scientists invent other alternative sources of hydrogen like dough and sewage.
NIST Invents Breakthrough High Temperature Stable Biodiesel
Biodiesel has recently become a very controversed biofuel. It can be obtained from vegetable oil, animal fats, used cooking oil, microalgae and is a potential replacement of petroleum-based diesel fuel. By doing some research, NIST scientists found out some additives that make biofuels act better at high temperatures.
Harvesting Wind Power From Any Direction With Cylindrical Turbines
The use of wind power has been around for centuries, from the simple sail to the sophisticated windmills. The inconvenience of harvesting wind energy is that most of wind-farm sites are placed far away from the areas that need the power.
Ian`s Solar-Heated Air Balloons Could Harness 500kW Each
How would you like an engine producing your dear electricity? How would you like that engine to have pistons as high as heat-powered balloons? Well, an environmental consultant from Solartran in Brisbane, Australia, by his name Ian Edmonds, has designed such an energy producing "engine" from the classic and romantic air balloon.
Is Nitrogen a Climate Savior?
National Science Foundation proved after a long study that nitrogen added to soil can make forests absorb more dioxide carbon. But even if nitrogen is one of the most abundant element in the atmosphere, it's still a pollutant and can have a dramatic influence on the planet's environment.
Home Wind Turbines Prove To Be Less Efficient
Though many would have though that having installed home wind turbines, electricity would not be a problem anymore it seems things do not look that encouraging.
StARS: Start-Stop Hybrid System Reducing Fuel Consumption Up to 25%
In the battle to have the most efficient engines, one of the biggest allies is the European Union and the laws they make to force the car companies to lower the harmful emissions. By 2012 they set a maximum of 130 g/km carbon-dioxide (CO2) emission.
Aberdeen Researchers to Find Low-Temp Fuel Cell Solutions
Current hydrogen fuel cells work at temperatures for up to 100°C for PEM types, and up to 300°C for SAFC (solid acid). The problem with these, although I don't agree with their developmental direction, is that they don't tolerate carbon very easily, and pure hydrogen is very hard to obtain from carbon-rich sources, such as methane or petrol.
I Charge My Batteries With Water. How About You?
You go somewhere for the holidays. You have your mp3 player to forget about the "dead times" during not-so-interesting-travels. But what? Suddenly your mp3 player stops working! Noooo!
Freshwater and Electricity Through Osmosis
Robert McGinnis, Yale doctoral student and Menachem Elimelech, Chair of Chemical and Environmental Engineering, have developed systems that can harness the power of osmosis to transform non-potable water sources like seawater to freshwater and generate in the same time electricity.
