Wind Tunnel Concept Converts Wind Energy Generated by Subway Trains into Electricity
Metropolitan cities around the world build more and more underground subway systems in order to minimize the number of vehicles on the roads. The industrial designers also though to help city authorities by redesigning the current systems, making them more efficient.
Sanyo Saves Air Conditioning/Lighting Energy In Offices By Using Camera System
Sanyo Electric Co., in an initiative to reduce their carbon footprint and at the same time to save money, is experimenting with a system composed of cameras that assess how many persons are in a certain room and regulates air conditioning and lighting according to the results.
GreenDroid: Newly Developed Smartphone Chip Uses 11 Times Less Energy Per Instruction
Smartphones are looked upon as the most sophisticated and trendy devices there are on the market nowadays, since mostly everyone wants or uses one. Still, with the coming of Google's Android and the freedom from Microsoft's Windows Mobile, no big changes have been made to green up these devices, as their power consumption grows exponentially.
Researchers Find New Way to Make Less Toxic Super-Fast Graphene Transistors
Graphene has a great potential to make electronic devices such as phones, radios and computers smaller and faster. The new graphene-based technology could play a key role in waste reduction and energy conservation.
Nanotube-Based Water Purifier From Stanford Filters Water Quicker, Kills Bacteria
Dangerous bacteria can often hide in the water you drink, but they're not harmful until they reach a certain number to become active inside your body. Regular water purifying technologies consume a lot of power, but a team of Stanford researchers have developed a new low-cost, high-speed filter that works differently than other purifiers.
New Display Technology Uses Gratings to Control Color, Enhances Efficiency 400%
LCDs have been here for quite a while, using the same technology implemented for the first time in the 1970s. It's high time someone invented a different method of displaying colors in a controlled manner, for the sake of price and energy consumption.
Concrete Bases to Increase Wind Turbine Efficiency for Better Power Production
The use of concrete bases can prove significantly profitable, considering wind turbine towers, as this has to do with diminishing, by more than two-thirds, the quantity of concrete used for the footings of a single tower.
Graphite Foam Reduces Temperature of LEDs, Making Them Cheaper and Longer-Lasting
LED lights, yet not cutting edge idea for lighting, are in vogue nowadays, as they evolve by the year. Now, a group of researchers from Oak Ridge National Laboratory has discovered how to make LEDs last for longer and also lower their price.
Hygroelectricity: A New Type Of Alternative Energy, Extracted From Air's Electrical Charge
In their search of alternative energy resources, scientists have stopped at a phenomenon that, although known for ages, brought them surprises. They want to harvest electricity by profiting from the fact that air is loaded with electric charges, and work on a prototype for such a harvester.
New Mitochondria Fuel Cells Could Generate Electricity From Sugar or Fats
Mitochondria, also called "the cells' powerhouses", may one day replace batteries as we know them. Scientists from the University of Missouri invented and developed a new fuel cell based on these also called "organelles" (the internal organs of cells). The fuel cell is able to feed on sugars and fats, just like mitochondria in the organisms do.
