New MOSFET-based Device Makes Ultra Low Power Green Sources Usable
A company called Advanced Linead Devices, from Sunnyvale, CA, has designed a MOSFET (a power transistor, you may have one your stereo at home - it basically looks like the picture above) that can open itself to very tiny, small, voltages, and it's called "zero-threshold MOSFET".
Solvatten: Solar Powered Water Purifier for the Poor
While most new inventions are for wealthy people, with some social status, once in a while there are inventions aimed to help the poor and provide the minimal sanitary conditions through simple and inexpensive methods.To get one liter of boiling water you need one kilo of firewood. People living in areas with no safe water usually spend 3-10% of total income/year on water.
Wastewater Mixed With Petroleum Could Reduce Emissions by 84%
Taiwanese scientists discovered that a new fuel can be made by combining industrial wastewater and petroleum oil. The new fuel's efficiency is increased by 14% and is a friendly way to treat industrial wastewater as well. The new fuel could eliminate the expensive treatment of industrial air emissions from boilers.
New 13kg Oxford Electric Motor Delivering 3 Times More Power and 97% Efficiency
Following the development of batteries and, generally, electricity storage, the UK-based firm, Isis Innovation Ltd has developed a new revolutionary electric motor that outperforms the old ones by having the materials and a little of the working principles modified inside them.
New OLED Discovery Gives Light Quality of Incandescent Bulb
University of Florida researchers are on their way to discover the maximum efficiency of 100 lumen/W from a new type of LED lighting, having the advantages of both an incandescent bulb (light quality) and a fluorescent bulb (very low consumption).
Fridge Powered by Heat Invented at Stanford
We have been talking a while ago about refrigerators that needed no electricity or that were powered by the Sun, through evaporation, helping poor countries with a cool place to keep their food. Now, venture capitalist Adam Grosser teamed up with some Stanford scientists to create refrigerator that really doesn't need to be plugged in anything but the Sun.
New MIT Thin Film Solar Cells Brag 50% More Efficiency
MIT researchers invented new and improved thin film solar cells that present 50% more efficiency, while being much more cheap than classic solar cells. Their price is due to using less silicon than conventional solar cells.
New Nano-Device Could Power Your MP3 Player from Surrounding Sound
Tahir Cagin, from the Texas A&M University, recently discovered that a specific type of piezoelectric material could convert sound waves into electric current 100 percent more efficient than current devices, when it is manufactured at a very small size - 21 nanometers.
Artificial Photosynthesis Succeeded Using Gold "Leaves"
Kane Jennings and Peter Ciesielski, along with a team of scientists from the Vanderbilt University in Nashville, Tennessee, have been working to create the world's first artificial leaf, that can do what natural leaves do: capture the light. More, their leaves transform that light into electricity. So, the nature's 3.5 billion years work is now to be synthesized in a lab experiment. Here's how they do it.
Your Home`s Excess Heat Could Get Recovered by New Cheap Machine
This article doesn't talk about huge producers of energy, or doesn't mention the use of any prime matter to create energy, but instead it focuses on recycled one. Ener-G-Rotors, a company based in Schenectady, NY, is developing a heat recycler that can work with lower quantities of heat, under 150°C, unlike those of the competitors, aimed only to the higher-class, industrial energy producing stations.
