New Korean Li-Ion Battery Lasting 8 Times More
South Korean professor Jaephil Cho (and, of course, a team of his students) from Hanyung University have developed a lithium-ion battery that lasts eight times longer than the actual models do.
Quantumsphere, on the other hand, presented last september a Li-Ion battery with a new that lasts five times more than traditional ones.
New Electron Cooling Discovery to Extract More Energy from Solar Cells
Do you know that electrons can be "cooled"? The cooling of an electron, in lay language, is the transitory state in which the electron passes from a high-oscillation state to a low-oscillation, normal state. The high oscillation state is given by an external stimulus, i.e. electric voltage.
New and Cheap Way to Make Graphene for Hydrogen Storage
A team of UCLA scientists (Yang Yang and Richard Kaner), located at the California NanoSystems Institute (CNSI), have discovered a technology of making graphene sheets in big quantities and at a low price. Graphene is being used to soak up hydrogen and store it efficiently.
Flexible Charge Pump: Harvesting Mechanical Energy Through Zinc Oxide Wires
Researchers from Georgia Institute of Technology developed a new type of small-scale electric power generator, based on stretching and releasing zinc oxide wires encapsulated in a flexible plastic with two ends bonded.
Tiniest Solar Cell Invented to Power Microscopic Devices
The green energy movement has brought, like wars brought technological advances, a wave of alternatively-powered inventions, among which it is the most recent miniature solar cell, designed to power microscopic machines.
Kandle Heeter – How to Heat Up Your Room Using a Candle
Doyle Doss, a Northern California Inventor, has created a candle powered space heater. It sounds like science fiction, but it really is a simple and green energy device, that could save you a lot of money by only lighting a candle, in the long run. The CO2 output of a candle is too small to mention, and the materials that this device is made of are all here since the Earth exists.
New Anti-Reflective Coating Make Solar Panels Absorb 96.2% Sunlight
I like the way science evolves and still, for years, nobody seems to look at the new inventions. This may be the case with solar, because almost weekly we discover news about useful inventions in the area of solar power. Instead, old and inefficient methods are still being commercialized and "promoted", at their high prices, like it's wanted to decrease their real usage in real life conditions, not promote it.
DIY Vertical Axis Wind Turbine Design (VAWT) from PVC Pipes
In this consumerism ruled times, the world needs to know ways to do stuff. When electricity generation is predicted to become more expensive (it's like they predict an invasion of electric vehicles), people need to build their own power generating systems for their independence.
Fraunhoffer Unveiled Pressure Sensors Powered by Self-Produced Green Electricity
Fraunhofer researchers from Stuttgart have developed a new technology that enables the production of energy-autonomous and thus low-maintenance sensors.
Latest Trend: Human Movement Powered Devices
Remember those movies presenting slaves hundreds of years ago spinning a huge wheel to provide the emperor with water and energy? They did not do it for fun, yet nowadays there are two recent mediatized inventions that caught my eye. Curiously enough, they are being developed by two telecom operators: Orange and NTT.
