The Magnetic Air Car: a Step Towards Free Energy Devices?
San Jose's West Coast Green conference from last week had a point of attraction: the world's first fuel-less car, made by Magnetic Air Car. They even say it will be produced beginning with 2010.
100 Year-Old Aerodynamics Problem Solved: Could Increase MPG Dramatically
MIT researchers discovered the solution to a problem put 100 years ago by Ludwig Prandtl. It refers to the situation when, for example, a car accelerates up and down a hill, then slows to follow a turn, and the airflow around it cannot keep up and separates from it. This aerodynamic phenomena creates an additional drag, slowing the car, and forcing you to push harder on the pedal, consuming more gas.
New Electric Field Device Reduces Car Fuel Consumption by 20%
Professor Rongija Tao, from Temple University, invented a device that, applied to the vehicle's fuel line, near the injectors, creates an electric field that reduces the fuel's viscosity, so that smaller droplets are injected into the engine, leading to better combustion and increased fuel efficiency as much as 20%.
Mercedes S400: True Hybrid Car, or Just Greenwashing?
Is this "greenwashing" phenomena affecting everybody lately? I understand we're in the middle of a hybrid-crusade, and beginning with all the movie stars and all celebrities, everybody wants to produce and buy a hybrid car, but to bring out a hybrid car only to stick the "hybrid" green stamp on it seems a little overwhelmingly green-washing style.
Solar Cube: Saving Lives With Solar and Wind Power
What can you buy for $38,000? Two second-hand Priuses? No. A smaller airplane? Neither. I'll tell you what you can have for that money: a solar powered desalination device.
New York`s Tidal Turbine Powering a Supermarket
New York city wants to build about 300 turbines in their waterway. NY's East River has strong, fluctuating currents, allowing an efficient generation of electricity. Once built, the wave-powered system can generate enough for 10,000 homes.
LiFePO4 Batteries: Chevy Volt`s Future Energy Sources
The Lithium Iron Phosphate (LiFePO4) batteries are based on Lithium Ion, but they offer many advantages over LiCO2 (Lithium Cobalt), frequently used in laptops, mp3 players and cell phones. They also offer a greater range, power and safety, in an electric vehicle - they will not explode or catch fire if overcharged.
Einstein’s Refrigerator Using No Electricity/No Freon Revived at Oxford
It seems like Einstein did his best not only in quantum physics, but also in classic, immediately-helpful science. Back in the 1930's, helped by his friend Leo Szilard, he invented a refrigerator that used no electricity at all. Scientists from Oxford are struggling to revive his invention today.
Mobion: High Power Fuel Cell Batteries for Your Gadgets Starting 2009
Just two days ago, MTI MicroFuel Cells Inc. has made a press release for their third generation Mobion chip, a portable fuel cell powered device aimed for small-scale devices, such as iPods, media players and mobile phones.
Scientists Making Hydrogen Efficiently from Water Steam
Trying to make hydrogen a viable fuel, economically and energetically, a team of researchers from Idaho National Laboratory splits water steam into hydrogen and oxygen using electrolysis, but from steam, and at a high temperature.
