Researchers have discovered that graphene allows positively charged hydrogen atoms or protons to pass through it despite being completely impermeable to all other gases, including hydrogen itself.
The implications of the discovery are immense as it could dramatically increase the efficiency of fuel cells, which generate electricity directly from hydrogen, the scientists said.
The breakthrough raises the prospect of extracting hydrogen fuel from air and burning it as a carbon-free source of energy in a fuel cell to produce electricity and water with no damaging waste products.
Browser based Peer to Peer (P2P) free file transfer services require no installation of any program. There is no file size limit. As its P2P there is no uploading, just a direct transfer of files from your computer to your friend's.
How it works:
You just select the file to transfer. The service gives you a download link to share with anyone. Then the service creates a connection between you and whoever you share the link with so your file is not uploaded anywhere; rather, the link serves only as a gateway for transferring the file from your computer to the recipient.
The article lists and links eight free p2p file sharing services...
Joe Justice presents at TEDxRanier how Team WIKISPEED has accomplished amazing results in producing a 100 Mile per Gallon (MPG) car using processes borrowed ...
...from the software world; Agile, Lean, Scrum and Extreme Programing. The result is that WIKISPEED now sells an affordable car that achieves 100 MPG that is is fast, fun and beautiful while also achieving a five star crash test rating equivalent.
This is the future of real distributed manufacturing. Small shops, won't call them factories, that can make anything for you from a pickup truck to a neat new washing machine that uses ultrasound to clean the clothes, from sneakers like no one else has to a personal web server in a wall plug. The possibilities seem endless...
We can obtain renewable, clean, safe, cheap energy by annihilation, for example, of an electron with an anti-electron (positron). An electron and positron are obtained by extracting them from atoms; the extraction consumes a negligible amount of energy. Then, the two particles are brought near one another (collision).
The phenomenon of annihilation occurs when particle rest mass is converted totally into energy (gamma photons). Gamma photons occur as much as needed to retrieve the total energy of the electron and positron (rest energy and kinetic energy)...
Kale grows to maturity in 55 to 60 days versus a cow raised for beef for an average of 18-24 months. Kale can grow in most climates and is relatively easy and low impact to grow at home or on a farm. To raise one pound of beef requires 16 pounds of grain, 11 times as much fossil fuel and more than 2,400 gallons of water.
Researchers at the University of Illinois at Urbana-Champaign have developed a new lithium-ion battery technology that is 2,000 times more powerful than comparable batteries. According to the researchers, this is not simply an evolutionary step in battery tech,
MIT is reporting that it has created a new, cheap material -- using a microwave, no less -- that converts sunlight into steam with an amazing 85% efficiency. This could have major repercussions in the realms of desalination and sterilization, and perhaps for concentrated solar thermal power generation as well.
Stefan Hartmann of Overunity.com has posted two videos of a Russian group (friends of Tariel Kapanadze) apparently powering a stand-alone engine on water. They drink from a bottle of water (of course, it could be Vodka), then pour the liquid into what appears to be a fuel tank. Then they start up the engine.
As it's running, they show the exhaust being clean. As they hold a cup at the exhaust, it collects liquid (assumed to be water), which they then drink.
The Phase-shift Plasma Turbine is a modified version of the Electrodynamic Space Thruster in order to operate in atmospheric environments, mainly during takeoff, and in space to reuse exhaust gases from chemical rockets to boost the overall ISP, enhancing utilization of both energy and propellant.
The Phase-shift Turbine uses a set of concentric coils, axially rotated in relation to each other, and feed by phased RF sources, producing radial and longitudinal sequences, which results in helical moving force, ionizing intake gas/particle/ion, generating continuous unidirectional thrust.
Marnoch Thermal Power: a new type of heat engine for tapping into lower temperatures My latest Clean Break column on Ontario inventor Ian Marnoch and his new heat engine design that could make efforts at turning low-grade heat into electricity more economical.
It’s also a nut Ian Marnoch of Port Severn, Ont., is trying to crack. For the past seven years the Ontario inventor has been developing a new kind of “heat engine” that he says can generate electricity more economically from lower-grade heat. And that heat could come from anywhere: the ground, the sun, or an industrial waste process.
Not that the technology doesn’t already exist to do it. There are other heat-engine technologies out there, most notably those based on the Organic Rankine thermodynamic cycle. These systems transfer heat to a working fluid with a low boiling point, such as ammonia.
As the fluid heats up, expands and vaporizes it drives a turbine that generates electricity. The vapour is then cooled, condensing it back into a fluid which is recycled back through the process.
Marnoch’s heat engine works under a different principle. There is no vaporization of fluids. Instead, the Marnoch system relies on dry pre-pressurized air that expands and contracts as it is heated and cooled, causing pistons to turn that generate electricity.
Groundbreaking new research has linked sodium fluoride and water fluoridation to cardiovascular disease atherosclerosis, the leading cause of death worldwide.
Groundbreaking new research has linked sodium fluoride to cardiovascular disease, the leading cause of death worldwide. Researchers found that fluoride consumption directly stimulates the hardening of your arteries, a condition known as atherosclerosis that is highly correlated with the #1 killer. Sodium fluoride is currently added to the water supply of many cities worldwide, despite extreme opposition from health professionals and previous studies linking it to decreased IQ and infertility.
In their research, scientists examined the relationship between fluoride intake and the hardening (calcification) of the arteries. Studying more than 60 patients, the researchers found a significant correlation between fluoride consumption and the calcification of your arteries.
THE world may soon be able to buy one of the Far North's most controversial yet revolutionary inventions.
The Lutec draws its power from a bank of batteries, with the motor turning due to powerful permanent magnets at its core being attracted and then repulsed from steel cores of fixed coils.
It does not work via perpetual motion, rather it relies on natural magnetic forces and a pulsed electrical input.
The results of the generator were verified by independent engineers from SGS Australia following a test earlier this year, which confirmed the energy output from the generator was indeed greater than its input.
Mr Christie said he and Mr Brits were currently working on a production prototype to suit the domestic market, which they hoped to produce locally.
