Submission + - Angel Flight Pack enters last frontier of aviation (

sterlingda writes: "Isn't it about time we achieved the Jetson-like capability of personal flight via a jetpack type of apparatus? Raphial Morgado, inventor of the NASA-award-winning Massive Yet Tiny (MYT) engine, is setting forth to devise just such a flight pack, named after his company: Angel Labs, LLC. He says his systems will be comprised of two 3.5-inch diameter engines, one for backup, that would power a counter-rotating turbofan engine. "It would be practical and safe, with redundancy built in." But this is just his hobby. His primary objective is to go into production of a MYT engine that could be retrofit into existing cars, claiming that the energy density of his engine is so high that the engine size needed to retrofit an SUV would be a little larger than an alternator — tiny in comparison — even while having essentially the same cubic inch cylinder displacement. The resulting vehicle would have better performance, while achieving the mileage of a Prius."

Submission + - eCoupled hooks up with Energizer for wireless erg (

sterlingda writes: "Fulton Innovation's eCoupled technology(TM) has added Energizer to their list of partners that also include Motorola, and Texas Instruments, with a promise of wireless power products arriving on the market in 2009. eCoupled technology enables one power transmission device to cover the range of power needs from milliwatts to kilowatts — simultaneously — by dynamically adapting as it seeks resonance at high frequencies. They can power directly or charge devices. Until some distance can be achieved, the eCoupled approach merely eliminates the "plug in" step. It doesn't eliminate the constraints of distance to the recharge console. However, it does render a one-size-fits-all aspect for all portable devices. No doubt, it's a fun baby step toward a wireless power future. Those first few steps can be the most enjoyable. No doubt, there will yet be astonishing leaps in the future, including the ability to not be constrained by distance — something Nikola Tesla was working on a century ago. Someday we might catch up to him."

Submission + - Downwind Faster Than The Wind (

sterlingda writes: "Is it possible to build a device in which the forward motion (e.g. on a treadmill) turns a wheel that turns a propeller which provides enough wind propulsion to accelerate the device forward? Some investigators appear to have accomplished just this. One, who goes by "spork33" on his YouTube account, is convinced that existing laws of aerodynamics can explain this phenomena, and he is in process of composing a scientific paper for publication in a refereed journal that will detail the mechanics involved. Bear in mind that you will not be able to just plop this on a flat surface such as a gym floor, give it a good push, and it take off accelerating. The device on the treadmill is analogous to a cart going along with a tail wind of the same speed, and the mechanism makes it go faster than the tail wind."

Submission + - Raser Ribon-Cutting Ushers New Geothermal Era (

sterlingda writes: "Raser Technologies had a ribbon-cutting for their first geothermal plant Thursday. Senator Orrin Hatch, after whom the plant is named, praised the development as opening a new chapter in energy independence — one based on clean, renewable, and affordable electricity. He sees the Raser approach as opening the door for geothermal power in the United States, and even the world, to eventually account for as much as a third of the entire electricity production."

Submission + - Rowan University Replicates BlackLight Power Tech (

sterlingda writes: "BlackLight Power Inc. (BLP) has announced the successful independent replication and validation of its 1,000 watt and 50,000 watt reactors based on its proprietary new clean energy technology based on a new physics model of a hydrogen atom state they have dubbed the "hydrino".BLP's 50,000 watt reactor generated over 1 million joules of energy in a precise measurement made by Rowan University engineers, led by Dr. Peter Jansson. The independent study included full characterization of a proprietary solid fuel to generate the energy before and after the reaction.This new process could allegedly generate electricity for as cheap as 1 cent/kw-hour — two to four times cheaper than any other contemporary power sources. On May 28, 2008, the company announced that they have a 50 kW prototype ready to take commercial. The present development validates that prototype."

Submission + - Supercar Offering "Several Years Between Charg (

sterlingda writes: "Shelby Super Cars (SSC) holds the world's record for speed for a production car via their Ultimate Aero which has a twin turbo V-8 that produces 1,183 horsepower, housed in a lightweight, aerodynamic body. Reminiscent of Tesla Motors, Inc, SSC is pursuing a 500 HP electric vehicle based on SSC's world record design, with the expectation that the EV will become the fastest in the world. The difference? According to a company press release, "The drive train under development will feature a revolutionary power source allowing for extended time between charging intervals with the possibility of several years between charging." This implies that the motor is harnessing a tremendous amount of environmental energy on-the-fly. The company is being very tight-lipped about this energy source. SSC expects to roll out the first prototype of this green vehicle in February 2009."

Submission + - $150k Scorpion to Integrate Hydrogen Boosting (

sterlingda writes: "Until Scorpion, the hydrogen boost approach has been largely a movement of garage tinkerers and do-it-yourselfers, who have build a near infinite variety of on-board electrolysis units which duct the hydroxy (HHO) gas into the air intake, to catalyze a more efficient burn of the fuel, improving mileage from 20% on the conservative end, to near doubling of the mileage according to some not-so-scientific banter that floats around the net. There are also a few commercial operations producing and selling various hydrogen boost devices for retrofitting existing vehicles. Now Ronn Motors will be integrating an on-board electrolysis unit by Hydrorunner into its $150,000 Scorpion, expected to be released at the end of 2008 or early 2009. The system involves a 1.5 gallon tank for water electrolysis. Ronn Motors is working on being able to fill the tank with condensation from the air conditioning system, which will allow it to replenish itself. The hydrogen is just serving as a catalyst for the fuel, it is not the primary fuel source."

Submission + - 5,000 x Sunlight Thermal Record Set by SHEC Labs (

sterlingda writes: "SHEC Labs of Saskatoon, SK, Canada, claims to have the most efficient solar thermal technology in the world. By focusing the concentrated rays into the aperture of a highly-reflective, elongated tube, by the time the light bounces back out, it has gradually dumped 95% of its heat into the tube, which can then be put to work. The company expects that their commercial versions will be able to achieve concentration levels of 11,000 to 16,000 times the intensity of the sun. One of the applications of the technology will be in generating hydrogen and syngas from landfill methane. A pilot plant in Regina, SK Canada is expected to be completed in 2008; and a larger plant is being installed in Texas, which could fuel 5,000 vehicles per year. Another application of the heat will be to run a stirling engine or a steam turbine. SHEC Labs says they are in process of rolling out the capacity to produce three gigawatts, spread across six plans of 500 MW each, beginning overseas this year. A 5-15 year return on investment is expected at present fossil fuel prices."

Submission + - BlackLight's Hydrino Going Commercial (

sterlingda writes: "BlackLight Power Inc. announced Wednesday the successful testing of a new energy source. The company has successfully developed a prototype power system generating 50,000 watts of thermal power on demand. The BlackLight Process is a novel chemical process causing the latent energy stored in the hydrogen atom to be released as a new primary energy source. This allows the negatively charged electron that is otherwise in a stable orbit to move closer to the naturally attracting, positively charged nucleus to release large amounts of cheap, non-polluting heat that could replace the thermal power in coal, oil, gas and nuclear power plants that is then converted to electricity. Slashdot has covered Blacklight several times in the past."

Submission + - Wireless Headset Causes Fire in Microwave (

sterlingda writes: "Retired University of Colorado professor, Teresa Audesirk, reports seeing flames shoot out of an open plastic container in her microwave as she approached the microwave while wearing a wireless headset. Concurrently, the headset, which was a battery-powered cordless TV sound amplifier, went to a static sound. When she backed away from the microwave, the effect subsided. Then, as she approached again, the flames shot back out of the container that had green beans and salted water inside. Doing some checking around subsequently, she thinks that the phenomenon could be related to that reported by John Kanzius, who discovered an effect in which salt water burns when it is exposed to certain shortwave radio frequencies."

Submission + - Gravity-Powered LED Floor Lamp (

sterlingda writes: "A Virginia Tech student has created an LED floor lamp that is powered by gravity, using a weight slide similar to the concept of a grandfather clock. The lamp puts out the equivalent of a 40-Watt bulb, and lasts four hours per cycle. The mechanism is expected to last 200 years. The LED lamp, named Gravia, has just won second place in the Greener Gadgets Design Competition as part of the Greener Gadgets Conference in New York City."

Submission + - Transmission of Grid Power Using Pressurized Air (

Sterling D. Allan writes: "Instead of transmitting electricity over high-voltage cables, inventor, Thomas Kasmer, suggests transmitting power via high-pressure air, which would be pressurized and depressurized via his infinitely variable pneumatic conversion technology, which would serve as the transformers in the system. He thinks the transmission efficiency would be comparable, but the primary advantage would be the reduction of EMF and other hazards from high voltage transmission."

Submission + - All-Magnet Motor Demo -- by Steorn Observers (

sterlingda writes: "Back in July of 2005, Steorn embarrassed themselves by hosting a world-viewing demo of what was supposed to be a free energy device that defies the laws of physics. Unfortunately, their demo was botched. Meanwhile, a couple of Steorn forum members have been kicking around ideas for how to build an all-magnet motor with no other motive force. One of them shot a video showing acceleration of the device, but he doesn't seem to realize what he's accomplished. After the operator gives it a kick start, and gets the secondary counter-rotating magnet in sync, the motor accelerates to 1700 rpm, while the secondary magnet is spinning at 4200 rpms. When the operator holds two of the three secondary magnets (which are apparently interfering) stationary, the assembly accelerates further (secondary goes to around 5,000 rpm, as measured by an optical tachometer)."

Submission + - Microwave Converts Waste to Fuel (

sterlingda writes: "Global Resource Corp's High-Frequency Attenuating Wave Kinetics (HAWK) recycler extracts oil and gas in seconds from most everyday objects like tires, plastic cups, as well as from shale, coal, and tar sands. Microwaves tuned to an optimum frequency separate the component parts which can be burned or condensed into liquid fuel, using only a small portion of the energy produced."
