High Temperature Superconducting Magnets Just Got 45% More Power - 0 views

  • Engineers at the National High Magnetic Field Laboratory at the Florida State University are closer than ever to launching a new generation of high-field magnet, being 3,000 times stronger than an ordinary refrigerator magnet and will be able to generate a field about 45% more powerful than the strongest superconducting magnet currently available. The new high tech magnet will be made of a high-temperature superconductor that is far less expensive to operate than its conventional counterparts and more energy efficient. According to the researchers, it could mark the beginning of a new generation of super powerful magnets that help lower both the carbon footprint and cost of scientific research.

Magnetic Particles of Gold, Silver and Copper Produced - 0 views

  • An international team led by Physics and Chemistry teams from the Faculty of Science and Technology at the University of the Basque Country (UPV/EHU) and directed by Professor Jose Javier Saiz Garitaonandia, has achieved, by means of a controlled chemical process, that atoms of gold, silver and copper - intrinsically non-magnetic (not attracted to a magnet) - become magnetic. The article has been published in the February issue of the prestigious international magazine in nanotechnology, Nanoletters (Vol.8, No. 2, 661-667 (2008).

University of Miami physicist develops battery using new source of energy - 0 views

  •  
    a battery that is "charged" by applying a large magnetic field to nano-magnets in a device called a magnetic tunnel junction (MTJ). The new technology is a step towards the creation of computer hard drives with no moving parts, which would be much faster, less expensive and use less energy than current ones. In the future, the new battery could be developed to power cars. The study will be published in an upcoming issue of Nature and is available in an online advance publication of the journal.

New compact sensorless AC drive from Parker gives 12% energy savings - 0 views

  • To date, permanent magnet motors have not been widely used in many industrial applications as they require additional speed or position sensing mechanisms and control by high end drive units, making them relatively costly and complicated to install.  As a result, even though they are less efficient and considerably larger in size, induction motors have generally been the preferred choice for design and production engineers. Now, however, by using innovative algorithm control based on motor voltage and current output, the new AC650S Drive enables standard permanent magnet motors to be used in closed loop applications, without the need for additional sensors.  Engineers can therefore benefit from the energy savings that can be achieved from brushless motor such as Parker’s NX and ATEX EX Series, with savings of up to 12% for a 0.75kW system being possible; similarly, engineers have the opportunity to design more compact control systems, which can be as small as 25% the size of a conventional induction motor assembly.

Harnessing Back EMF to create free energy? - 0 views

  • nventor who stumbled upon a way of making electric induction motors work, at the very least, more efficiently
  • . At most, he believes he's figured out a way to manipulate magnetic fields so that instead of slowing down a generator (according to Lenz's law in physics) it speeds it up. In fact, it gets caught in a positive feedback loop, resulting in a dramatic acceleration without any change to power input.
  •  
    Is this for real?
    would like some comments from other team members.
    apparently, there is some ground here, even if not many people can explain it. anyway, this could mean a good breakthrough on improving the efficiency of a motor, particularly big motors...

    I guess this one remains in the category 'harebrained' until proven otherwise.

Electrinium Battery Remains Un-replicated - 0 views

  • The device claim is that it can put out as much as 10,000 Volts of power per cubic inch of device.  Electrinium is said to be to electricity as magnets are to magnetism.  Talk about an ideal solution to the oil/energy Earth destruction paradigm!  Yet, in the numerous years that this author has known about this device, no one has reported even trying to build it, much less successful replication

Large-scale dimmer switch company gets $9 million | CNET News.com - 0 views

  •  
    Metrolight, which has just received $9 million in a third round of funding from Gemini Israel Funds and Richard Branson's Virgin Fuels, has been riding a surge of demand for its high-frequency electronic ballast, a device for controlling high-intensity discharge (HID) lights--those bright lights used for illuminating department stores, large interior spaces and freeways. The system effectively provides the same amount of light as more traditional magnetic or electromagnetic systems, but requires less overall power, the company says. Additionally, the HID lights can be dimmed when no one is present or, if the light fixture is connected to the Internet, dimmed by a utility to prevent a brown-out. Some customers have seen their electric lighting and maintenance bills drop by around 50 percent, according to Metrolight.

As China's Rare Earth R&D Becomes Ever More Rarefied, Others Tremble -- Stone 325 (5946... - 0 views

  • China was late to join the race to develop novel rare earth materials, elements that are essential constituents of everything from iPods to Patriot missiles. But Western observers agree that China is catching up fast in areas such as fuel cells and magnetic refrigeration. Today, about three-quarters of the world's neodymium magnets are made in China. Domestic industrial demand is rising: Last year, China consumed 60% of all processed rare earths. That unnerves some industry analysts and U.S. legislators, who have expressed concern about China's dominance of the rare earth supply. Last year, China satisfied 95% of global demand—now about 125,000 tons per year—and holds more than half of all proven reserves. In 2005, prices started creeping up when China began to limit production and slap export tariffs on some rare earths. In a policy paper last month, China's Ministry of Industry and Information Technology floated the idea of prohibiting export of three scarcer rare earths: europium, terbium, and dysprosium. If the Chinese government were to implement such a policy, it would be a big problem for other countries.

A more efficient electrical generator, or something much more profound? - 0 views

    In other words, Heins claims to have eliminated the magnetic friction and replaced it with magnetic acceleration. He calls this effect "regenerative acceleration," but those who are skeptical of his claims say that acceleration does not equate to power/torque/work and that Heins has failed to demonstrate there is such a link.

Space storm alert: 90 seconds from catastrophe - space - 23 March 2009 - New Scientist - 0 views

  •  
    Interesting article from New Science describing how a "coronal mass ejection" from the Sun could melt down the electrical power gird. ".... Over the last few decades, western civilisations have busily sown the seeds of their own destruction. Our modern way of life, with its reliance on technology, has unwittingly exposed us to an extraordinary danger: plasma balls spewed from the surface of the sun could wipe out our power grids, with catastrophic consequences..." The article does offer a solution: upgrade the ACE solar satellite, to detect an electro magnetic surge and provide power grid operators with about 15 minutes to shut down their systems. The article does not discuss another possible option: stop building centralized power sources that demand increasingly massive power grids. Instead, concentrate on meeting energy needs using localized sources of power; like the highly portable Hyperion Power Module.

    OSAKA, JAPAN- From the 22nd floor of the Nakanoshima Central Tower, the offices of Hisao Fukami, comes news of Toyota's newest patent as filed with the WIPO (World Intellectual Property Organization) International Bureau, and released for international publication July 17, 2008. The Fukami Patent Office is listed as the agent for Toyota, who applied for the patent and worldwide rights January 11, 2007. The motor is interesting in its use of an "externally applied light" to a light sensitive rotor kept in a "permanent magnetic state" to generate torque.

      This may be useful, but the emissions for trains are already low per passenger. It is just icing. We need to be investing in carbon capture and make all stations ready for the tech when it arrives.
