Magnetic fridge eliminates gases, drastically reduces energy use

The days of the rackety, energy-gobbling refrigerator may be numbered with the advent of more efficient systems that cool with the use of magnets. The idea has been around almost as long as your standard gas-compression fridge, but it hasn't yet been viable for the household and commercial markets. Now, Cooltech Applications has launched the first magnetic refrigeration system (MRS) for commercial use.Read More

Magnetic beads effectively "patch" bowel leakage

Whether you call the condition fecal incontinence or accidental bowel leakage, it still boils down to the same thing – the unintentional loss of stool, due to a damaged or weakened anal sphincter muscle. While non-invasive approaches such as physical therapy can work, sometimes the only course of action is to perform a colostomy. That said, Torax Medical has developed another option, in the form of its FENIX Continence Restoration System. The Mayo Clinic in Jacksonville, Florida recently became the first US clinic to implant the device.Read More

Reusable microbots make meal of toxic metals

Researchers have developed a tube-shaped microbot that offers a cheaper and more effective way of removing heavy metals than previous methods. The self-propelled microbots use an outer layer of graphene that binds to lead ions it comes in contact with. The scientists found that they can remove 95 percent of lead from polluted water in one hour, and once they have a full payload, they can be cleaned and reused multiple times.Read More

Robot climbs up pipes to clean power station boiler tube walls

Cleaning power station boiler tube walls is a dirty and troublesome job that is not only hazardous, but can generally only be done during station down times to minimize the risk to human cleaners. To help address this problem, a new robot has been developed that is specifically designed to climb and clean boiler tube walls, even in confined spaces and at elevated particulate levels.Read More

Review: MagLOCK magnetic pedals should attract a certain crowd

Many mountain bikers swear by the pedalling efficiency of so-called clipless pedals, in which a steel cleat on the bottom of each shoe engages a spring-loaded mechanism in the pedal. Some other riders, however, just don't like the idea of being "snapped in" like that. It was with this in mind that cyclist Dave Williams created MagLOCK pedals. They're non-threatening platform pedals, that keep the user's feet in place using magnets instead of mechanisms. We recently had a chance to try them out, and generally liked what they had to offer.Read More

SnapFlask makes any bike bottle magnetic

We've already seen magnets and clips used in products that allow cyclists to do away with their frame-mounted water bottle cage. The problem with both systems is that they require users to stick with a brand-specific bottle. With Torq Athletic Gear's new SnapFlask, however, riders can use any bottle they want.Read More

Material that could revolutionize memory storage is magnetic, but not as we know it

Using a type of magnetic insulator material that normally doesn’t conduct electricity, scientists working at Stanford University and the Department of Energy’s SLAC National Accelerator Laboratory have shown that electric currents can still be made to flow along the borders of the grains within the material. This latest research not only validates a long-held belief that magnetic insulators could be used to conduct electricity, but offers a more tantalizing possibility of creating highly-efficient magnetic memory devices.

Magnetism generated in non-magnetic metals

By subtly altering certain quantum interactions in matter, scientists from the University of Leeds have shown for the very first time how to generate magnetism in metals that aren’t normally magnetic. Synthetic magnets made using this technique may one day reduce our reliance on rare or toxic metals in such things as wind turbines, computer hard drives and magnetic field medical imaging devices.
