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.

MagKey uses magnets to stop keys jangling

Occasionally an invention comes along that promises to change mankind fundamentally, enable us to grow as a species, and expand our capabilities beyond what was previously thought possible. MagKey isn't one of those kinds of inventions at all. It simply uses magnets to stop keys from jangling, but we're still impressed.Read More

IBM sets new tape storage record

For many people, tape memory is a dead technology found only on reel-to-reel computers in old 1960s movies. However, it’s still a major storage medium and a new breakthrough by IBM Research and Fuji Film has produced a low-cost particulate magnetic tape with a record density of 123 billion bits of uncompressed data per square inch, which represents 88 times more capacity than 2012's LTO-6 tape cartridge.Read More
