Highlights from the 2014 LA Auto Show

Transmission

A means of powering electric vehicles using radio frequency transmission has been demonstr...

Two issues preventing the widespread uptake of electric vehicles are recharging time and lack of range. Now, scientists have shown one potential means of negating these issues. Their demonstration of electric power transfer via the car-wheel is claimed as the world's first.  Read More

The Efneo gearbox is claimed to be equivalent to a front crankset equipped with 28t/40t/50...

While shifts between the sprockets on a bike's cassette are generally quite fast and crisp, going between the chainrings up front is definitely a slower, more awkward affair. In an effort to make things quicker and easier, Poland's Efneo has developed a 3-speed planetary gearbox to take the place of the front derailleur.  Read More

Gregory Zielinski with his Nuseti prototype

Much as mountain bike technology has advanced since the days of friction shifting and elastomer shocks, most MTBs are still equipped with dangling, fragile rear derailleurs and dirty chains. Switching to a belt drive or a hub transmission are a couple of options, but Polish mountain biking medalist Gregory Zielinski has created another. His Nuseti bike features what he calls the Inner Drive System (IDS) – a 16-speed planetary gearbox that's incorporated into the bottom bracket, and a chain that's enclosed within the frame.  Read More

Volkswagen has been working on a new 10 speed dual-clutch autobox (DSG)

How many gears are too many for the average commuter vehicle? If you’re pulling a load of cattle across Saskatchewan, then a semi-tractor unit with nine gears should suffice. But if you’re Volkswagen, then the magic number for your upcoming models is in fact 10.  Read More

The Synchrobox has an integrated front derailleur, and mounts at the bottom of the seat tu...

Judging by the increasing popularity of 1x11 drivetrains and hub transmissions, a lot of cyclists are evidently getting tired of shifting between multiple chainrings. Indeed, it can get confusing trying to figure out if your gearing needs are best met by shifting to a bigger ring in front, a smaller sprocket in back, or what. IXOW's new Synchrobox is designed to address that conundrum – it uses one shifter to automatically adjust both derailleurs, in order to attain the rider's desired gear ratio.  Read More

The Cavalerie Anakin enduro bike

Dirty, noisy chains and dirty, fragile rear derailleurs are two features of modern mountain bikes that could certainly stand to be made obsolete. Well, the Cavalerie line of full-suspension MTBs does away with both, replacing them with a Gates Carbon belt drive and an Effigear gearbox. Launched last year in its native France, Cavalerie is about to get a boost in profile, as it commences distribution in North America.  Read More

Artemis has unveiled pCell, a new mobile network technology that overcomes the problems as...

The rise of smartphones and subsequent explosion in mobile data usage has put a strain on mobile networks, slowing them down when congested and requiring more and more radio spectrum space to accommodate the demand. Artemis Networks hopes to solve this problem with a new technology called pCell, which promises full speed mobile data regardless of the number of users.  Read More

WRX in its native environment, sliding around a corner on a dirt road

The Subaru WRX has always been a touchstone for rally car performance in a street legal car with its fast handling, turbocharged acceleration and hefty hood scoops. Subaru's long-awaited refresh adds a six speed manual or automatic gearbox, new styling, and bids farewell to the five door hatchback version.  Read More

Artist's concept of the LLCD transmitting to Earth (Image: NASA)

This week, NASA released the results of its Lunar Laser Communication Demonstration’s (LLCD) 30-day test carried out by its Lunar Atmosphere and Dust Environment Explorer (LADEE) that is currently in orbit around the Moon. According to the space agency, the LLCD mission proved that laser communications are practical at a distance of a quarter of a million miles and that such a system could perform as well, if not better, than any NASA radio system.  Read More

New York City in the pastel shades of Nickolay Lamm's cellular network interpretations (Ph...

Nickolay Lamm is a self-identified artist and researcher, who is making a career of transforming ordinary images into extraordinary visual displays of quantitative information, to borrow from Ed Tufte. We take a look at his transformation of New York, Chicago, Hollywood, and Washington D.C. through converting cellular network transmissions into visual overlays.  Read More
