Elon Musk, the entrepreneur behind the launch of PayPal, Tesla and SpaceX, has lifted the covers off the Hyperloop, a new transport concept linking Los Angeles and San Francisco that could hurtle passengers through a tube around the US at near-supersonic speeds.
Musk envisions using magnets and fans to shoot capsules floating on a cushion of air through a long tube.
Should the Hyperloop be ever built, a trip on it between the two cities would take around 30 minutes.
The highest speed recorded by a train on a national rail network (rather than a dedicated test track) is 574.8 km/h (357.2 mi/h), by a French SNCF modified version of the TGV on 3 April 2007. The peak speed was achieved between the Meuse and Champagne-Ardenne stations on the LGV Est high-speed rail line in eastern France. FACT: The line has cut journey times between Beijing and Tianjin from 70 minutes to 30 minutes.
Although not officially announced by developers Rockstar, gamers have been given the clearest indication yet that Grand Theft Auto 5 will also be coming to PC this year.
The news comes from a somewhat unlikely source - Chris Evenden, senior IR director at graphics card manufacturers Nvidia.
While the much anticipated game has long been confirmed for release in September on Xbox 360 and PS3, Rockstar have been tight lipped about it getting a release for Windows systems.
Speaking at the company's most recent earnings call, Evenden put Rockstar's next open-world gangster opus as among the top games coming to PC later this year.
With more than 106 million copies of Grand Theft Auto games sold from its 1997 debut to August 2012, the GTA videogame series holds the Guinness World Records title for best-selling action-adventure videogame series.
Set for release in 2015, the film is set in the mind of an 11-year-old girl called Riley, with the characters representing different emotions inside her brain.
Actors lending their voices to the film include Amy Poehler, Mindy Kaling, Bill Hader, Lewis Black and Phyllis Smith.
