The Download, Feb 21, 2017: DIY Autonomous Cars, Quantum Computer Duel, and a Real Hover Bike

The most fascinating and important news in technology and innovation delivered straight to your inbox, every day.

Three Things You Need to Know Today

The Rise of DIY Autonomous Cars
If a Tesla's too expensive, why not fit self-driving capabilities to your own car. Our own Tom Simonite reports that some people are starting to use off-the-shelf components and open source software to imbue their vehicles with Autopilot-like features. The mods are based on plans made available by autonomy start-up Comma.ai, which released code after its technology, intended for sale, was questioned by the National Highway Traffic Safety Administration. There appears to be little stopping consumers from making such tweaks to their vehicles—other than their own limits on personal safety.

Quantum Computers Go Head-to-Head
A quantum computer duel signals that the technology is maturing. Devices made by researchers from IBM and the University of Maryland in College Park using different approaches have been challenged to run a set of algorithms head-to-head—the former was faster, the latter more reliable. In the past, quantum computers have been pitted against regular hardware, rather than quantum rivals. As Sciencenotes, the new results are less exciting than their symbolism, as the ability to perform such a test suggests that quantum computing is coming of age.

An Audacious Climate Science Cruise
To understand the impact of global warming, get a ship stuck in ice. A team of climate scientists has a brave new plan: sail the 120 meter-long Polarstern research ship into the sea-ice of the East Siberian Sea, where it will become embedded and be slowly drawn across the Arctic, passing right over the North Pole. Along the way, researchers will perform experiments—analyzing water, ice, air, and weather—to understand more about the region's rapidly changing conditions. The voyage is scheduled for 2019.
