Touch Screens
Interesting article, on the dubious benefits of touch screens. Who they're benefiting is debatable?

Electric Corvette
Source: http://www.hybridcars.com/genovation-cars-announces-gxe-performance-car-debut-2018-ces/
Instead of a rasping V8 however, Genovation removed all the engine bits and replaced them with a twin-motor electric powertrain and a 60 Kilowatt-hours (kWh) battery pack....
Genovation says the GXE accelerates to 60 mph in less than 3 seconds and top speed now exceeds 220 mph. Battery and powertrain in the car that sounds like a jet airplane when running at speed is said to have been derived from Le Mans and Formula 1 technology.
The startup expects the GXE to have 130 miles of range. Unstated is what type of charging system is on board or recharge times. Also expect that range to suffer under extreme usage at a racetrack. The original prototype with 44-kWh battery had been designed to be capable of two full-tilt laps at the 12.9-mile Nurburgring. -
Variable sized magnets in motors

Effectively, the tabs will allow the stacks to accept either short or long magnets–the tab will support the shorter magnet halfway down the aperture or get pushed out of the way upon inserting a longer magnet. GM claims there will be at least a 25-percent difference in magnet lengths.

What this means is a common motor core whose expensive, permanent magnets can be sized for the vehicle. This increases the commonality of parts to reduce manufacturing costs yet right-size the motor(s) to the vehicle.
