But the Alliance of Automobile Manufacturers expressed concern that California was moving too quickly to embrace self-driving cars and needed to first sort out liability issues
Autonomous cars can make roads safer, free commuters from the drudgery of driving, reduce congestion and provide transport to people who can't drive themselves, such as the blind, disabled, elderly and intoxicated,
Autonomous cars use computers, sensors and other technology to operate independently, but a human driver can override the autopilot function and take control of the vehicle at any time.
McKinsey & Company analyzed energy use by data centers and found that, on average, they were using only 6 percent to 12 percent of the electricity powering their servers to perform computations. The rest was essentially used to keep servers idling and ready in case of a surge in activity that could slow or crash their operations.
To guard against a power failure, they further rely on banks of generators that emit diesel exhaust.
Even running electricity at full throttle has not been enough to satisfy the industry. In addition to generators, most large data centers contain banks of huge, spinning flywheels or thousands of lead-acid batteries — many of them similar to automobile batteries
A device using the technology would use built-in accelerometers to detect when a user puts it down, and would then log its owner off to keep unauthorized people from getting in
requires new software and biometric sensors built into consumer devices, but does not require the development of any new kinds of chips
