Thousands of people die every year due to drunk driving. It’s a statistic that’s both appalling and frightening. We all like to party, but then when the party’s over, many still refuse to recognize the danger they not only put themselves in, but others as well when they choose to drive while mentally impaired. Thankfully a lot of potential situations are averted every year as well due to taxi services, or even friends willing to drive them home.
Today, however, we live in a very sensor-oriented society. Our phones have sensors. Our homes have sensors. Our tablets have sensors. Our cars have sensors. Take Tesla Motors as an example. They have sensors by their doors which detects whether or not the right driver is approaching the vehicle. If it detects its correct driver, then it’ll extrude the door handle out, ready to be open. If you’re not the correct driver, however, like someone trying to hijack the vehicle, then the door handle will not pop out for you. Sorry.
Another good example is the Mercedes-Benz, which has driving sensors attached to its braking system. If any object in front gets too close, then the brakes kick in automatically, preventing any accident from occurring. Too many fatalities occur due to simple, brief loss of eye contact to the road.
Good news, future space travelers: Now you can enter the void without bringing your wallet.
U.K. business magnate Richard Branson announced Friday that his commercial space travel venture, Virgin Galactic, will allow customers to pay for their flights with the digital currency Bitcoin.
“Virgin Galactic is a company looking into the future, so is Bitcoin. So it makes sense we would offer Bitcoin as a way to pay for your journey to space.” Branson wrote in a blog post.
“A lot of the people who have joined Bitcoin are tech-minded people, as are many of our current future astronauts.”
A researcher envisions the ultimate cure for “range anxiety”: roadway-powered vehicles with modified on-board power receivers.
One way to extend the range of electric vehicles may be to provide power wirelessly through coils placed under the surface of a road. But charging moving vehicles with high-power wireless chargers below them is complex.
Researchers at North Carolina State University have developed a way to deliver power to moving vehicles using simple electronic components, rather than the expensive power electronics or complex sensors previously employed. The system uses a specialized receiver that induces a burst of power only when a vehicle passes over a wireless transmitter. Initial models indicate that placing charging coils in 10 percent of a roadway would extend the driving range of an EV from about 60 miles to 300 miles, says Srdjan Lukic, an assistant professor of electrical engineering at NCSU.
Wireless charging through magnetic induction—the same type typically used for electric toothbrushes—is being pursued by a number of companies for consumer electronics and electric vehicles (see “Wireless Charging—Has the Time Finally Arrived?”). Such chargers work by sending current through a coil, which produces a magnetic field. When a car with its own coil is placed above the transmitter, the magnetic field induces a flow of power that charges the batteries.
