This week on Expanded Perspectives the guys start the show out talking about how if you step into a taxi in south London later this year and you might not have to think about paying a tip. The UK’s first fully public trial of autonomous vehicles will soon be under way. For four weeks, a fleet of driverless shuttles will each ferry up to five passengers and a “safety warden” along a 2-kilometre route in Greenwich. Previous trials there and in the town of Milton Keynes required participants to register in advance. This time the vehicles will pick up anyone wanting a ride. The four-stop route will connect a hotel close to the O2 Arena concert venue with the Millennium Village housing development. En route, the shuttles will also call at a river-bus stop and a cable car terminal. Then, University of Washington researchers have invented a cellphone that requires no batteries—a major leap forward in moving beyond chargers, cords and dying phones. Instead, the phone harvests the few microwatts of power it requires from either ambient radio signals or light. Then, a resident of the Weikert, PA area a friend were on a designated hiking trail in the Bald Eagle State Park when they heard something walking to their right in the woods as if following them. It turned out to not be a bear. What it was, was far more frightening. Then, in a tiny, remote Aboriginal community in outback Australia, an American linguist discovered that a new language emerged among the young people in the community and is now spoken by around 350 individuals, all under the age of 35. But how was this new language spawned when they were already perfectly able to communicate with each other without it? After the break Kyle brings up some incredible encounters with multiple UFOs during the Vietnam War. Some even attacked both American and NVA soldiers. All of this and more on this weeks installment of Expanded Perspectives!
