Researchers at MIT have come up with a de-icing system that is completely passive and relies only on the power of the sun, or artificial light, which means it can also work at night. The system could be used to prevent ice building up on aircraft wings, wind turbine blades, and powerlines.

Drivers considering plug-in hybrid vehicles with a gasoline backup are most interested in economic benefits while those gravitating toward battery-electric vehicles have stronger environmental concerns, according to a study led by a University of Kansas transportation policy scholar.
The research has identified distinct profiles of people considering newer electric vehicle technologies showing the two types of vehicles—one that offers gasoline as a safety net and another that relies solely on battery charging—are very different in the eyes of consumers.
“Our findings inform the misconception and show that electric vehicles are not a homogeneous entity,” said the study’s lead author Bradley Lane, associate professor in the KU School of Public Affairs & Administration. “There are distinctive profiles of potential users for whom a plug-in hybrid is attractive and another for whom a battery electric is attractive. And these are two very distinct groups, similar to how there is a group of users who are attracted to a sport-utility vehicle and a separate group attracted to an economy car. We have shed more light on what factors influence how people make these decisions.”
A team of young Japanese engineers is developing a flying car with the goal of launching it in time for the 2020 Tokyo Olympics.
The futuristic vehicle – dubbed Skydrive – is fitted with three wheels, a motor and four rotors, enabling it to take off and land vertically from public roads without the need of a runway.
Measuring only 9.5 feet by 4.3 feet, Skydrive claims to be the world’s smallest flying car, with a target top flight speed of 62 mph, while travelling up to 32 feet above the ground.
Tesla’s Semi truck has already made some city-to-city trips, but how does it fare on cross-country jaunts — you know, what it’ll be doing when it enters service? Just fine, if you ask Elon Musk. In response to an Electrek piece on the Semi’s latest visit (to Arkansas trucking behemoth J.B. Hunt), the CEO noted that the Semi has been traveling thousands of miles entirely by itself, using the existing Supercharger network. The only necessary help is an “extension cord” to help the truck plug in. To be exact, it’s a system of cords that plugs into multiple stations at once to top up the Semi’s giant battery before the company’s Megachargers come online.
That solo travel is likely meant in part to reassure customers (including J.B. Hunt) that the Semi is already capable of handling long-distance trips without escorts. However, it does leave a few open questions. How long does it take to top up using Superchargers, and how likely is it that drivers could rely on them when Megachargers aren’t available? While it’s easy for a Tesla-operated truck to cross the US using the existing framework, it’d be another matter with thousands of third-party trucks in service. This is a significant step toward the Semi hitting the road in earnest, but there are many more steps to go.
What’s cool is that it was driven across the country alone (no escort or any accompanying vehicles), using the existing Tesla Supercharger network and an extension cord— Elon Musk (@elonmusk) August 25, 2018
Alphabet’s self-driving car subsidiary, Waymo, has kicked off speculation about its ambitions for the Chinese market by creating a small outpost in Shanghai.
What’s it mean?: If Waymo is aiming to break into China, then this would be a very preliminary step. The new office might also be something less exciting: a means of working with Chinese hardware suppliers for instance.
Auto revolution: T hat said, it would make a lot of sense for Waymo to target China. It is the world’s largest auto market and a hotbed of technology and market innovation. And while Google’s plans to re-enter the Chinese market have proven controversial, the truth is that China cannot be ignored by any tech company that wants to a global force.
Packing more energy into batteries is the key to delivering electric cars with longer range, smartphones that can last days—and cheaper electronic products all around.
The promise: Lithium-oxygen batteries represent one of the more promising paths toward that end. They could boost energy density by an order of magnitude above conventional lithium-ion batteries—in theory, at least. In a paper published today in Science, researchers at the University of Waterloo identified ways of addressing some of the major hurdles to converting that potential into commercial reality.
The challenge: A critical problem has been that as a lithium-oxygen battery discharges, oxygen is converted into superoxide and then lithium peroxide, reactive compounds that corrode the battery’s components over time. That, in turn, limits its recharging ability—and any real-world utility.
The facial recognition technology the US is testing for airports has caught its first imposter merely three days after Washington Dulles International started using it. According to US Customs and Border Protection (CBP), a 26-year-old man from Sao Paulo, Brazil successfully fooled people with a French passport until he presented it to a Dulles officer who used the new facial comparison biometric technology. The system determined that his face wasn’t a match with the person in the passport, and he was sent for a comprehensive check, which revealed the Republic of Congo ID hidden inside his shoe.
