The Zhejiang Geely Holding Group recently unveiled the prototype design of the Terrafugia TF-2A eVTOL aircraft, and announced that they have already begun flight tests as well. The newer design is a clear upgrade over the previous demonstrator that was revealed in December 2019.

Based on the aesthetics of a tiger shark, the TF-2A features a large upper wing, H-shaped tail, eight lift propellers for vertical takeoff or landing (VTOL) as well as one rear propeller for horizontal flight. According to Geely, the design should make certification easier to obtain as opposed to the more common tilt-rotor designs in the industry. For example, the New Hampshire Senate recently motioned to pass a number of bills, one of which pertained to the topic of aerial mobility. HB-1517, “An Act Relative to Roadable Aircraft,” adds the words “roadable aircraft” to existing laws for vehicles concerning things like inspections and crashes, requiring the roadable aircraft to be “required to take off and land from a suitable airstrip and shall be prohibited from taking off and landing from any public roadway, unless under conditions of an emergency”. Currently, only Terrafugia’s TF-2A and PAL-V’s eVTOL meet these standards.

A team of researchers simulated conditions on water-rich exoplanets in the laboratory and learned something surprising about their geological composition.

Out beyond our solar system, visible only as the smallest dot in space with even the most powerful telescopes, other worlds exist. Many of these worlds, astronomers have discovered, may be much larger than Earth and completely covered in water — basically ocean planets with no protruding land masses. What kind of life could develop on such a world? Could a habitat like this even support life?

A team of researchers led by Arizona State University (ASU) recently set out to investigate those questions. And since they couldn’t travel to distant exoplanets to take samples, they decided to recreate the conditions of those water worlds in the laboratory. In this case, that laboratory was the Advanced Photon Source (APS), a U.S. Department of Energy (DOE) Office of Science User Facility at the DOEs Argonne National Laboratory.

Chesky predicted that vacationers will stay closer to home in the future, largely limiting their travel to places within driving distance, with national parks becoming even more popular destinations.

“I think you’re going to start to see travel becoming more intimate, more local, to smaller communities,” he said, citing Airbnb data that shows travel within countries is recovering to normal levels. But its international business is still being hit hard. “People are not getting on airplanes, they’re not crossing borders, they’re not meaningfully traveling to cities, they’re not traveling for business.”
