A university in Singapore has conducted one of the first practical flights of a solar-powered quadcopter drone.

The prototype has flown as high as 10 meters (about 33 feet) in test flights using solar power with no battery or other energy storage on board, according to the National University of Singapore (NUS), which announced that an engineering team had conducted the test flight.

“Rotary winged aircraft are significantly less efficient at generating lift compared to their fixed wing counterparts [so] a viable 100 per cent solar rotary aircraft that can take-off and land vertically remains a major engineering challenge to date,” the university said in a statement.

Rural communities in Japan are facing a labor shortage as farmers age and young people move to urban areas. The drones, which fly over fields quickly performing tasks strenuous to farmers, may be one part of how farms in the aging rural heartland can adapt.

The country isn’t a world leader in autonomous or electric vehicles, but it’s all in on putting cars in the sky.

The news: Japan announced today that it’s bringing together 21 companies and organizations, including big hitters like Uber, Boeing, Airbus, Cartivator, and Japan Airlines, to bring aerial vehicles to the skies within 10 years.

The challenge: The government said it will address one of the major things holding back flying cars: regulation. “The Japanese government will provide appropriate support to help realize the concept of flying cars, such as creation of acceptable rules,” the ministry said. If Japan is able to quickly establish a legal system in which flying cars can function, it could get a jump start over countries like the US, whose Federal Aviation Association has been notoriously slow-moving on things like drone regulation.

The US Congress wants the Missile Defense Agency (MDA) to rapidly develop and demonstrate a boost-phase ICBM (and hypersonic weapon) intercept capability as soon as practicable.

Space-based laser weapons technology is one of the options.

Yuneec’s Mantis Q is a foldable drone that features 4K, voice controls, face detection, and 33 minutes of battery life. It’s available for preorder now.

The nearly successful drone assassination attempt on Venezuelan President Nicolas Maduro earlier this month highlighted yet again a persistent worry for U.S. defense planners: the possibility that a swarm of cheap drone-borne bombs might overwhelm the sophisticated defenses a U.S. base or ship. While the defense industry has seized upon this concern and is currently at work developing new high-tech solutions to this problem, the Department of Defense can’t rely on those alone. It makes sense to develop such solutions, but the Department of Defense procurement process is long and the threat is now. With a little ingenuity, there is much that can be done with existing technology to defend effectively against drone threats. Accordingly, this article focuses on the measures the Department of Defense can employ now, with existing technology, to mitigate the threat of drone swarms.

The Current Problem

The drone swarm threat to U.S. naval installations and ships is already quite serious. Only a small amount of explosives and shrapnel would be required to cause significant damage to many of the most important radars, cameras, and important flight systems on ships, missiles, and aircraft. Damaging critical equipment would put military platforms out of action for several weeks or even months and put intense pressure on naval logistics chains and maintenance organizations at a time when they are already hard pressed to keep up with current demands. Even more importantly, such an attack orchestrated on a grand scale could leave U.S. forces unable to respond to critical events around the world in sufficient time to fulfill U.S. defense commitments to allies and friends.

While Facebook and Google recently pulled the plug on their solar-powered internet drones, another company with a lot more experience is having success with the idea. Airbus announced that its solar-powered Zephyr S HAPS (high altitude pseudo-satellite) flew for 25 straight days, setting a time aloft record for any airplane, ever. It shattered the previous record of 14 days, marked by a previous prototype Zephyr aircraft.

The Zephyr flies on sun power alone at over 70,000 feet, an altitude that just a few aircraft like the Concorde and SR-71 Blackbird have reached. That’s well above any weather, and lets it perform reconnaissance, surveillance and communications/internet duties. “[It fills a] capability gap complimentary to satellites, UAVs and manned aircraft to provide persistent local satellite-like services,” Airbus said in a press release. A video of the takeoff (below) shows that it can be lifted and launched by hand. Once aloft, it can be operated for a fraction the cost of a satellite.

A research expedition to a huge underwater canyon off the Irish coast has shed light on a hidden process that sucks the greenhouse gas carbon dioxide (CO₂) out of the atmosphere.

Researchers led by a team from the University College Cork (UCC) took an underwater research drone by boat out to Porcupine Bank Canyon — a massive, cliff-walled underwater trench where Ireland’s continental shelf ends — to build a detailed map of its boundaries and interior. Along the way, the researchers reported in a statement, they noted a process at the edge of the canyon that pulls CO₂ from the atmosphere and buries it deep under the sea.

All around the rim of the canyon live cold-water corals, which thrive on dead plankton raining down from the ocean surface. Those tiny, surface-dwelling plankton build their bodies out of carbon extracted from CO₂ in the air. Then, when they die, the coral on the seafloor consume them and build their bodies out of the same carbon. Over time, as the coral die and the cliff faces shift and crumble, which sends the coral falling deep into the canyon. There, the carbon pretty much stays put for long periods.
