New drone designs enable small UAVs to conserve battery life by taking breaks in unusual locations as opposed to landing back on the ground.
For example, engineers from Yale University and their colleagues demonstrated novel landing gear for drones to perch like birds or hang like a bat. From Smithsonian
“We have a few different perching strategies,” says Yale researcher Kaiyu Hang, lead author of a study recently published in Science Robotics. “Where it is totally perched, where it is grasping around something, like a bat, we can stop all the rotors and the energy consumption would become zero.”
Another option is what Hang calls “resting.” It involves using a landing device that enables a drone to balance on the edge of a surface, such as a box or a ledge. In that position, it would be able to shut down two of its four rotors, cutting consumption roughly in half. Another alternative makes it possible for a drone to sit on top of a small surface, such as a pole, a tactic that cuts energy use by about 70 percent, according to Hang.

Trump says Google wants to rig the 2020 election.
Amazon, Apple, Facebook, and Google (Alphabet) will testify next week before a House congressional committee at a hearing on the power held by online platforms, and whether government should be regulating it.
GrubHub is buying up thousands of restaurant web addresses, and “also appears to publish shadow pages without owners’ consent—sometimes in direct competition with real websites,” reports The New Food Economy. Why would the app-based restaurant delivery service do such a crazy thing? It looks like the reason may be — shocking, I know! — predatory […]
