EVTOL battery analysis reveals unique operating demands. Researchers at the Department of Energy’s Oak Ridge National Laboratory are taking cleaner transportation to the skies by creating and evaluating new batteries for airborne electric vehicles that take off and land vertically.

These aircraft, commonly called eVTOLs, range from delivery drones to urban air taxis. They are designed to rise into the air like a helicopter and fly using wing-borne lift like an airplane. Compared with helicopters, eVTOLs generally use more rotors spinning at a lower speed, making them both safer and quieter.

The airborne EV’s aren’t just flying cars, and ORNL researchers conclude that eVTOL batteries can’t just be adapted from electric car batteries. So far that has been the dominant approach to the technology, which is mostly in the modeling stage. ORNL researchers took a different tack by evaluating how lithium-ion batteries fare under extremely high power draw.

DoorDash and Wing (an Alphabet company) have announced their first joint drone delivery service in the United States. Targeted at select customers in Christiansburg, Virginia, eligible DoorDash orders from Wendy’s can now be delivered via Wing drone.

Wendy’s orders will be delivered using a Wing drone, which can travel up to 65 mph. Upon reaching its destination, the drone will lower the order to the doorstep using a tether.

Tesla continues to make progress on its upcoming diner, drive-in theater and Supercharger in Los Angeles, with recent drone footage showing new water runoff infrastructure, preparations for stucco installation on the first-floor walls, and seemingly, materials for the start of some interior construction.

In a drone video update shared by YouTube channel 247Tesla on Sunday, you can see new stacks of sheetrock both inside and outside of entrances to the Tesla diner building, as construction prepares to begin focus on interiors. The video also shows a new rectangular area dug roughly five feet deep into the ground, which the video’s host says will likely be used to control water runoff.

FCC cracks down on retailers like Amazon allegedly selling illegal signal jammers. Investigations are underway.

Uh-oh, Amazon. Looks like the Federal Communications Commission (FCC) is not playing around when it comes to selling illegal signal jammers. The agency just went public with an investigation into Amazon and other major retailers for allegedly pushing these dodgy devices that can block your cell signal, GPS, and more.

Typically advertised as “drone deterrents” or “privacy tools”, these nefarious gadgets are specifically designed to block radio frequencies. This has serious ramifications, cutting off cellular devices and GPS units and impacting emergency communication channels.

“The challenge is getting into those hidden places,” says Machado. “It’s rare that Aedes aegypti breeding areas are found out in the open, like on a sidewalk, because when people see them, they destroy them. But with drones, we can get into areas we just can’t otherwise.”

Birdview has carried out studies with several partners since 2021, including the United Nations, the University of São Paulo (USP), and the state-owned Brazilian Agricultural Research Corporation (Embrapa), to better understand the effectiveness of releasing the disease-fighting mosquitoes with drones. First they looked at how the mechanism of the drone and outside conditions, like wind turbulence, affected the survival rate of the mosquitoes and their ability to fly.

The results were positive, so they moved on to flight-and-release tests in the Brazilian states of Pernambuco and Paraná, as well as Florida, where they’ve been working with the Lee County Mosquito Control District to see how far the mosquitoes spread upon release. They used the “mark, release and recapture” method, which involves sterile male mosquitoes being marked with a certain color before being released and later recaptured with traps so the team could see how far they had flown. They also set traps where eggs could be laid and monitored.

Researchers claim to have combined the benefits of rolling robots with those of flying drones by creating a device that rotates along the ground but hops over obstacles.

Tesla is making construction progress on its upcoming lithium refinery in Texas, as shown in photos taken by one drone pilot this week.

Longtime Tesla construction observer Joe Tegtmeyer shared photos of Tesla’s forthcoming lithium plant near Corpus Christi, Texas, on Monday. The photos, as posted on X, show the foundations of what will eventually be Production Line 1, with other superstructure work and the beginnings of construction on Production Line 2, as Tegtmeyer explains.

Construction on the lithium plant was well underway by August, though Tegtmeyer’s latest photos show that the site has come a long way since then. He also points out that a new electrical substation has appeared at the site, while the installation of Rotating Kiln and Cooler Set 1 equipment has mostly been completed.

The show on Tuesday night was an abstract light show partially designed with AI.

Lt solution for ht problem.

The Ukrainians recently captured a Russian drone which communicates via a fiber-optic link, making it jam-proof. This looks like a big headache and not just for Ukraine.
