Commercial drones are being used to quickly scope out damage, map 3-D views of the flood zone and help with rescue efforts in the areas devastated by Hurricane Harvey.

Drone inspectors: Outside of disaster recovery, one of the fastest-growing uses for commercial drones is to inspect infrastructure, property and equipment. That's how companies and local government officials are putting drones to use, especially in badly flooded areas that are still too dangerous for people to venture into.

How drones are being used to assess damage:

  • AT&T is using drones to inspect cell towers for damage near Corpus Christi. Drones can provide a more detailed view of the sites than human cell tower climbers, and it can inspect more towers in less time, freeing up workers to make the most urgent repairs. The company told Axios it has deployed 46 drones so far, and has an additional 58 drones on standby.
  • Allstate Insurance will fly hundreds of drone missions a day to inspect property in what is probably is largest-scale use of the technology, as will USAA and Farmers Insurance, according to the San Antonio Express-News.
  • DroneDeploy, which makes software for drones to capture images while flying, plans to publicly share data collected by drones in the areas affected by Harvey so the community and rescue operations can zoom into 3-D maps to see around buildings and bayous and under trees, CEO Mike Winn told Axios. He estimates drones can work six times faster than humans trying to reach the scene.
  • The FAA has authorized oil and energy companies to look for damage to their facilities, fuel tanks, power lines and other parts of the local power grid.

Taking to the skies: The Federal Aviation Administration warned unauthorized drone operators to steer clear of emergency response operations. As of Thursday, the FAA said it has authorized 43 drone operators who are supporting the response or covering it as part of the media.

Lives saved: Drone enthusiasts also point out their life-saving potential. In a March report, drone maker DJI says drones have rescued at least 59 people from life-threatening conditions, by its count. More than one third of the people rescued were saved by drones operated by civilian bystanders and volunteers, according to the report.

Breaking down the Tesla obsession

Tesla is the company of the moment — the prime exemplar of just about any big and important trend that you might care about.

Why it matters: Almost every reader of finance and business news will have at least one strongly-held opinion about Tesla. What you might not realize is just how widely those opinions range, and the degree to which they map onto much broader views of the world.

Gallup: Party preference swings dramatically in favor of Democrats

Americans' political party preferences have swung sharply from a 2-point Republican advantage in January to an 11-point Democratic advantage in July, according to Gallup's monthly averages of telephone polls in 2020.

The big picture: The dramatic shift is more a product of fewer people identifying as Republican or Republican-leaning (down 8% since January) than gains among those who identify as Democratic or Democratic-leaning (up 5%).

Nancy Pelosi: "I yearn for other Republican presidents"

House Speaker Nancy Pelosi (D-Calif.) called on President Trump Thursday to exercise "the full power" of the Defense Production Act to meet coronavirus equipment needs and accused him of engaging in a "massive dereliction of duty" by ignoring science during the pandemic.

What she's saying: "I yearn for other Republican presidents," Pelosi said at a press conference. "While we may have disagreed on many points, but at least we had a shared commitment to the governance of our country."
