„Technologija yra sunki, o masinio pristatymo ekonomika gali niekada neturėti prasmės.Kodėl dronai tokie sunkūs naudojime?
Per daug žadanti ir nepakankamai įgyvendinama
"The technology is hard and the economics of mass deliveries may never make sense.
Jeff Bezos said Amazon drones would be bringing toothpaste and cat food to Americans’ homes within four or five years. That was nearly nine years ago. Oops.
This week, Amazon said it planned to start its first drone deliveries in the U.S. sometime in 2022, maybe, in one town in California.
The typical technologists’ approach is to think smaller, which means confining drones to relatively uncomplicated settings. The start-up Zipline focused on using drones to deliver blood and medical supplies to health care centers in relatively spread-out parts of Rwanda and Ghana where driving was difficult. A typical suburb or city is more complex, and vehicle deliveries are better alternatives. (Lockeford, Calif., where Amazon plans its first U.S. drone deliveries, has a few thousand people living in mostly spread-out households.)
That’s still an incredible achievement, and over time drones are becoming more capable of making deliveries in other types of settings.
Overpromising and underdelivering
The parallels between drones and driverless cars kept jumping out at me. Drone technologists told me that, as with driverless cars, they misjudged the challenge and overestimated the potential for computer-piloted vehicles.
We keep making the same mistakes with automated technology. For decades, technologists kept saying that driverless cars, computers that reason like humans and robotic factory workers would soon be ubiquitous and better than what came before. We want to believe them. And when the vision doesn’t pan out, disappointment sets in."
"A critical piece of pipeline equipment was sent to Canada for repairs. Its return has been held up by sanctions against Russia.
Gazprom, the Russian gas monopoly, said on Twitter on Tuesday that it was reducing the amount of gas it sends to Germany via the Nord Stream pipeline by about 40 percent because a turbine sent for repairs had not been returned “in due time.” It said it could not provide the amount of gas normally sent to Germany without the machine.
Adding further upward pressure to prices, a major liquefied natural gas export facility in Texas, called Freeport LNG, said Tuesday that it would require 90 days, much longer than initially expected, before even returning to partial operations after a fire last Wednesday. In recent months, Freeport LNG has been a large exporter of natural gas to Europe and elsewhere, helping to ease a supply crunch.
And in a tweet on Tuesday, the German ministry responsible for energy said the security of natural gas supplies was “unchanged guaranteed.”
