  • After America abandoned development of its ‘dream shell’, Chinese scientists now claim they have managed to create it
  • The shell travels at Mach 7 while receiving satellite navigation signals and maintains an error margin of less than 15 metres (49 feet)

so lets run it back:

-the us failed to make a working hypersonic missile, china has a reliable domestic design.

-the us gave up on railguns, china is achieving breakthroughs and will likely create a working design some day.

-and now china again succeeded where the us quit.

damn the us navy is really struggling huh

Damn, US obviously needs to up their military funding so they can develop these things! No wonder they're falling behind with such a paltry military budget, how are they expected to be competitive when they only have ten times the budget of their enemies? They need at least 20 times, or 30 times! The US should just close down public schools or something to afford it, it's not like those kids need to learn to read anyway, who even reads in the US these days?

also about a decade ahead in reactor technology

The U.S. made a breakthrough battery discovery — then gave the technology to China

When a group of engineers and researchers gathered in a warehouse in Mukilteo, Wash., 10 years ago, they knew they were onto something big. They scrounged up tables and chairs, cleared out space in the parking lot for experiments and got to work.

They were building a battery — a vanadium redox flow battery — based on a design created by two dozen U.S. scientists at a government lab. The batteries were about the size of a refrigerator, held enough energy to power a house, and could be used for decades. The engineers pictured people plunking them down next to their air conditioners, attaching solar panels to them, and everyone living happily ever after off the grid.

"It was beyond promise," said Chris Howard, one of the engineers who worked there for a U.S. company called UniEnergy. "We were seeing it functioning as designed, as expected."

But that's not what happened. Instead of the batteries becoming the next great American success story, the warehouse is now shuttered and empty. All the employees who worked there were laid off. And more than 5,200 miles away, a Chinese company is hard at work making the batteries in Dalian, China.

The Chinese company didn't steal this technology. It was given to them — by the U.S. Department of Energy. First in 2017, as part of a sublicense, and later, in 2021, as part of a license transfer. An investigation by NPR and the Northwest News Network found the federal agency allowed the technology and jobs to move overseas, violating its own licensing rules while failing to intervene on behalf of U.S. workers in multiple instances.

Now, China has forged ahead, investing millions into the cutting-edge green technology that was supposed to help keep the U.S. and its economy out front.

UniEnergy Technologies sold a few batteries in the U.S., but not enough to meet its requirements [of selling a certain number of batteries to the US]. The ones it did sell, including in one instance to the U.S. Navy, were made in China.

That's a truly Polish moment.
