Rules:

-- PLEASE KEEP POST TITLES INFORMATIVE --

-- Overly editorialized titles, particularly if they link to opinion pieces, may get your post removed. --

-- All posts must include a link to their source. Screenshots are fine IF you include the link in the post body. --

-- If you are citing a twitter post as news please include not just the twitter.com in your links but also nitter.net (or another Nitter instance). There is also a Firefox extension that can redirect Twitter links to a Nitter instance: https://addons.mozilla.org/en-US/firefox/addon/libredirect/ or archive them as you would any other reactionary source using e.g. https://archive.today . Twitter screenshots still need to be sourced or they will be removed --

-- Mass tagging comm moderators across multiple posts like a broken markov chain bot will result in a comm ban--

-- Repeated consecutive posting of reactionary sources, fake news, misleading / outdated news, false alarms over ghoul deaths, and/or shitposts will result in a comm ban.--

-- Neglecting to use content warnings or NSFW when dealing with disturbing content will be removed until in compliance. Users who are consecutively reported due to failing to use content warnings or NSFW tags when commenting on or posting disturbing content will result in the user being banned. --

-- Using April 1st as an excuse to post fake headlines, like the resurrection of Kissinger while he is still fortunately dead, will result in the poster being thrown in the gamer gulag and be sentenced to play and beat trashy mobile games like 'Raid: Shadow Legends' in order to be rehabilitated back into general society. --

  • 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

also about a decade ahead in reactor technology

really? I thought that was actually the one area theyre doing well in. Or do you mean jet reactors or nuclear reactors?

nuclear reactors... what kind is the US ahead in?

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.
