It is not negotiable or conditional.” That doesn’t sound like a deal. Biden, according to the readout, “ welcomes a separate discussion with congressional leaders about how to reduce the deficit and control the national debt while continuing to grow the economy.”  A clean hike in the federal borrowing limit first, Republican policy priorities later.

The reusable air defence system that could protect China from hypersonic weapons

  The reusable air defence system that could protect China from hypersonic weapons The device produced more than 10 times the power generated in previous experiments, they said in a paper published in the peer-reviewed Chinese Journal of Theoretical and Applied Mechanics on January 19. The generator system works by setting off explosions that turn gas into fast-moving plasma. It then converts the plasma’s energy into high-power electricity. In one experiment, the system generated high-energy shock waves through a hydrogen-oxygen explosion. The shock waves compressed Argon gas and accelerated it to Mach 14, or 14 times the speed of sound, turning the inert gas into a highly conductive plasma full of hot, electrically charged ions.
