I knew it was good… but I had no idea: How much antimatter is needed to heat 1 T of H2 from cryogenic liquid to 4000 K? About 300 micrograms. 1200 T of H2 requires 360 milligrams of antimatter. If that antimatter is cryogenically frozen solid antihydrogen, it occupies about 4 mL. Somewhat less than…
OceanX is one of the wind turbines that has been making a lot of noise lately as it is now the world’s largest single-capacity floating wind platform.

While the on-chip memory has been upped to 520KB – there is also 4 MB of on-board QSPI flash – the two RISC-V Hazard3 CPU cores included in the microcontroller may well interest…

Driving China’s ascendancy is a massive and abrupt shift to electric vehicles. The EV share of total car sales will jump to almost 50% this year, up from…
