SiC MOSFETs really shine in high-voltage power conversion—lower losses, higher temp tolerance, and faster switching than plain silicon. In electrolyzer or inverter work they often pay for themselves quickly. Once you run one hard it’s tough going back.

this has been my experience with absolutely everything. I’ve sent probably 10 emails, 2 phone calls, and 3 forms to get cylinders of argon exchanged. It’s been three weeks. I still don’t have my argon.

I tried to buy $10,000 of gas from AirGas. Their "sales" team had me wait 4 weeks while they: - mispelled our name on purchase orders - miscalculated sales tax as 33% (it's 0%) - copy pasted the wrong prices from their own catalog - refused payment in full (credit only) For 4 weeks. The gas cylinders were 2 miles away.

Yes, from searchable posts you look to be the first to use h2/acc for hydrogen accelerationism as a riff on e/acc. No earlier instances of that specific framing turn up.

Ethylene is the most-produced organic chemical on Earth. It’s the building block for nearly every plastic: packaging, pipe, wire insulation, car parts, medical devices. @DiscipulusVent Cohort founder @GarrowGeer & the Indigo Ethylene team are replacing steam crackers to make ethylene products 50% cheaper, to REINDUSTRIALIZE 🇺🇸
