1·1 month agoThis will continue as long as there are CCGTs used as baseload, then it will drop as CCGTs (and biomass + waste burners) will cover the gaps

4·1 month agomethane cracker? that’s a very unusual unit that outputs hydrogen and carbon. i could find info about opening of ethane cracker in 2025, but that’s for plastics, next to shutdown of another similar unit

News@lemmy.world•Trump orders Pentagon to redesign US aircraft carrier to use steam catapults to launch jets
1·1 month agoNo they don’t, there’s still 4 units one per launcher. Most of problems you mention seems to come from energy storage system. Energy is stored in the flywheels, which requires annoying converter, so chinese variant uses giant set of supercapacitors instead which is just a bit heavier and has less problems with communications interference. Also can be split in many parts and fit in any space you have. Mostly benefit of being designed later. Zero surprises if americans figure it’s better but institutional inertia keeps them using the old one

News@lemmy.world•Trump orders Pentagon to redesign US aircraft carrier to use steam catapults to launch jets
2·1 month agoThey don’t actually. Steam catapult is operated with completely separate steam supply, and major design goal of ford class was to remove it so even if pedo in chief wanted, retrofit is physically impossible. That separate steam supply needs extra freshwater because it’s not condensed and recovered. EMALS is much milder on plane and pilot because it’s a big linear motor that gives constant acceleration instead of spike then decreasing like with steam. Efficiency of steam catapult is also dogshit compared to turbine + energy storage system

who is “we”? as of now, there’s still oil being extracted and fertilizer being produced, just a bit less of it. if you live in a western country you don’t have to worry too much about it, except higher prices of food and everything that gets transported. if you’re a subsistence farmer in a place like bangladesh then you’re to some degree fucked
