Technology@lemmy.world•Americium: How a small element could power the next century of space explorationEnglish
2·26 days agoGood point on the lubricants, but given the potential profits, it’s already being worked on. https://www.nyelubricants.com/space

2·26 days ago10 times as much as gold
To -make-, yep. As the article pointed out, there’s a lot of Amercium in waste dumps where old smoke detectors … and anyone can make it. Five times the half-life means it can power much longer missions.

1·1 month agoGoing by ‘colour’, I’d guess that headline came from the UK. Writing them is a tricky, trippy task.

10·1 month agoYep, I noticed that, you’re right. And that’s near-miraculous efficiency. The maker’s website sez: “YASA also estimates that its all-important continuous power will be in the region of 350kW-400kW (469bhp-536bhp).” It also sez: "To achieve a 750kW short-term peak rating and a density of 59kW/kg … " Devi’ls in the details … The image on the ‘superblondie’ page shows A LOT of cooling built into whatever metal that is: https://supercarblondie.com/wp-content/uploads/YASA-tiny-electric-motor.webp

61·1 month agoIt was a decent summary, I was replying when you pulled it. Analog has its strengths (the first computers were analog, but electronics was much cruder 70 years ago) and it is def. a better fit for neural nets. Bound to happen.

41·1 month agoNice thorough commentary. The LiveScience article did a better job of describing it for people with no background in this stuff.
The original computers were analog. They were fast, but electronics was -so crude- at the time, it had to evolve a lot … and has in the last half-century.








Sooo… you’re looking for volunteers to join your discord … no website to learn more … and get involved with … who, where, what, why completely unknown … to ‘collaborate remotely’ to ‘foster critical thinking’ … with little mention of what ‘volunteers’ will get in return … that’s all a very vague come-on inviting complete strangers to cooperate with you … an completely unknown organization, no mention of your qualifications, no mention of who’s paying for this (podcasting is not free) or why … that is SO NOT TEMPTING
