I wonder if warm water costs a lot less to run a seacrete accumulating electrode? 08:12 < docl> also of interest: https://en.wikipedia.org/wiki/Ion_exchange 08:18 -!- yashgaroth [~ffffffff@172.58.19.202] has joined ##hplusroadmap 09:43 -!- abetusk [~abe@68.175.128.91] has quit [Remote host closed the connection] 09:46 -!- justanotheruser [~justanoth@unaffiliated/justanotheruser] has quit [Quit: WeeChat 2.7.1] 09:47 -!- justanotheruser [~justanoth@unaffiliated/justanotheruser] has joined ##hplusroadmap 10:15 -!- delinquentme [~delinquen@c-73-15-72-140.hsd1.ca.comcast.net] has joined ##hplusroadmap 10:29 -!- HEx1 [~HEx@hexwab.plus.com] has quit [Remote host closed the connection] 10:30 -!- HEx1 [~HEx@hexwab.plus.com] has joined ##hplusroadmap 10:31 -!- HEx1 [~HEx@hexwab.plus.com] has quit [Remote host closed the connection] 10:48 -!- delinquentme [~delinquen@c-73-15-72-140.hsd1.ca.comcast.net] has quit [Quit: Leaving] 10:56 -!- HEx1 [~HEx@hexwab.plus.com] has joined ##hplusroadmap 11:26 -!- CryptoDavid [uid14990@gateway/web/irccloud.com/x-gtrjhzvhbfxvvess] has joined ##hplusroadmap 11:42 -!- ffranr_ [~ffranr@79-65-233-180.host.pobb.as13285.net] has quit [Ping timeout: 246 seconds] 12:23 -!- aeiousomething [~aeiousome@unaffiliated/aeiousomething] has quit [Quit: leaving] 13:16 -!- Codaraxis [~Codaraxis@ip68-5-90-227.oc.oc.cox.net] has quit [Remote host closed the connection] 13:17 -!- Codaraxis [~Codaraxis@ip68-5-90-227.oc.oc.cox.net] has joined ##hplusroadmap 15:43 -!- aeiousomething [~aeiousome@unaffiliated/aeiousomething] has joined ##hplusroadmap 16:56 -!- Urchin [~urchin@unaffiliated/urchin] has joined ##hplusroadmap 16:57 -!- justanotheruser [~justanoth@unaffiliated/justanotheruser] has quit [Ping timeout: 252 seconds] 17:00 -!- darsie [~kvirc@84-114-73-160.cable.dynamic.surfer.at] has quit [Ping timeout: 246 seconds] 17:26 -!- justanotheruser [~justanoth@unaffiliated/justanotheruser] has joined ##hplusroadmap 17:29 -!- ffranr_ [~ffranr@79-65-233-180.host.pobb.as13285.net] has joined ##hplusroadmap 18:36 -!- ffranr_ [~ffranr@79-65-233-180.host.pobb.as13285.net] has quit [Ping timeout: 264 seconds] 18:38 < kanzure> https://theconversation.com/from-coronavirus-tests-to-open-source-insulin-and-beyond-biohackers-are-showing-the-power-of-diy-science-138019 19:01 -!- justanotheruser [~justanoth@unaffiliated/justanotheruser] has quit [Ping timeout: 272 seconds] 19:02 -!- justanotheruser [~justanoth@unaffiliated/justanotheruser] has joined ##hplusroadmap 19:05 -!- soju [uid403160@gateway/web/irccloud.com/x-hevkxsdewzznqpza] has quit [Quit: Connection closed for inactivity] 20:50 -!- yashgaroth [~ffffffff@172.58.19.202] has quit [Quit: Leaving] 20:52 < lsneff> .t https://www.sciencedirect.com/science/article/pii/S0094576520303179 20:52 < saxo> Future interstellar rockets may use laser-induced annihilation reactions for relativistic drive - ScienceDirect 20:52 < lsneff> Uses Rydberg Matter, not sure if that's been confirmed yet. 20:58 < lsneff> They purport that it is roughly 100 times better than producing usable energy than fusion. 21:06 < fenn> i feel like the abstract is missing the word "antimatter" 21:07 < fenn> there are two claims being made here, 1) lasers can induce nuclear annihilation in hydrogen, and 2) it's useful for rockets 21:08 < fenn> claim 2 is relatively uninteresting 21:08 < lsneff> The first claim relies on using ultradense hydrogen, which is still purely theoretical I believe 21:09 < L29Ah> ultra dense hydrogen – COLD FUSION NOW! 21:09 < L29Ah> -- google 21:09 < lsneff> Basically 21:10 < fenn> whenever i read about particle physics my eyes glaze over 21:10 < superkuh> [4].
