Just found this old thread.Reviewing the Positron Dynamics videos, I see nothing about kaons and muons. I see that mentioned on this Next Big Future article:http://www.nextbigfuture.com/2016/10/positron-dynamics-vision-of-antimatter.htmlBut that doesn't correspond with what's shown even the screenshots that they link. I have to wonder if that's their own speculation.
And more to the point, if the whole goal is to set off fusion reactions with gamma, why not just have gamma emitters onboard instead of going through the whole positron generation / moderation process? Handling difficulties? They could start with parent isotopes that decay to gamma emitters, so they wouldn't be so hazardous in the beginning...
I didn't want to start another thread for this but i found an old article on the casimir effect possibly being of use for repelling or levitating certain materials and wondered if this could be tinkered with to make better antimatter storage?https://phys.org/news/2012-04-prospects-quantum-levitation.html#nRlvAnd speaking of casimir force there was this on my feeds this morning:https://phys.org/news/2017-04-harness-mysterious-casimir-tiny-devices.htmlWoohoo!
using positron annihilation for propulsion is fairly sketchy compared to antiprotons anyway but one old school idea was using the released energies and light to heat another medium that is used for exhaust either through ablation of something like tungsten or using the heated tungsten or whatever to heat a working medium. This new method seems to bypass a lot of those steps in the Rube Goldberg style of the older positron schemes.
what link or reference tells me how thrust is produced?
