i'm sorry i can't hear you over my 90% fusion neutron capture

anyone else kinda excite about this?

>energy requirements to make "target" plasma toroid are well below what the tokamak uses
>compression requirements to initiate and sustain an even fusion burn of the target have already been demonstrated at ITER
>time requirements for fusion events are well within what's already been done
>this is practically already proven

there will be annoying gremlins. every fusion method has them, hopefully it's something easy like uneven compression, which can easily be compensated for by high speed computers synchronizing the firing of the pistons, or purposefully setting them out of sync to "shape" the compression wave

>only requires very brief plasma confinement, way less time than MCF has already achieved.
>compression will easily achieve plasma density necessary for fusion
>lead/lithium mixture completely absorbs the emitted energy, both heat and neutrons
>lithium converts into your fuel
>motherfucking steam powered pistons to boot.
>sphere will weigh something like 20 tons
>prototype reactor built by general fusion firing some time this year

why are you not excited?

Combines magnetic confinement and internal confinement and captures the energy and neutrons released.

Magnetized target fusion sounds almost too good to be true.

Scaled down magnetized target fusion reactor!

If a more promising reactor isn't conceptualized in the next 10 years, this is exactly what I'll be working to achieve.

hey mang, i have pretty high hopes for MTF

Nuclear engineering, fusion R&D
Save our souls

>>4992357
Not if fusion and I have something to do with it.

MTF looks cool
7/10 would fund

oftentimes easier said than done. lots of equipment. lots of maintenance, lots of cost

/sci/....i think i want to build one.
how does the NRC feel about fusion? or tritium breeding?

of course anything i could would probably be a linear implosion system on a centrifuge, just a proof of concept for fun. making a full sized thing with all the required pitons would be....quite expensive..

you should probably be paying attention to this, /sci/
it looks fantastic on paper, and a cobbled together model was about one order of magnitude away from the target plasma pressures, which is fantastic.

bonus points for the fact that the compacting liquid lead acts as a perfect neutron shield (no embrittlement or containment loss issues), and captures basically 100% of the neutron energy to convert into heat

this canadian upstart called general fusion is building a full sized prototype testbed reactor, it should begin firing next year

looks almost as good as LFTR, except this doesn't have as many hurdles in terms of reprocessing efficiency as LFTR has

here's something cool;
magnetized target fusion

http://en.wikipedia.org/wiki/Magnetized_target_fusion

the general idea is that you get a big sphere, and fill it with a lead/lithium mixture.
inject the lead/lithium from the equatorial section, and withdraw it from the poles.
this causes a spinning action within the liquid. make the spinning powerful enough, and you'll open up a small cylindrical cavity in the liquid at the very center of the sphere.
now, inject some hot tritium/deuterium plasma into that central cavity (pre-heat it using magnets before doing so), magnets around the sphere keep the plasma in place and compressed, but not for very long.
as soon as the plasma is injected, you THUNK! the sphere, and thus the liquid, with powerful pistons from all directions.
this causes a traveling shockwave within the liquid, which travels all the way to the core cavity (where the plasma is waiting)
as the shockwave converges, it compresses the plasma to a superdense state, causing it to undergo fusion from the pressure.
the fusion reaction release heat, and a SHIT TON of neutrons. the lead blanket captures the neutrons and heats up in the process. because the lead is so freakishly dense, it captures ALL the energy from ALL the neutrons of the reaction, perfect capture efficiency (that's REALLY GOOD).
the neutrons also convert some of the lithium into tritium (which is your fuel).
