I have been thinking about something like this, but I thought it would be
easyest to use a spring loaded plug at the front of the robot, when the gass
explodes in the chamber in forces the remaining water and gasses out the
back. the force of the bot moveing forwaurd would push the spring plug back
and let water in, then the bot could repeat the prosses.
Well Bye bye

remember correctly, the procedure involves bombarding lithium with alpha
particles. The output antimatter is quite brief, I think, as it quickly
anhiliates with surrounding real matter.
Fusion reactions require tremendous amount of energy for initiation. Stars
use their immense gravity. Our own thermonuclear deviecs require nothing
less than fission reactions to generate the needed heat. That's
practically all a hydorgen bomb is: a fission bomb, encased within
deuterium and tritium (hydrogen isotopes). The fission bomb goes off, THEN
the hydrogen fuses, and adios muchahos.
What if, instead of a nasty fission reaction trigger, we could use just
a tiny portion of anti-hydrogen to trigger a controlled fusion reaction
inside a cloud of hydrogen plasma? Radioactivity would be drastically
minimzed in the absence of fission materials, and the antimatter
requirement would me miniscule; the fusion reactions could be designed to
sustain itself.
There's always the matter of containg the plasma, and stuff like that. But
I'm always curious as to what we could do with fusion, using the
technology we have now.
