H-Bomb question

The hydrogen bomb is a fusion device triggered by the a-bomb.
The isotopes of hydrogen-deuterium and/or tritium-fuse to release
exrodinary amounts of explosive energy.

Are the hydrogen isotopes a cryogenic liquid, or a room temperature compound?

In the early weapons, a room-temperature gas was used:

That goes for hydrogen fusion bombs. Other elements can be used, such as the light metal lithium. Lithium, being a metal, is quite solid at room temperature/pressure.

This do it yourself H-bomb uses lithium hydride or lithium deuteride as the fusion fuel. Hydrogen is much easier to deal with in solid form than as a liquid or gas. Plus, at high enough temperatures Li + D -> 2D + a whole bunch of energy.

Squink, that link is pretty funny, while being fairly accurate (as far as I know). My favorite quote:

Hee, Hee :stuck_out_tongue:

Hey, don’t laugh too soon. The accident at Tokaimura, Japan a couple of years ago (3 deaths) happened precisely for that reason.

Is it possible to build a fusion device using helium-3 instead of tritium? I was thinking along the lines of a bomb that wasn’t dependent on short-lived isotopes, and could be “shelved” for an indefinitely long time.

Fusing helium produces a much smaller mass-defect, so I’m not at all convinced that helium would even be suitable, much less efficient.
