Letters are well-known as designators. Consider Henry Ford and
the
Model T, for example.
This lighter will have a plastic double-wall "Dewar flask" case,
and the
fuel is solid hydrogen. Its shape is cylindrical, skinny, and
short. A
supercapacitor and some other electronics provides
a spark at
the
push of a button. Said button-push also mechanically extrudes
the
solid hydrogen, to be ignited. The fuel container needs to be
refilled, and the supercapacitor needs to be recharged,
after each use. But definitely weighs rather less than most
other
lighters, partly because the vacuum in-between the plastic
walls weighs nothing, partly because solid hydrogen is one of
the lightest substances around, and partly because the overall
device is smallish.

As delightfully complicated as this thing is, I hate to quibble. But ... |

Hydrogen flame is near invisible. Anybody using this is going to be
wondering if it is working, and won't be sure where the flame is.
Maybe some glowing metal guides? |

Also, the title kind of precludes charcoal lighters, and Sterno lighters.
Can you put an "H" in the title? |
