The Hank Roberts stove really was advanced for its day, so advanced in fact that it still stacks up pretty well against today's stoves. When almost everybody else was using piercable canisters that couldn't be removed until empty, the HR stove had a detachable canister that could be removed, and the HR stove could completely outperform other gas stoves of the day because it was a liquid feed stove. In cold weather, the HR stove to this day will still outperform modern upright canister stoves, including things like the $150 MSR Reactor!
