I don't know why the Hindenberg's solution to carrying varying loads does not get more traction in the press. The Hindenberg was a hybrid. It had the ability to heat it's internal gas, and thus could get lift both from the gas it carried as well is the same effect as a hot air balloon. This effect is not fast enough to, say, pick up huge loads, but it did solve the problem of needing to vent gas to stabilize its weight due to passengers and other loads, along with a water ballast system.
