This is a place to share greentexts and witness the confounding life of Anon. If you're new to the Greentext community, think of it as a sort of zoo with Anon as the main attraction.

Be warned:

If you find yourself getting angry (or god forbid, agreeing) with something Anon has said, you might be doing it wrong.

Some solar panels on top of the balloon, nowadays you can even create your H on the go from the H2O in the air!

You don't use up the hydrogen in operation, so you don't need to create it on the vehicle. Attempting to do so would just add weight and probably wouldn't work anyway as I suspect the amount of energy you would require to convert water into hydrogen is a lot more than a few solar panels could ever provide.

The issue is hydrogen is just inherently dangerous. Compounded by the fact that no one really cares anyway because airships don't have a purpose to exist in the modern world outside of a very few niche scenarios.
