>I saw a comment on HN about how airships would be better if scaled up, and we should build a 1km long Hydrogen lift airship with carbon fibre and kevlar. Airships got a bad reputation because of the Hindenburg. Besides a few airships, they basically havent been touched in 75 years. Materials science has greatly improved since then. A modern take on an airship should be super effective. The thing is... they arent as fast as an airplane but boy can they ever lift. You could move heavy goods across continents for practically no cost. Personally I think Toyota's bonehead move to get into hydrogen cars was just a mistake. They could produce hydrogen based airships with their tech and become a giant.
