Thought-provoking feature, Enrique. Perhaps, we should collaborate on further pieces? I published an article about this subject matter on Medium in 2020 (https://medium.com/predict/why-russias-latest-cargo-airship-project-is-not-just-hot-air-d25190024573).

I suggest governments that are serious about protecting the environment for future generations should financially support the cost and research into manufacturing viable airships for cargo.
