Hi M, Re: Hydrogen fueled aircraft....................

The problem isn't with the technology to use hydrogen to create motive power. The problem comes from creating a source of hydrogen that isn't impacting the environment to a worse degree than a carbon based fuel itself.

Sources of hydrogen are either hydrocarbon based or electrolysis based. Hydrocarbon based systems for generation hydrogen are endothermic (they use more energy than they create) and therefore not practical and also liberate CO². Electrolysis is just plain energy intensive no matter what the source.

It's tough to bypass the laws of thermodynamics!

Best wishes,
