    Thanks for the links schakel! That hydrogen plant project is very ambitious. Very glad to see the Netherlands forging ahead in this area. Many will be monitoring its progress.

    I recall the city of Denver, Colorado did a feasibility study several years ago. They discovered they gave enough wind blowing through that city that:
    1. The wind generators will generate excess hydrogen.

    2. The amount of hydrogen will power a hydrogen car for every family in the city.

    Wind power can play a key role.

    That is not enough of a wing to be effective.
    More an eyecatcher rather than an honest effort to improve efficiency.

    You might as well fly hydrogen filled balloons to decrease hydrodynamic resistance.

    It's just a concept. The real wing is on the drawing board at Van Peteghem Laurent Prevoist.
    And I like your fairy tale imagination.

    H2 fuel-cell for propulsion don't seem to be practical. H2 may have energy, but fuel cell is the bottleneck, can't convert that energy fast enough for meaningful power. Not to mention all the more weights to add the more power to output. Sail & wind power must be much more green than fuel-cells so far as propulsion is concerned. But it should be good tech to replace batteries. A green boat to me would be a sailboat with solar and hydro-gen; and the surplus electric power will be stored up as H2, no more batteries. H2 fuel-cell can supply electricity when needed. Which means the boat will still need an engine & burn fossil fuel when no wind or too much wind. But that's probably as low carbon as can practically be there. Or actually, propulsion by H2 combustion might be a more plausible alternative. I wonder if this can be done with rotary engine design? Be something I'd test if have that kind of money.

    This design is so simple I reckon if the chambers be made with ceramic (or may not be necessary) might just work.

    Won't that shadow the solar cells?

    Yes, but like all things, there are tradeoffs. That boat is considered a power plant. If you can generate more propulsion with the wind, then you do so. If your solar production is not keeping its minimum; you'd be forced to reef the sails.

    It is really no different than having a few days of lousy solar production on a power boat and needing to run the engines, but sort of the opposite. If they have good solar production, then they can hoist the sails.

    Pretty interesting.

    True, it's a matter of choice, in windy conditions, sailing prevails.
    How do you feel about the wing sail configuration;
    Isn't it the hoistable version of the hard wings during AC 35?
