Yacht holds its own

While we imagine of the world’s mega-yachts out in the open ocean, they are largely dependent on the land to refuel and resupply. The UNA autonomous yacht explores how one might be self-sufficient to the extent that it could remain at sea for extended periods of time if not a lifetime. Using photoelectrochemical hydrogen procution, the boat can produce its own fuel and maintain power indefinitely. As for food and water… well… you’d better like seafood!

    You should run your numbers. An ocean going yacht will burn a few thousand dollars of fuel a DAY. So this amount of energy is not going be replaced by a couple of solar panels the size that you have here. Dream on.

  • Graham Kukla says:

    While the boat is strictly conceptual at this point in time, there are advancements being made every day on photoelectrochemical (PEC) hydrogen production, bringing down the cost and using more abundant materials to do so. The idea behind the powerplant is that it could produce its own hydrogen, powering a generator, producing electricity for the IPS drives. The Solar panels, and ability to collect tidal energy, are supplementary sources of power.

    As for food and Water, there is a two story vertical hydroponic garden on the ship, as well as a small desalination plant.

    The concept is really an exploration of how mega yachts can become centers of production, rather than just consumption.

    apply same type engine to other yachts
    Mass produce & lisc to other yacht makers

    Hi Graham,

    If that really is the point of this design, then show how this energy is produced – Not just consumed. Choosing one of the most extravagant forms of transport is hardly a sound platform for a conservation design.
    Luxury yachts do not have the clientele to hand over yacht acreage to farming, or waiting until the hydrogen tanks are filled.
    While there are certainly advancements being made in solar energy (PEC et al), these will only reduce the current efficiency rates. Even having 100% efficient system will still not allow THOSE panels to move THAT ship. There is just not enough power in sunlight.
    Try again, starting with a sailboat.

    Well just from a chefs point of view, the amount of food you would need to grow for just the crew would be close to 2 tonnes a week, and that’s just fresh fruit and veg. I don’t see it!!! However, that doesn’t mean I wouldn’t be the first person to apply for the job, just to see if it can be done.

    Absolutely beautiful design work there, what a cracking looking yacht. I’ll pin that first image on pinterest, thanks.

  • This open space provides a well-lit gathering spot for entertaining.
    However, screws should be countersunk and covered to
    create a neat exterior appearance. In point of fact, you happen to be informed not to paying for any cooking area redecorating yourself.
