      Although the linked article is for a boat propellor, there is very little difference in principle between a propellor and a fan, both achieve their objectives by sucking in a fluid on one side and spitting it out on the other. Although pitch angles may need to be adjusted for the fluid’s viscosity, this novel design promises higher efficiency (i.e. less noise and power) while shovelling out more fluid than a conventional design. It will be interesting to see if theGPU manufacturers pick up on this one!

        Thats real interesting. I can only assume that it some how concentrates the water and then pushes against it at the same time. Which is a bit odd as that sounds kinda quantum.

        But yeah the lad invented it 10 years prior to getting it to production.

        Does look like a total winner.Obvs boats ships consume stupid amounts of fuel. Put one of these on a nuke sub and we could end up with the fictional flying sub being real. aka 70’s vogue to the bottom of the sea. Not!

        Erm, yeah I remember when I was 12 and got my first box of Lego technics I invented a gear less gear box. A device that achieved the same out come as a gear box but with no gears. I was told that some one must have already made it. But in the day of the electric car gears are close to a thing of the past. I see to compete with electric cars the hyper-car makers are now using a gear box where every gear has its own clutch. LOL.

        Check out this nubile goofy professor on where we are now with the electric car. The conclusion is an eye opener.

          Simplistically the propellor scoops up the fluid from one side, holds it in place then uses the centrifugal force of the rotating prop to fling it out of the other side. The neat part of the design imo is the way the prop actually scoops up the fluid and holds it in place ready to eject.
