Camoesas, Worlds first Savonius turbine boat, 2007.

[S1ngula1rity]

I cannot see anything going wrong with this on a full sized working model.

Hello Carlos, really nice concept. Could you please tell the viewers the materials you used. I think I want to give a shot at trying to recreate a boat like this one...

It would be really appreciated...

I was confusing it with magnus effect. I couldn't find anything with a savonius rotor. Congrats

[andrewjlea]

@ anny141: The coolest thing about using the rotor's spin to drive an underwater propeller is that you can make successful forward "sailing" exactly into the eye of the wind...

This was done dacades ago BTW. Plenty of full size ships demo-ing these sails on youtube right now.

This has been done decades ago...

@andrewjlea

If so, would you please be so kind and post at least ONE link to ONE of those, made decades ago?

Do not confuse Savonius with Magnus effect!

Thanks and best regards,

Carlos Camoesas.

A better idea than gearing a savonius to a propeller might be to take the shaft straght down to a Voith cyclical drive. Eliminate transmission losses by keeping everything turning on the same axis, plus get tremendous manoueverability.

[PeterMarleenDaaf]

make the speed of your screw adjustable. When sailing 45 degrees into the wind, your rotor wil not be driven by the screw... ;-)

[HeavyDemir]

so does it sail ? I'd like a video of this out on the lake :)

These were first built in the 60s and 70s

If anyone likes this idea they should look up the movie "Waterworld" there is a seriously cool trimaran with a Vertical Turbine driving a prop. Unfortunately you'll have to put up with Kevin Cosner for 2 hours.

It runs against it with the wind, the turbine drives a collection of small sprockets/differential to a propeller under the water. Or atleast it should. If thise one doesn't then its not as good as the one i am designing.

[packagewarren]

i see no boat in water to prove that this idea works. 1 star.

[carmatic]

why dont you rig the turbine to drive a propeller? that way when you are facing against the wind, the turbine spins faster and the propeller drives harder

[DominickBlack]

It's a really good idea,

[TheSmokingNug]

the problem with this model of savonius boat is the drag created near the waters surface. id recommend starting the savonius further up the pole and not have it close to touching the boat. very cool though.

[WulfBand]

It would be so simple to put a gear on the bottom and attach a propeller shaft to the bottom.

FREE POWER :)

GREAT IDEA

[LightningRose]

I'd like to see how it does in the water.

I recently came up with the same idea myself, but without experimentation I've concluded a catamaran or trimaran would be necessary for stability in crosswinds.

[ChrisOHenning]

Please show us how it runs on water.

[slymjim2007]

that is absolutely wild. Love it
