Directorly Downwind Faster than the Wind

[Cloxxki]

Clo you have a wonderful imagination Bud![the rail thing would be cool]
but whats the BB bit?

Black Bird is the new name of the DDWFTTW cart of the American team.

Now that is very cool!!

And these fellows are close by[less than an hour]
definitely looking into this when things slow down at the boat yard.[see if they have gone to manufacture?]

Funny I was looking in to building a bow thruster blade[prop],hence the "carrots".
maybe I'll play in the wind also![HHMMmm. if it works in the wind ,it should work in the water?]
Fixed blades!![nothing moves but the bearing]
Very cool !!

PS Clo
Thanks on th BB

Well,
The thing about wind is it can be fickle,comes and goes,sometimes to much sometimes to little.

My car however................

TS ,
can this be possible?
Could we build a "forevercar"?

I bet the boys in Mass. would help us with that one!
What do you say fellas??

I'll go see them ,But only if we will work together "open source"!

Forevercar would be an interesting challenge.

I propose a special rail track be build for this, roughly a triangle shape, to keep it interesting.
Batteries on board to ensure >0 speeds in low winds, albeit very reduced speeds (low rolling resistance is key here). Flat ground, of course.
Car only goes full speed when batteries are fully charged.

I have some advanced ideas for collapsible airfoils and even propellors. Transformer robot style. More to boost speed than to ensure non-stopness.

Once the thing runs well on wind power alone, batteries may prove the limiting factor, or perhaps reason is found to add solar cells for extrqa speed during daylight.
Properly engineered, I would not be too surprised if a non-stop 60mph could be achieved, with a payload of several persons.

A sailboat may already be able to do this, with some batteries, turbines, and solar panels. How long can a drought of wind be, a few weeks? And boats have the added opportunity to make use of streams and tides to extract energy from the ocean.

How would the self-vortexing rimmed turbines do in propellor mode DDWFTTW, for the same diameter as the Black Bird's prop?

Clo
I want to drive !!
A "forever"!
Cadillac had a motor that dropped 2-4 cylinders out at speed,because once you get to speed it requires less effert to stay there.

This little "4 times more efficient " turbine/vortex gizzmo just might make enough power at speed to run "forever".
That would be enough "overunity" for me!!
And no voodoo.......... ,nice wholesome wind![a rushing mighty wind even......]

A little test bed should prove sufficient !??

Any ideas ?
Lets build something!!
