Well, here is a video shot from behind the driver.

http://www.youtube.com/user/TraderTurok#p/u/2/39LhFo3P-bw

Too bad they are on this bumpy saltlake terrain, so they could not let it run
faster with shaking it apart...

Would have liked to see it go 100 mph !
;)

Funny,
I just shared these vids with a friend that sells to all the big sailboat racers around the world and their zillion dollar boats,
His comment was "yes I know its a perpetual motion machine"

Never thought I'd hear those words from a fellow like him!

This is amazing!!

How do we do this with electricity or gravity ?
Push past the speed limit?

Something as simple as a sail that makes its own wind[apparent wind] and will do work indefinitely!

Good stuff!!

Larger wheels are usually worth it, even if they add air drag. I could write books on the important of sufficient wheel size for a job. Some would wish I had, to I'd preach it less online and hope people would get the book.


Here's a brain teaser. As if this stuff isn't complicated enough as it is.

In the video's, we see a vehicle which has the 100% traction wheels 1:1 connected to the propellor, in whichever gear ratio and blade pitch.
Now, HOW VITAL is this (1:1 or otherwise) hard link to make such speeds possible?
Could selective braking on the wheels and/or the prop seperately, to keep spin ratios in a preferable zone, make the cart "think" it's outfitted with such a physical link?

So, the prop upon self-start wants to turn backwards but is withheld by the wheels, right? A one-way clutch on the prop could do that. But not get it turning the "wrong way" when the cart gets moving due to the force pressig against the uncooperative prop. Then, why not use an on the fly adjustable prop. Let the prop spin up while the cart is held in place. Adjust pitch to get maximum kinetic energy storage at high rpms. An additional flywheel could store some more, later to be used to boost the wheel.
Then adjust the prop pitch to the other side, effectively reversing thrust. Don't waste rpms, and crank it open. Clutch the flywheel to the wheels. Cart will accelerate, and hopefully cross the threshold after which the magic can occur without further gearing tricks. Prop speed and cart speed line up, and are from there on brake-adjusted. The flywheel is dropped, not needed for the run itself.

An air ship might need to start with a wire to an anchor, wrapped (indirectly) around the prop axle. Same as wheels on a cart.
Would, whel the wire runs out and off the axle, the ship be able to accelerate towards 3x wind speed? The around the world record could come into jeapardy then. Imagine hitting the jet stream and merely doubling the speed.
When it sounds too good to be true, it usually is. But could a simulation give the answer?

Thanks Chet, appreciate it.
Being 100% uneducated I think sometimes allows me to think outside the box, into the obvious.

I'm pretty sure this has been invented before I wrote it. Like by a Wright brother too lazy to first dismount and then push his biplane rearward into the garage.

Too bad flywheels tend to be overly heavy to bring along for the few times they actually come to good use. Just my bold observation though. A flywheel can however be stuffed with KE indefinately, as long as the bearing is sound, the shape round, and the gearing up for it. If you let the car sit on the parking lot during the 9 days of your working day, being fed by the roofmounted prop, how much KE might it have stored? Might made for a sweet burnout down the office parking lot as you head back home.

The pitch flip would meet some good resistance (open a car door on the highway), being at top spinning speed, but then also might give a good initial kick to get up to a start, and the prop in sync.

I hope I can sleep before I have a Zeppelin freewheel its prop when having its tail pointed in the wind. Could it possibly be, that the negines internal resitance and mismatching rpms have kept a century of air ships miss out on a quick no-fuel orbit of the earth? Nah...

Hi OU blokes,

I have already seen videos of a similar(?) toy device that went "Downwind Faster than the Wind"

It is on:
http://peswiki.com/index.php/Directory:Directly_Downwind_Faster_than_the_Wind

Perhaps, this guy has *just* enlarged this kinda device?

Very Best
Same team I believe, before they upscaled.

Will we soon see a "wind" class at the RC car races? Very small startup battery allowed for some controls, the rest will have to come from the wind.

I'm just wondering whether achieving OU were not a question of education but mainly a question of daring. Just like Fire Walking.
http://en.wikipedia.org/wiki/Firewalking

At the first glance it sounds impossible witout being burnt.
Actually, anybody can safely do it.

This confirmation makes me wonder so many things.

- Rotor size. Does it need to big, or could a smaller prop be imagined that does just as well?

- Vehicle shape. Frontal surface of non-propellor part needs to be minimized, obviously as the vehicle at 3x wind speed still faces 2/3 of its ground speed in headwind.
Would an optimized vehicle be a prop, and nothing else? Or a prop front, then a tapering body behind it, and a smaller prop at the back (air compression, faster air exhaust)?
Although tail wind powers the vehicle, what is it pushing against, physically, if the cart always generates its own headwind? Is the surface of the air displaced aft of the prop important to be large, or is the main point to grab as much air as possible on the front side?

I can't wait to learn about the potential of a relatively small, say 1m across prop being stuck to the roof of a car. A small rotor line coming from the rear axle for instance.
Or better, two 50cm fans alongside a generic bicycle, driven by the rear hub or even the tire.
Could auxiliary props make significant speed and efficiency improvements?

It's probabaly been done already, but I sketched a simple airship. A string tied to a solid structure on the ground on one end, and wrapped around a pulley on the ship, spins a prop. The wire auto-centers the air ship down wind. Lacking wheels , the thing might be pretty darn fast.
I bet a prototype from a party balloon with helium and ultralight fishing line and pulley could be made to work. The balloon is self-supporting and ultra-slick through the air. Would, once the equilibrium speed is reached and the wire is released, the ship continue to speed along, or soon lose its feedback loop? Anything that could prevent this? Else we might see airships of the future throwing out an ancor at 100+mph speeds, and go even faster as a result :-)

  The wind is always moving 14mph relative to the ground.  This provides the power in the system.  Doesnt matter what portion of the wind he is in.  It is a great demonstration that what appears as static is doing work staying static.  Like a motor in a car.  The mounts and frame are doing work resisting the counter torque produced by the engine.  When an aircraft touches down the wheels are motorized to high rpm otherwise the Earth does some work on them heating the rubber up pretty good.  To save on tread the wheels are motorized to reduce this work.  Put some piezo crystals between your motor mounts and the frame.  Theyll generate.  Line a muffler with them.  Theyll generate.  Line a cylinder wall with them and lean out the mixture so you get detonation.  Theyll generate.

Yes the ground is very important here.
This will not work unless connected to the ground,ice or water some how.[yet]
The first time I experienced this [going faster than the wind]
I was 14 years old in the waters of Long Island sound on a catamaran,

There is nothing like it ,and now I see why.
It is very hard for me to get my head around this, When men that race sail boats told me  "its what we call apparent wind ,the sail makes its own wind".

Since they weren't giggling when they said this,I just shrugged and said "OH".
I didn't understand, Knowing in my head that if that where true.

Then something like what we see here is possible.

I'm still having a hard time ,even though I have done this "many" times in the last 40 yrs.
It blows in our faces every day.
The freakin wind!!
WOW

Hi Chet,
what do you mean by going faster than the the wind on
just a catamaran ?

Do you mean having the wind behind you or is the wind then
blowing from the side ?

Probably only possible with a catamaran, when the wind
blows from the side, but not from the back as it is here.
So this catamaran thing does not count.
It is a totally different thing.

With this vehicle we don´t need wind at all.

If it is accelerated by the car to 14 mph WITHOUT wind,
it just takes off and generates its own thrust.
This will never wiork just with a catamaran !

Regards, Stefan.

The prop is a sail
A catamaran [close to two times wind speed]
An Ice boat [5 times wind speed [200 mph]]
Yes the sail "must" be set on the boats at the "same"
angle of attack that the propeller has when it does its job in these vids.

30 to 45 degrees
this propeller does not know it is going "down wind"
It knows it see's the wind the same no matter where it is coming from.

This is "Exactly" what is going on [in regards to the prop]

Chet
PS I may not be describing this accurately enough
you can not ask a sailor about this ,only if  he sails hydrofoil[hobie tryfoiler]
catamaran or Ice boats.

The idea of the spinning propeller geared to the wheels on the tread mill gave me an idea. Why not stick the propellers on the end of a fixed bar which is free to spin on a central shaft. The moving ground could be a motorized lazy susan or turntable.

I had a hard time trying to find pieces in the software to conceptualize the idea, so I made a very rough design. I used Lego Digital Designer which is freeware and good enough to get the basic idea out.

The center shaft would be mounted on a spike or needle like a weather vane is and be freely turn-able. The gearing would be geared up, since I couldn't find the right gear pieces I used the same as reference in the drawing. Also the propeller blades would be much larger.

Well... So if we put this "wind vehicle" on a round track, or on a square track, or any kind of closed loop track, this will become a perpetual motion machine, even if the natural wind stops completely?

Cool...

Next step: use the vehicle motion to generate electricity somehow.
