Think of it like an electric generator. The big ones that are used in
power stations don't use permanent magnets; both the rotor and stator have
coils.
In order to extract power from the stator windings, the coils in the rotor
must be powered. Once the generator is producing power, you can obtain the
power for the rotor coils from output of the generator itself.
The generator produces far more power than is necessary to power the rotor
coils. This isn't a "free lunch", as the generator is taking energy from
the turbine. But it has to use some of the energy it produces to power the
mechanism by which it extracts that energy.

1. Now extract more power from falling water to make the turbine turn
faster than the water pushing it.
2. Use some of that extra turbine speed to pump some discharge water
back up to a higher level, bringing turbine speed back to normal.
3. Release the water that you raised, to power more turbines.
4. goto 1.

Define "normal". In any case, there's no problem pumping "some discharge
water up to a higher level". You certainly won't be able to pump *all* of
the water back up to its *original* level.

3. Release the water that you raised, to power more turbines.
What's the point? The energy obtained from the additional turbines would
be less than that taken from the first turbine to pump the water.
But that has nothing to do with the propeller-cart.

Right. People keep confusing the BeanieMobile with perpetual motion.

And the truck will go up slower than the jack handle goes down. She

In that the air is free and the wind is made of the air
yes there is.
it doesn't take much force to maintain the speed.

But it _is_ powered. By the tailwind.
Think of it like this:
1. First of all, the wheels are geared to the prop so that when the
cart moves forward the prop will turn counter-clockwise (from the
video) when looking into it from the front of the cart.
2. If there's a headwind the prop will be acting like a windmill
(turbine) and will turn the wheels so that the cart heads into the
wind.
3. If there's a tailwind, the drag from the prop (and whatever else
there is for the wind to push against at the rear of the cart) will
cause the wind to push the cart downwind, which will make the wheels
turn in the direction to cause the prop to rotate CCW, just as if
there was a headwind.
Now, since there's no headwind and only a little resistance in the
drive train (including the losses at the wheel/road interface, the
tailwind will cause the cart to accelerate, and the prop to spin
faster and faster as the cart hurtles down the track.
Eventually, when the cart reaches wind speed and is no longer being
pushed by the wind, the thrust from the prop will drive it into the
wind and, eventually, the prop will turn into a turbine and from 2,
above, will extract power from the headwind and feed it to the wheels,
which will keep the cart heading into the wind at the speed where the
power extracted from the headwind will equal the cart's losses.
That's my take on it, anyway...

Nope, the drag the cart presents to the wind is causing the wind to
push it forward, and the torque developed by the wheels as the wind
is pushing the cart forward is transferred to the prop through an
arrangement which causes it to turn bacward with respect to the
prevailing wind.

No, _that's_ wrong.
You're forgetting that the prop is being turned backwards
intentionally, by having the cart's drag catch the wind from behind.
Since the wind is coming from the rear it pushes the cart forward, and
the torque developed by the wheels, as they turn, is transferred to
the prop by gearing it so that the prop will turn backwards with
respect to tyhe prevailing wind.

But that's not how the cart's wired. See 1, above.
It's a contradiction.
Imagine the car is symmetrical, no front or back, just a box on wheels
and a prop on the roof.
In 1 and 2, it's wired to push the car upwind. In 3, it's wired to push
downwind.

No.
In 1 and 2, the tailwind is pushing the cart, which turns the wheels,
which makes the propeller spin backwards.
In 3, the prop is acting like a turbine and the headwind spins the
prop, which turns the wheels, which drives the cart into the wind.
It's interesting to note that whether the wind is coming from the rear
or the front, the rotation of the prop is always in the same
direction.
I've got a sketch I'm working which (hopefully) will make things
clearer, and I'll post it to abse when I finish it, tomorrow sometime.

I hope you're using gears, shafts, chains and sprockets, visible stuff.

I've been working on mine! :^)
Nothing I have the nerve to present yet, but it's real simple - the
wheel is a pulley, there's another pulley on the propeller shaft, and
there's a twisted belt between the two. That's all it takes.
It looks like as the car goes faster, the wheel goes faster too. And
then the propeller goes faster, so the car just keeps going even faster.
This is scary.

Perfect!
I used a sprocket on the prop shaft and another one on a right-angle
drive with the input to the drive being the wheel axles, so I wouldn't
have to twist the chain, but I like yours better. Much simpler.

But thrilling, yes?
How about that moment of discovery when you saw the thing working, in
your mind, for the first time?
