Directorly Downwind Faster than the Wind

[BEP]

Do you guys actually think that the wind is not needed to go fast down level ground? Free energy everywhere, you just need to want to tap it? Right?

No. For this or anything to work there must be a difference of potential, a source of usable energy. In this case it is the wind. I think this cart is analogous to a step-up transformer. There is no energy gain. There is only gain in velocity. The prop needs to push against something moving faster than the ground.

If there is any free energy to be had, it's going to have tpo be in conjuction with gravity.

Last time I was on the salt flats it was pretty flat. Gravity could be made part of this but what goes down looses going up, unless there is enough wind.

I have to say ,your gravity "angle" in all this seems "plausible"

I am quite sure that big brain of yours will figure a way to use this

"effect" towards a better understanding of what can be done here.

Listening to you fellas bang this around, is helping to understand whats going on here!

Thanks

Besides it might help make my sail boat go faster 
As Bep [or any sailor] knows ,this is always important!

Aye! Me Bucko! Not much more fun than jumping a barge wake while under tack with a sloop and 3/4 of your keel showing! 2X wind speed could mean that jump could have been at 50 knots. With a huge prop spinning instead of taught mainsail and jib, it could be an ugly result.

I wasn't saying THIS CART is getting its gain from going downhill, I'm not a debunker, I'm a believer.

@ramset
My brain may be volumous, but most empty, untrained and uncoordinated.
Should it be possible, in a simple setup just like DDW, maybe slightly adjusted gearing and prop style, to beat gravity, this would be just like creating your own wind. Or, OU. Setup could be mounted on a wheel of furtune kind of setup, and just mill away. For this to happen, the energy taken from the wheels of the "cart", should somehow bring a gain when converted to prop trust. this has  "too good to be true" all over it, but I like it as a brain teaser.

Although gravity doesn't give a back draft when you surpass it, it also doesn't offer anything to press off against, like tailwind does.

It seems, as long as high-tech, efficient system are used, any vehicle used in the outdoors, could benefit from a wind prop to be engaged with its water prop or wheels when appropriate, be it roughtly downwind or upwind. More surface, more power, so mount as many on the sailboat as fit!

What about a tailwind powered hovercraft. Could it be done?

Even better than a catamaran would be an aquafoil type craft. Almost only the prop in the water, to turn the wind prop on top. An ground effect hull might offer nicer lift even than an hydrofoil, lift for Watts of resistance?
