For Christ's sake, land sails already go 2-3 times faster than the wind using the exact same principles used in these carts.
No, they don't exactly the same principles.
Land sail, and sailboats too, cannot sail faster than the wind when they are aimed directly downwind.
But somehow, this cart can. And that's what makes it difficult to understand.
