Представьте себе, да !
В научных статьях, которые я нашёл.
Не знаю, как сюда скрины скинуть, поэтому пока просто текст скопипастю.

IV. CONCLUSION
It is theoretically possible to build a wind driven vehicle that can go in the downwind direction faster than the free stream wind speed (using a propeller in the air). [B]There does not exist a definite upper limit for vehicles[/B] of this kind. As long as efficiencies are improved, [B]the velocities would also increase unasymptotically[/B]
