Yes, yes, reksio. What you've done is confuse speed with velocity. True wind is a force, it has both magnitude and direction. If the wind is blowing due south at 10 meters per second, there is no trick of physics you can do to make that wind push anything due south at faster than 10 meters per second. Period. In fact, you're never going to make that wind push anything due south at exactly 10 meters per second, because the laws of conservation of energy are going to get in the way of that. You will have energy loss in the transfer of kinetic energy of the air molecules to whatever they're pushing, you'll have drag, friction. Like I said before, there's no such thing as a free lunch.

While you can use that wind blowing due south to push something southeast at a greater speed than the prevailing southerly wind speed, the vector component of that pushed vehicle's travel due south is never, ever, going to be greater than 10 meters per second due south.

Wind is a force, just like gravity is a force. For our purposes on earth, gravity is a downward force. Are you telling us there is a way to increase that force simply by changing the direction of falling from straight down to falling at some other angle? This would, of course, instantly negate the study of ballistics. I bring this up as an example to illustrate that you cannot break up vector components of a force in such a way that their vector totals exceed the original force. Ever.
