Where is the energy required to do this coming from?
From the wind. Which is travelling faster than the vehicle. Except in the immediate vicinity of the propeller.
As the vehicle approached the wind speed what would happen to the sock?
If the vehicle moved exactly at the speed of the wind, with the propeller moving, the air would appear dead still before taking into account the movement of the propeller, and so the sock would be blown strongly out behind the vehicle, making it look as if the vehicle were moving much faster than the wind.

So the parts of the vehicle that are travelling slower than the wind receive energy from the wind but not the propeller? If I took off the propeller would the vehicle go faster or slower?
The point is that the propeller blows the sock backwards, regardless of whether the vehicle is moving faster than the wind; and this is shown as proof that it’s travelling faster than the wind.

It is a very good feature of the video (from rationality test standpoint) that this piece of evidence is compromised: you are handed a conspiracy theory right away, and so when rationalization kicks in, you know what to point to.
