What part you disagree with ?

a) electric energy is the electric power integrated over time.
b) electric power is the product of electric potential and electric current.
c) electric current is a stream of charged particles, such as electrons or ions, moving through an electrical conductor or space.

The c) is copy paste from wikipedia (first line in a google search).

You missed out your definition of electrical potential. I'll assume voltage.

You say energy flows in the wire, and I know voltage can be measured with a DMM or voltmeter.

How should I attach both probes to the wire to measure it? Everywhere I try I get a number number very close to zero, indicating zero powre!

I think those 3 points are sufficient unless you want to say that one of them is incorrect or you want to say that there are electrons or ions traveling that 1m gap between wires.

Oh my God. Hahaha. What a blatant refusal to define 'voltage'.  :-DD :-DD

Do you understand that with zero current there is zero power and thus zero energy ?
Unless you disagree with one of those 3 points electrical energy doesn't travel outside the wires.

One long wire is at 20V (it's the wind), another is at 0V (ground).
Make a device which goes fast, say 10 times faster than electron drift speed.

Mech
P = F * v

Electric
P = V * I

Both cases 200W = 20 * 10

I asked to provide the circuit you will use at the output of the power supply so that any of those values can be higher than the max available.
If you use a resistor divider you can provide me with any voltage output between 0V and 20V but nothing below or above that same as you can get a direct downwind, wind powered vehicle at any speed between 0 and wind speed but not above or below unless you use energy storage.

And I will really love to see how you can get more than 100% power output after that circuit.

Nah I don't think you understand the size of the atmosphere.
So the equivalent problem is: given a capacitor with 1GF (gigafarad), charged at 20V how do you get 200W during 3 minutes, for example  200V-1A.
And of course you can use energy storage, much like Blackbird uses energy storage: moving parts (wheels, propeller, gear), moving car.
