I'm going to need to see your work for the 50mph to 50kw conversion.

1 Kw per mph sounds pretty bad. I would've thought electric cars are more efficient than that.

Also one is a force while the other is a speed. You'd need a lot of assumptions to go from one number to another single number.

Googling a rough average returned 0.346 kwh/mile for electric cars between 2000 and 2022 (wide range, im aware). Traveling at 50MPH, you go 50 miles in 1 hour (assume you're already going 50, and stay at that speed). So you'd use [0.346KWh/mile] *[50 miles/hour] = [17.3 KW] per hour @ 50 MPH

One of the problems is that air resistance increases at a squared rate vs velocity, so that average is only really accurate at one specific speed (which tbf might actually be 50mph). But this is a lot more accurate than just replacing "mph" with "kw" lol.

My biggest red flag was the picture of a commercial-grade-looking generator when plug in hybrids can fit the generator plus electric motor, battery, AC, and all the other stuff needed under the hood.
