Maybe adding an electric motor would be a bit difficult, but some form of wind-driven arrangement might be possible. The change in angular momentum of a heavy wheel, going from 0 to 120 knots in less than one second is quite considerable, I will leave the mathematics to those with a slide-rule to calculate.

Yes, the rubber burnt and the shock load on the gear and airframe must be considerable, but I have a theory that the Dunlops and Goodyears of the world keep buying up patents.
