Should somebody make an gyroscope vehicle besides everyday vehicles?

Answer 1

Using a gyroscope in a vehicle has been among the favorite topics of Science Fiction writers for a long time, primarily because writers aren't necessarily competent engineers.

What would be the advantage of a gyroscope? There would be the possibility of recapturing some of the kinetic energy as the vehicle slows, especially if you could find a way to put that energy into the spinning gyroscope.

However, the extra mass of any gyroscope that would be able to store that much kinetic energy, would also make the vehicle far too heavy for practical operation.

If something like that were practical, automotive engineers would have jumped on it; but if you believe that there is a practical use of gyroscopes in automobiles, perhaps you could develop such a vehicle and make yourself rich.
