I found this while looking for something completely different (story of my life  ).
It seems reasonable, what do you think?

No I don't think it would work.  I skimmed the article and I think I see the concept however I believe he is ignoring the equal and opposite reaction by the bullet being slowed down even if it is done by friction.  I may be wrong but I don't sense it would work.  However if he was correct it would seem that is a very simple way to free energy.

I have few tips for improvement. Braking can be done magnetically. With magnetic braking heat is also released, but no material is damaged.

next tip:
Instead of ball, can be used aluminum piston and electromagnet. Piston must be very conductive but not magnetic. Piston goes back and forth between electromagnets. While piston goes in one direction electromagnet is off. When piston reach top dead, it switches on electromagnet. On second cycle when piston goes in another direction, it goes with braking effect. In starting position it switches electromagnet off. Cycle is now complete.

3-rd tip:
By using optical switchers(like in old computer mouse), entire mechanism can perform incredibly fast with high RPM

  If a hot ionized gas is magnetically accelerated,  travels a low friction path along an eliptical bend and encounters a brake at the same end as the accelerator then your braking adds to the inertia of the craft as well as the acceleration cycle.

sparks if you add up all the accelerations in your loop they add up to zero.
every change in speed and direction requires acceleration. not just the start
and finish.
