I have never heard of this inertia disk system on Swiss bus trolleys! Can you tell us more about it?
Probably that:

As everyone knows, it was a huge success, and we keep seeing "gyrobus".
And for those who want to understand, there is nothing magical about it. Just a search to get rid of the jumble of overhead power lines. The energy used, except for the flywheel losses, is the same. Simply instead of continuously supplying overhead lines, we "pump" a lot in a short time to start the flywheel, which then restores this energy as the bus needs.
Energy recovery is also not in doubt, at least not by me. There are TERs with recovery of the type:

Apart from the fact that these are expensive devices, which can find their place in certain uses, I do not see what this proves, compared to a "revolutionary speed bump" where it is just the initial energy that is lacking. ?
