A flywheel support system isolates, the flywheel (11) and its motor-generator (21) from the driving environment of an electrically powered motor vehicle. A suitable liquid (9), placed between the outer (8) and vacuum (10) housings of the flywheel assembly, provides buoyancy and damping to the vacuum housing, cooling the motorgenerator, and serves as one of the barriers to rotor energy and angular momentum transfer in the event of and accident or failure.

Why it's free to use
- Filed November 7, 1994. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended November 7, 2014.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
