Also you say you need 10 MIN of ride through. Powerware's flywheel
system has 120 SEC (2MIN) of ride through and an MG set isn't going to
give you 5 times the ride through if you have 1/5th the load like a UPS.

You probably also realize that the maintenance (lubrication, bearings,
etc) on a flywheel easily exceed the amount of maintenance on a sealed
battery system.
The difference (mainly) is that you have relatively uniform maintenance
costs instead of the jagged-saw tooth (with battery replacement) that
UPS systems have.

I'm starting to design a new 1000sqf datacenter in a building that has
reliable generator backup. So I will only need about 10-15 mins of UPS
power (if the generator won't start in that time, it won't start for a
long time :-). I will only need AC power.
I was wondering what peoples opinion was of the flywheel type UPS?
The plus I see is that there is no battery bank to worry about.
