A Serious Mains Conditioner
Posted by: NaimDropper on 22 July 2006
No batteries, uses a flywheel.
SERIOUS UPS
At only 1100 lbs (500 kg) and occupying 6 ft. sq. of floor space it delivers 190kW of power and 2700kWs of energy.
They claim 20 years of service with their vacuum bearings. Ride-through power conditioning, etc.
Seems suitable for Naim... Anybody tried one?
I bet you could get it in Black or Olive...
Then there'd be no more "bad mains days".

Hi David,
Thanks for the post!
Although, Rats - years ago I thought of building a mechanical mains conditioner with a dirty great flywheel in, too. Seemed the obvious way to get very stable power to me, if a little simple and 'clunky', potentially noisy and a bit of a handful if a bearing seized!!
Seems there is never anything new under the sun.
The link didn't work (maybe one needs to be registered on the site?) so I googled for the concept and it appears Nasa have thoughts involving of a flywheel-based battery (based on the work done by Pentadyne that you brought to our attention). Their design could be described as 'non-trivial'...

Rich-
Sorry the link didn't work, below is the text from the site.
It would provide a consistent ride-through for certain, especially if it were synchronous. I suspect it is not synchronous, otherwise any slow-down during energy "withdrawal" would result in a change of mains frequency.
The whole thing was a bit tongue in cheek, such a device in the home would be way over the top.
But then again...

Flywheel power system
eliminates batteries in UPS
Energy storage and conditioning device can deliver up to 190 kW of power
With a design life of 20 years operating 24/7 without any major service interval, the VSS+DC flywheel-based energy storage system replaces batteries in UPS systems with a nontoxic system with a longer lifetime and higher reliability. Occupying less than 25% of the space of an equivalently sized battery system, the 1,300-lb device will deliver up to 190 kW of power and up to 2,700 kW/s of energy, and can integrate with UPS systems rated at 225 kVA or less.
In addition to energy storage, the self-contained device also provides 100% ride-through power conditioning and filtering with magnetic bearings and a vacuum-maintenance feature for a 20-year operating lifetime. Housed in a steel cabinet occupying less than 6 ft2 of floor space, the flywheel energy system can be paralleled with as many additional units as desired for higher power, longer run-time, or redundancy without requiring any communication links.

Hey David,
Thanks for the info - I too was being a little tongue in cheek but I guess that doesn't always come across via text.
Still, it's good to know that someone liked the idea of a flywheel enough to build one into a commercial product, and that someone else apart from me (you) thought it appropriate for hifi.
Don't think I'll be placing an order for one anytime soon though!
Cheers!
Rich.
