WALT Posted April 12, 2008 Report Share Posted April 12, 2008 For 40 years I have designed telecom power systems for optimal protection of telecom service continuity. I have also taught for several major telecoms in this regard. Just wondering if anyone out there would like to discuss this subject? Link to comment Share on other sites More sharing options...
mariomaggi Posted April 14, 2008 Report Share Posted April 14, 2008 WALT, few years ago, when I heard the word "flywheel" as energy storage system for power quality, I considered this technology "old" without looking inside. Now I've changed my idea, flyweels are installed also here in Italy for telecomm power protection. Here levitating high-speed flyweels under vacuum are called simply "supervolani", in one word. They are particularly interesting to supply high power for few seconds.

WALT Posted April 14, 2008 Author Report Share Posted April 14, 2008 Hello Mario: Thank you for your comment. I have heard of flywheel energy storage being used in Europe for short time power back up. I find this energy back up approach very interesting and do not doubt that it can have application. I read that a concern is the potential disintegration of the flywheel and that this necessitated that protection from that be provided. One method was to bury the flywheel underground in a vault. Is this still the current method for protection from disintegration? Kind regards, Walt Link to comment Share on other sites More sharing options...
mariomaggi Posted April 14, 2008 Report Share Posted April 14, 2008 Dear WALT, in these weeks I'm very busy and I cannot reaply in the proper way. Disintegration of a 1-piece steel flywheel - well designed - never happened! Speed at the circumference is alittle bit beow sound speed. Many flywheels are running in data center, offices, hospitals, without any safety problem, also during low-level earthquakes, since meany years ago, for 365 days/365 Regards Mario Mario Maggi - Italy - http://www.evlist.it - https://www.axu.it Link to comment Share on other sites More sharing options...
