Dear All, forgive me for inflicting yet again my views on the relationship between our rotten political system, the voting system and energy and other (health, environment, media, financial, tax, justice) vital policy issues. In a nutshell, it seems blindingly obvious, ( to me anyway) that with our system, where the PM wields enormous power, […]Read More
James Birkin writes as below: there is now a wiki at (http://claverton.wikispaces.com/+HVDC+-+List+of+interested+persons+and+organisations at which you can add target organistations) Dear Attendee, I am compiling a list of all organisations or individuals supporting the concept of a Supergrid.Read More
Dr. Czisch gave a very interesting presentation the contents of which is summarised here, Rather than publish a paper on this set, Gregor has given us these links to his site where the varous papers can be studied.
The most relevant one for English speakers is probably this one:

Summary – this article offers compelling reasons for using a flywheel in combination with a diesel generator for UPS. Essentially batteries are the weakest point of any generator, and the flywheel eliminates the need for them, by storing enough energy to start the generator, and to provide no break power whilst the generator is starting. This article is written by and features Active Power who manufacture these systems.
As compared to other energy storage technologies (i.e., flow battery, compressed air, hydrogen, lithium ion battery, etc.), flywheel technology is a very mature, field proven technology. It’s worth noting Active Power was the first to commercialize a mechanical flywheel energy storage system and soon after patented the integration of UPS electronics with flywheel energy storage. Flywheel operation is very well understood and Active Power alone has more than 2,100 flywheels deployed in the field to date with more than 55 million hours of runtime. Flywheels present the most power dense energy storage technology when used as a bridging device between an outage and on to a generator.Read More
