Low-cost flywheel demonstration program. Final report

The Applied Physics Laboratory/Department of Energy Low Cost Flywheel Demonstration Program was initiated on 1 October 1977 and was successfully concluded on 31 December 19'9. The total cost of this program was $355,190. All primary objectives were successfully achieved as follows: demonstration of a full-size, 1)kWh flywheel having an estimated cost in large-volume production of approximately $50/kWh; developmeNt of a ball-bearing system having losses comparable to the losses in a totally magnetic suspension system; successful and repeated demonstration of the low-cost flywheel in a complete flywheel energy-storage system based on the use of ordinary house voltage and frequency; and application of the experience gained in the hardware program to project the system design into a complete, full-scale, 30-kWh home-type flywheel energy-storage system.
