Modular Electromechanical Batteries for Cost-Effective Bulk Storage of Electrical Energy

Projected 95% storage efficiency. - Simple and straightforward architecture promotes low cost, high reliability and decades of lifetime. - Long energy storage lifetimes (hours) due to extremely low parasitic loses. - Long device lifetime (10 to 20 years - a consequence of 100% passive magnetic bearing design (no electromagnets, amplifiers or sensors). - Ease of scaling; a few kwh (~12" diameter) to several hundred kwh per EMB unit (~72" diameter). - Different EMB unit sizes can be combined into an integrated system to promote both short timeframe operation (minutes) and long term usage (hours).
Patent Abstract: 
A CAD image of an EMB concept is shown below. Identified are several of the key components showing their relationship to one another.
