5 A Scalable Flywheel That Can Store And Discharge Grid Scale Power In A Green Economically Viable Manner

6 The unit’s kinetic wheel is 120" tall and 48" wide. Total weight of the wheel is approximately 80 thousand pounds. Total weight of the entire unit is approximately 100 thousand pounds depending on size of motor/generator set. Unit exterior containment is 11 feet wide, 11 feet tall and 30 feet long. At Max Operating Level (10,000 rpm): 30 gigawatt seconds 8.1 megawatt hours Power interface is set at 480 volt 800 amp input and output mode for basic system.

7 Economic Metrics (base unit 480v 800 amp): Manufacturing Cost: $200,000 installed cost per kwh: $26 lifespan: 25 years maintenance schedule: quarterly Efficiencies: input/output efficiency: 90% Rapid Onset Load Suppression: 80%

Our Achievements To Date Years of R&D by the inventor resulted in solving the Flywheel riddle. Commissioned a marketing study to be completed by Dr. Jerry Jackson Power Tree Corp established in 2008 and funded. Recruited a talented and seasoned team of professionals. Applied for patent through Hamilton Brook Smith & Reynolds. Gen 3 unit built and in operation. Intertek testing of Gen 3 proved efficiencies. Currently patent pending. Established a manufacturing joint venture. Moving into Coconut Creek manufacturing facility. Received Congressional and State support. Signed multiple LOI’s with potential beta site partners 8
