1. Aeroller Flywheel Braking System Low-cost Kinetic Energy Recovery System (KERS) for use in Amateur and Semi-Pro Le Mans-style racing.

2. Where does the momentum of the car go during braking? Waste heat The energy normally lost to heat during braking be easily stored in a flywheel (by means of a CVT) and used as a boost during acceleration.

3. Many F1 race teams used super-high-RPM flywheel systems in the 2009 race season. Mechanisms were so expensive that in 2010, all participating teams agreed to not use KERS. Background An example of a high-cost Flywheel designed to run at >70K RPM

4. What is the simplest way to convert angular momentum into compressed gas and back again? How can more kinetic energy be stored in a slower-rotating, less expensive flywheel?

5. When relaxed, the wheel has a relatively low rotational inertia. As the wheel accelerates it forces the weighted pistons away from the axis, storing energy in the form of compressed gas.

6. Shift in weight away from the axis increases rotational inertia which permits the wheel to continue storing momentum even at high RPM

7. In the same way that an ice skater increases their velocity by pulling their arms inward, the inward pressure against the pistons creates an accerlerating force which, in equilibrium with the centripetal force forcing them outwards, slows deceleration despite energy output. An Aeroller flwheel can store many times the energy of a traditional flywheel of the same weight and velocity

8. Gyroscopic forces can be harnessed to improve performance In racing, most braking occurs right before a curve
