A transmission for an energy storage and recovery system comprises a variable slip transmission and a clutch arranged to transmit drive while slipping. The level of torque transmitted through the slipping clutch is dependent on the clutch force but is independent of the clutch slip speed. Preferably the clutch is provided by a plurality of clutches connected in parallel in a range extender. When drive is transferred between clutches in parallel, the clutch forces of both clutches are controlled to maintain the total torque transmitted by the clutches. This reduces torque fluctuations at the energy source/sink during clutch transfer. Where there are two slipping clutches in series, one clutch is controlled to provide the required torque and the other clutch is controlled in response to a clutch slip speed. This helps to control the speed of rotation of the mass between the clutches.

An energy storage apparatus including a spherical rotating member having permanent magnets and uniquely-identifiable location-defining elements, a plurality of coils, a controller operably coupled to the plurality of coils, a power source, and a location sensing apparatus operable to detect the plurality of location-defining elements. The controller may compare time-sequential information from the location sensing apparatus to determine a rotational axis and a rotational speed of the rotating member, operate the coils to change the rotational axis speed of the rotating member, increase energy stored by the rotating member by increasing the rotational speed by operating the coils to generate magnetic fields that interact with the permanent magnets, and withdraw energy by operating the coils to generate magnetic fields that interact with the magnetic fields of the permanent magnets to produce induced current in the coils and directing the induced current to a power delivery location.

The Kinetic Kar will have a large high pressure chamber filled with hydraulic fluid pressured up to 20 ton for the initial motion of the car. The pressure harvested by means of pumps, pistons, valves, and electrical gadget will be too high for the high pressure chamber. It is estimated that the car will move from zero to 20 miles in a matter of 2 seconds and run at up to 150 miles per hour for a mile before pressure tank is depleted totally. It will only take 3-4 seconds for pressure reservoir to replenish.
