Abstract: A method for collecting virtual collectables comprises providing a system that facilitates the exchange and storage of virtual collectables, in which at least some of the virtual collectables correspond to physical objects. Next, one or more virtual collectables are presented to a user on a user interface of an application associated with the system. A selection for a virtual collectable from the one or more virtual collectables is then received from the user, and the virtual collectable selected by the user is exchanged for an item of value to the user. The virtual collectable is then stored in a virtual storage area of the system that is dedicated to the user.

Abstract: Air compressing tires on a vehicle can utilize tire deformation during vehicle motion to compress a gas. The compressed gas can be discharged from the tire to a pressure regulating vessel on the vehicle. The compressed gas can be stored or used for power generation on board the vehicle. In some cases, the power generated can be used to extend battery power and/or range of an electric vehicle.
