The invention relates to renewable clean energy field, discloses a fitness exercise energy acquiring method and system, the method includes steps: (1) user signs up and sign in the system; (2) the system acquires fitness exercise energy and its users related information; (3) the system alters acquired energy into usable energy form; (4) the acquired energy is used; (5) user benefit from the system settlement; the system comprises components: (1) fitness exercise energy information acquiring subsystem; (2) fitness exercise energy information server and communication network system; (3) fitness exercise energy acquiring device; (4) fitness exercise energy usable electrical current alteration subsystem; (5) fitness exercise energy output control subsystem. The present invention realize change of energy released during daily fitness exercise into usable energy, both do fitness exercise and generate clean energy, fitness exercises of human and animals will generate more than one hundred millions kWh per day, with reference to present fitness equipment, obtain energy conservation and environmental protection timeliness of fitness exercises.

An information processing system includes a server including a first processor provided with hardware, and a power generation device including a second processor provided with hardware. The second processor executes power generation control that converts, into electric power, kinetic energy generated as a user operates an operation unit of the power generation device, and outputs, to the server, power generation information indicating a power generation amount generated by power generation under the power generation control. The first processor identifies the power generation information and user information indicating the user who operates the operation unit for the power generation of the power generation information, and assigns worth information indicating a worth corresponding to the power generation amount with respect to the identified user information.

An electric generator which can be coupled to an exercise machine is described. The electric generator is connected to a power grid. Using the mechanical movements of the exercise machine, the generator can produce and feed electricity into the grid, thereby creating a decentralized grid system which is immune to node failures. The generator can communicate with a smart device of a user. The generator can inform the user of the amount of electricity generated by the user while working out. The generator or an application of the smart device can communicate this data to a service provider. Using this data, the service provider can pay the user for the electricity generated. In particular, the service provider can utilize a cryptocurrency to reward the user for the human generated electricity.

A motor-less leg-powered curved treadmill produced that allows people to walk, jog, run, and sprint without making any adjustments to the treadmill other than shifting the user's center of gravity forward and backwards. A closed loop treadmill belt running between front and rear pulley rollers is formed with a low friction running surface of transverse aluminum, wooden, plastic, rubber or carbon fiber slats attached to each other in a resilient fashion. An essential feature of treadmill is the concave shape of the upper portion of the belt running surface, the treadmill configurations ensure that this shape is maintained during actual use. These configurations prevent the concave upper running surface portion from being pulled taut into a flat shape between the front and rear pulley rollers. The slats of the treadmill each have an end view crossectional I-beam shape, for strength and stability of the slat positioned upon the treadmill belt.
