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.

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.

A sporting apparatus comprises a structure body, an endless belt, an electricity generating unit, a position sensing unit and a modulation unit for continuously outputting electricity as the sporting apparatus is continuously operated. The electricity generating unit transforms kinetic energy, which is transmitted from the endless belt, into electric power. The position sensing unit senses a position of a user on the endless belt so as to generate a sensing signal. The modulation unit includes a DC/AC inverter, a current sensing element, an inductor and a semiconductor switch with a controller. The current sensing element senses an armature current outputted from the electricity generating unit and outputs a signal to the controller. The controller controls the duty ratio of the semiconductor switch to control the armature current, so that the armature current is adjusted according to the sensing signal for controlling the rotation speed of the endless belt.

A manually operated treadmill a deck and a tread belt encircling the deck to provide a movable, continuous running surface during operation of the treadmill. Further, the treadmill includes a transmission connecting a flywheel to the tread belt and a resistance unit disposed to adjustably apply a resistance force to the inertial motion of the flywheel.

The present invention provides a farm animal-operated conveyor and generator apparatus and a method for powering thereof, wherein the apparatus comprises a generator, a generator drive belt, a drive roller, a conveyor belt, a drive drum, a central bearing post, a drive gear, electromagnetic yokes, an intermediate gear, a pinion gear, a beveled gear, conveyor chassis, and a secondary intermediate gear. The electromagnetic yoke automatically collars a farm animal, which in turn rotates the drive gear and drives the conveyer belt and the generator. The movement of the farm animal powers the conveyer belt for transporting farm products, and drives the generator to generate electricity.
