Introduction

First the overview of the system. In words, we are harvesting the energy from stationary bikes. The energy is converted to regular AC power. We also monitor the energy flow wit the Open Energy Monitoring system. The bike stands we designed fit regular bikes. The bike wheel drives an electric motor with converts the mechanical energy into electric energy. The DC power is conducted through a diode and through a current sensor. Then the different cables are connected to the supercapacitor. This is the common point. From the supercapacitor we draw the power for the solar inverter that converts the fluctuating DC power to regular AC power. We monitor the power before the common point. An Arduino takes in the values of the current and voltage and transfers it to a Raspberry Pi that logs the data. An app on the smartphone allows to visualize the data.
