Energy Harvesting for Autonomous Systems Neil White, Stephen Beeby
Publisher: Artech House

An increasing number of consumer and industrial products that are untethered from the electrical outlet will be powered by some form of energy harvesting (EH) technology in the near future. Several cooperative projects related to topics such as System Architecture for Power Aware Wireless Sensor Network Nodes, Energy Harvesting for technical Devices, SoC for Advanced Multimedia Broadband Access. Fully autonomous wireless temperature sensor powered by a vibrational energy harvester. The multifaceted features of aquatic exploration have an enormous bearing and hence have established a critical need for development of autonomous under water sensor network systems. Alpha Micro has introduced an energy-harvesting evaluation kit for autonomous wireless sensors and other sub-100mW applications. There are some real world applications of such energy harvesting but they are all limited to powering up things like autonomous single-chip systems (RFID's, sensor networks etc). Your calculations are actually fairly accurate. In the simplest case an untethered autonomous flying energy-harvesting unit as well as a receiver ground-station are integral parts of the complete system. Electromagnetic, and thermoelectric transduction methods for converting ambient energy, and includes an assessment of key implementation strategies for the most common energy harvesting technologies operating in portable, pervasive, and autonomous systems. Underwater monitoring systems are Existing BMFC systems have numerous issues of low power output, electrode fouling, and most significantly the lack of an effective mechanism for active power management and energy harvest.
