Efficiency of harvesting energy from colored noise by linear oscillators.
We investigate the performance of a linear electromechanical oscillator as an energy harvester of finite-bandwidth random vibrations. We derive exact analytical expressions for the net electrical power and the efficiency of the conversion of the power supplied by the noise into electrical power for arbitrary colored noise. We apply our results to the important case of exponentially correlated n...
متن کاملHarvesting Energy from Galloping Oscillations
The aim of this work is to exploit flow-induced vibration for energy harvesting. A cantilever beam carrying a tip mass in the form of a lightweight box having a square, triangular, or semicircular cross-section is designed to undergo galloping oscillations when subjected to an incoming wind stream. Electrical power is extracted from the self-excited flexural vibration of the beam through an ele...
متن کاملEnergy Harvesting from Train Vibrations
An investigation is carried out into how much energy can be harvested from the vibration of a passing train using a mechanical oscillator. The harvested energy could be used, for example, to charge sensors mounted on the railway track for structural health monitoring. The dominant frequencies due to a passing train are determined for a specific train and speed from a recorded acceleration time-...
متن کاملHarvesting Energy from CO2 Emissions
When two fluids with different compositions are mixed, mixing energy is released. This holds true for both liquids and gases, though in the case of gases, no technology is yet available to harvest this energy source. Mixing the CO2 in combustion gases with air represents a source of energy with a total annual worldwide capacity of 1570 TWh. To harvest the mixing energy from CO2-containing gas e...
متن کاملEnergy Harvesting from Rotating Structures
In this paper, we analyze and demonstrate a novel rotational energy harvesting generator using gravitational torque. The electro-mechanical behavior of the generator is presented, alongside experimental results from an implementation based on a conventional DC motor. The off-axis performance is also modeled. Designs for adaptive power processing circuitry for optimal power harvesting are presen...
