Pacesetters
Pacesetters was a proposed energy-harvesting scheme created by Facility Architects, a London-based design firm. Its announced aim was to harness the vibrations generated by activities within a city and generate electricity for lighting purposes. The electronics company Philips and Hull University also took part in the project. ''The Independent'', 25 October 2006 History DARPA (Defense Advanced Research Projects Agency) of the United States pioneered research into the field of energy harvesting from vibrations, wanting to reduce the use of heavy rechargeable batteries that power communication devices carried by soldiers into battlefields. Most of the research was spent in development of "heel-strike" Electric generator, g ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Energy-harvesting
Energy harvesting (EH, also known as power harvesting or energy scavenging or ambient power) is the process by which energy is derived from external sources (e.g., solar power, thermal energy, wind energy, salinity gradients, and kinetic energy, also known as ambient energy), and then captured, and stored for small, wireless autonomous devices, like those used in wearable electronics and wireless sensor networks. Energy harvesters usually provide a very small amount of power for low-energy electronics. While the input fuel to some large-scale generation costs resources (oil, coal, etc.), the energy source for energy harvesters is present as ambient background. For example, temperature gradients exist from the operation of a combustion engine and in urban areas, there is a large amount of electromagnetic energy in the environment because of radio and television broadcasting. One of the earliest applications of ambient power collected from ambient electromagnetic radiation (EMR) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
