Grids for railways
Main article: Absorption ability network
In some countries area electric trainsdisambiguation bare run on low abundance AC (e.g., 16.7 Hz and 25 Hz) power, there are abstracted individual appearance absorption ability networks operated by the railways. These grids are fed by abstracted generators in some absorption powerstations or by absorption accepted advocate plants from the accessible three appearance AC network.
edit Superconducting cables
High-temperature superconductors affiance to accommodate ability administration by accouterment lossless manual of electrical power. The development of superconductors with alteration temperatures college than the baking point of aqueous nitrogen has fabricated the abstraction of superconducting ability curve commercially feasible, at atomic for high-load applications.24 It has been estimated that the decay would be bisected application this method, back the all-important algidity accessories would absorb about bisected the ability adored by the abolishment of the majority of arresting losses. Some companies such as Consolidated Edison and American Superconductor accept already amorphous bartering assembly of such systems.25 In one academic approaching arrangement alleged a SuperGrid, the amount of cooling would be alone by coupling the manual band with a aqueous hydrogen pipeline.
Superconducting cables are decidedly ill-fitted to top amount body areas such as the business commune of ample cities, area acquirement of an alleviation for cables would be actual costly.26
edit Individual wire apple return
Main article: Single-wire apple return
Single-wire apple acknowledgment (SWER) or individual wire arena acknowledgment is a single-wire manual band for bartering single-phase electrical ability for an electrical filigree to limited areas at low cost. It is principally acclimated for rural electrification, but aswell finds use for beyond abandoned endless such as baptize pumps, and ablaze rail. Individual wire apple acknowledgment is aswell acclimated for HVDC over abysmal ability cables.
edit Wireless ability transmission
Main article: Wireless activity transfer
Both Nikola Tesla and Hidetsugu Yagi attempted to devise systems for ample calibration wireless ability transmission, with no bartering success.
In November 2009, LaserMotive won the NASA 2009 Ability Bright Challenge by powering a cable climber 1 km angular application a ground-based laser transmitter. The arrangement produced up to 1 kW of ability at the receiver end. In August 2010, NASA apprenticed with clandestine companies to accompany the architecture of laser ability bright systems to ability low apple apogee satellites and to barrage rockets application laser ability beams.
Wireless ability manual has been advised for manual of ability from solar ability satellites to the earth. A top ability arrangement of bake or laser transmitters would axle ability to a rectenna. Major engineering and bread-and-butter challenges face any solar ability digital project.
