A There was an error working with the wiki: Code[1] is similar to a battery in that it is a medium for storing electrical energy. However, a capacitor is a much simpler device than a battery, it cannot produce new electrons -- it only stores them. Capacitors that are scaled up to power levels required for delivering power to vehicles and the utility grid are known as Directory:Ultracapacitors.

Latest: Directory:Solar > Directory:Solar PhotoVoltaics / Directory:Storage > Directory:Capacitors > Directory:Graphene > Directory:Sunvault Energy Inc. Graphene Generator and Supercapacitor Technology - Coming up with a clever way to make graphene that both collects solar energy and stores it, Sunvault expects that after roll-out in Q3, their storage device price point to get down to $40/kW-h by year end. Applications include phones that never have to be recharged. (PESWiki May 25, 2015)

Latest / Top 5 Exotic Free Energy Technologies: Directory:Solid State Generators > Directory:Solid State Batteries / Directory:Capacitors > Directory:Endless Electric Field Generator (EEFG) > Breakthrough Solid State Generator - We have finally been given permission to discuss this technology that we consider to be at the very top of our list of emerging clean energy technologies. Solid state, low (for now), continuous power, commercial in maybe 24 months, cheap, high power density, no radioactivity, no existing physics laws broken. (PESN and BeforeItsNews July 23, 2011)

Directory:Nanotechnology / Directory:Storage > Directory:Batteries / Directory:Capacitors > New battery technology may allow for complete recharging within minutes - New batteries being developed at the University of Illinois, Urbana-Champaign are said to offer all the advantages of capacitors and batteries, in one unit. They have the rapid charge/discharge capability of capacitors, while also having the ability to store large amounts of energy, like batteries. (News:GizMag March 21, 2011)

Directory:Nanotechnology / Directory:Storage > Directory:Capacitors > Print-on-Demand Power - Flexible carbon-nanotube supercapacitors could give more power to cell phones and other electronics. Researchers have made the first printable supercapacitor. This high-performance energy-storage device performs better than conventional supercapacitors currently on the market.

Capacitor research could increase storage by 7x - Researchers have developed a new type of capacitor which allows up to seven times the electrical storage potential as standard capacitors available today. This is good news for the electric and hybrid car industry, as capacitors are a possible alternative to batteries. (AutoblogGreen Jul. 4, 2007)

Directory:Hybrid Vehicles > TNO Hybrid Carlab - This Beetle finished 2nd in the 2005 Rallye Monte Carlo for Hybrid Vehicles using < 4 litres/100km (59 mpg US). A 150kW AC Propulsion electrical system powers the front wheels supplied by a generator set based on a VW 1.2 TDI 3-cylinder diesel engine and UQM generator. Peak power is supplied by a supercapacitor pack consisting of 3500F Nesscap cells.
