When it comes to electricity grids, matching supply and demand is a tricky business. Utilities need to have spare capacity on standby to provide additional power whenever it is needed and that s expensive.

What s more, the problem is set to get worse given the growing reliance in many parts of the world on wind and solar energy, which is often unpredictable and cannot be switched on to match demand.

There are essentially two ways to tackle this. The first is to invest in more infrastructure, such as additional conventional power station ....etc

ABSTRACT

This paper presents a scheme for designing a kind of wireless charging system aimed to provide power transmission for personal mobile devices such as cell phone. This scheme consists of three parts: wireless power transmission design, wireless signal transmission design and charging manage design. A circular array consisting of some antenna elements is employed in the scheme as transmit access of power and signal. In the supposed indoor condition, the transfer efficiency can up to 66%. The charging manage adopt a close-loop optimal ....etc

Abstract
Organic electronics, (plastic electronics or polymer electronics), deals with conductive polymers, plastics, or small molecules. It is called 'organic' electronics because the polymers and small molecules are carbon-based, like the molecules of living things. This is as opposed to traditional electronics (or metal electronics) which relies on inorganic conductors such as copper or silicon. Polymer electronics are laminar electronics

Wind-powered mobile phone charger
The project is developed by UK wind turbine specialists. It is seen as a solution to the problem of keeping your mobile phone fully charged when miles away from a conventional electricity source. The product is a a small, portable tent mounting mobile phone charger. It uses uses stored kinetic energy to charge the mobile phone. This is an ecologically friendly phone accessory and weighs only 150g. a conventional horizontal axis wind turbine is present alongwith a propeller diameter of 30cm. This in turn ....etc

ppt on smart charging technology for portable electronics devices

Abstract

In this article we describe our efforts of extending demand-side control concepts to the application in portable electronic devices, such as laptop computers, mobile phones and tablet computers. As these devices feature built-in energy storage (in the form of batteries) and the ability to run complex control routines, they are well-suited for the implementation of smart charging concepts. We developed simple ha ....etc
