The Freecycle Network is an example of this. The concept is as simple as it is revolutionary. A non-profit organisation with a global network provides a one-stop forum for those wishing to acquire items – from furniture to electronic gadgets – and those wishing to dispose them of, all completely free. Car-sharing services are another such innovation. A vast network of registered users can pick up a car from any of a number of parking spots, use it for as long as necessary, pay by the hour then leave it at another convenient spot. Or, on a more intimate scale, the utilisation of ‘crowd wisdom’ that networking sites such as Twitter have made possible, enabling any user to benefit from the real-time expertise of a large number of individuals. At a time when the global economy is far from robust, such resource efficient and environmentally friendly models capture the spirit of the times.
