If recent entries to design competitions are anything to go by, inventors are increasingly aware of the demand for simple, eco-friendly devices.

The Concept Products Awards will reward one winner, decided on by the public, with £2000 at the Ideal Home Show on 21 March.

The products have been conceived by students at various design colleges and universities.

Although the products aren't in production, prototypes of the designs have already been made, and include a water saver and home energy monitor.
