SAVortex, a company founded by Syed Ahmed, a participant in BBC’s The Apprentice, claims to have launched the greenest hand-dryer - The Vortex. It features unique patent-protected spinning air technology, using no heating elements and recovering energy as it works.

The Vortex can dry hands in 10-15 seconds and its low heat emissions can help reduce electricity bills. It has the lowest carbon footprint dryer in its class, said the firm.

The hi-tech aluminium casing is coated with an anti-bacterial layer for hygiene.
