New pan heats food 40% faster thanks to its 'fins'

• The energy efficient Flare design, which has fins, was dreamed up by a professor of engineering at Oxford University
• The shape of the pan channels heat from a gas flame across the bottom and up both sides, to capture energy that would otherwise be wasted
• This means it can heat food faster using 40 per cent less energy
• The pans, which are made from cast aluminium, will go on sale at Lakeland next month, with prices starting at £49.99
