Carrot Tech.

Via The Scotsman:

FROM dangling to angling. The humble carrot is set to be used in
ways never imagined before, thanks to a discovery by two Scottish
scientists who have found a way to convert the vegetable into an
advanced material to make products from fishing rods to warships.

The development is the brain-child of Dr David Hepworth and Dr Eric
Whale, who have created the material, named Curran, at their company
CelluComp in Burntisland, Fife. Their first product – a rod for fly
fishing – goes on sale next month. . . .

At the moment, the company can make materials which are around 80 per cent carrot, with carbon fibre making up the remainder.

The new "Just Cast" rods are around 50 per cent carrot – each made with around 2kg of the vegetables.

But it is hoped that as the technique is developed, they will
eventually be able to make products which are made from 100 per cent
biological matter – carrots and other plants.

Dr Hepworth said they were already looking at using other vegetables such as turnips, swede* and parsnips.

*A swede is a rutabaga.
