A TEAM of designers has developed a Brussels sprouts battery.

Determined to find an alternative use for the much-maligned vegetable, the Big Bang team spent four weeks coming up with the invention.

The final product is made up of five power cells each holding 200 sprouts.

Chief designer Sean Miles said: “Each of the 1000 sprouts has a copper and zinc electrode embedded in it.

“What we are doing is allowing a chemical reaction to take place between the two, which creates the energy we turn into a current.”

The battery generates 62 volts of electricity, which is now being used to light LED lights on a Christmas tree.
