 A firm called Niobolt, which is based in Cambridge, conducted some tests yesterday on a new super fast charging battery that it's been developing. And it managed to charge it on a test track inside a sports car from 10% to 80% in just four minutes and 37 seconds. And that's despite the UK heat wave and a slight problem with the car and other sort of various circumstances that weren't sort of lab conditions. So they're really excited about this because it is definitely something that makes that,
