Great Balls of Fire

Click looks at alternative energy, as the team is at a small UK outfit which is trying to beat the big budget energy companies in creating fusion energy in the next decade. Fusion energy one day can supply the world with almost limitless clean energy. They then travel to India, visiting its largest solar panel farm to see how the country is trying to solve its energy crisis right now. Also in the programme the team visits a start up which is trying to change the way we donate to charities online, plus they go on a ride with the San Francisco Police Department which is trialling a new breathalyser that can detect cannabis use.
