Touring Dyson's ideas factory

Most of Dyson's big ideas (including its recent hair dryer) originated from its UK HQ, hidden away in the quiet English countryside.

Samsung isn't the only company that's struggled recently with faulty batteries. We've seen similar issues with hoverboards, a Tesla Model S and plenty of electric skateboards. Let's hope those non-exploding lithium-ion batteries get here soon.
