Secret of infinite energy explained
in the SMALL town of Livermore, California, sits the National Ignition Facility. Inside, scientists are busy constructing an artificial sun. Why? To ensure you need never worry about the electricity again.
It’s all possible thanks to Doc Brown’s favourite pastime: nuclear fusion. Optical lenses amplify a weak laser pulse (a billionth of a joule) to create a 500 trillion-watt laser to be directed through 192 beams and aimed at this Cerebro-like chamber. Sitting casually inside is a fuel capsule no bigger than a pea, warming up to 100 million degrees – that’s hotter than the sun’s centre – and becoming highly compressed, fusing its atoms together.
Fusion’s major flaw in the past has been that it requires an input of more energy than it created. But no more, apparently, as the NIF will deliver 100 times the energy needed to ignite it when operable. Race you to the plug… lasers.llnl.gov
