Nuclear fusion promises a green and infinitely renewable supply of energyif we can harness it. Fusion happens all the time inside the sun. But to recreate the process on Earth, we must control incredibly hot, chaotic matter in an exceedingly dense state. Prototypes of several different fusion-reactor designs are being tested around the world. The National Ignition Facility (NIF) at Lawrence Livermore National Laboratory in California, for example, uses lasers to spark fusion in a small pellet of fuel.
General Fusion, a Canadian nuclear fusion energy startup, announced today that it had been thrown a lifeline in the form of $22 million in fresh funding. The company had laid off at least 25% of its employees in May in a bid to shore up its stretched finances. At the same time, CEO Greg Twinney wrote an open letter pleading for funding. The additional cash will give General Fusion some breathing room, though not much.
In December 1942, the first experiment to achieve a sustained nuclear reaction occurred beneath the University of Chicago in a reactor called 'Chicago Pile 1.' This marked confirmation of Szilard's theoretical idea of nuclear chain reactions, where a reactions can continue and sustain itself.
