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.
