Our future health, happiness and economic well-being depends on producing plentiful, inexpensive, carbon-free energy that is available 24 hours/day, worldwide. Coal, oil and gas supply over 80% of the world's energy but cause pollution and add to global warming. Renewable energy, such as wind and solar, may not be able to supply enough energy. Ed Moses and the National Ignition Facility have an idea that could change everything-fusion energy-unlocking the force inside the nucleus of hydrogen that powers the sun and the stars. Learn what it will take for fusion power to become a reality in the next few decades. Series: "Lawrence Livermore National Lab Science on Saturday" [Science] [Show ID: 20233]
