Why Nuclear Fusion Could be a Clean-Energy Breakthrough

From an AP story by Doug Glass and Michael Phillis headlined “Why fusion could be a clean-energy breakthrough”:

The major advance in fusion research announced in Washington on Tuesday was decades in coming, with scientists for the first time able to engineer a reaction that produced more power than was used to ignite it.

Using powerful lasers to focus enormous energy on a miniature capsule half the size of a BB, scientists at the Lawrence Livermore National Laboratory in California started a reaction that produced about 1.5 times more energy than was contained in the light used to produce it.
