We have ‘ignition’: Fusion breakthrough draws energy gain

U.S. scientists have achieved “ignition” — a fusion reaction that produced more energy than it took to create — a critical milestone for nuclear fusion and a step forward in the pursuit of a nearly limitless source of clean energy, Energy Department officials said Tuesday.

Nuclear fusion, the process that powers the sun and other stars, occurs when two atoms’ nuclei collide under extreme temperatures, causing a reaction that can generate incredible amounts of energy with few environmental costs.

The latest step toward pollution-free power has the potential to transform the energy sector, perhaps decades from now, but some companies are already positioning themselves to benefit.

Energy Secretary Jennifer Granholm said on Tuesday that scientists at the Lawrence Livermore National Laboratory in California had made “a tremendous scientific breakthrough” in their tests of nuclear fusion, the reaction that powers the sun. While prior efforts to achieve fusion—combining two hydrogen atoms to produce helium in a reaction that produces energy—consumed more energy than they released, the Livermore scientists flipped the balance.

Basically the sun in a box. To talk about what this may mean in the long term implications I’m joined by Michael — CEO of T 80 technologies, the private fusion energy company. Michael, great to have you on the show. You have the tough job here of explaining this to our audience. In layman’s terms, explain exactly what’s being achieved here?
