Fusion Reactor Sets New Endurance Record
!splut writes "Fusion fans out there will be interested to know that an experimental French fusion reactor has set a new duration record of 210 seconds. Most fusion reactor research works (or tries to) by containing and compressing a quantity of plasma via an electomagnetic field in a toroidial chamber. Fusion energy could potentially provide a a clean, efficient, and virtually inexhaustible source of energy, but fusion reactoins have proven difficult to contain and control, so this is a significant achievement."
What needs to be understood is that they've managed to use a fusion generator to generate electricity. However, they've never managed to create electricity in a useful fashion.
As it stands, they can create an efficient reactor that is not self-sustaining or a self-sustaining reactor that is not efficient. In other words, the former uses very little outside power, but isn't stable and ceases to function. The latter is more stable, but uses more fuel than conventional means.
Fusion power is not a pipe dream. Just as conventional power reactors have been improved over time to produce electricity more efficiently, so will fusion reactors eventually be improved to the point where they're useful. Will it be in the next decade? It may well be, but regardless of when it will happen, it will happen.
