Very cheap energy means cheap war and lots of it. This could be bad.

If they can manage to build what they envision we will have tanks with with laser weapons.

Autonomous drones with facial recognition and laser weapons, rather.

So, they've come up with a way to make a fusor that produces more energy than it consumes? Also, I'd be interested in knowing what kind of scram mechanism they develop. If the superconductors were to fail, the expansion of the plasma would be catastrophic, right?

It certainly wouldn't produce a runaway fusion reaction, if that's what you mean. A hot plasma would dissipate pretty quickly once confinement fails, so the only energy would be that in the plasma itself. Might be bad for whoever is in the room, but probably not the county.

Meanwhile, work on an actual fusion reactor continues; http://www.iter.org/newsline/-/2020

From the article:

"Until now, the majority of fusion reactor systems have used a plasma control device called a tokamak, invented in the 1950s by physicists in the Soviet Union. The tokamak uses a magnetic field to hold the plasma in the shape of a torus, or ring, and maintains the reaction by inducing a current inside the plasma itself with a second set of electromagnets. The challenge with this approach is that the resulting energy generated is almost the same as the amount required to maintain the self-sustaining fusion reaction."

> U.S. submarines and aircraft carriers run on nuclear power, but they have large fusion reactors on board that have to be replaced on a regular cycle. sigh To the extent this is true I suspect those "large fusion reactors" are tuned not so much for generating electricity and a great deal for annihilating whatever the carrying missile is pointed at. But never mind fuzzy thinking at Reuters right now. This is amazing…

From what I've heard, the reactor actually outlives the ship, no?
