The just-achieved ability to get more energy out of a controlled fusion process than was put into the process is a tremendously positive step in generating power for our economy.
Some questions arise, though, that want answers before this achievement can be brought to actual, economic, widespread fruition.
- What is the efficiency of released energy capture? If the energy actually captured is less than the energy input, the process (so far) wouldn’t seem economically feasible.
- How long did the test last—not so much in terms of time, but over how many hydrogen fuel “pellets” in the stream fed into the process?
