Here is another article that does actually mention the other energy requirements

Energy gain in this context only compares the energy generated to the energy in the lasers, not to the total amount of energy pulled off the grid to power the system, which is much higher. Scientists estimate that commercial fusion will require reactions that generate between 30 and 100 times the energy in the lasers.

I just came across this link on social cooling from another post a few days ago. The amount of information that can be gathered on you is frightening. I just want to be able to control my own data rather than it being taken from me.

Edit: This was also a super interesting read on what privacy actually is as a concept as well as analyzing the social balance of privacy and security.
