In 2022, the National Ignition Facility in the USA was briefly able to generate more energy than required to run the reactor. This is an experimental reactor, and the yield is small, but it shows that fusion can work. Since then, reactors in China and France have been able to sustain fusion for a few minutes.

Anyone knowing entropy realizes the challenges and losses of that.

Yes, you need a massive amount of concentrated energy, and as far as I know only nuclear reactors can do that.
