It's fun to demonstrate just how difficult nuclear fusion is. As part of an astrophysics course I taught, we worked out how much power each cubic metre of the Sun's core generates. It's about 100 W.
In context, the metabolic rate of a cat is about 2 kW per cubic metre. (one cat has a volume of about 5 l, and a metabolic rate of 10 W).
If stars have difficulty, no wonder it's taking us a lot of effort.
