Who knows, commercial fusion power might actually be less than 50 years away now. LOL.
Edit: Do keep in mind that this stuff doesn't have to be the efficiency of the Sun because the Sun is actually quite inefficient and takes millions of years for the heat to get from the core where it is fused out into the galaxy. They have to be hotter than the temperature of the Sun and more efficient.

That is exactly what we want, a controllable much slower reaction to release a reasonable amount of energy at a time... The sun.
