Stellarators offers a cleverer approach to fusion power, due to their complexity, usually they get more attention for its looks then to its actual ingenuity.

Tokamaks on the other hand, are by far the most studied type of fusion reactor in the world. So much so that the European union is investing billions of euros, in one of the largest machines ever built by man, the ITER project.
There are many other ideas being explored in terms of magnetic and inertial confinement. While a lot of them are promising concepts, energy production is still a big question mark.
