Fusion - bring the Sun down

The sunlight is harmful and dangerous? So let's bring the Sun down. No, not literally.

I talk about the energy of a fusion reactor of course. The time-frame is unresolved, bu the milestones are set. Currently the largest one being buit South of France in Cadarache (ITER) is still for experimental reasons. The amount of energy needed to trigger fusion will be far larger than the energy generated. But we know that the equation begins to tilt in favor of feasibility if a fusion power station is sufficiently large. The one in Cadarache will be around 500 MWatt at full capacity.

Still, a commercilly feasible fusions station is some time away. At today's knowledge, the year this is expected is no earlier then 2025-2030, some 25 years away.
