It's a really complex machine and it hasn't been designed to produce any electricity yet. So it's a fusion experiment and not a power plant. The hope is that this device leads to another one which might be able to sustain operation and produce electricity. But how much will that cost? Will one be able to mass produce such a machine at competitive costs? Will we see larger and smaller designs?
