Yeah, the plan for ITER is to produce 500MW over 1,000 seconds, with an input power of 50MW (and 0.5 grams of deuterium-tritium fuel). The current record is, like, 10 seconds and no one has broken even on input/output power... Edit: Ah, actually the current record is less than 1 second: http://en.wikipedia.org/wiki/ITER#Background http://en.wikipedia.org/wiki/ITER#Background
