ArmyOfAll

I've been away for a couple of weeks, I just wanted to say thank you all for taking the time to answer my basic questions in such a comprehensive manner. I now know a little more about not only my own question but the difficulties and possibilities. Cheers.

I am an ordinary guy, no academic, I am just curious about something. At present we can't get a self sustaining reaction for long, this much I understand. And I realise its of no practical use, but can we sustain a fusion reaction if we sustain the input power (ignition)? I realise the output would be lower thus rendering the point of it useless. Cheers.
