I don’t believe having a working prototype is enough.
If there is no solid theoretical framework to explain it there will be no support from other scientists – no serious scientist wants to investigate a “Perpetual mobile”, even if it has fusion attached to it.
And if the scientific community will not be interested, then the public, government and serious investors will not be as well.
Imagine having a working prototype and no funding, no interest and no legislative support.

And many things can happen until 2013 – what about the buss factor for this project?
How many people have to be hit by a bus now for it to fail? Is it more than 1?

I am happy there are other alternative approaches to fusion power being investigated even now, and if at least one of them succeeds then the other ones have a better chance as well.
