I am not of the philosophy that if it hasn't been done it can't be done. Engineering challenges are challenges, not insurmountable walls. I still have hope for fusion. It hasn't been done yet. Should we just quit trying?

How much time do you want to spend on why hydrogen fusion won't work? 3 words: High Speed Neutrons.
Instead of trying to go for fusion, we could concentrate on making fission smaller, cheaper, faster and safer. And then go for the brass ring: Matter to Energy. With fully developed fission, we have roughly 500-1000 years...
