with current science technology and scientists, when can we expect to see?

Fusion Hot and Cold

Hot: Very soon we will have a controlled, sustained nuclear fusion reaction that will produce more energy than it takes to get it started. But it may be decades before cost effective commercial application – if ever. But if it does pan out, our electrical generation worries are over, not to mention an end to the high environmental impact of Nuclear fission, coal, gas and oil power generation.

Cold: 20 years ago a pair of renowned chemists ruined their reputations and careers by claiming to have created a safe, energy-producing, fusion reaction in a table top apparatus. If that had panned out not only would we have an end to fossil fuel use and ‘dirty’ nuclear fission, but it would far far cheaper than any thing we could do with ‘hot fusion’. But no one could reproduce their results and their claims were discredited. Or were they? It turns out they may have been on to something real and a lot of labs are working on it. Several reputable labs claim to have measured net positive energy output in these ‘cold fusion’ experiments. But none of them can do it repeatedly and consistently. So the jury is still out, but there just might be something there that could change everything.
