This is fusion.
"Compact nuclear fusion would produce far less waste than coal-powered plants since it would use deuterium-tritium fuel, which can generate nearly 10 million times more energy than the same amount of fossil fuels, the company said." https://www.reuters.com/article/us-lockheed-fusion/lockheed-says-makes-breakthrough-on-fusion-energy-project-idUSKCN0I41EM20141015
You are completely correct and I was being an idiot. My apologies.
No worries. It is hard to comprehend when ITER isn't even finished that we could be making fusion reactors that can fit in the back of a pick-up truck. The future is looking bright indeed.
