Fusion is simple process...its the production of a facility to provide enough scale so as to produce economically viable reality is the hard bit.
Really interesting stuff...and definitely a solution that will enable a tiny amount of fuel to provide energy for all virtually free once up and running

In September 2013 the NIF was widely claimed to have achieved a milestone in controlled fusion, by successfully initiating a reaction that resulted in the release of more energy than the fuel absorbed. However, reports shortly after[104] indicated it was still far short of creating a self-sustaining reaction. Nonetheless, work published in January 2014 confirmed that more energy was being released — even if only for a fraction of a second — than was require to produce that release.[105] The process will need to be made more efficient to yield commercially viable amounts of energy.[106] In 2013, The Lockheed Martin's Skunk Works announced the development of a high beta fusion reactor they expect to yield a functioning 100 megawatt prototype by 2017 and to be ready for regular operation by 2022.[107][108] On March 5, 2014, Jamie Edwards became the youngest person ever to achieve fusion, building a version of the Farnsworth Fusor. He was 13 at the time, turning 14 the following weekend.[109] He was funded by his school, Priory Academy, on a small budget of around £2000, after being turned down for funding by several institutions. For this feat, Jamie received a letter from his royal highness, the Duke of York.[110]
