There are over 400 world-wide working nuclear reactors, there are proven to work, and been improved for over 50 years. All of them cost in range of couple billions, and time to build one from the start is in range of 10 years.
There is not a single working fusion reactor, and none is even close to be working continuously, and even dreaming to be used as a power source, not just a research device. We are not even at the level of Chicago Pile 1. But sure, there are some guys that will do that for 65 millions in 6 years. Thank you EU for dumping 35 millions in this cleaver project. Thank you for NOT giving this money to the real science, like ERC grants, where there is such a tough competition, and a lot of very good project do not get funding.
