If you've been following my posts on fusion power, you'll know that I've been tracking nine alternative fusion reactor designs.
I do check the news semi-regularly to see what's new, and due to the fact that almost nobody anywhere is investing in fusion power research, there usually isn't much to be found. However, on today's search, I found good news. The US Department of Energy’s Princeton Plasma Physics Laboratory (Princeton was Dr. Einstein's old hangout) is now planning to move ahead with a spherical tokamak design, which, due to being shaped more like a cored apple than a doughnut, will be about half the volume of a tokamak (click here for link).
Now, I suspect that Mr Trump plans to take us back to the stone age in science, in which case, this project could be at risk (thankfully, there are nine others).
I do favour government funding of fusion power research, as the trillion dollar plus investment is and will remain a barrier to entry in the marketplace, and basic science is one of the areas where government spending has often produced positive results (the government did bring us the internet and almost every basic advance in computer science, not to mention the space program, multiple lifesaving medical treatments, etc.).
On the private side, Lockheed Martin has a great little compact fusion reactor design, but I don't think it's a funding priority there either --- they've published nothing since 2014.
