I have heard of efforts in India and China to develop and build out nuclear fission plants, though I do not know the scale of these plans. However, even ITER (the largest fusion project right now) has a budget of only $10-20 billion. I have high hopes for ITER, but even that has been protested by anti-nuclear organizations such as Greenpeace. I worry that fusion, despite its many advantages, may be stalled or stopped in the same way fission has been. If we cannot solve this issue with a currently-available zero-emission power source, I just cannot see how a new one based on the same principles can succeed.
