Overall there many interesting projects with decent funding. Most are being more careful about making specific timeline promises. Molten Salt fission could deliver on most of the nuclear fusion clean energy and low-cost energy claims with what appears to be lower technical risks and no scientific uncertainties.

General Fusion is raising hundreds of millions for 70% scale demo system to be completed around 2023. The next system after the 70% scale system will be a full commercial system. They have a pulsed system without the need for plasma containment. General Fusion feels if they can prove out end to end power generation that scaling to higher energy return will not be a hurdle.
