This is one of the comments in the "Nuclear fusion reactor at the Princeton Plasma Physics Lab".
With just $4M instead of $94M a more promising nuclear fusion reactor concept could be operationalized for net energy gain in less than one year.
Conceptually, it has been redesigned to be the most energy-efficient fusion reactor ever. Effectively, a clean, safe, dense and environmentally friendly power source to supply the world's energy needs, with no greenhouse gases, no long-term radioactive waste, low thermal waste, no large land areas, no environmental impact, no interruptions by the weather or time of day, no nuclear meltdowns and no proliferation. It is to be the ultimate energy source, an affordable answer to the world's energy problems; the right path to a more sustainable, peaceful and prosperous future for our planet. Potentially, now fully based on phased standing waves, the CrossFire Fusion Reactor can produce directly and efficiently an enormous quantity of electricity with less cooling water than conventional thermal power stations, releasing only the non-radioactive, non-corrosive, inert, and safe helium-4 gas.
