Main Question or Discussion Point
I know that to achieve fusion one has to satisfy the Lawson criterion. My question is: can fusion be achieved only by generating very high pressures but keeping the system at room temperature, or does it necessarily require a combination of both high pressures and high temperatures? If by some miraculous design one could apply a pressure of 1 Million Megabars to a tiny volume of D-T gas, would that be enough or are temperatures of millions of degrees also required? I can't find anywhere the data for the D-T reaction cross-section as a function of pressure but at room temperature....
