A power plant, on the other hand, produces steam at high temperature and pressure for generating electricity. (helmholtz-berlin.de)
It has also been found that under some conditions of turbulence, when lithium is carefully injected, temperature and pressure of the plasma increases and the condition becomes ideal for fusion to occur. (power-technology.com)
Of course, the cores in the stars are much bigger and also stay at those extreme temperatures and pressures for much longer. (sciencemag.org)
