Experimental magnetic confinement facilities have recorded extended plasma stability at operational temperatures exceeding 100 million degrees Celsius. Private equity and venture capital investment in nuclear fusion enterprise startups reached $1.2 billion over the preceding four quarters.
Materials Science Bottlenecks
Sustaining continuous power output requires specialized plasma-facing materials capable of enduring intense neutron bombardment without physical degradation. Advanced tungsten alloys and liquid-metal wall shielding are currently undergoing initial pilot-scale trials.
