C3 prototype (nT-Tao)

nT-Tao is an Israeli compact fusion company developing a pulsed high-density magnetic-confinement system; its C3 prototype achieved first plasma in January 2026. Its planned Compact Fusion System targets up to 20 MW of continuous electricity, and in September 2026 it signed an MoU with Orion Nuclear Energy to explore US deployments.

Current state

Notes

target output refers to the planned Compact Fusion System product, not C3. Secondary sources cite ~$28M total funding (Series A $22M led by Delek US); not verified from a primary source, so private funding raised not recorded. concept "Other" = pulsed compact magnetic confinement.
