Vanguard Supercritical

Vanguard Supercritical

Water above its critical point, 45% thermal efficiency, and no steam generator. Announced, not yet open.

Above 22 MPa and 374 °C water stops distinguishing between liquid and gas, which means a reactor can drive a turbine directly with no steam generator and no boiling crisis to design around. Thermal efficiency rises from roughly 33% to 45%. The unresolved problem is materials: very few alloys tolerate supercritical water, radiation and time simultaneously.

No payment processor is connected. The commitment flow runs end to end, through amount, agreement, signature and receipt, and records a simulated position rather than a charge.
