A power plant needs about ten times higher gain, which is limited by fluid instabilities, mixing of shell material into the fuel and uneven drive.","title":"Inertial confinement fusion at high gain","topic_ref":null,"why":"Inertial fusion power plants need target gains of roughly 30 to 100, far above what has been achieved."},"attested":{"attestation":{"batch":null,"client_id":null,"id_token_sha256":null,"kind":"platform"},"record_hash":"35a789f90b244cd8706c293912ba9a34c2bdead179625fc1aecf24efeea02394","schema":"pubphys.attested/1"},"envelope":{"attested_hash":"788f089c06c7f94cd2fe8061290f1b8754b864ad79422c5cb873e376028c0338","platform_signature":{"key_id":"c6afc19b31429869751f06879c75cd64ea92654423d15b44be775bf1310a60da","sig":"dYY_FobiH0bNNelk2FFhZpniqIxZUER60R3_pZGC-CPbD1Mfl-3E8lXSU9Q4rLLmDtIQB3WbejMhrk1IeBRkAw"},"schema":"pubphys.envelope/1"},"record_hash":"35a789f90b244cd8706c293912ba9a34c2bdead179625fc1aecf24efeea02394","leaf_index":301}
