Basic conditions for pulsed thermonuclear fusion systems are examined. Simplified Lawson and trigger criteria are derived for magnetically and inertially confined plasmas. Two radically different proposals for a fusion react r are described. In the first a plasma whose density is of the order of 1019 ions/cm3 is supposed to be confined by a slow massive liner, in the second a plasma of super-solid density is generated by a liner whose speed is about 108 cm/sec. A remark on economy of such single-shot devices is made.
