Methods and systems for imploding a liquid liner

A liquid liner implosion system for forming a cavity in a liquid liner and collapsing the cavity by imploding the liquid liner, the system comprising:

• (a) a vessel having an outer wall;
• (b) a rotating member inside the vessel and rotatable about a rotation axis, the rotating member comprising
• a first end and a second end along the rotation axis;
• an inner surface defining an interior volume and curving with respect to the axis of rotation;
• and
• a plurality of curved passages each having an inboard opening at the inner surface and an outboard end, wherein a curvature of each passage is a function of a distance between the outboard end of the passage and the first or the second end, and wherein one or more of the passages have an outboard end in a vicinity of the first or second end and curves in three dimensions from the outboard end to the inboard opening in a direction towards a central region of the interior volume;
• (c) a rotational driver operationally coupled to the rotating member to rotate the rotating member;
• (d) a liquid medium in the rotating member, the liquid medium at least partially filling the curved passages and forming a liquid liner when the rotating member is rotating, an inner interface of the liquid liner defining a cavity coaxial with the rotation axis;
• and
• (e) an implosion driver engageable with the rotating member to change the acceleration of the rotating member and cause the liquid liner to implode towards a central region of the interior volume, thereby collapsing the cavity.
