Rapid response power conversion device

A method for extracting energy from an IC engine, the method comprising:

• providing a chamber having a piston, at least one fluid port coupled to said chamber for supplying fluid thereto and an out-take port, said piston and said at least one fluid port configured to provide a variable pressure to said chamber, said piston configured to reciprocate in said chamber between a top dead center position and a bottom dead center position, each reciprocation of said piston defining a cycle, said piston and said fluid configured to at least partially facilitate combustion to provide energy from said combustion in a combustion portion of said chamber;
• providing a rapid response component, said chamber comprising a first compartment and a second compartment with a divider portion therebetween, said first compartment including said piston and said second compartment including said rapid response component, said divider portion defining an aperture therein extending between said first compartment and said second compartment;
• positioning said piston to be in fluid communication with said first compartment;
• positioning said rapid response component to be in fluid communication with said second compartment;
• and
• causing a combustion in said chamber and enabling said rapid response component to draw at least a portion of said energy from said combustion.
