An energy accumulator includes a blast chamber, an explosive charge and a
detonator that explodes the charge within the blast chamber. A piston
forms part of the blast chamber and connects to an energy accumulator or
potential energy storage device such as a spring. When an explosive
charge is detonated, the piston is forced away from the blast chamber.
Energy from the displacement of the piston is captured in the energy
accumulator. The energy accumulator forces a fluid through different
devices requiring high pressure such as desalinators, ultra and micro
filters or chromatographs.
