Abstract
An energy cell generates pressurized fluid for use as an energy source when a phase change material (PCM) changes from solid to liquid phase. The energy cell includes housing means holding the PCM, insulating means between the housing means and the PCM, heat exchanging means encompassed by the PCM, multiple pipe means, and multiple disc means, each provided with multiple aperture means and each encompassing a part of the pipe, and a centrally located bladder means with open end parts fixed to the energy cell, and which is flexible between the end parts. Each pipe means includes a heat transfer media. The PCM encompasses the pipe means and the disc means and is able to pass through the aperture means. The bladder means includes a hydraulic fluid flowing in and out through the open end parts of the bladder means and is affected by the PCM.
