Ben Welter - Tuesday, July 11, 2017

U.S. patent application 20170191469 (applicant Atlas Copco Airpower NV, Wilrijk, Belgium):

"An energy cell that is provided with a pressure vessel with two chambers separated by a membrane, respectively a first chamber filled with a phase-change material [23, at right] and a second chamber filled with hydraulic fluid, whereby this energy cell is provided with means to be able to heat and cool the phase-change material alternately, coupled with a volume change, whereby the second chamber is provided with a passage that acts as an input and/or output for the hydraulic fluid, whereby the membrane is stretched elastically upon a phase change whereby the volume in the first chamber increases."
