In one aspect, reverse electrodialysis systems are described herein having constructions operable to reduce membrane stack resistance, thereby requiring significantly less membrane surface area for meaningful electrical power generation. A reverse electrodialysis system described herein comprises an anode and cathode adjacent to a membrane stack, the membrane stack comprising alternating anion and cation exchange membranes defining diluate and concentrate ionic solution compartments, wherein an ion exchange medium is positioned in a diluate compartment.

A pistol grip spring compressor system including a spring lock unit, an actuator assembly, and an anvil module such that the spring lock unit secures a valve spring coil of a valve spring unit from an internal combustion engine in a fixed position relative to a frame element to permit an anvil, provided by the anvil module and positioned against a valve spring retainer of the valve spring unit, to maintain compression on the valve spring while the valve spring unit is separated from an automobile internal engine combustion block.
