The present disclosure is generally directed to a method, system and an apparatus that includes a hollow canister including a top portion and a bottom portion, the top portion including a top opening and the bottom portion including a bottom opening. The hollow canister additional includes an inner compartment within the hollow canister, the inner compartment being porous to allow fluid transfer across the inner compartment, a neutral buoyancy device, a variable buoyancy device, and a thermoelectric module lining an inner portion of the hollow canister. The thermoelectric module generates electricity based on a temperature difference of between an interior temperature the hollow canister and an exterior temperature on a periphery of the hollow canister.
