Claim 11:
12. An energy-generating method comprising:
(A) submerging, in a liquid, a container that is configured to contain different volumes of a gas such that,
(i) when the container is in a first state, a liquid density corresponding to the liquid is greater than a container density corresponding to the container, and
(ii) when the container is in a second state, the liquid density is less than the container density;

(B) a cable hose that is in fluid communication with the container, wherein the cable hose is configured to unwind from a drum spool and rotate the drum spool as the container ascends in the liquid when the container is in the first state;
(C) transferring, via the cable hose, the gas into the container to bring the container to the first state in which the container ascends in the liquid; and
(D) unwinding the drum spool, as the container ascends in the liquid and thereby rotates the drum spool to generate electricity via an electrical power generator coupled to the drum spool, wherein the unwinding reduces a length of the cable hose wrapped around the drum spool.
