Benefits of technology

This patented technology provides a way for generating electricity from salts with different electrification levels without requiring any external equipment like pumps or motors. It also improves accuracy when measuring voltages due to increased conductivity caused by adding certain substances on top layers of both types of solutions.

Problems solved by technology

This patented describes an apparatus that generates electrical current based on differences in specific properties or states associated with certain substances found naturally at varying levels within various environments like oceans. These techniques involve converting soluble molecules called cathodium ions (Na+) into mobile ones called hydrogen gas (H2) inside one solution containing calcium chloride (CaCl2) while redoing another solution containing sodium sulfate (S02)). By doing this, these processes create excess voltage when compared against their own original value.
