A system of transferring the intangible gravitation to liquid's potential energy was disclosed recently. This system has shown that the intangible gravitation is not just a kind of force; it is also a kind of renewable energy that is harnessable. The theoretical foundation of this system is Pascal's principle; an important physical principle that has existed for more than three hundred years long. From theoretical aspect, this system can generate energy as much as a large multiple of the input energy. Yet, from practical aspect, this system needs energy to support its initial setup and followed running. In other words, it can't use the generated potential energy to self-supply the required energy. Therefore, from economical aspect, it is not clear if the energy generated is still profitable if the cost of the required energy is taken into consideration. In this paper, a potential energy regenerating system which not only can generate the liquid's potential energy but also can use the generated potential energy to self-supply the required energy while running will be introduced. This new system is fueled solely by the gravitation and can repeatedly perform the processes of the potential energy's generating.
