5. A method for obtaining internal energy from liquid by utilizing buoyancy and features of doing work, comprising steps of:
a) disposing an inner body inside a shell body and to a first side of a sealed liquid room of the shell body, wherein the inner body is sealed by a sealing strip, a density of liquid equals to a density of the inner body, a second side of the shell body, which is a gas communicating room, communicates with atmosphere;
b) inputting the liquid having a pressure P into the sealed liquid room of the shell body through a liquid entrance, wherein the liquid puts a horizontal force F on the inner body, the inner body is driven to rotate towards the gas communication room of the shell body by the horizontal force F of the liquid, a weight of the inner body does a work Wg under gravity after being free from buoyancy of the liquid, which means that the work is done in a rotation form in a gravity field, an axle spins with the inner body, a work doing progress is finished after the inner body rotates from the sealed liquid room to the gas communicating room, wherein a work Wp done by the inner body to an outer system and the Wg is inputted into an energy transformer;
c) releasing the liquid in the sealed liquid room via the liquid entrance after the liquid finishes doing work to the inner body, wherein energy Wl is obtained when the liquid is released, and the sealed liquid room changes into a new gas communicating room, the energy Wp is fed back through the energy transformer to the liquid released for obtain energy Wl+Wp=W to restore energy of the liquid, an energy loss of the liquid is paid back by the energy Wp, the energy of the liquid remains constant; and
d) closing the sealed liquid room for forming the new gas communicating room and opening the gas communicating room for forming a new sealed liquid room, inputting the liquid, which has restored the energy, into the new sealed liquid room for doing work to the inner body in the sealed liquid room, wherein the inner body rotates by gravity after returning into the gravity field and obtains another energy Wg again, repeating steps above again and circularly.
6. An energy transmitting device, comprising:
a shell body having an inner space,
a first liquid entrance and a second liquid entrance mounted at a bottom portion of said shell body, wherein liquid is inputted or outputted through said first liquid entrance and said second liquid entrance,
an axle mounted inside said inner space and capable of communicating with an outer system, wherein the outer system is driven by said axle when said axle rotates,
an inner body provided inside said inner body, wherein a bottom portion of said inner body is connected to said axle and is capable of rotating with said axle synchronously when driving by the liquid or a weight of said inner body,
a sealing device mounted between said shell body and said inner body for dividing said inner space into a first room and a second room, wherein when said inner body rotates, the liquid in said first room does not flow into said second room, and vice versa, the liquid in said second room does not flow into said first room,
a pump driving by an outer power resource, comprising a first communicating tube and a second communicating tube connected to said first liquid entrance and said second liquid entrance respectively, wherein said pump is capable of driving the liquid into said shell body,
a first valve and a second valve mounted in said first communicating tube and said second communicating tube respectively, wherein said pump is capable of driving said first valve and said second valve to open or close for determining that the liquid is inputted into said first room or said second room, and
a barrel connected to said pump for storing the liquid, wherein when said inner body is in said first room, said pump drives said first valve to open and said second valve to close for driving the liquid in said barrel into said first room, said inner body is driven to rotate by a pressure of the liquid and then by said weight of said inner body as well as the pressure of the liquid for rotating into said second room, said pump stops after said inner body rotates into said second room and the liquid returns to said barrel, said pump works again and drives said first valve to close and said second valve to open for driving the liquid in said barrel into said second room, said inner body is driven to rotate by the pressure of the liquid and then by said weight of said inner body as well as the pressure of the liquid for rotating into said first room, said pump stops after said inner body rotates into said first room and the liquid returns to said barrel, repeating progresses above again and circularly in such a manner that the outer system is driven by said axle.
7. The energy transmitting device, as recited in claim 6, wherein said sealing device is connected to a position dividing said shell body into equal halves.
