Type 2 perpetual motion machines help humans achieve stellar civilization and eliminate it
Humans can only approach planetary level civilizations now. The following image shows the existence of type 2 perpetual motion machines, making travel and life within the solar system easier and safer.
The design of this perpetual motion machine has been recommended by two PhDs. If you support it, please provide a 'recommendation'.
What is the significance of the perpetual motion machine, the Russo Ukrainian War, and possibly the Third World War? Scientists should take on their own mission, and the key is that perpetual motion machines are indeed analyzable.

Dear Bo Miao.
You can write anything. Paper will endure everything.
The first law of thermodynamics dU = TdS - pdV is sufficient to understand temperature T as the rate of transfer (flow) of energy, and pressure p as the rate of transfer of momentum from one body in contact to another.
Therefore, you will never, under any circumstances, get a positive value if you subtract a large value from a small value.
Sincerely, Dulin Mikhail.
Your formula 'dU=TdS - pdV', where dS is meaningless. The cycle I designed has been implemented: the dual gas Carnot cycle achieves heat transfer from low temperature to high temperature without consuming external energy. The entropy S is no longer meaningful. Note the formula:
Q (high temperature)=- Q (low temperature)
