Problems solved by technology

[0003] However, there are still many deficiencies in the existing test technology for simulating the energy conversion of ocean temperature difference: 1. The cost of deep-water sea trials for the prototype of ocean temperature difference energy generation and underwater buoyancy drive system is extremely high; 2. Due to fluctuations in ocean hydrological conditions and temperature conditions, T
