This project aims to leverage the Qiantang River's natural cooling source and tidal energy to build China's first integrated platform combining "computing temperature-controlled hosting + green energy output + extreme environment R&D". Utilizing the independently developed "Dual-Timescale Adaptive Depth-Keeping Suspension" technology, the design achieves a comprehensive PUE ≤1.03, saving over 30% energy compared to traditional data centers.
Total investment is approximately ¥38 million, with estimated average annual net revenue exceeding ¥20 million and a static payback period of approximately 1.9 years. The project is not only an innovative practice in green computing but also a demonstration of digital RMB smart contracts in infrastructure development.
