SAI.TECH Global Corporation announced a major scale-up of its SAI NODE Marietta facility starting December 2023 and ongoing. This expansion demonstrates the company's dedication to enhancing the SAI NODE Marietta, the Company?s US R&D center that focused on advancing technology for high-performance computing liquid cooling and industrial-scale computing heat recycling. The expansion involves the strategic addition of 190 units of Bitmain S19 Pro+ Hydro bitcoin mining machines and 288 units of Bitmain S19 K Pro bitcoin mining machines.

The deployment of the 478 bitcoin mining machines and the underlying investment of approximately $0.9 million increased the hash rate capacity of SAI NODE Marietta by approximately 68 PH/s (petahash per second). With the Company?s additional deployment of bitcoin mining machines, it currently has approximately 150 PH/s operational hash rate for its self-mining operation, with an overall self-mining efficiency of approximately 27.3 J/TH. The newly added operation is to test the Company?s 2nd generation of TANKBOX, which is designed to further improve immersion cooling efficiency and flexibility of computing heat recycling.

Along with this expansion, SAI.TECH also announced an update about the SAI NODE Marietta as part of its ongoing efforts to provide sustainable and energy-efficient solutions to the bitcoin mining industry. The first SAI ULTIWIT System was completed and has been operating 24/7 since Nov. 2023.

It consists of a 1MW bitcoin mining WITBOX; a computing heat recycling, regulating, and supplying HEATBOX; and a floor-heated 5000 ft2 greenhouse or USERBOX. The SAI ULTIWIT system has been successfully demonstrated and can effectively recycle computing heat to support the greenhouse?s 24/7 operation even in severe winter weather conditions. With the success of the first SAI ULTIWIT System, the latest added miners will help SAI to develop new technologies of recycling computing heat for many other applications, such as fishery, aquatic centers, and industrial heating processes.

SAI will continue to work closely with OCEC, academic schools, national labs, and industrial partners, seek support from the local community, state, and federal government, and develop the Marietta site to become an advanced computing center ecosystem (ACCE).
