MicroBT, a leading manufacturer of Bitcoin mining rigs, is focused on meeting the demand for upgraded power sources in bitcoin mining. In an interview held at Bitcoin 2023 in Miami Beach, MicroBT’s COO, Jordan Chen, highlighted the company’s commitment to developing solar power mining solutions. According to Chen, “Solar power is a perfect power source for bitcoin mining, in terms of decentralization and sustainability.” He further explained that MicroBT is working with value chain partners to provide a mature solution that uses solar power for mining around the world.
Chen explains how to adjust the voltage and frequency of MicroBT’s Whatsminer rigs to adapt to changing solar power. He stated, “The mining machine must adapt to the power changes to continue mining throughout the day with different voltages and working frequencies.” Chen emphasized that this dynamic adjustment only accounts for about “1% to 2% efficiency compared to the traditional shut-down-and-reboot method,” ensuring continuous mining operations and optimizing the income.
Discussing the cooling methods of the new Whatsminer M50 series, Chen provides insights into the benefits and unique features of each method. He explains, “Air cooling dissipates heat through fans, while hydro-cooling uses water-cooling pads that eliminate the need for fans, heat sinks, and provide longer life. .” Regarding the immersion cooling, Chen emphasized its advantages, saying, “It is absolutely dust-free, no exposure to harmful air, low noise and longer life.”
Chen shared MicroBT’s focus on heat utilization scenarios, saying, “The heat generated during the mining process will be transferred to the external heating loop through a heat exchanger.” He further explained that the heat recovery ratio can be as high as 95%. Chen highlighted MicroBT’s collaboration with customers in various applications, such as providing heating services to communities and generating steam for industrial uses such as food processing.
When discussing MicroBT’s vision for the future of Bitcoin mining, Chen highlighted their commitment to exploiting renewable energies and maximizing the reuse of heat generated during mining. He stated, “Our vision is to allow bitcoin mining to make a greater and greater positive contribution to society,” with a focus on reducing carbon emissions and carbon footprint.
