MicroBT, a leading manufacturer of bitcoin mining rigs, is focused on addressing the need for advanced power sources in bitcoin mining. In an interview held at Bitcoin 2023 in Miami Beach, Jordan Chen, COO of MicroBT, emphasized the company’s commitment to developing solar power mining solutions. According to Chen, “solar energy is an ideal power source for bitcoin mining, both in terms of decentralization and stability.” He further explained that MicroBT is working with partners along the value chain to provide a mature solution that harnesses solar energy for mining around the world.
Chen explained the adjustments of voltage and frequency in MicroBT’s Whatminer rigs to adapt to changes in solar power. “Miners have to adapt to power changes in order to mine with different working voltages and frequencies throughout the day,” he said. Chen stressed that this dynamic adjustment only costs “1% to 2% efficiency” compared to the traditional shutdown-and-reboot method, “ensuring continuous mining operations and optimizing revenue.”
In discussing the cooling methods in the new WhatsMiner M50 series, Chen provided an overview of the benefits and unique features of each method. He explained, “Air-cooling is taking heat away via a fan, while hydro-cooling uses water-cooling pads that eliminate the need for fans, heat sinks, and offer longer lifespans.” Regarding immersion cooling, Chen highlighted its benefits, saying, “It is virtually no dust, not exposed to corrosive air, low noise and long lifetime.”
Chen shared MicroBT’s focus on heat usage scenarios, saying, “The heat generated during the mining process will be transferred to an external heating loop through a heat exchanger.” He further added that the heat recovery ratio can be up to 95%. Chen emphasized MicroBT’s collaboration with customers on 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 stressed its commitment to leveraging renewable energy and maximizing the reuse of heat generated during mining. “Our vision is allowing bitcoin mining to make a larger and larger positive contribution to society, with a focus on reducing carbon emissions and carbon footprint,” he added.
