Bitcoin could help unlock 2 to 4 terawatts of continuous clean energy by leveraging Ocean Thermal Energy Conversion (OTEC), a 150-year-old concept that turns the Earth’s oceans into a vast solar battery. OTEC works by using the temperature difference between warm surface water and cold deep seawater to drive a heat engine, generating consistent, renewable electricity. Bitcoin’s ability to monetize stranded energy makes it an ideal partner for scaling OTEC, while the technology’s access to limitless cold water offers an exceptionally efficient and ecological solution for mining. With over a billion people living near tropical coasts, this synergy could provide sustainable power and cooling infrastructure on a planetary scale.
