We have developed a super-efficient, fast, high-throughput method for searching high-Tc hydride superconductors. We introduce new "metrics" strongly correlated to electron-phonon solid coupling and Tc, but it is much quicker to calculate them. We have searched more than 100,000 binary hydride and metal-borates superconductors using our new method and discovered many new high-Tc systems. Our work will not only significantly accelerate the discovery of new high-Tc conventional superconductors but also give a detailed understanding of important factors that yield superconductivity near room temperature at extreme pressures.
