There is increasing interest in developing superhot (>400^oC) geothermal systems to produce electricity, because conventional geothermal (200 – 300^oC) is not efficient. For drilling depths that are currently feasible, superhot conditions only occur near magma. Therefore, the relationship between magma and geothermal zones is very important. Evidence from the few geothermal wells that have reached magma, together with consideration of changes in rock properties at high temperature, suggest that the interval between circulating magma and circulating geothermal fluid may act as an insulator, a thin wall containing a hot liquid like in a thermos bottle. If so, puncturing or cracking the wall by drilling will make magma’s extreme energy available. To develop this new source of energy, materials not previously used in the geothermal industry and a sustained collaborative project effort are required. However, the basic information needed to move forward is attainable at modest cost by drilling to obtain continuous rock samples and measurements of conditions adjacent to magma.
