<p>A geothermal energy extraction system (100;1000) comprising a conduit (200; 1020, 1030) within an excavated bore(10; 1010). The conduit(200; 1020, 1030) comprises a substantially vertical descending feed section(20; 1020) and an ascending extraction section(30; 1030). At least part of both vertical sections (20;1020, 30; 1030) are located in a geothermal zone (300; 1080) below surface. A plurality of branches(600; 1070)extending from the bore in the geothermal zone (300;1080). The branches (600;1070) are each filled with thermally conductive material.</p> |
