Techniques are provided for extracting geothermal energy, by providing salt into a well shaft that ends in a chamber in the Earth surrounded by a source of geothermal energy. The salt melts and heats up to the temperature within the chamber. The hot molten salt is then extracted and the heat from the molten salt is used as a source of energy to generate electricity or drive an industrial process. The salt can be re-used once the heat is extracted in a closed-loop system. According to some techniques, the salt is conveyed down the well by a pneumatic conveyer system or in other cases by using a mechanical system, such as a screw drive. Once returned to the surface, the molten salt can be used to heat graphite blocks for energy storage or be stored and transported to remote locations to extract the heat energy.

Thermal Moisture Enhanced Gradient Strata (TMEGS) for Heat Exchangers optimizes the performance of energy flows for building heating, cooling, hot water, and industrial processes. TMEGS are temperature and moisture control layers which reduce the cost of closed loop ground heat exchangers and increase heat exchanger performance by improving energy transfer between solar, geothermal, process heat and renewable energy exchangers. Circuit optimized thermally active building structures (COTABS) configure heat exchangers and thermal energy strata for application specific requirements. TMEGS integrated with COTABS is a scalable and interoperable carbon-free, planet friendly architecture for net zero energy buildings. Embodiments include the use of recycled materials, waste tire derived aggregate, nanofluids, phase change materials, cathodic protection, and integrated microprocessor and client-server controls.
