Geothermal Energy
★Exhibit Content: Causes of geothermal energy, principles of geothermal power generation, clean energy utilization ★Interaction: Mechanical + multimedia interaction ★Operation: Repeatedly pull and press the operating handle on the table with both hands to simulate the process of extracting and transporting underground cold water; observe the complete demonstration process of water circulation, steam generation, and turbine unit operation inside the stratum profile model; click the touch screen to watch the accompanying multimedia animation and systematically learn about the sources of geothermal energy and the complete geothermal power generation process. ★Exhibit Description: "Geothermal Energy" is a vertical science popularization exhibit under the theme of new and renewable energy, belonging to the energy and environment science popularization exhibition area, and is a recommended exhibit of the PopsciCat Exhibit Store. The exhibit adopts a Q235 cold-rolled steel plate integrated vertical sheet metal cabinet, with a transparent closed geothermal stratum profile simulation model arranged in the middle, a pull-press operating lever on the side, a touch screen on the top, and a mechanical transmission mechanism, PLC electrical control system, and multimedia industrial control host integrated inside the cabinet. The exhibit simulates the entire process of cold water entering the stratum, geothermal heating to generate steam, and steam driving the generator to generate electricity through manual mechanical linkage, combined with multimedia video explanations of the formation principle of geothermal energy and power generation technology, intuitively demonstrating the advantages of geothermal as a pollution-free, renewable clean energy. ★Scientific Principle: Geothermal energy mainly comes from the heat generated by the Earth's internal molten magma and the decay of underground radioactive materials. Only about 5% of shallow surface geothermal energy comes from solar radiation. Underground magma heats groundwater, and high-temperature hot water and steam are transported to the shallow surface along crustal fissures, forming exploitable geothermal resources. Geothermal energy is clean and renewable, with no exhaust pollutant emissions. As long as the heat extraction rate is lower than the replenishment rate of the underground heat source, geothermal resources can be sustainably recycled. The core principle of geothermal power generation is similar to thermal power generation. Underground high-temperature hot water and steam serve as the power source. First, geothermal heat energy is converted into mechanical energy of the steam turbine, and then the generator converts mechanical energy into electrical energy, achieving stable output of geothermal energy.

★Exhibit Content: Principles of hot dry rock geothermal energy extraction, complete geothermal power generation process ★Interaction: Electromechanical interaction ★Operation: Press the blue button, observe the cold water LED light strip in the stratum profile flowing downward; continue pressing the blue button, observe the lights of the hot dry rock extraction well model gradually lighting up upward; after the lights reach the top, the blue button turns off and the orange button lights up; press the orange button, watch the chimney device emit simulated smoke rings. ★Exhibit Description: This exhibit is a circular tabletop science popularization exhibit in the energy and environment exhibition area, and is a recommended exhibit of the PopsciCat Exhibit Store. The exhibit has two independent interactive operation units, allowing two visitors to participate simultaneously. In the middle of the exhibit table, there is a stratum profile model and an acrylic model of a hot dry rock extraction well. On the tabletop, blue and orange mushroom buttons are arranged, along with LED dynamic light strips and a voice explanation module. By pressing different buttons, visitors simulate the entire hot dry rock geothermal extraction process of water injection, underground heat storage, steam collection, and steam discharge through light animations, and with voice explanations, intuitively understand the extraction mode of geothermal resources. ★Scientific Principle: Hot dry rock geothermal extraction involves drilling into high-temperature rock bodies, artificially creating fractures, and injecting cold water underground through injection wells; the cold water flows into rock fractures and is heated by the underground high-temperature rock, converting into high-temperature hot water or steam; the high-temperature medium is then transported to the surface through extraction wells, and subsequently drives the generator unit through heat exchange equipment to complete power generation. Geothermal energy is clean and renewable, and the entire extraction process has no fossil fuel combustion emissions, making it a new energy source with great development potential.
