Energy: Geothermal Energy

地熱能是由地殼抽取出的天然熱能,這種能量來自於地球內部的熔岩,並以熱力形式存在,是引致
Geothermal energy is nature from Earth's lava can cause earthquake and volcanic eruption.

火山爆發及地震的能量.透過地下水的流動和熔岩湧至離地面1至5公哩的地殼,熱力得以被轉送
The heat can transfer near to the surface of the earth by deep 1~5miles groundwater.

至較接近地面的地方.高溫的地熱能源可以用來發電.熱水或蒸汽從地熱提取出來,並用於推動渦
A very high temperture and pressure steam makes the blade of generator roll,then produce electricit.

輪發電機發電.

地熱能大約轉換過程:熱能->動能->機械能->磁能->電能
The energy transformation process:heat->Kinetic->mechanical->magnetic->electricity.
