摘要

近年來，全世界出現各式各樣接連不斷的怪異天災，似乎是地球在向人類發出最後通牒，企圖讓人類了解現今能源已經被過度濫用，受污染的環境已造成異常的氣候，現今，如何節省能源與增加再生能源的使用率，是人類所該認真思考的一大議題。目前所被關注的再生能源技術大多都集中在太陽能、風力能、水力能、生質能、地熱能、海洋能及地面機械綠能等，其中，地面機械綠能在近幾年才開始逐漸被重視。這裡所指的地面機械綠能是由施予地面的正向力所造成，當行人或車輛行走於路面時，都會對路面施予正向力，此種能源大多以脈衝形式存在，當能源的狀態以脈衝形態出現時，就會變得非常難以利用，雖然如此，因為地面機械綠能累積起來十分龐大，許多技術紛紛加入開發行列。隨著科技進步，用來採集脈衝能的技術已有壓電效應、電磁感應、靜電容改變、脈衝轉成渦輪旋轉及熱／聲發電技術等，本研究在探討地面機械綠能回收技術，透過初步概算來了解地面機械綠能究竟有多龐大而如此值得被開發。

Recently, a variety of natural disasters appear world widely, which seems to give human an ultimatum and show the result of overused earth energy. The polluted environment has caused the exceptional climate. Today, how to save energy and how to increase the use ratio of renewable energy are the serious topics. The currently focused technologies of renewable energy are for solar energy, wind energy, hydraulic energy, biomass energy, geothermal energy, ocean energy, ground mechanical green energy, etc., where the ground mechanical green energy is developed in the recent years. The so-called ground mechanical green energy here is caused by the normal forces which are supported by walking people and running vehicles. In general, the ground mechanical green energy is the pulse energy which is difficult to be used. Even so, the summed ground mechanical green energy is extremely large and many technologies are therefore developed for harvesting. For example, piezoelectric effect, electromagnetic induction, varying capacitance, pulse to rotation, heat/sound electricity generation technologies, and so on. This study is focused on the ground mechanical green energy harvesting. Using preliminary study to estimate the energy and show its value in this work.
