our observation:
在不少新聞中可見,人們浪費電源的情況越來越普遍,除了浪費地球的資源,更會浪費更多金錢。
根據一項水務署的統計,香港2023年總用水量多於10億立方米。
我們發現香港人的用水量持續增加,而這些水最終被排出大海前,就應該好好運用!
Project’s objective
這件產品的主旨:我們運用了香港高樓大廈的特點——污水會由高處流到地下,水的衝力很大。所以我們便想到可以用淋浴完的水流力,轉化為可用電能。這樣就可以減少對化石燃料的倚賴。
這件產品帶來的好處:
這項可以運用洗澡完的水源再次用來發電,二次使用,以節省電費。
該設計利用了水力發電的原理。廢水倒入水箱,水流經管道,利用馬達驅動葉片旋轉,為建築物的各個部分提供動力。
這是一個運用了再生能源的水力發電燈,因為我們使用了每個住戶浴室洗澡的渠道然後運用水流發電,供應大廈的照明系統。
SDG goals &The principal behind this project
這水力發電燈符合了聯合國可持續發展目標中第7項—經濟適用的清潔能源。

Experiment
1)Build the turbines
2)test if they work
3)test each turbine with the different water amount and hose sizes
4) compare to see which light bulb will generate the most voltage
Objective:to test which turbine generates the most electricity
TEST
目標:測試哪台渦輪機發電量最高
1)組裝渦輪機
2)測試渦輪機是否運作
3)使用不同的水量和軟管尺寸測試每個渦輪機
4)比較哪一個燈泡產生的電壓最高

End decision: no pipe
Final decision
Our challenges meanwhile making the project and the solutions
1.We found that the water force was not enough for the engine to run power.
2.We found that the pipe might not be big/wide enough.
We will do a experiment of different motor and choose the motor with strongest power after testing.
We will try to use a pipe which is more broad and wide . Also trying to make the water force stronger.
Problems:
Soloutions:
1.我們發現水力不足以使引擎運轉產生動力。
我們將對不同的馬達進行實驗,並在測試後選擇功率最強的馬達。
2.我們發現管道可能不夠大/不夠寬。
我們將嘗試使用更粗更寬的管道,並努力增強水流壓力。
3.After two weeks of testing our prototype which contained wood, it had mold on it and we couldn’t continue using it.
We used another broken turbine to combine with the usable parts of the one with mold to create a new turbine.
Our challenges meanwhile making the project and the solutions
3.經過兩週的測試,我們的原型(包含木材)上出現了黴菌,我們無法繼續使用它。
我們將利用另一台損壞的渦輪機,與帶有模具的渦輪機的可用部件組合起來,製造一台新的渦輪機。
