水可以發電家庭自來水水管如何設置可以發電？

我國自來水壓力規定最高不超過0.35MPa，一般供水壓力0.07MPa，取0.07MPa。

水中某一深度的壓強為P=ρHg，簡略計算約為7.1米水柱高。

水力發電能量轉換效率一般75%，1立方米水發電1000kg x 9.8m/s x 7.1=0.0193千瓦時

呵呵。

有沒有想過：自來水的壓力是哪裡來的？

所有人都這干，自來水公司供水「壓力」好大。

已經有人這麼做了。還分析了能量的潛力呢。

Abstract: The purpose of this paper is to bridge the gap between the awareness of potential for energy recovery within Municipal Water Distribution Systems and the lack of knowledge of the extent and location of such potential so as to increase the sustainability and resilience of South African cities. This is done by leveraging asset management data, contained within municipal infrastructure asset registers and asset management plans, to identify energy recovery and leakage reduction potential. Data from asset registers and customer profiling within the municipal asset management plans were used to develop a hydraulic model for a municipal water distribution system. The customer service charter within the asset management plans describes the level of service, which was used in evaluating minimum operating pressures within the system. Comparing this to a pressure profile from the hydraulic analysis of the model, identifies excess pressure areas, exploitable for energy recovery. The novelty of this research is the exploitation of asset management data from Infrastructure Asset Management Plans and Asset Registers for the development of a hydraulic model to analyse energy recovery and leakage potential within a municipal water distribution system. Asset management data were used to identify an average annual preliminary energy recovery potential within the Polokwane Central District Metered Area of 2.3?GW?h, resulting in an average annual leakage reduction potential between 3.3% and 4.2% of potable water, adding to the asset management value chain.

有一種裝水龍頭上的燈就是靠自來水發電，淘寶有

本來想說這個問題點進來就輸了，然而還想說一下。

自來水發電還是有一些小的使用場景，比如將所發微弱的電用於探測水的溫度。其他的用途，應該得不償失，也沒有特別的意義。
