Hydroelectric Generator

At a glance..

For making small amounts of electricity without building a dam, the small-scale hydroelectric generator is often the best solution, especially where fast-flowing streams on steep slopes are close by. In this activity, you will use plastic spoons to build a model of a simple micro-hydro system. It generates surprising amounts of electricity, provided you have a supply of pressurized water, such as from a lab sink. This model closely resembles real micro-hydro designs, and can produce enough electricity to light a small light bulb.

The details..

Micro-hydro Basics is an instructional guide for anyone interested in generating their own electricity using a small-scale hydroelectric generator. The book explains the basics of how mechanical energy from falling water can be used to spin a turbine and produce electricity. Unlike large dams that require deep reservoirs, this book focuses on low-impact solutions that are appropriate for ecologically sensitive areas or rural communities where fast-flowing streams are nearby.

The book includes detailed instructions on building your own micro-hydro system using simple materials like plastic spoons and corks. Readers will learn about the principles of electromagnetism and electrical generators as they construct their own alternator using magnets and coils of wire. With pressurized water from a lab sink or other source, readers can create enough electricity to power small appliances or light bulbs.

In addition to providing practical guidance on constructing a working model, Micro-hydro Basics also discusses larger scale applications of hydropower technology around the world. Many countries rely heavily on large-scale hydro developments for their electricity needs but smaller systems have great potential in remote locations without access to traditional power grids.

Overall, Micro-Hydro Basics offers accessible information about renewable energy sources while encouraging readers to take action towards self-sufficiency through hands-on learning.
