A DIY windmill can provide you with free energy anywhere you might be and is ideal for an off-grid location. The following 23 DIY ideas will show you how to make a windmill that can produce large or small amounts of energy to meet whatever energy needs you have.
DIY windmills are very simple to construct and if you can turn a wrench and operate a drill, then you have enough skills to build a homemade windmill. A windmill generator harness the power of the wind to create electrical power and depending on the size of the windmill can supply part or all of the energy you need.
Check out these 23 DIY windmill ideas we have found for you and discover how you can save money and have all the electrical energy you need without having to spend a lot of money.
1- DIY Windmill Redo
Windmills are exposed to all the weather elements year-round and sometimes they need a redo to keep them in good working order. This YouTube video will show you an easy and cheap DIY windmill redo to keep your windmill turning smoothly.
Whether your windmill is decorative or functional, it will need a little maintenance every few years. Might as well give it a face lift with some new sails and a coat of paint while you’re at it.
To make this diy windmill on youtube, use leftover parts, like metal duct work, metal rods and PVC pipe to update the diy windmill and the redo will cost you almost nothing. DIY windmills are constructed with minimal parts, so saving leftovers from other DIY projects will soon add up to enough components to redo and update an old windmill.
Reusing, recycling, repurposing, and redoing are at the heart of most DIY projects. It’s all about creating what you need with what you have to save money and be kind to our planet.
2- Wind Turbine
The second one we are going to discuss is a great project for a school science fair and it’s cheap to build. Watch this YouTube video to discover how to build your own wind turbine using PVC pipe.
To make this diy windmill project like this one on Youtube just take small sections of PVC pipe, cut in half and attached to the ends of the blades to catch the wind. As the sails begin to turn, they will increase in speed and generate electricity. Very simple principle and an easy DIY project that can be increased in size for use on an off-grid homestead.
Anywhere you need to generate free electricity, this powerful PVC wind turbine can do it.
3- Deck Sized Windmill
Here we have a stylish wooden windmill by Instructables that is small enough to fit on your back deck. It adds decor and keeps the air circulating while you enjoy sitting outdoors.
