Homemade hydroelectric power station from an old washing machine

I have always been fascinated by obtaining free energy from natural resources. And somehow I got the idea to make a simple mini power station that would generate electricity from a passing water stream.
Homemade hydroelectric power station from an old washing machine

It all started with an idea to use the drum of an old washing machine as a water wheel - a miniature homemade hydroelectric power station.

Straight blades made of moisture-resistant plywood were attached to the drum using metal corners.

The torque from the water wheel is transmitted by a belt to a bicycle dynamo (direct current generator). The generated electricity is supplied to Light-emitting diode. All you have to do is turn the wheel slightly by hand and Light-emitting diode will start flashing.

The basis of the entire structure is a bicycle frame.

Two bearings allow the water wheel to spin freely.

The first tests on a small river showed that the water wheel on the frame was installed too high, which did not allow the flow of water to spin it normally.
After minor changes in the frame design, the wheel began to be positioned lower and the rotation speed increased sharply.As a result, the dynamo began to rotate and Light-emitting diode at 4.5 V it lit up.

This is how a homemade hydroelectric power station was created from old trash.
Next, the mini hydroelectric power station assembly was installed on a small stream.

It produces only a few volts, but it is enough to glow LED.

It was a good experiment to start with.

Further improvements in the project


Further improvements to the water wheel should affect:
  • Build a mini-dam to increase water pressure. At the same time, there are no plans to completely block the river so that the fish can escape in the second stream.
  • Install a pipe under the dam through which water will flow to a homemade turbine. Place a casing in the pipe using a rubber conveyor belt. By blocking the flow of water through the pipe, you can carry out maintenance of the mechanisms.
  • According to calculations, the turbine will produce approximately twice the power of a water wheel. In addition, replacing the water wheel with a turbine should eliminate the problem of freezing in winter.
  • The flow of water will spin the turbine, transmitting torque to the generator. The turbine will be supported on two bearings made of solid wood. With regular lubrication they will last a long time. The thrust washer will keep the mechanism from moving laterally.
  • Make metal blades, calculating the angle at which they need to be bent (the power of the hydroelectric power station depends on this parameter). The blades will need to be screwed on using rubber gaskets to avoid tearing them off.
  • To transmit torque, use a shaft assembled from pipes.
  • Install the generator.Place a pulley on the generator that is smaller than the one installed on the shaft. This will increase the speed, which is necessary for the generator to operate efficiently.

The generator should produce about 600 W of electricity. This will make it possible to connect household appliances. If the next stage of the experiment is successful, it will be possible to think about further modernization in order to generate several kilowatts of electricity.

    Damn, make so much crap to light up Light-emitting diode... The author really burns!

      I agree. I read the title, I think it’s cool. And this...

    Well, you shouldn’t, the main thing is to start and do it.

    Blow on the diode and it will burn, let him do the experiment with one hand on the leg of the diode and the other leg in the network and it will burn.

    Author, go ahead and don’t listen to anyone. What you are doing is really interesting, keep it up!

    )))) We need to sell the technology to the Saudis. And let them light up LEDs as much as they want. On all its rivers.

    Why reinvent the wheel if it has already been invented?!

    Gorenje washing machine in front. Behind Zanussi. And the tank is actually from Hansa. Why couldn't you choose a tank?

      but he can proudly say that several large companies worked on this project

    Is it okay that the bicycle generator produces a change? Does the diode work from constant voltage? Is something not growing together?

    At one time, a mini hydroelectric power station was made from car parts. Wheel-reducer-generator 14V battery wiring further consumers radio bulbs 12V etc.
    Low charging was compensated by a battery that was charged at night
