I made this project with a person I met in a science internship at the Foundation For Diffusion of Scientific Knowledge. (Saad Ahmed)

This design is similar to that of US patent 7355298. It's not for profit. I've changed almost half of the equipment used. And the design.
A siphon refers to an inverted U-tube that allows liquid to flow uphill above the surface of the reservoir(a tank with the greater height of water) without the help of pumps, powered by the fall of the liquid as it flows down the tube under the pull of gravity, and is discharged at a level lower than the surface of the reservoir.
So in this Instructable, I'll be demonstrating the concepts behind Siphon Generation. And how to build your own Siphon Wave Generator at home using easily available hardware materials such as pipes.
Waves are a powerful source of solar power. The sun heats the earth causing the air near the ground to heat and rise creating wind. The air over the sea is cooler and therefore falls. This change in wind, causes wind to blow from land to sea. When the wind blows over a body of water the energy of the wind is exchanged to the waves it creates. The power of the waves is concentrated solar power. The power created in the waves is both the movement of the waves and the lifting of the water to the crest of the waves. And therefore these waves can be used to generate huge amounts of energy.
Wave power plants extract the energy from the waves and convert this energy into useful electric power.
The main advantages of extracting energy from waves are:
- The energy is solar with no pollution.
- Wave power is renewable and is a source of power great enough to power the world.
- Most are costly to build in relation to the amount of electricity extracted.
- Most generating devices are complex with numerous moving parts that experience great wear due to the salt and sand in the ocean often causing the cost of repair to exceed the value of the electricity extracted.
- Storms often destroy entire wave generating stations.
Step 1: Siphon Generation: the Concept
- Hydro Static Pressure
- Atmospheric Pressure
- Pull of Gravity
When the crest of a wave is at the first vertical intake pipe the water level will be higher at that pipe than any other vertical intake pipe, thus the water will start flowing up the first vertical pipe at the crest of the wave. The one way valves in the other intake pipes would prevent the water from flowing out thus forcing the water to flow through the horizontal generating pipe turning the prop and generator, thus producing electricity. The water would then flow down any of the exhaust pipes in which the water height outside the exhaust pipe is below the height of the water outside the first intake pipe due to the siphon effect.
When the crest of the wave moves to the second intake pipe the water level is higher at the this pipe than any other intake pipe causing the water to flow up this pipe through the horizontal pipe turning the generator in the same direction, generating electricity and flowing down the exhaust pipe closest to the trough of the wave due to the siphon effect.
The valves in the intake and exhaust pipes would jointly cause the water to flow in only one direction through the horizontal pipe, from the intake side to the exhaust side. This would cause the generator to turn in only one direction.
After you pour a little water into each bucket you then get the air out of the tubing priming the system. Then, when you pour more water into one bucket it'll siphon over to the other bucket, spinning the turbine, until the levels equalize. Then you've got to pour more water into one bucket to get the siphon action started again. Once both buckets are filled up you've got to get rid of enough water to make more room in the buckets.
Step 2: Materials Needed
- 12 ft of 11/4" Pipe
- 3 ft of 3/4" Pipe
- 4, 3/4 " Check Valves
- 4, 11/4" Elbow Fittings
- 4, 11/4" Extended-T Fittings
- 4, 11/4" to 3/4" Reducers
- 8, 3/4" Screw Pipe Fittings
- Pipe Glue
- A Small Fan
- Soldering Iron Or Drill Bit
- Pipe Cutter
- Suction Pump (Optional)
Step 3: Cutting the Pipes
- 4, 10 Inch Pipes
- 4, 6 Inch Pipes
- 2, 4 Inch Pipes
- 8, 4 Inch Pipes
Step 4: Gluing Step 1
Step 5: Gluing Step 2
Do this twice.
Step 6: Gluing Step 3
Step 7: Drilling Holes
Step 8: Screw in Valve
Step 9: Assembling the Legs
You need a total of 4 legs. With two legs showing the check valve arrow in the downward direction and two in the upward direction.
Step 10: Assembling the Final Unit
Step 11: The Motor
Place the motor into the hole we left uncovered in the beginning. Super glue it inside in such a way that the fan can spin freely.
Connect the leads of a multi meter to the nodes of the waterproof motor inside and seal the end, allowing only the leads to stick out. (I didn't do that properly here).
Step 12: You're Ready!
All the air must be removed from the pipe by any means including but not limited to: flipping the unit upside down, opening a service valve in the top pipe and lowering the unit completely under water until all the air is removed then closing the service valve and raising the unit, or preferably by using a service valve located at the top of the unit that can be attached to a pump to pump all the air out of the unit thus filling the unit completely with water.
