  • The design had me convinced until you put in on a crank shaft....

  • put a mini one in a box and use earth energy and heat from sun to power small h2o pump to create standing wave mini pool and perpetually drive this device. who needs power companies

  • The simple solution to this, is to remove the crankshaft, and use a hydraulic piston that drives a generator. That way, you can just make a very long piston, and make sure it doesn't bottom out.

    Kinda like the Wave Star project does.

    watch?v=Fu5AK_a9KN0

    They intend to make a power 500KWH station, that should be quite a sight. :)

  • I love seeing designs like this,the only problem I really have is with one unit no one ever talks about what the projected power output is on one of these units.farming waves is a great idea and frees up land mass for building and farm lands.A vertical tower of these under water would be just as great as if they did more vertical farming here on land aka fish farming /agricultural.look up farm raised abalone,really interesting just needs to be scaled up vertically for more production.

  • your back to front on this matter, anchor the piston to the sea bed, and have the floating buoyant end move, the way you have it is classroom, but at sea if you know the sea, you wont find it quite so forgiving guys, and your 3 anchors points will REQ continual adjustment for tidal and wave ext reams, when you need only 1.

  • and amazingly you can power 3 toaster ovens with the energy produced by this unit. :)

  • maintenance. again, too mechanical. what happens when barnacles, sea snails, seaweed and all kinds of slime grow on it and gum up the works? Some kind of bladder system must work better. Feed the compressed stream of air/water to remote generators.

  • See nodding ducks.

  • anyone looking into green energy should vist The Zeitgeist Movement or the Venus project. Some problems to overcome before green energy is taken seriously

  • it is an awesome technique and a simple phenomenon to generate electricity from waves

  • tnx dude

    was very usefull for my project

    

  • I like this type of energy resources and in my opinion he's much more serious than wind turbines, no free country in which to live, are produced in 50% of the total energy directly to the water

  • waste of energy, less will be generated when the tide moves less that the max, and there is energy loss when the waves are higher than the range of motion of the piston.

  • How come you don't advertise this video? It's cool to make a video, but NOT to advertise this video to people who can make these machines, thus creating jobs for you and your friends is just WRONG! ADVERTISE THIS VIDEO!

  • Wave timing change simultaneously. 

  • What if the wave timing doesn't match the correct position of the crankshaft?

  • this is cool

  • Use a floatation device connected to an arm, which drives a fixed ratchet system, like a bicycle rear wheel drive, then it will adapt to different wave sizes

  • This works on only one size wave. Fine for a wave tank, but real waves come in many sizes.

  • @PlayT0E

    not if you can change the height of the machine to suit the waves

  • instead of using a crank shaft in the top center, perhaps there is a way to capture energy through any movement of the buoyant piston?

    I'm no engineer, but for example if there were a way to harness movement/kinetic energy at multiple points along the inside of the shaft. These multiple points would be activated by any movement and harness more energy with larger waves and no need to redesign/recalibrate for regional wave heights

    If this kills fish it will never "float" lol (sorry bad pun)

  • @Cradle2Venus Search Youtube for "Pelamis project". Actually, it's the best way to obtain electrical energy from wave energy, independently of wavesize.

  • Yes, this is "tuned" for only one wave size. Real-world conditions have partial waves on top of bigger waves, so that the crank-shaft will be reversing direction of its spin all the time. HOWEVER, maybe this isn't a problem, the generator should generate electricity regardless of its direction of spin. There are significant energy losses (lost angular momentum of the rotation shaft & generator)

  • Sorry, but this only works for one wave-hight; any wave smaller will not complete a turn of the crankshaft, any wave bigger will interrump the motion at the top of the turning cicle till the wave had passed, besides doing heavy force on the crankshaft.

    Anybody had noticed that?

  • No, because it is a floating devise, so it sits on top of the water level.

  • Yes, untill it reaches the top of the crankshaft turn, then water have to pass over the float

  • In which case the whole device will rise.

    Anyway, sea level does not change that much, in a hundred years, maybe.

  • The whole device won't rise if anchored, but there's a top point in the crankshaft turn, if there aren't waves big enough the crankshaft won't turn completely, if the wave is bigger the turning will momentanly stop. That happens in every wave; ignoring tides, etc...

    If you not understand yet, just build one of those with household materials and you will see clearly the many problems

  • The rotating of the crankshaft is only a dramatic demonstration of the capture of the mechanical energy. We have progressed far beyond. One side linear movement of a lever which can capture any height of the wave and fluctuating wave heights have been developed and this linear motion is converted into one sided rotary motion using mechanics.

  • Can you give more details? This is very intriguing.

  • if it sits on top of the water the float will just move with the rest of the device and the crank wont turn.

  • totaly... good try though...

  • At the equater you got same size waves. But if you go north or south the waves are changing attitute.

  • yep

  • @vipondiu YES, I noticed that as well. the machine is stationary, and the sea level rises and falls. There's a design that is floated on the surface, so no matter, high seas, or calm, the wave action always actuates a unidirectional cam that powers and collects energy.

  • @vipondiu

    Man, it seems that, thinking a littke more this can be solved easily. Watch the video z5QnufvctV0 her in you tube, You'll see that's already a reality

  • @ttoomuch Yes, buoy type generators are not new, but they use pneumatics or hydraulics, not a crackshaft. My point was (more than 12 months ago) with the crackshaft

  • india have a look at how clean the water is there then go on about what ever ya like

  • Sa-mi bag .. in natia voastra ce-a mai spurcata di lume !!! fucking devils .. all the world knows who you really are ! you believe in devils .. elefants, snakes .. etc .. fco

    Do to the rest of the world a favour, just stay there, don't spread your infection elsewhere ...

  • Instead of the crank shaft and the gear box why not just have a magnet in the tube and have the tube be covered with copper coils so the electricity could be generated directly by the alternating motion of the current than the all the energy loss due to energy transfer with the crankshaft and gearbox? But this is by far a very innovative way of harnessing wave power though .. nice work ;)

  • Not Cost Effective !

  • i guest many white people are jealous by this idea hehheee

  • LOOOLLL I'm a white boy and I didn't have so much fun & laugh since months .. This "imvention" can come only from brown pipal ... LOOOLLL GOOD WORK ! I wait for more please. INDIA RULES ....

  • LLLooooooLLLL

    India rules, as always, cutting edge technology. Just can't stop laughin'. Keep trying guys ...

  • Someone needs to take a trip to Mumbai.

  • what a horrible thing to say ! NO ONE deserves a trip to Mumbai !

  • build it then you moron.... ya would not make comments like that if you could actually afford to build it

  • what if the crankshaft doesnt make it all the way over/under or get stuck over/under?

  • The rotary crankshaft is just to demonstrate the working principle. We have progressed far beyond that. We can use one side irregular up and down stroke based on uneven wave movement and convert to rotary motion using mechanics.

  • My project uses old platforms as base for many generators but it can be on land too. It uses old technology and nothing that does not suppose to be close to the water is in the water. Take a look on my video: ocean power, wave power, wind turbines, sun power, (ocean power, the blue power (3rd edition))

  • ideal example of oscillating water column i know since i m doing this as project in renewable energy resource as a third year mechanical eng project

  • All you nay sayers are no different than "The World Is Flat" idiots of the past. Wave energy has been successfully harnessed for commercial usage in the US and Foreign countries. There are many different designs that work. The main issue is design strength to last for decades and self regulation regardless of small or large waves. Destroying precious resources and polluting the air will go soon.

  • Thank you for the support. A design cannot be perfected in the first shot. An innovator always pushes ahead inspite of faults. Progressively all the defects will be overcome and we would have a design that would deliver. I am thankful for both the positive and negative criticisms and have made suitable modifications in the future designs.

  • Waste of good graphics on a ridiculous idea. Stick to what you're good at.

  • I don't see why it's a ridiculous idea. It's an animation of a white board concept. Yeah, it's not necessarily going to work for every situation in the ocean, but there are plenty of devices in place that are specialized.

  • that's well and good but how do you intend to keep the amplitude of the wave even with the piston full stroke? or how do you keep the device at the rest position of the waves?

  • @DonHoraldo hydraulics instead

  • nice graphics :D

  • like the chains are going to keep the surrounding unit stable as shown in this video...what crap...the surrounding unit or housing would need to be anchored by a rigid body, not a chain for this to work.. the turning mechanism at the top is ridiculous as well..any pause at top dead center or bottom dead center would cause problems.. FAIL rethink the entire process!

    FAIL. F

  • If these pistons can drive a lot of smoothly one side rotating wheels as momentum, very nice indeed. Share this to the world, so we help each other instead of destroying each other. We love Youtube because it is simply language.

  • Looks very good but the design can still be optimized to completely avoid any interaction between moving parts before gearbox.

  • not practical, the wave is to stable to turn the piston

  • i am doing this for a school prodject but how are u going to get the electricily to land that way???

  • This design is similar to the parabolic OWC installed by energetech off the shore of Wollongong, Australia. Its also like Aeqir Dynamo, and like Denmarks wave dragon. The simplicity of this design is an advantage. mooring to the sea bed presents serious limits. the massive forces involved with freak waves and storm conditions could gobble up this type design.

  • Mooring of the device is complex but possible.Ocean bottom submerged concrete piles with high capacity stay wires could do the job. Also the side walls could be designed to close and the device shut down just before an approacing storm. the side walls height is designed just for the device and extra height waves could sail over the walls.

  • wave is usually oscillating with various amplitudes and frequencies. piston and crank are fix relatively??

  • The animation is only a indication of the method. Instead of having a fully rotating crank you can also have a single side crank movement to take on varying amplitudes and frequency.We have developed a mechanical device to convert single upside and downside movement into one direction rotary movement.

  • consider using a fluid power cylinder as a dampener for wave properties . If the amplitude rises beyond upper limit then cylinder retracts creating fluid pressure to then be stored in an accumulator for use as energy. in concept the cylinder functions much as a shock absorber, sort of like the active suspension on a car. these systems are well established for automotive applications. designing a system to do the job and survive harsh ocean conditions is likely the big challenge.

  • we are not planning to tap wave power from freak waves above the design limit. The higher waves will pour out the water from the top side of the device.The more the complication the higher is the cost of installation and maintenance.

  • tapping power from a tidal wave is not the issue, surviving the storm is. the ocean has a definite way of destroying man made things.

  • bridges on the sea, wind mills on the sea are all man made. The design should calculate the extreme loads and provide for it.The equipment is simple and economical and payback period is fast. Higher risks can be taken

  • ok, fair enough. best wishes in your dealings.

  • tapping energy from a tidal wave is not the concern, but rather, surviving the storm should be a top priority in your design. storms on the sea have a way of destroying man made things.

  • now.....everyone is an expert....i am referring to all those who comment...lol

  • smart design

  • What is the wave rises more than usual ? Then it would temporarily jam the lever in the 'up' position and the whole thing would stall, wouldn't it?

  • He is doing it wrong.

    It should be upside down.

    More strenght. Better control for tides

    etc...

  • It should be underwater have the water pull it up. More control for tides wave size and more strenght

  • bevel the face also for more suface area, two systems palced in accordance with wave lenght complimenting eachother

  • if you really want to get fancy there are hundreds of thing you can do to increase strenght. One thing would be an air trap so that when the upper sysem falls it pushes air into a lower pressure area on the rising system adding lift to that system. this air would be released when the rising system starts it descent.Also by using pressue area you can alter densities of rising and falling systems.
