- (Visit: www.uctv.tv/) Ocean waves and tidal currents are one of the most untapped and important, clean, cheap, rich, and reliable sources of renewable energy on the earth. UC Berkeley professor Reza Alam and his team at the TAF Lab (Theoretical & Applied Fluid Dynamics Laboratory) have developed a "wave carpet" which can extract the energy of ocean waves and turn it into electricity and freshwater for households and cities.

This is absolutely flawless in genius and ingenuity! Outstanding to say the least! I, for one, im personally amazed.
I have been working as an engineer for 45 years and taken a profound interest in renewables for the last 10 - 15 years. In my humble opinion this idea may seem elegant but it will require huge amounts of maintenance. No pilot wave project so far has had any success. The oceans and great lakes are unforgiving places, unfortunately.
o.o' are you fucking kidding me??? many wave projects have shown more then marginal success like the oscillating water column, the tidal current turbine, the salter's duck, the point absorber buoy's and the wave energy attenuators
I agree on the maintenance. Lots of debris, plant growth, shellfish crawling underneath, various flora/fauna living on top of the carpet... I can see the success, but over time, over 5 years? over 10 years? over 40 years?
Great concept. Cylinders in an ocean environment is a rough go. You are building them to fit your tank? Find a trampoline and replace the springs with your choice of energy absorption device. Make sure you talk to some crab fishermen about what happens to their pots during storms. They have lots of first hand knowledge about the sea bed and materials and shapes that hold up. From what I've seen you have a major piece to making this work with the flexing carpet. How you get the energy from that is the part that needs more input. Keeping it simple is a great way to getting a viable system
Cool! Wave energy collectors I've seen before all involved some sort of flotation, vulnerable to wind, storm crests and traffic. These 'carpets' seem a lot more promising.

Wave power has even been used to power boats and sea going research drones. Issues include how big does the wave need to be to get any power and what happens when you have a storm.
It's an interesting idea, but in my option needs a lot of infrastructure, hydraulic lines anchoring the mat etc. I prefer the tethered vertical cylinder with an attached float that moves with the waves.
I’m very skeptical about any sub sea surface energy generation technology. Salt water is corrosive and maintenance is likely to be expensive. The energy density of this system sounds promising, but it is not as if we have a shortage of space for solar or wind. Would be great if they can implement this in a cost effective manner, but I doubt it
Great design and experiment!
Can someone explain what the status is of this technology? Has it been tested under practical circumstances or applied somewhere? Thanks!
same question!! what happened to the design?
nice work. i am working on one such project by which we can convert the gravitational energy in to electrical energy. so we need to run behind the sources of power like rivers, oceans, sun and other geographical locations. looking forward to have some collaboration in this project.
Shalom Greetings! Congratulations in advanced on great work. I’m sending peace love and light from Las Vegas!
Keep up the great progress👍
This is a good idea but their is always environmental issues and also animal issues in which they can interfere and get in the way of the energy converters. If your going to do something like this put it in a secluded area where nothing can get in the way.
I tried to contact Marcus from this video for more information or details. However I haven't got any update.
My humble request to research scientists is expedite this research and in my opinion this is very promising.
Hope ***** you also agree with me.
An interesting take on an old idea.
How much of the wave's energy would be "removed" for each liner meter of carpet? I'm thinking that something like this would also be useful for attenuating waves near vulnerable installations, harbours etc.
***** If you watch the video they tell you that one square meter will create enough power for two households. That is great. You could use it on houseboats.

I watched the video. The problem is that "Power per square meter" is not particularly useful as a metric for wave energy. Wave fronts are linear. An effective wave energy converter will lie parallel to the wave front, and remove most of the energy in a small distance. If there is a lot of downstream energy, enough to install a multitude of pistons, it means the first one isn't doing its job. You should see a significant reduction in wave height after the device. That means it is removing energy from the wave and converting it to electricity/pressure/some other form of energy.
Also, there is a large range of energy use for households, anywhere from perhaps 10kWh per day to 100kWh, depending on the size of the household, heating and cooling requirements, energy efficiency, etc etc. Within this large range of variables, it makes more sense to quote a specific energy output from the device, in commonly recognised units.
Furthermore, the energy output is directly related to the energy profile of the wave conditions on site. Without knowing what the energy input is for any particular output, we cannot calculate the efficiency of the device.
It is often more useful to simply state a percentage of energy conversion efficiency, along with the price per kWh if the device is operating within its design envelope, the so-called LCOE.
Hundreds of different wave power devices have been proposed. Not one has yet shown that it can deliver reliable power at a price that makes it competitive with wind or solar. I hope this changes soon....
great design.. if only there are tidal power company here I would love to switch on using this electricity.. its more cleaner... and green...
Tidal power is different from wave power. Tidal power usually involves implementation in tidal estuaries and comes with environmental concerns such as interfering with sea life access to the estuary, turbines harming sea life, noise pollution, and increased sediment build up. It is also pretty expensive, so personally I can’t see the point of it.
I want one for my beach Surfline - no more utility electricity bills.
The Trouble with Tesla Roof Top Solar Tiles is you gotta get a ladder
to get a new solar roof put up
??? Yeah, ladders are too much trouble.
Insted of these hydrocylinders it is possible to lay an inflateble mattress to the bottom and to use it as a diaphragm-type air compressor.~~~~~
The inflatable mattress should be multichamber (as accordions array)~~~~~
Awesome idea. Fewer moving parts is always better. What if use piezo carpet instead?
I have seen that concept before, like literally 40 years ago, and they had it at the surface, but mounted on a long rigid beam. It seemed like it would work
@@someotherdude That can lay a wave-power carpet along a sandy beach who will master technology of profitable manufacturing and repair of an inflatable carpet
***** , This looks so promising technology, it might be way ahead of nuclear technologies.
cool thing need to be develop in other countries also
If this wave energy is converted to electricity, in case a tsunami is created after an earthquake near the California coast, would that cause an explosion at the electrical grid station? Or would it simply destroy the undersea carpet & the equipment first before the enormous power could travel to the electricity generating station?
Overload& Breakers & what you said-damage & float away, put some GPS in them to satellite track movement if lost & for tracking wave power, frequency etc when working.
BlessAll2015KC It's an unworkable system. Dumb ideas out of the best schools.
So cool!!

Earth Follows Wave
Wave Follows Earth
Moon Effects Wave
Wave Effects Moon
Is that right?
Yes the TIDE lose energy to friction this energy COME FROM THE MOON
So but the moon is huge and going fast enough to escape its orbit so it wont slow much any time soon
And will likly escape before that
where is it now?
Such places as the Pentland Firth and the mouth of the Bay of Fundy are the most violent places in the oceans. Waves are also violent. There is a better way to utilise the power of the tides. I have two such designed, but have no idea how to go about capitalising them. The professor guys and the guys with the money would laugh at something so simple and I could not imagine the chairman or manager of a big corporation taking an old fishing skipper seriously. G,D.

I`d be interested in your ideas as i have many of my own, plain & simple devices but like you commercialising them with nothing in your pockets is impossible.
how about the sediment transport? the carpet would not be covered by sediment or?
update !!! 2016 ? Hello 2019 now !!!
Hello nearly end 2020 now !!!! I don't see any wave forms of renewable energy anywhere that is commercial .................
Hi, I am working on final year project named Oyster Wave Energy Converter. I need help regarding my project. How to make this project with low cost which can produce Upto 20W power.
I'm a bit late you still need help
any update 2020?
Is there an update on the 2016 ocean test?
Sounds a lot better than
Simpson's NukePlant
can magnetic energy influence be applied?
Magnetic energy....
Be specific
rain and snow is for renewable energie.
Don't you want this near the surface? I like this idea though.
Fixing it under water?
What s the update on this project
Nice engineering .....hope the world rely on renewable sources other than fossil fuels ...
Adevarate copilarii.
Why full moon day effective more energy in waves
Invest in this not fossil fuels
Too many moving parts... Oceans will eat up these units. Spindrift has a better alternative. IMO
According to the studies there is no impact on the ecosystem and they would be placed in dead zones.
Conservatively speaking, how much energy can you harness per hour? If we all try conserve power with conservative appliances and conservative cars, we may be able to run our homes without outside power.
Maybe now they can pump the ocean water at desalination plants with this

Who's going to keep vacuuming up all the sand out of the carpet? Sand in a carpet is a bitch.
interesting
How do I get a job in this industry?! I hate web development!
Lol, maybe in ten years you'll get to where I am on it. Try combining this concept with ocean thermal engineering, and air conditioners. It's complicated, but if anyone cares to hear, I'll explain it.
Explain
@@pencilpaper771 Ok, so here in California a big chunk of our power goes to cooling houses and businesses. So I figured turning the big negative energy draw into a positive was the best place to start. air conditioners don't destroy heat energy, they just relocate it. So instead of using a compressor on site, you absorb the heat by physical state change of a refrigerant. Pretty much a simple evaporator with a valve controlled by a thermostat and a capillary tube in-between them. The evaporating refrigerant creates pressure. Which part of it's energy is used to turn a Tesla turbine. Which spins a fan that brings the heat of the rooms air to the evaporator.
@@pencilpaper771 Then the vapor makes a long trip to the ocean. Using ocean swell pumps it is compressed and the heat is given back off. Run that hot fluid through a heat exchanger and you get cool refrigerant once again and hot ocean water. Then, using vacuum distillation, separate the water from the salt. Also, anywhere in the lines of moving fluid or vapor, turbines can be placed to create energy. You can also reclaim the heat from the distilled water vapor and reuse it to distill more water. Also, vacuum jacketed lines can be used to reduce heat loss or to keep cool liquid refrigerant cool. There is a bit more to it but if you are like me you are already filling in the blanks.
I don't think the low levels of heat from AC's would travel to the coast in a cost effective way. Using solar conectrators on site would be more effective if you want hot water on site. Perhaps if the heat from the AC's in a highrise were used for cooking in a restaurant on the roof, that would be a more economical use of that excess heat? Alternatively, the wave pumps could pump up cold ocean water for cooling buildings and then once the heat was removed from the building, it could be used to run a closed loop anhydrous ammonia turbine to get some power output from the excess building heat.

這種設計並沒有抓到海浪發電的關鍵竅門，系統機械效率不會很高！
Why not use nuclear power
Nuclear is good as far as having basically no carbon emissions, and a high electricity output to operating cost ratio, but radioactive waste is still problematic. If someone came up with a way to reuse "spent" fuel rods from reactors, that would be very helpful. Actually, I think some researchers are already working on that. (Sorry, I don't have a link.)
Full of shit at all. The authors are very free to juggle facts, consciously focus on beautiful pictures and operate with non-system designations such as "two households". "two households" is a new word of science, why we have to know the power in kw, metal consumption per square meter, we have "two households" - it is Nobel prazer. Behind the scenes: 40,000 small pumps in marine design, 40,000 bases for their installation (the area is easier to concreted completely), about 80,000 kilometers of pipes for binding, 1,000,000 square meters of AISI 324 sheet steel (45,000 tons). And we can't remove energy for 2,000,000 households from this square kilometer. To be able to do this, it is necessary to cover a 20 times larger area with steel structures. Multiply everything except the pumps by 20 times. Add hurricanes that will destroy it all every year.

I find a new way to have the green energy , its better than this
ΗΑ ΗΑ ΗΑ
Not practical at all. No way you can build a system that is cheap to manufacture, anti-corrosive, low maintenance, and power isn't loss through Transmission over long distances. Dumb ideas come out of the best schools.
My projects are higher, contact me, thank you.
