Cant we produce electric power from sea water by making it to fall from a height?

Answer 1

yes we can

there's no need to make the water fall from a height

just arrange some plates against the tides

this technology is implemented in japan

Answer 2

yes certainly we can do so, but process of "making it to fall from a height" will be a costly & NON-ECONOMICALaffair. Because we have to spent some energy " to make it fall from a height" (i.e. to push it up to a height). Since a system efficiency is always < 100% we can not get back the energy which we have spent to take sea water to a height. But if there is a natural height diffrence is available with some other natural favourable situations, then we can realy prduce electricity from sea water.

Answer 3

Well, theoretically speaking, underwater falls can be used to produce electricity. Or, the same concept can be used with tidal energies. Arranging series of rotors perpendicular to the change in tide, you can produced electricity.

But, thinking from the practical sense! it's not very easy.
1. you have to send that electricity from sea or underwater back to homes and that can cost a lot.
2. you have to think about weather conditons, in the storm.
3. you have to think about changing currents and underwater animals which may interfere with the process.
4, and, sea water can be corrosive so you need continuous maintenance.
5. and, another thing is , tides occur only twice a day so it could mean that you cannot get energy for 24/7
Anyone got better ideas?

Answer 4

we can produce electricity from the waterfall.....but it is difficult process to take the sea water to the height and produce electricity.
rather than we can produce electricity from the sea water by fixing the turbine in the tidal wave... when there is a high tidal wave the turbine rotates in the direction of the wave so that the generator which is connected to the turbine rotates results in the generation of electricity.

Answer 5

No. Because we need to lift the water from sea to higher ground and energy generated will be less then the energy produced.

The ocean turbines are used in France in remote areas and on experimental bases power is generated but it is very expensive.

But it can be done.

Please read my article on the subject. It is done even to day by old Toledo Electric / Cleave land Electric power with fresh water.

How to Generate Power from Sea Water.
By
Minootoo


Lots of Power Company will sale power very cheap at non peak hours.

To generate power you will need a place that is160 ft minimum above sea level plus storage height. This then is a salt water or sea water lake.

There are places that can be suitable for such operation.

Engineering, Economic and Permit and other things like corrosion problem needs to be worked out. Say all goes well then this lake can be filled at non peak hours and at peak hours water can be discharged to generate the much needed power.

It could be close loop system isolated from the Ocean by two large lakes or open loop system with one lake and the ocean itself.


I like the advantage of close loop because there are less chances of pollution and minimum fish kill (one time and at make up water fill only).

Answer 6

Why do you need sea-water?
If its feasible electricity can be generated crudely or even profitably from any water source falling from a height.
we utilise the potential energy stored in falling water to run turbines which are attached to dynamoes, which generate electricity.

Answer 7

this type of Technology already in use. in Denmark and Japan , engineer built a barrier near the sea coast where the height diff is more then 6 mtr in high tide and low tide. the barrier wall contain water turbine sets, when high tide come water comes from out side to in side of barrier and rotate the turbine. similarly when low tide comes the water of inside barrier flow inside to out side. so turbine blade rotates continuously and produce electricity. cost of this project is so much high so that Indian government can not afford this type of project. so we can afford only conventional type of electrical generation technology.

Answer 8

do not comprehend some thing about brown gas, sounds slightly hocuss pocuss to me. yet you're accurate the conception of electroysis to remodel water to hydrogen and oxygen to then burn in an inner combustion engine is insanity. power in, electricity say one hundred gadgets, power out as sensible mechanical power 20 gadgets or a lot less. yet there's a fashion wherein including water to gas can strengthen gas performance and strengthen engine existence and cut back toxins. In a diesel engine including a small quantity of water into the gas leads to a cleanser burn, a lot less NOx production and slightly larger pressures. All this in turn improves mileage and decreases toxins. Down section is this is sensible to blend the water and gas gently on the micro element (extremely sonic instruments can try this) and water left interior the gas tank will reason corrosion and plausible gas blockages. So idealy the blend desires to ensue only as you inject the gas. plausible, yet complicated and expensive. Lab outcomes ensue to fifteen% improvements in distinct parameters. this isn't magic yet in accordance to combustion chemistry. i do not comprehend of any commercial instruments in accordance to this crucial. yet given the effectiveness, i experience some will be for sale if oil expenditures proceed to upward thrust. utilizing this technologies does not be elementary and it does not be lower priced. yet when mass produced it ought to reduce toxins tiers and bring about mark downs besides. (this study replaced into being performed interior the 70s, or maybe as oil expenditures fell back it replaced into abandoned.) The trick replaced into to introduce only the right quantity of water, too a lot and it decreased performance, too little and it had no result. From memory it replaced into between 2 and four% water. I had not some thing to do with this study, only study different papers.

Answer 9

Yes and we do. Lakes are used in a method called pumped storage. When electricity demand is low, water is pumped to a high altitude reservior and when there is high energy demand such as when everyone mum switches the kettle on during the break in coronation street the water is released, generating electricity.

Answer 10

Sure we can ! And i suppose you have a magic wand to first get the sea water up to the required height !!!
