Why electricity not generated with sea waves?( I think atleast coastal towns benefit from this.)?

Answer 1

It has been done. San Francisco is planning to study this near the Golden Gate. There, it's more tidal than wave energy but others are trying to harness waves as well. Drawbacks include risks to and from boats, swimmers, and marine life. It's a rather harsh environment, especially during storms. Your structure needs to survive the waves as well as draw power from them.

If that's not enough to discourage you, realize that if you succeed, environmental extremists will try to shut you down, just as they are doing to traditional hydroelectric generation.

Answer 2

some do.
There are some ways of converting wave energy to electricity.
But there are some drawbacks.
1 open sea lanes, you can not block boats moving about.
2 coruscation's, things in the seas will grow and build up makes for less energy.

They make a row of floats that bend in the waves the generator is in the bend of the floats. simple but things will grow.

Another is a wave piston as air or a float in a pipe is pushed up or down by the rise and fall of a wave. and they too get gummed up over time.

Big wind farms are at sea in shallow waters where boats cant go.


Iceland has geothermal gemerators. Heat runs turbines for electricty. no need for wave energy ( they could be running test but they dont need it)

Answer 3

solution may be in thinking small.

little generators, the size and cheapness of your computer fans could be woven into fishnets and deploted cheaply.

when they crud over (which they will) the nets can be pulled back in for cleaning/recycling

i also recall hearing about "ducks" some sort of bobbing up and down in the waves generator

Answer 4

There are various reason. at the start, the climate. climate in the united kingdom is unpredictable, and that they purely have a short summer time era. this suggests that there is in basic terms a constrained quantity of sturdy sea coast climate and additionally you are able to on no account ascertain while it is. Secondly, lots of the united kingdom's seafronts have been fishing cities or Victorian vacationer motels, and while the two a form of issues dried up belongings expenditures fell in the coastal motels. This convey approximately neighborhood governments sending inner city adverse to stay there. often the circumstances have been adverse (Small apartments, often with shared kitchens and lavatories and no backyard area), and frequently the people have been the two socially undesirable (drunkards, drug addicts or purely uncomplicated anti social) or they have been actual criminals. This convey approximately many areas jointly with Brighton and Hastings to alter into ghetto like areas, poorly planned housing projects with significant social issues. Who'd want to be a vacationer in a chilly damp section with lots of bored exported inner city adverse striking around the streets? ultimately, the united kingdom on no account somewhat promoted its coasts appropriate. they're often promoted as a decrease priced option to a overseas holiday meaning that the travelers that they charm to are frequently much less prosperous households. this suggests people who like "much less state-of-the-artwork" leisure, jointly with ingesting and undesirable night golf equipment. this style of vacationer and this style of leisure isn't appropriate for attracting state-of-the-artwork travelers, who often flow to the cities and cities the place issues are extra costly, yet the place there are fewer drunks and drug addicts and drunken travelers. of path, there are exceptions to this.

Answer 5

that technology far to expencive for any town to afford is all about cost effectiveness is cheaper to run miles and miles of wires from the nearest dam or build solar pannels

Answer 6

I think I read somewhere that Iceland has some generators that do that.
