Q: Where are some hydro-electric generating plants in the Boreal Shield ecozone?
Where are some hydro-electric generating plants in the Boreal Shield ecozone?
I know there are many because it generates less than 40% of total hydro-electric energy. I need to know a specific or biggest one. Thanks.

A: There are a series of dams and generators on the Manicouagan River in Quebec, of those the largest is known as Manic-5, output is a little over 1500 MW. The reference has a map of the Manic stations and specific info about them.

Q: What types of emissions are produced by coal farming power and hydro electric power plants?
What types of emissions are produced by coal farming power and hydro electric power plants and what are the effects of such emissions on human health and the environment?

A: Coal fired electric plants produce CO2, HCl, HCHO, CO, H2O, SO2, particulate… that covers the big ones. I’m not sure about hydro-electric plant emissions… If they just use the water to turn the turbines and generate electricity, they have no emissions. THis is not to say that they don’t have an environmental impact though. Hydro plants alter the water tables and can change entire ecosystems in the surrounding areas.

The coal plant emissions create smog, acid rain, and pump CO2 and H2O out in big quantities – these molecules absorb a lot of infrared energy, so they hold heat in the atmosphere.

Q: Is there a way energy is harnessed by the current beside hydro electric?
From what i understand damming and releasing water is the way hydro electric power is created, is is feasible or is there already a way developed to get power just by dropping or floating something into the middle of the ocean and collecting energy from the water movements? It seems to be there is an awful lot of perpetual energy just in the oceans moving around, what am i missing.

A: They have done something like this. But think about it for a second. Suppose you have a float that is 8 by 8. The ocean can move such a float maybe 1 meter. How much does such a float weigh maybe 200 pounds or about 900 N. These are just numbers. Work or energy produced 900N*1m = 900 J

How many watts is that? Say the 1 meter moves once a second.

Power = Work/time
Power = 900 J/1 second = 900 watts.

If you get 900 watts out of such an arrangement and you a 100% ability to change this mechanical energy to electrical energy, just what are you producing?

We could run 900/50 = 18 light bulbs. That’s just about a houseful of lights or maybe 1 toaster and no lights.

I live in a small community of 375 houses. How big do you think the float or series of floats would have to be to produce enough power to run our furnaces during winter. (We have cool weather roughly 8 months a year.) I think our furnace is about 1/3 horse power motor. I’ll leave you to figure out the wattage. During the winter, it’s on quite a bit of the time.

So you make your own judgements.

Q: is there a name for the generators found in hydro electric powerplants?
is there different types classes and names for generators (Of course) but what are they or at least the ones used in hydro electric powerplants. i need to know its stats like what torque is needed to spin at a certain rpm and how much wattage is generated @ a given Rpm. but the question im asking you is about the the type found in hydro electric dams, not its stats ill find that once i get the name. thanks in advance.

A: The generators used in hydroelectric power plants are synchronous alternating current generators. All synchronous generators are fundamentally the same but the speeds, mechanical configurations and other details for hydroelectric generators are different from steam turbine, gas turbine and diesel engine generators. Therefore, the generators used in hydroelectric plants are often called “hydroelectric generators.”

Q: Were can i find web sits for hydro electric dams?
i am doing this science project and i need web sits for Hydro electric dams. Please Help!

A: id recommend google try searching hydro electric dams if not this is one i found relyibale
http://ga.water.usgs.gov/edu/hyhowworks.html it tells you how one works

Q: In which of the following states ‘Koyana Hydro Electric Power Project’ is located?
In which of the following states ‘Koyana Hydro Electric Power Project’ is located
(i)Madhya Pardesh
(ii)Maharashtra
(iii)Kerala
(iv)Orissa

A: Located in Maharashtra state.

Q: What is the smallest level for hydro-electric power?
Is it possible to produce hydro-electricity using, a well, lake, or waterfall for a small village or town?

A: You can produce electric energy out of ANY stream. If you can build a dam, so much better, but there are hydro generators which can simply be dropped into the stream. Hire an engineer.

Q: which river has the largest hydro electric powerstation in NZ?
and which river in NZ has the most hydro electric powerstations

A: The largest hydroelectic powerstation in NZ is the Manapouri Power Station, but it doesn’t run off a river, it runs off Lake Manapuori – is this a trick question?

I think it’s the Waitaki River that has the most hydroelectic powerstations.

Q: Does turning off your lights really save water if your electricity comes from a hydro-electric dam?
Just curious as some BC Hydro informational people told me this today. It would make sense but does it directly or indirectly save water?

A: Yes!

While there are some minimum flow requirements at most dams for fish purposes, for the most part, the water is directed through the turbines to generate electricity.

The flow through the turbines is controlled by gates. As the demand for electricity falls off, the gates can be closed, retaining water behind the dams to be released later, either when electrical demand picks back up or if needed for fish flow.

Q: what is the smallest hydro electric dam in Washington State?
I know the largest one is the Grand Coulee Dam, but what’s the smallest?

A: One in somebody’s back lot making electricity from a small stream on their property so they can live off the grid. There are probably dozens or hundreds in the state, it is just that finding them would be difficult, especially if they used little or no damming of the water way to attract regulators. You might contact people who make and sell small hydro-electric plants and see if they will give you a reference to a user in Washington state that is using their smallest unit. And then you would miss someone who has done a do it your self unit with a homebuilt turbine or wheel driving a automobile alternator to charge batteries.

Q: What is the return on the investment dollar for hydro electric power?
I’ve been searching for the answer to this question for my science project, but I can’t seem to find it anywhere! >:[

A: 5% to 15% a year depending on conditions, so you make your money back but over a long period of time.

Q: How is Duterium (heavy water) derived as a by-product of Hydro-electric generation?
During the 1939-45 world conflict, the Germans harvested Duterium,a vital element for thier atomic bomb development program supplied from a Hydro-electricity generating plant at Telemark in Norway.

Why and how does the process produce this wierd substance which is almost undistinguishable fro H2O but so ominous in it’s potential?

A: the duterium production just happened to be located at a hydro-electric plant, its not a by-product of electricity generation.

duterium in itself is harmless. it naturally occurs in water. to increase the percentage of duterium in normal water, you split the water into hydrogen and oxygen by passing an electric current through it. normal water splits very easily, duterium does not.

Q: What is the main source of energy used to run both hydro-electric turbines and wind turbines?
Explain?

A: Mechanical energy as kinetic energy, the physical movement of a fluid, either water (hydroelectric) or wind (wind turbines — yes, wind counts a as a fluid for these purposes) moving the blades that spin up the turbine and thus create electricity

Q: What are some problems with nuclear energy, hydro-electric energy, and geothermal energy?

A: These are all good ways to supply energy without pumping more green house gasses into the air, but they all have some problems. Nuclear energy has nuclear waste which is hard to dispose of and lasts for a very long time. Hydro-electric usually requires damming up a river which is bad for the ecosystem of that river. Fish and other aquatic animals that usually swim up and down the river for food or migrations are then blocked by a dam. Geothermal energy is hard to achieve because so far we don’t have the technology to drill deep enough to reach the heat required to make it work efficiently, so this technology so far is only good where the heat of the earth is near the surface already.
