How do you separate hydrogen and oxygen gas after you make it from electrolysis?

Use a distillation column. It cools down the gases to below the boiling point of oxygen at high preassure. Oxygen condenses and forms a liquid that can be tapped from the column while hydrogen remains a gas. Why not separate the electrodes used in the electrolyzation process and trap hydrogen at one and the oxygen at the other? It is a lot easier, and probably a lot less dangerous (as a hydrogen and oxygen gas mixture is explosive).

What force is used to generate hydroelectricity?

Hydroelectricity is generated by the force of flowing or falling water, typically from a dam or a waterfall. This force is used to turn turbines connected to generators, converting the kinetic energy of the water into electricity.

What energy transfer takes place when the turbine turns the generator?

Mechanical energy from the turbine is transferred to the generator, where it is converted into electrical energy. This process occurs through electromagnetic induction, where the motion of the turbine causes the magnetic field in the generator to change, inducing a flow of electric current.

What is energy from moving water?

Energy from moving water, also known as hydrokinetic energy, is a renewable energy resource that harnesses the kinetic energy of flowing water to generate electricity. This can be achieved through technologies such as hydroelectric dams, tidal turbines, and wave energy converters. Hydrokinetic energy is considered a clean and sustainable source of power with minimal environmental impact.

How does dinorwic power station works?

This is a pumped storage hydro power plant. It enables one of a very few ways to store electricity. The principle is that electric power from the grid is used at times of surplus to pump water up into a reservoir, then the water can be released to provide power at a time when there is a demand that the grid is having difficulty meeting, or when providing this power would be more expensive.
The engineering of the plant relies on hydro pump/turbines which can carry out either duty, and in fact can quickly reverse in duty if required. The generating mode can be reached in a few seconds if needed, to compensate for instance for another unit on the grid tripping out.

How does a generator turn energy in to power?

The electric generator converts mechanical rotation (hence, the term mechanical energy) into electrical energy (electricity) with the help of magnetism in the generator (magnetic forces). Electric power is the term use in expressing the rate of energy per time (hence kilowatt = kilojoule per second).

In a complex electric power system, this electrical energy is converted back into mechanical energy (such as elevator in a building, refrigerator at home) and other forms of energy that are being use by mankind in its quest for development

Does a fast moving stream use energy?

Yes, a fast-moving stream uses energy to maintain its flow velocity. The energy comes from gravity, which causes the water to flow downhill and overcome resistance from friction with the stream bed and banks.

Is there such thing as unconducted wet electricity?

No, wet electricity is a term used to describe water that has been electrified by contact with live electrical circuits. There is no such thing as unconducted wet electricity because water itself is a conductor of electricity.

What is hydroenergy?

Hydroenergy, also known as hydropower, is energy derived from the force of moving water, typically generated by the flow of rivers or water released from dams. This renewable energy source is harnessed through water turbines to produce electricity, providing a sustainable and clean alternative to fossil fuels.

How does flowing water generate power?

Flowing water is used to generate power through hydroelectric power plants. The power of flowing water spins turbines, which are connected to generators to produce electricity. The potential energy of the water is converted into kinetic energy, which is then converted into electrical energy.

What is the energy transformation in Water Wheels?

In water wheels, the kinetic energy of moving water is transformed into mechanical energy as the water flow turns the wheel. The mechanical energy can then be used to drive machinery or generate electricity through a generator attached to the water wheel.

How do you make a homemade water wheel and produce electricity from it for and assignment?

To make a homemade water wheel, you can use materials like wood, buckets, and a small generator. Attach the buckets to the wheel so that they catch flowing water and turn the wheel. The rotating wheel can then be connected to a small generator to produce electricity. Ensure the setup is secure, and be cautious when working with water and electrical components.

What would happen to the world if hydro power ran out?

Hyrdo power is derived from the movement of water downhill, so the only way that hydro power could run out would be if water stopped flowing. That is a bigger problem than a lack of electricity. Of course while hydro power is renewable it is also finite (and comes with a cost to the environment). After all the possible avenues for getting hyro power has been exhausted the world will either have to make to without new energy sources or use the sources it does have more wisely.

How is hydro power better than wind power?

Hydropower is a more consistent and reliable source of renewable energy compared to wind power, which relies on wind availability. Hydropower also has the ability to store water in reservoirs for peak demand periods, providing better control over electricity generation. Additionally, hydropower tends to have a longer lifespan and can contribute to flood control and irrigation.

How is hydro power energy gathered?

The energy we can get from the movement of water or from the force of water flow is called hydropower. It produces electricity as it flows towards a turbine, spinning the turbine and activating the generator.

How can sugar water make metals rust?

it has water, so I'm assuming yes. And remember, the only metals that rust have iron in them. For example, copper does not rust. However, it does oxidize, turning it that funny green color. Be careful of the terminology you use.

How does water make electricity?

Water, as it flows downhill can be made to spin turbines. These turbines can be used to move electromagnets through electrical coils. The motion of magnets, though coils generates electricity through a process called induction.

How many hydroelectric power stations are there in Britain?

There are around 2,000 hydroelectric power stations in Britain. These power stations generate renewable energy by using the flow of water in rivers and streams to turn turbines and produce electricity.

Does hydroelectric energy come from the sun?

Technically, hydroelectric energy ultimately comes from the sun. This is because the sun's energy heats up water, moving water through the water cycle. Hydroelectric energy is generated by harnessing the power created by the movement of this water.

What liquids conduct electricity?

Some common liquids that conduct electricity include water (when it contains dissolved salts or minerals), acid solutions (such as vinegar or lemon juice), and some ionized liquids like saltwater or electrolyte solutions. Pure liquids like oil or distilled water are poor conductors of electricity.

Does water have energy?

Yes, water has energy in the form of kinetic energy and potential energy. Kinetic energy refers to the energy from water molecules moving, while potential energy refers to the energy stored when water is held at a certain height.

Which dams use tidal power?

A dam used for tidal power is called a barrage.

Such dams exist in a number of places:

Rance River, in France

Bay of Fundy, in Canada

Kislaya Guba, in Russia

Other barrages are under consideration. See the related link, below, for more information.

The force used to create hydroelectricity is?

The force used to create hydroelectricity is the kinetic energy of moving water, typically from a dam or flowing river. This energy is harnessed and converted into electricity through the use of turbines connected to generators.

What is a Pumped Storage Reservoir?

When there is not much demand for electricity, such as during the night, the extra electricity is used to pump water back up to a storage reservoir. Then, later in the day, when electricity demand is high, the water from the storage water is also released as an extra, producing more electricity when it is needed.

If carbon were used as nuclear fuel it would be best?

Carbon is not commonly used as nuclear fuel because it does not readily undergo nuclear fission reactions. Elements such as uranium and plutonium are more suitable for use as nuclear fuels due to their ability to sustain nuclear chain reactions.
