Is hydroelectric power reliable?
More reliable than most other forms of electricity. Water flows down hill. As long as the lakes and rivers that are feeding the hydroelectric station don't dry up, they will always generate electricity. You will never run out of gas or uranium or coal to power the plant.
How much surface area is needed to make 1 liter of HHO gas per minute with an electrolyzer?
The issue is not only surface area. Electrolysis (with an acidic electrolyte) involves the diffusion of H+ ions to the cathode. This requires an electric field to separate the H+ ions from the water molecule at the anode, and to drag the ions across the electrolyte to the cathode. Of the supplied electrical energy, only about 5.2 V is needed to break apart two water molecules. The rest is used to fight the resistance of the electrolyte. So the problem is not just a matter of area, but how close together the electrodes are, how acidic (or basic) the electrolyte is, what the temperature is, and what the supplied voltage is. It also depends on the metals you have used for your electrodes.
To make this simple though, at 12 volts, you will need approximately 19 amps of current to make 1 L of HHO gas per minute. This assumes a 50% efficiency. If 'x' is the current for your test electrodes, then multiply the area of your electrodes by 19 and divide by x. The result will be approximately the final electrode area you will need to produce 1L / min for your separation, concentration, and temperature.
Alternatively, current is proportional to area, and HHO production is proportional to current. So you could measure the HHO production for your test electrodes, and then divide the area of the test electrodes by the number of liters of HHO gas they produced in a minute. This will tell you the final area you will need.
What are the adantages of hydroelectric power?
Once the dam is built and the power plant installed, there are no fuel costs and no pollution
The lux is the SI unit of illuminance, and is equal to 1 lumen per square meter.
Hydro power was invented because a clean renewable energy source was needed. The world's supply of coal and oil are being used up, and those resources are not renewable.
Who invented hydroelectricity?
Hydroelectric power, that is the mating of centuries-old hydraulic power machines, such as waterwheels and turbines, with electric generators was a foregone conclusion once generators became commercially available. Although the first generating station was steam-powered, it must be remembered that steam engines were used at that time primarily as a substitute for water power in locations were water power was not available.
Lester Allen Pelton is commonly mentioned as the inventor of hydroelectric power. This is not true. Pelton invented a type of hydraulic turbine that used a free-jet impulse system to turn a wheel; he patented his Pelton turbine in 1880. Pelton wheels were widely used to provide mechanical power for mining operations in the mountainous country of the western US. In 1887, miners connected a generator to a Pelton wheel and began generating electricity, but Pelton himself had nothing to do with this development.
Five years earlier, in Appleton, Wisconsin, the Vulcan Street Plant went into operation on September 30, 1882. It generated electricity using the power of water from the Fox River already impounded by a dam at an existing paper mill. The plant was the brainchild of two men: H. J. Rogers, president of the Appleton Paper and Pulp Co. and the Appleton Gas Light Co., and H. E. Jacobs, who was a licensing agent for the Western Edison Light Co. of Chicago. The two men were friends, and it is believed that they developed the idea while on a fishing trip together. The Vulcan Street Plant is considered to be the first hydroelectric generating station in the world.
Lester Allan Pelton was an American inventor who created an efficient form of impulse water turbine in 1878 in the goldfields.
In 1887 a miner attached Pelton's wheel to a dynamo and produced the first hydroelectric power in the Sierra Nevada Mountains.
Just to let everyone know hydroelectric power wasnt created. He just discovered it and found ways to use it.
Nikola Tesla developed the first working system at Niagara Falls. The system is still over on the Canadian side with a statue of the man. Quite a work of engineering excellence.
What are the good uses about hydroelectric power?
Hydro electricity is good because water is all around us. This means that we do not need to change the entire landscape dramatically. Next we have the fact that it is cheaper due to the fact that at one time there are very little personnel on the floor resulting in lower costs for the customers. Now I look at the structure of the dams they use. The dams are strong and some built hundreds of years ago are still in use today. There are also low emissions, however, the emissions are only from the building process. Finally I turn to how much power hydro-electricity makes. With the amount of dams we have today we could power the world two times over! And for all those tax payers and people that want to keep their money, going to hydro electricity is a very good decision to make.
Hydro energy (hydroelectricity) is electricity made by using a moving water source (kinetic energy), usually a river, falling by gravity (potential gravitational energy) to turn electric generators. It is the most common form of renewable energy.
How much money would hydroelectric energy save?
it would probaly save alot of money bcause it is used to produce water energy and electricity.that is a two for one special.
Water turbines make water do work. Usually they are used for making electrical power.
What times do the turbines turn on at guntersville dam?
call 1-800-238-2264
When calling automated service punch 4 for discharge rate, then punch 29 for the guntersville dam.
it is used almost everywhere!
Hydropower is the energy captures from moving water and it has been used since the beginning of time. It is typically used to make electricity and often comes from dams.
Once hydroelectric power is placed on the wires and stepped up to the transmission system level, it can power anything that can be powered by any other means. Let me let you in a little secret; hydro power can clear itself from a dead system and power itself, and then it can power a substation nearby to enable gas powered plants to get its themselves started -- to eventually bring an entire transmission system back to life. There is a use for hydro power.
To get electricity.
drinking water, lakes and ponds
hydro power is to power up homes in the world using water to make electricity.
Everything that conventionally generated electrical energy is used for can also be powered by hydroelectricity.
What is hydroelectricity used for?
The same things all other electricity is used for. Home use ... lighting, heating, etc. Business/ industry uses, electrolysis of (purification of) metal ores, welding, lighting, heating, computers, anything you can think of.
Precisely the same as the uses of electricity.
Same as for any electricity. The hydro bit is to do with how it is made. After that it is just like any other electricity.
Hydroelectric energy is electricity produced from the power of water being pulled by gravity through turbines. It is just electricity. It is no different from electricity produced by any other means.
It is used just like normal energy, to power homes, industries, streetlamps, the computer you're using etc.
Use of flowing water to create electricity is called hydroelectric energy. The most common type of hydroelectric plant uses a dam on a river to store water in a reservoir. Water released from the reservoir flows through a pipe and into a turbine, which spins to drive a generator, producing electricity.
Pumped storage plants use a two-reservoir system, pumping water from a river or a reservoir to a higher reservoir when electricity prices are low during the night. When the value of electricity on the grid is higher during the day, water is released from the upper reservoir, spinning the turbines to produce electricity.
it is used to light our homes ,industries etc
You use hydroelectric energy to get electricity from moving water. the hydroelectric power plant is mostly located at a river that's on a slope. then, they make a dam, which is the power plant.
powering lights houses and other things.
In other words hydroelectric stuff powers electricity
In most countries it just goes into the electricity distribution network, so it is not possible to say. There may be some isolated places that only have hydro power, but in any case it is used for all the usual things we use electricity for
it it used to power many places like homes and businesses.
Hydroelectric power is a specific type of electrical power that is generated through using water (typically falling water) to turn a turbine that spins turbines that generate electricity. The electricity is used in the same fashion as all other electricity generated from burning fossil fuels or from solar panels is used - to power electric appliances from refrigerators to cell phones.
The Tennessee Valley Authority Act created a public corporation that was authorized to build dams and electrical generating-plants.
What are the positive aspects of using hydroelectric energy?
One advantage of using hydroelectric energy is that it is a renewable source of energy. Other positive aspects include a guarantee in energy and price stability as well as its feasibility in utilizing other renewable sources.
How much money do you save using biomass energy?
Using Biomass can save the average consumer about $8,000 per year.
When and where was hydro energy first invented?
The Romans in Rome had water clocks, powered by running streams by the end of the 1st Century. They also used water wheels to power sawmills, crush ore, mill corn and pump water for their aqueducts.
How do pumped storage reservoirs work?
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.
Why is sustainable energy important?
Because non-renewable sources are...well...non-renewable? They won't last forever. Renewable resources can be renewed. Congratz
How much energy can be produced in 2 hours by a hydroelectric power plant?
The biggest Hydro plant in Norway is Kvildal with an effect of 1240 MW per hour. So about 2500 Mw. But there are far bigger powerplants in the world with higher effect than this.
How can Louisiana use biomass?
Louisiana has many biomass resources such as timber, sugarcane, cotton and various other crops. Any of the biological by-products of agriculture as well as municipal waste could be used to generate electricity. The sugercane could be fermented to make ethanol for use in automobiles.
