1. A parabolic trough works by mirrors reflecting sunlight at water, heating it up, then turns to steam used to turn a turbine.
2. A central tower power plant works by mirrors pointing at the sun to reflect energy
3. a problem is that it only works when the sun is shining.

   

1. A parabolic trough is a big curved mirror that focusses the sunlight to strike a pipe, and then the pipe gets so hot that it can boil water into steam, or ake electricity.
2. A central Tower Power Plant is where heliostats, big mirrors, which there are 1800 of, circle around the inside of a tower. The light is reflected to the top of the tower, where a fluid is turned very hot. That fluid, when hot, is used to make energy.
3. It is not always good to use sun as a source of enery, because in some places it is not always sunny, but is some other times, and in other places, there is never sun. In some places, it would work though, because there is sun, all of the time.

   

3. The problem with the solar panels is the $. Another problem is clouds and winter blocking out the sun.

   

1. How does a parabolic trough work? It focuses sunlight into a pipe the sunlight then goes through the pipe making it become very hot so hot it can boil water to make steam to make electricity.
2. How does a Central Tower Power Plant work? 1,800 turning mirrors help it work by reflecting the suns energy back at the tower making it hot enough to heat water.
3. What is one of the problems with using the sun as a souce of energy? One problem about using the sun as an energy source is the sun won't always be shining then we won't have any electricity.

3. The problem with the solar panels is the $. Another problem is clouds and winter blocking out the sun.

   

1.A parabolic trough is a curved mirror reflecting the light to a pipe in the middle. Then it boils water and uses the steam for energy.
2.1,800 mirrors reflect the suns rays to a tower in the middle of all the mirrors. It boils a liquid into steam and uses it for energy.
3.One problem with using solar energy is sometimes the sun,s not out.

   

3. The problem with the solar panels is the $. Another problem is clouds and winter blocking out the sun.

   

1. A parabolic trough is a curved mirror and it focuses light to hit the pipe and then it will get really hot so it boils water into steam, and then it can be used a s electricity.
2. The Central Tower Plant reflects light off of 1,800 mirrors. Then the light reflects back to the top of a tower in the center of the circle where the liquid turns very hot. Then it can be used as electricity.
3.When people use the sun as a source of energy its not always a good thing because it costs money to make them and the sun isn't always out and it could take a long time to make electricity that way.

   

3. The problem with the solar panels is the $. Another problem is clouds and winter blocking out the sun.

   

1. It's a highly curved mirror, it foces the sunlight at a pipe. It will cause steam wich will turn turbines, that make electricity.
2. Their are 1,800 mirrors, the mirrors will trun to face the sun atamtically. Sunlight will move to the top of the tower reflecting off of the mirrors. it will heat a liquid wich can then be used to make electricity.
3. A problem with solar power is it will not work at night or doring cloudy or fogy days were the sun is hidden.

   

3. The problem with the solar panels is the $. Another problem is clouds and winter blocking out the sun.

   

2.Sunlight is reflected off 1,800 mirrors circling the tall tower. The mirrors are called heliostats and move and turn to face the sun all day long.
Solar Two Project The light is reflected back to the top of the tower in the center of the circle where a fluid is turned very hot by the sun's rays. That fluid can be used to boil water to make steam to turn a turbine and a generator.

3.Highly curved mirror called a parabolic trough to focus the sunlight on a pipe running down a central point above the curve of the mirror. The mirror focusses the sunlight to strike the pipe, and it gets so hot that it can boil water into steam. That steam can then be used to turn a turbine to make electricity.

   

1. How the parabolic trough works is like this. It has a curved mirror and a pipe going through it. When the pipe stares to get really hot the water starts to boil, and when the water starts to boil it creates energy.
2. How a Central Power Plant works is it has little mirrors and they are called heliostats and they move and turn to the to the face of the sun all day. Then there is a tube and it has water in it and it starts to boil and reate energy.
3. A problem usng the sun the sun is that i is not always out and so the mirrors would not get the sun all the time.

   

1. A parabolic trough is a curved mirror. There is a pipe running down the mirror. The mirror focusses the sunlight to strike the pipe, then the pipe gets so hot, that it can boil water into steam and turns a turbine for electricity.
2. Sunlight is reflected off 1800 mirrors circling the tall tower. The light is reflected back to the top of the tower in the center of the circle where the fluid is turned hot. The fluid can boil water to make steam to turn a turbine and a generator.
3. One of the problems is that when the sun isn't out, and it's cloudy, there isn't any sunlight for electricity.

   

1.A parabolic trough is a highley curved mirror that focusses the sunlight on a long pipe. The pipe is is going down to the central point that is over the curved mirror. Then all of the liquids in the pipe get hot and turn into steam.That is a parabolic trough and ho it works.
2.A central tower plant is another form of solar plants to make electrcity from the sun. It is called Solar Project Two. In this project, the sun is reflected off of mirrors that are around the tower in a circular form. The mirrors turn when needed to face the sun. The light reflects back to the tower and the fluid is turned hot by the rays of the sun.
3. Solar energy can be unhelpful or inconvinent because if the sun isn't out that day, there is no energy. It is also expensive to purchase and esemble the mirrors and the towers or plants. If it is raining or even a light bit cloudy, the electricity is therefore affected.

   

1. Aparabolic trough works by having the sunlight run down the pipe and hen it runs down the curved mirror.
2. A Central Power Tower Plant works by sunlight is reflected off of 1,800 mirrors circleing the small tower. The heliostats (mirrors) all move and turn to face the sun all day long.
3. A problom that the solar energy has is that if it is not sunny or if it is raining, you have no electricaty/power. But if it is sunny you do have electricity/power.

   

1.A parabolic trough works by focusing sunlight off a highly curved mirror onto a pipe running down a central point above the curve of the mirror. The pipe gets so hot that it boils water into steam. The steam turns a turbine and makes electricity.
2.A Central Tower Power Plant works by reflecting light off 1,800 mirrors called heliostats that move to face the sun all day. The light is reflected back to the top of the tower where a fluid is turned very hot and turns to steam which turns a turbine and makes electricity.
3.The problem with using the sun as an energy source is it only works when and where the sun shines.

   

1. A parabolic trough is a huge curved mirror to focus the sunlight to strike a pipe and it gets so hot that it can boil water into steam.
2. A central tower power plant uses sunlight, which is reflected off 1800 mirrors called heliostats, circling the tower. Then the light is reflected to the top of the tower in the center of the circle where a fluid is turned very hot by the sun's rays. Then that fluid can be used to boil water to make steam to turn a turbine and a generator.
3. The problem is that it can only work while the sun is shining.

   

1. How the parabolic trough works is like this. It has a curved mirror and a pipe going through it. When the pipe stares to get really hot the water starts to boil, and when the water starts to boil it creates energy.
2. How a Central Power Plant works is it has little mirrors and they are called heliostats and they move and turn to the to the face of the sun all day. Then there is a tube and it has water in it and it starts to boil and reate energy.
3. A problem usng the sun the sun is that i is not always out and so the mirrors would not get the sun all the time.

   

1. A parabotic trought is a highly curved mirror. It works by foucusing the sunlight onto the mirrors, and then into a pipe running down the curve of the mirror.
2. The Central Tower Power Plant works by reflecting sunlight off 1,800 mirrors circling the tower. The light is reflected back to the top of the tower into the middle of the circles. A fluid is then made very hot. That is how the Central Tower Power Plant works.
3. The problem with using the sun a energy is that it only works when the sun is out.

   

1.A parabolic trough is a pipe running down the central point above the curve of the mirror focussing on sunlight. The mirror makes the sunlight to strike the pipes, so it gets hot that it can boil water into steam. Finally, the steam can be used to urn a turbine to make electricity.
2.Another way of solar power plants, to make electricity is called a Central Tower Power Plant. First, sunlight is reflected off 1,800 mirrors around the tower. The mirrors, heliostats move and turn to all the time. Next, the light is reflected back to the top of the towerin the Center of the circle where the liquid is made very hot by the sun's rays. Finally, that liquid can be used to boil water to make the steam turn a turbine and a generater.
3. The reason solar power is not always a good idea is beacuase you can only use it if there is sun out. If it it rainy, cloudy, or just not sunny you cannot use solar energy.

   

1. A parabotic trough works when it focuses the sunlight on a pipe running down a central point on a curved mirror. The mirror focuses on the sunlight to strike the point. The sunlight will boil the water which will turn to steam, the steam is used then to turn the turbine.
2. How a central tower power plant works is it has 1,800 mirrors that reflect the sunlight into a pipe that boils the water which is turned to steam that turns a turbine or a generator.
3.The problem with using the suns energy is it only works when the sun is shining.

   

1. A parabolic trough works by reflecting light onto a pipe so that water boils into steam which powers a generator.
2. A power tower uses many mirrors to reflect light onto a pipe in the middle so water turns to steam and powers a generator.
3. One problem is that the power genrators only work during the day when the sun is out.

   

- A parabolic trough is a way to get electricity by solar energy. Long, currved mirrors are lined up facing the sun. A heat transfer fluid runs through the sets of mirrors, capturing the sun's energy. The energy is then brought together for different ways to use electricity.
- A Central Tower Power Plant is anothe rway to get electricity from solor energy. Many mirrors are circled around a tall tower. The energy form the sun hits the mirrors and then is reflected off the mirrors to the tower. Inside the tower there is a fluid that gets scalding hot by the sun's rays. The fluid is then used for electrical uses.
- The problem with using the sun's energy is that it only works when the sun is out. Humans also use a lot of solar energy, if we always use large amounts of the solar energy the other living organisms may suffer on our behalf.

1. How does a parabolic trough work?
A parabolic trough is a curved mirror that is used to provide solar energy. The sun hits the pipe in the center of the mirror. The sun makes the pipe get so hot it can boil water into steam. That steam is used to make electricity.
2. How does a Central Tower Power Plant work?
The tall tower is made of 1,800 mirrors that reflect the sun. The mirrors or heliostats move toward the sun all day long. The light from the sun’s rays makes the fluid turn extremely hot. The fluid is used to boil water to make steam, turn a turbine, or power a generator.

3. What is one of the problems with using the sun as a source of energy?
One problem is that if it was a rainy day the sun wouldn’t come out and there would be no energy.

1. The way a parabolic trough works is that it focusses sunlight into a pipe into Central point above the curve of the mirror. The mirror focusses the sunlight and strikes the pipe it gets so hot it boils the water into steam that steam is used to turn a turbine which makes electricity
2. Central tower power plant is another way to get energy sunlight is refleated off of 1,800 mirrors that circles the tower. mirrors turn and face the sun all day. Light is reflected to the top of the tower into the ceter of the circle. In the center of the circle fluid is turned very hot by the sun that fluid can be used to boil water into steam which can turn a turbine and a generator.
3. Problems with solar energy is that the sun is not out all the time. Sometimes it can be a cloudy day or it can be night time.
