Solar Power

A photovoltaic (PV) system needs unobstructed access to the sun's rays for it to work. Shading on the system can significantly reduce energy output. Climate is not really a concern, because PV systems are relatively unaffected by severe weather. In fact, some PV modules actually work better in colder weather. Most PV modules are angled to catch the sun's rays, so any snow that collects on them usually melts quickly. There is enough sunlight to make solar energy systems useful and effective nearly everywhere in New York.

The prickly pear cactus [Opuntia spp] gets its energy from photosynthesis. The photosynthetic interaction takes place between the plant and the sun. The sun supplies the necessary light, and the plant supplies the necessary dissolved nutrients. The result is energizing photosynthetic products.

The wings. These are used to bring their blood up to temperature which flows through small capillaries within the wings. The butterflies open their wings to the sun to expose them to sunlight.

Solar energy keeps the earth warm. The increase in solar energy trapped by greenhouse gases is causing global warming and climate change. This will destroy the habitats of some animals, initially the polar bear.

Photosystem II takes 680 nm red light and as it absorbs it, particles of different colors resonate and energize chlorophyll a which then retron by being excited. After, the electron gets joined by another one and H+ ions are following along while they get transported through electron trsnaport proteins such as Pq, PC and then go through cytochrome b6f. Then, the sunlight hits Photosystem I at 700 nm red light and the electrons get transferred to the Fq, then it goes through NADP synthase, creating NADPH+ H+. After that, the concentration of H+ ions are excessive in the thylakoid membrane, so ATP synthase shoots out some H+ into the stroma.

Most of it is absorbed as heat. The green wavelengths of light are reflected. The blues and reds are used to excite electrons to trigger pathways to create NADPH, ATP and oxygen. Eventually glucose will be made as well. This glucose can then be stored or used in cellular respiration.

Plants use energy from the sun together with nutrients from the ground, water, and some gasses from the atmosphere to grow.

Then animals can eat the plants, and humans can eat both animals and plants.

So pretty much all energy being used on Earth, apart from nuclear energy and thermal energy once came from the sun, one way or another.

Answer

the energy of the sun is used by people to other energy in the earth thats why the sun is called the main energy source of the earth then it helps provide vitamin D for the plants, it helps them to make sugar and carbon dioxide it helps them maketheir own food .for the animals , it helps them heat the body especially mamals that has thick fur.

True...

Animals such as lizards in the desert get energy from the sun by getting its heat but most animals get it from plants that have taken in the energy through photosynthesis.

Cooking it covered will cook it faster as it keeps the heat in the food, and if your cooking meats will help to keep the juices in. Uncovered foods will bake faster on the outside possibly buring before the inside gets fully cooked.

Short answer 150° C (300° F).

My personal cooker only reaches 130 degrees, but a friend of mine has recorded his at over 150° C (300° F)! You only need about 90° C (200° F) to sufficiently cook food, and most box-style solar cookers (even if you've made mistakes in making your cooker) have no problem meet this temperature. Make sure to measure the temperature inside your cooker before trusting it to cook anything though. I suggest trying to boil water, which boils at 100° C (212° F), or using a thermometer. Some more advanced panel designs and parabolic cookers can get just as hot or hotter than a stove-top burner!

There are pickles, onions, peppers and other foods that are pickled: they are stored in a vinegar brine for a long time. Lots of foods that used to be considered short term are preserved in a refrigerator or a freezer, like milk and other dairy products. Lots of foods can be frozen and kept for longer, like meat, vegetables, soups, pastries, etc. Foods can be stored in cans in a special way so they don't spoil for a long period of time. These are usually vegetables, beans, fruits, nuts, etc.

Some foods - fruits, beans, etc. - can be dried so that they last longer.

It is a Non- Renewable source of energy because when food is waisted and it runs out it cannot be renewed.

Basically, a solar box cooker is a tin foil lined box. Food is placed inside and the box is pointed towards the sun. A glass cover keeps out draughts and traps the heat inside. The tin foil lined top of the box is angled to concentrate the rays directly towards the food.

The cooker is well insulated, so it stays hot.

A solar cooker, also called a solar oven, is simply a cooking device that uses energy from the sun to cook food. It doesn't require any electricity, which makes it the perfect cooking device to use in remote areas or areas where there is no access to a power grid. The solar cooker has three major functions. The first function is concentrating the light from the sun into one small area. Reflective materials are used to do this, and the result is that the heat is more concentrated in the solar cooker. The second function is turning the sunlight into heat. This is accomplished by using a substance that can absorb the heat from the sun and store it for cooking purposes. The third function is trapping the heat created by the sunlight. Trapping the heat helps to cook food more evenly and means that the solar cooker can be used on both hot and cold days.

because the heat

it's pretty safe to cook in a solar oven, but it can catch on fire just like any other oven

Try using a magnifying glass by placing it over the hotdog and letting the sun's rays shine on it. It works when frying ants, so it might work to cook a hot dog.

what above me is wrong this is not a song.....

A lot of crystal will be lead crystal (at least in part). Please don't! Especially if it's old crystal.

Solar cookers come in different forms based how they absorb the sun's rays. Some of the most popular types of solar ovens are solar concentrating ovens, solar reflective ovens, and solar absorption ovens. Each provides a reliable, low-cost solution for cooking so you can keep the heat out of the kitchen.

Solar cookers are great for camping trips or outdoor cooking where electricity and fuel are far out of reach. If you're worried about losing cooking power when the sun retreats behind the clouds, some companies manufacture hybrid solar ovens that can be plugged into an electrical outlet. In the absence of sun, an electrically powered infrared heat source keeps the internal chamber at the proper cooking temperature.

You first have to decide what kind of solar you wish to use.

Solar Electricity.

Solar Hot Water (not necessary for a model house, but good to consider for a real house.

Solar heating (passive or active).

Each of the above solar systems have some things in common and some things that would be different. The solar heating probably should be integrated into the home design, but there are a few "soda can" solar heating designs that you might consider.

Ok, now decide what kind of house you wish to use/build. Perhaps you can find an existing dollhouse that would have a little character.

Solar-Electric will be the most spectacular. You might want to do a little testing in the environment where you will display the house. Solar cells usually give about 0.5 volts per cell. An LED requires about 1.5 to 2 volts to run effectively. Too much power and it will burn out, too little and it won't light. However, your power generation of an individual solar cell will be significantly less inside a building than it will be in the direct sunlight.

Most solar-electric home systems use one of 2 types of power. "Battery off grid", or "Grid Attached without batteries". The grid attached gives you power 24/7 no matter what the weather is like. Battery off grid will run out if your batteries run out. A 1.5 volt rechargeable D battery or a pair of them should be sufficient to run LED many lights (possibly requiring a resistor if using a pair), but they would be able to be turned on with or without solar light. For Demo purposes it might be more interesting to build without the battery.

Wire your house with phone wire & LEDs or something similar. Determine the size and number of solar cells you need. Use serial connections to increase voltage and parallel connections to increase power (amps/watts). Resistors can be used for fine adjustments of volts to protect your LEDs. Mount on the roof, with a toggle switch for cutoff.

Solar hot water panels would be "dummy panels") Probably painted black. Weave single stranded electrical wire on the panel to look like pipes, then paint it all black & mount.

If you wish to make a soda-can solar panel, representing the cans with smaller materials might be difficult. Maybe you could find some small rollerbearings and tear them apart and assemble. Talk, to your local mechanic and see if he has some extra wheel bearings that you could play with. You'll need quite a few of them.
A full sized model of the soda-can solar panel would also be a fun demonstration to have on hand, and would be relatively easy to make.

Good luck with your project.

Some solar calculator contain batteries so that they can continue to operate in the shade.
