HELLLPPP MEEEEE PLSSSS BRANLIEST ANSWER WILL BE AWAREDED Prepare a report on how is solar energy used in scientific experiments.

Answer:

SOLAR ENERGY

Our primary source of clean, abundant energy is the sun. The sun deposits 120,000 TW of

radiation on the surface of the Earth, far exceeding human needs even in the most aggressive

energy demand scenarios. The sun is Earth’s natural power source, driving the circulation of

global wind and ocean currents, the cycle of water evaporation and condensation that creates

rivers and lakes, and the biological cycles of photosynthesis and life. Covering 0.16% of the land

on Earth with 10% efficient solar conversion systems would provide 20 TW of power, nearly

twice the world’s consumption rate of fossil energy and the equivalent 20,000 1-GWe nuclear

fission plants. These comparisons illustrate the impressive magnitude of the solar resource,

providing an energy stream far more potent than present-day human technology can achieve.

All routes for utilizing solar energy exploit the functional steps of capture, conversion, and

storage. The sun’s energy arrives on Earth as radiation distributed across the color spectrum

from infrared to ultraviolet. The energy of this radiation must be captured as excited electronhole pairs in a semiconductor, a dye, or a chromophore, or as heat in a thermal storage medium.

Excited electrons and holes can be tapped off for immediate conversion to electrical power, or

transferred to biological or chemical molecules for conversion to fuel. Natural photosynthesis

produces fuel in the form of sugars and other carbohydrates derived from the reduction of CO2 in

the atmosphere and used to power the growth of plants. The plants themselves become available as biomass for combustion as primary fuels or for conversion in reactors to secondary fuels like

liquid ethanol or gaseous carbon monoxide, methane, and hydrogen. We are now learning to

mimic the natural photosynthetic process in the laboratory using artificial molecular assemblies,

where the excited electrons and holes can drive chemical reactions to produce fuels that link to

our existing energy networks. Atmospheric CO2 can be reduced to ethanol or methane, or water

can be split to create hydrogen. These fuels are the storage media for solar energy, bridging the

natural day-night, winter-summer, and cloudy-sunny cycles of solar radiation.

In addition to electric and chemical conversion routes, solar radiation can be converted to heat

energy. Solar concentrators focus sunlight collected over a large area to a line or spot where heat

is collected in an absorber. Temperatures as high as 3,000°C can be generated to drive chemical

reactions, or heat can be collected at lower temperatures and transferred to a thermal storage

medium like water for distributed space heating or steam to drive an engine. Effective storage of

solar energy as heat requires developing thermal storage media that accumulate heat efficiently

during sunny periods and release heat slowly during dark or cloudy periods. Heat is one of the

most versatile forms of energy, the common link in nearly all our energy networks. Solar thermal

conversion can replace much of the heat now supplied by fossil fuel.

Although many routes use solar energy to produce electricity, fuel, and heat, none are currently

competitive with fossil fuels for a combination of cost, reliability, and performance. Solar

electricity from photovoltaics is too costly, by factors of 5–10, to compete with fossil-derived

electricity, and is too costly by factors of 25–50 to compete with fossil fuel as a primary energy

source. Solar fuels in the form of biomass produce electricity and heat at costs that are within

range of fossil fuels, but their production capacity is limited. The low efficiency with which they

convert sunlight to stored energy means large land areas are required. To produce the full 13 TW

of power used by the planet, nearly all the arable land on Earth would need to be planted with

switchgrass, the fastest-growing energy crop. Artificial photosynthetic systems are promising

routes for converting solar energy to fuels, but they are still in the laboratory stage where the

principles of their assembly and functionality are being explored. Solar thermal systems provide

the lowest-cost solar electricity at the present time, but require large areas in the Sun Belt and

breakthroughs in materials to become economically competitive with fossil energy as a primary

energy source. While solar energy has enormous promise as a clean, abundant, economical

energy source, it presents formidable basic research challenges in designing materials and in

understanding the electronic and molecular basis of capture, conversion, and storage before its

promise can be realized.

Why did Dante most likely choose to write his views on Christianity in an
indirect manner when he wrote the Divine Comedy?
• A. He was not sure of his exact views on many Christian values, so
he left room for personal interpretation.
•
B. He knew his audience would be larger if he wrote an entertaining
story that waug't too serious.
• C. He wanted to represent Christianity in a positive light but felt the
state of the Church was too negative.
• D. He wanted other writers to imitate his style of avoiding direct
character conflict.

I was climbing up a mountain-path

With many things to do,

Important business of my own,

And other people's too,

When I ran against a Prejudice

That quite cut off the view.

My work was such as could not wait,

My path quite clearly showed,

My strength and time were limited,

I carried quite a load;

And there that hulking Prejudice

Sat all across the road.

So I spoke to him politely,

For he was huge and high,

And begged that he would move a bit

And let me travel by.

He smiled, but as for moving! —

He didn't even try.

And then I reasoned quietly

With that colossal
mule:

My time was short — no other path —

The mountain winds were cool.

I argued like a Solomon;

He sat there like a fool.

Then I flew into a passion,

and I danced and howled and swore.

I pelted and belabored him

Till I was stiff and sore;

He got as mad as I did —

But he sat there as before.

And then I begged him on my knees;

I might be kneeling still

If so I hoped to move that mass

Of obdurate
ill-will —

As well invite the monument

To vacate Bunker Hill!

So I sat before him helpless,

In an ecstasy
of woe —

The mountain mists were rising fast,

The sun was sinking slow —

When a sudden inspiration came,

As sudden winds do blow.

I took my hat, I took my stick,

My load I settled fair,

I approached that awful incubus

With an absent-minded air —

And I walked directly through him,

As if he wasn't there!
