Solar Face Was the dark side of the moon facing the earth on the day of solar eclipse?
Since some parts of the world (e.g. China) was into complete darkness for sometime on the day when the eclipse of the sun occurred; Was it because the dark side of the moon was facing the us (earth)? Why didn't the moon look like a moon on normal night? I mean usual white/silver moon... why was it dark?
Yes, the dark side of the Moon was facing the Earth on the day of the eclipse. We only see the Moon (aside from during a Solar eclipse) because it relects the light of the Sun. During a Solar eclipse, we see none of the illuminated side of the Moon because it is between the Earth and the Sun. We are facing the dark side at that time. We only see it because it is eclipsing the sun. We see a dark circular shape obscuring the Sun.
In the face of mounting concern about climate change, this documentary from NOVA explores the renewed struggle among scientists to make solar energy a realistic, reliable, and efficient solution to our energy needs.

Soleil cou coupe (Solar Throat Slashed) is Aime Cesaire`s most explosive collection of poetry. Animistically dense, charged with eroticism and blasphemy, and imbued with an African and Vodun spirituality, this book takes the French surrealist adventure to new heights and depths. A Cesaire poem is an intersection at which metaphoric traceries create historically aware nexuses of thought and experience, jagged solidarity, apocalyptic surgery, and solar dynamite. The original 1948 French edition of Soleil cou coupe has a dense magico-religious frame of reference. In the late 1950s, Cesaire was increasingly politically focused and seeking a wider audience, when he, in effect, gelded the 1948 text--eliminating 31 of the 72 poems, and editing another 29. Until now, only the revised 1961 edition, called Cadastre, has been translated. The revised text lacks the radical originality of Soleil cou coupe. This Wesleyan edition presents all the original poems en face with the new English translations. Includes an introduction by A. James Arnold and notes by Clayton Eshleman.

How To Solar Power Your Home
For centuries we have used the sun's natural energy to our advantage. For example, it has been used in ancient times to provide natural lighting in temples, for photosynthesis and natural heating for growing crops, to desalinize and purify water, and it has been magnified and intensified to heat thermal power plants.
So, how can solar power be used on a smaller scale at home as clean source of energy?
Basically, there are four main ways how to solar power your home:
Passive Solar Design:
To think that Americans consume up to 50% of their energy to heat, ventilate and air-condition their homes, a large amount of money and energy could be saved by using passive solar design at home.
Passive solar design is the strategic use of the sun's energy to heat, light and ventilate your home naturally. For example, having a home that faces the sun, that has large, low-emissivity windows, and that is built from heat-retaining materials will tend to be naturally warmer in winter.
And like the Romans used the sun to light up their temples, careful placing of windows and mirrors in our homes can increase natural lighting, helping us reduce the need for electric lighting.
A natural air conditioning solution would be to plant deciduous trees on the sun-facing side of your home. This would provide cool shade in summer, but allow warm sunlight though in winter.
A solar chimney can be installed for ventilation, where the air in the chimney is heated by the sun and rises, causing fresh, cool air to rush in through the home and up the chimney.
Solar Cooking:
Solar cooking is the cleanest and cheapest way to prepare food. Although it is widely used in third world African countries, where fuel and electricity is not readily available, there is no reason we cannot use it during summer at home.
A solar cooker is made from a series of reflective panels in a parabolic shape that focus the sunlight on a box or pot, in which the food is cooked. It usually caters for up to five people, and can make a variety of boiled, roasted and baked dishes.
The one drawback of solar cooking is that it tends to take three to four times longer to cook food in. But if you weigh that against the unlimited power savings and its portability, having a little patience is not that bigger deal.
Solar Water Heating:
Solar water heating has a number of uses, and thanks to technological developments, modern solar water heating systems can be used at home to completely replace conventional boilers or geysers.
As cold water is pumped through a solar collector, the pipes absorb the sun's energy, and heat the water, which is then stored in an insulated tank for later use. Usually the water can get so hot that it has to be mixed with cold water before it can be used.
Solar Electric Power:
Also known as photovoltaic power, many homes are starting to make their own power at home with solar electric panels. These panels are made up of small silicon cells and need to be directly aimed at the sun to be most effective.
As the sun's rays penetrate the solar panels, electrons in the cells become charged, creating a current that is stored in deep-cycle batteries. When electricity is needed, the stored power is passed through an inverter to change the DC to AC, which can then be used to power various household appliances or connected to the grid for net metering.
Other than providing you cheap, clean renewable power, solar electric panels have become affordable and simple enough for anyone to install at home. In fact, with the right information it is possible to make your own solar power for under $200, as compared to getting a professional installation for a couple of thousand dollars.
With these four ways on how to solar power your home, there is no need for you to rely on the utility companies or the government for heating and lighting at home. Right now it is very possible for us to use solar power at home. It is just a matter of everyone having the determination, energy consciousness and environmental awareness to take action and harness the sun's free, natural power.
