Uses of the Moon and Possibilities

The Earth have one natural satellite; the Moon. The moon is the closest natural celestial body seen to the naked eye from Earth. Scientists believe it has helped shaped life and climate of the planet over the eons. But is there really any use of it? If so, how can we make use of it? Let's look into some possibilities..

How Energy from the Sun Drives the Earth

The Sun produces massive amounts of energy by a process called nuclear fusion where Hydrogen atoms are combined to form Helium atoms. This energy is emitted to space in the form of electromagnetic radiation. After 8 minutes of journey, a portion of it arrives on Earth with an estimated energy density over a 1000 Watts per square meter. About 30% of this energy is reflected back to space. The rest of it powers up the planet as we know it. On Earth, energy arrives in the form of electromagnetic waves including Infra-red (IR), visible light and Ultraviolet (UV). We refer to it as “ sunlight ”. The following list is a composition of the main forms of energies produced from solar energy and stored on Earth.

Our eyes perceive light. Our brains interpret it into shapes and forms that we are familiar with. What we see is lighter or darker depending on how much of light enters the eye (that is; intensity) and is applied with "colours" based on the flavours of light we receive.
