The Earth and the Moon, Revised Edition (The Solar System)
Earth belongs to a group of small, inner solar-system planets, including Mercury, Venus, and Mars, which all consist of a mantle made of silica-based minerals above an iron-rich core and crusts that show evidence of meteorite bombardment and volcanic lava flow. Beyond these basic similarities, and despite their similar formation processes in the inner solar system, these four planets are strangely different from one another.
In the very near future energy-efficient building will cease to be the exception but will be the rule. Whether insulating glazing, multifunctional facades or organic solar cells, there have been important new developments in the areas of solar thermal technology, photovoltaics, heating and ventilation technology which can make a significant contribution to the conservation of natural resources in sustainable building. They are suitable for a wide range of uses from largescale urban-planning projects, to individual single family houses.
Asteroids, Meteorites, and Comets, Revised Edition (The Solar System)
In the 19th century when asteroids were first discovered, the continuum of sizes in the solar system was not understood, because many people thought of the solar system as a Sun orbited by nine planets. However, as observers' abilities to see smaller and smaller bodies in the solar system improves because of better instrumentation,
Along with geothermal energy, solar energy is now one of the least environmentally disruptive sources of power by which electricity is generated today. Sunlight is a free, unlimited resource that hits the Earth with more energy in an hour than the people of the world use in a year. In Solar Power, readers will discover how scientists are trying to harness this power and explore potential developments into the future.
