Space-based solar power (SBSP) is the concept of collecting solar power in space for use on Earth. It has been in research since the early 1970s. SSPS consists of a space-based power generation/transmission facility that gathers sunlight‚ converts it into microwaves or laser beams‚ and transmits those to the ground; and a power receiving facility on the ground. Space-based solar power essentially consists of three elements: • a means of collecting solar power in space‚ for example via solar cells or

energy. Introducing the Solar Bottle Bulb -- an alternative source of daylight powered by the sun. It is made from an old soda bottle. By filling it with water and sealing it into the roof‚ the water refracts the sun’s rays and provides about 55 watts of light to a darkened room. This was invented in 2006 by students at the Massachusetts Institute of Technology (MIT). It can be built and installed in less than 1 hour‚ and uses inexpensive or recycled materials. The water is mixed with some bleach

Isaac Solar Ice Maker Solar Icemaker Up to 1000 pounds of ice per day! Low cost and reliable source of ice for situations requiring 25 to 1000 pounds of ice per day (12-450kg). "Isaac" is the acronym for Intermittent Solar Ammonia Absorption Cycle. Ammonia absorption refrigeration technology was developed in the 19th century and is still used in industrial applications. Energy Concepts has adopted this technology to a machine which uses the sun as the only energy output. The particular advances

to Congress‚ 2/24/09) Solar energy is the cleanest‚ most abundant‚ renewable energy source available which described as the sun’s rays that reach the earth and can then be converted into either thermal (heat) or electricity. Solar energy converted into heat can be used to: heat water for use in homes and buildings and heat spaces. Solar energy can be converted into electricity in two ways: 1) photovoltaic cells; and 2) solar thermal plants (also known as concentrated solar power or CSP)‚ which are

Harnessing of Solar Energy: Photosynthesis versus Semiconductor Based Solar Cell Photosynthesis and semiconductor-based solar cells are both used to harness solar energy from the sun – photosynthesis for plants and semiconductor based solar cells for human beings. Photosynthesis consists of light reactions and dark reactions. It is a process in which carbon dioxide (CO2)‚ water (H2O) and light energy are utilized to synthesize an energy-rich carbohydrate like glucose (C6H12O6) and to produce

But this too is not available in pure time. There are several reasons for this. Untreated industrial wastes discharge is polluting our water system. Similarly‚ agricultural pesticides and insecticides are polluting our underground water. Impure water leads to an increase in gastrointestinal diseases. Another factor is of waste matter from daily

SOLAR ENERGY PRODUCTION IN INDIA Coming specifically to the land of much sun‚ heat and humidity as well as persistent power shortages‚ overdependence on coal (52%) and huge oil and gas imports‚ solar energy production in India remains appallingly low. This is made evident by the minimal range of solar energy products in India. Solar lighting (solar lamps‚ street lights)‚ rural electrification‚ solar water heaters‚ solar cookers and PV pumps sum up the measly range of solar energy products

hydrogen is rarely found alone in nature. It is usually bonded with other elements. For more information‚ see fuel properties and the Hydrogen Analysis Resource Center. Very little hydrogen gas is present in the Earth’s atmosphere. Hydrogen is locked up in enormous quantities in water (H2 O)‚ hydrocarbons (such as methane‚ CH4 )‚ and other organic matter. Efficiently producing hydrogen from these compounds is one of the challenges of using hydrogen as a fuel. Currently‚ steam reforming of methane (natural gas) accounts for about 95% of the hydrogen produced in the United

ASTOUNDING SOLAR ENERGY FACTS What is solar energy? People often think of solar energy as solar panels mounted on roofs in sunny neighborhoods. This is only part of solar energy (“Solar energy facts‚”2012). Solar energy is the oldest energy source. Plants‚ animal and the microbial life have been using it as a principle energy source since the times of creation. It is in the form of heat and light. In the past years‚ people have tapped solar energy enabling it to be used at all times; including
