Eco Friendly India- The hottest idea for cooling: How can Solar Refrigerators minimise green house effect ?
September 28th, 2010 | 
Author: With a solar refrigerator, the parts of the refrigerator – the compressor, condenser, and other components don’t change. The only thing that changes is how the energy is supplied to the refrigerator. Instead of using an electrical system it uses solar power.
The refrigerant is replaced with ammonia or lithium bromide mixed with water. The heat of the sun is used to increase the pressure of the gas, which turns into a liquid, just like in an electric refrigerator. When the heat is removed, the liquid evaporates and lowers the temperature.
Longtime passed since I read about ‘refrigirators’ Yet with the poor memory let me try to answer u, who knows the answer.
Compounds that have boiling point less than -10*F can be used as refrigant if they have suitable other features to use in day to day life.Of them so long we are using Freon 12 in most of the cooling units.I think this spoils the environment and hence when it is replaced by ammonium/lithium bromide, the problem is getting solved, in Solar Refrigirators.

http://goodnews.ws/
Space-based solar power (SBSP) (or historically space solar power (SSP)) is a system for the collection of solar power in space, for use on Earth. SBSP differs from the usual method of solar power collection in that the solar panels used to collect the energy would reside on a satellite in orbit, often referred to as a solar power satellite (SPS), rather than on Earth’s surface. In space, collection of the Sun’s energy is unaffected by the day/night cycle, weather, seasons, or the filtering effect of Earth’s atmospheric gases. The world Radiation Centre’s 1985 standard extraterrestrial spectrum for solar irradiance is 1367 W/m2 The integrated total terrestrial solar irradiance is 950 W/m2. Therefore, extraterrestrial solar irradiance is 144% of the maximum terrestrial irradiance. A major interest in SBSP stems from the length of time the solar collection panels can be exposed to a consistently high amount of solar radiation. For most of the year, a satellite-based solar panel can collect power 24 hours per day, whereas a land-based station can collect for only 12 hours per day, yielding lower power collection rates around the sunrise and sunset hours. The collection of solar energy in space for use on Earth introduces the new problem of transmitting energy from the collection point, in space, to the place where the energy would be used, on Earth’s surface. Since wires extending from Earth’s surface to an orbiting satellite would be impractical, many SBSP designs have proposed the use of microwave beams for wireless power transmission. The collecting satellite would convert solar energy into electrical energy, which would then be used to power a microwave emitter directed at a collector on the Earth’s surface. Dynamic solar thermal power systems are also being investigated. Some problems normally associated with terrestrial solar power collection would be eliminated by such a design, such as dependence on meteorological and weather conditions, and the panels being prone to corrosion. Other problems may take their place though, such as cumulative radiation damage or micrometeoroid impacts. The SBSP concept is attractive because space has several major advantages over the Earth’s surface for the collection of solar power. There is no air in space, so the collecting surfaces would receive much more intense sunlight, unaffected by weather. In geostationary orbit, an SPS would be illuminated over 99% of the time. The SPS would be in Earth’s shadow on only a few days at the spring and fall equinoxes; and even then for a maximum of 75 minutes late at night[40] when power demands are at their lowest. This characteristic of SBSP avoids the expense of storage facilities (dams, oil storage tanks, coal dumps) necessary in many Earth-based power generation systems. Additionally, SBSP would have fewer or none of the ecological (or political) consequences of fossil fuel systems. SBSP would also be applicable on a global scale. Nuclear power especially is something many governments are reluctant to sell to developing nations, where political pressures might lead to proliferation of nuclear weapons technology. SBSP poses no known potential threat. Solar energy conversion (solar photons to DC current). Two basic methods of converting sunlight to electricity have been studied: photovoltaic (PV) conversion, and solar dynamic (SD) conversion. Most analyses of solar power satellites have focused on photovoltaic conversion (commonly known as solar cells). Photovoltaic conversion uses semiconductor cells (e.g., silicon or gallium arsenide) to directly convert photons into electrical power via a quantum mechanical mechanism. Photovoltaic cells are not perfect in practice, as material purity and processing issues during production affect performance; each has been progressively improved for some decades. Some new, thin-film approaches are less efficient (about 20% vs 35% for best in class in each case), but are much less expensive and generally lighter. In an SPS implementation, photovoltaic cells will likely be rather different from the glass-pane protected solar cell panels familiar to many from current terrestrial use, since they will be optimized for weight, and will be designed to be tolerant to the space radiation environment (it turns out that fortuitously thin film silicon solar panels are highly insensitive to ionising radiation), but will not need to be encapsulated against corrosion by the elements. They may not require the structural support required for terrestrial use, where the considerable gravity and wind loading imposes structural requirements on terrestrial implementations.

Home Portable Solar Backup Generator – Portable Solar Power Generator
If you’re worried about the rising cost of electricity or gas to maintain your home, or if you just want a back-up system in case of a power outage or civil unrest, then buying a solar generator would be the most logical thing to do. “Off-the-grid” living can not only save you money, but give you the peace of mind that comes with knowing you’re not dependent on anyone or any institution for your survival.
Before you buy a solar generator however, you should understand a few things about the system. A solar generator works by converting solar energy into electrical energy. This converted energy is then used to power lighting, heat water, and run appliances. The general consists of solar panels (which must be placed where they will receive the most possible sunlight), a deep cycle battery for continuous use, and an inverter.
Which solar generator you purchase also depends on what you plan on using it for. Are you simply going to power the refrigerator or freezer during an electrical outage or do you want to run multiple rooms with it? Buying a larger solar generator will of course cost more; smaller, more portable units will run just a few thousand dollars.
http://thesolargenerator.info offers a choice of several sizes of solar generators to fit your needs. What are you waiting for? Check out our website to see how you can harness solar power to run your home “off-the-grid”.
