Experiment: Water Purification by Solar Distillation and increasing efficiency of system
Every solar water distiller has a tank of polluted water covered by a clear glass or plastic, slanted or curved such that the condensed water vapors can slide down into the distilled water storage.
Procedure:In this design a sheet of glass will be used. This clear cover is installed in an angle to force condensed water to move to one side where it will be collected.
As sunlight warms the black bottom and sunlight is reflected by mirror which is back of system ,then heat is transferred to the water,the top of the water evaporates on to the inside of the glass cover, which is tilted toward the fresh water drain..
Increasing System Efficiency
We must know factors effecting vapor pressure. They are amount of surface area - the greater the surface area exposed to the surroundings the faster it will evaporate. Poor some water on the floor and put the same amount in a cup or a bowl, the water on the floor will evaporate much faster. But in our system surface area is constant because we will use same system.
humidity - this has to do with vapor pressure. if the air is extremely humid there will already be a lot of water vapor in the air, not allowing as much of the water to evaporate.Because of this factor we try to decrease humidity in our container by using fans and cooling cover down.
Temperature of the surrounding - this one is simple, put some water in a cold environment and some water in a warm environment and obviously the warm one will evaporate faster. There is more energy in warm air.For our system it depends on weather of day
Temperature of the liquid - Same as above.For this case if we use less amount of water ,system will warm up shortly.So it will help us about time.
Wind speed - more wind blowing across the surface of the liquid means there will be constantly air with no water vapor in it right above the liquid, resulting in a faster evaporation. This is why putting a fan on a wet carpet or something of that sort will dry it out faster.For this situation we use fan of solar cell.

How is passive and active solar heating systems different from one another?
a passive solar system converts sunlight into thermal energy without using pumps or fans and active solar system captures the suns energy then uses fans and pumps to distribute the heat
What is solar heaters useful for?
Solar heaters are useful for heating water with natural energy, thus saving electricity. The question is can effective solar heaters be made for less cost than using the electricity.
What is one of the ways in which people can implement sustainable development?
building power plants using sources of renewable energy such as wind or solar power
What benefits would a solar power system provide?
One benefit of a solar power system is that it is clean energy. Using the power of the sun to create electricity does not produce any pollution. Another benefit of solar power systems is the savings on the electricity bill.
How can you help lessen the energy crisis in your country?
(1) By using less energy. For example, turn off lightbulbs you don't use, use energy-saving lightbulbs, try to walk or use public transportation instead of using a private car whenever possible. (2) By using alternative energy sources. For example, install a solar hot water system - that will save traditional energy when taking a shower.
What energy do you get from the solar system?
That depends on what you are using to capture energy, if you are using solar panels to get it, then you are converting solar energy into electrical energy.
What energy occurs when using a solar oven?
solar energy
Is any one using solar energy?
We all are using solar energy directly or indirectly. Using solar energy doesn't only means using solar cell or solar heaters etc... but food is also a byproduct of sunlight, when we dry our clothes and grains insunlight it also a use of solar energy.
What country gets the most solar energy?
many country using solar energy like USA etc plz tell me the history of solar energy many country using solar energy like USA etc plz tell me the history of solar energy
How solar energy is used to run cars?
By using solar energy to charge the batteries
What are some pros and cons of using solar energy?
One will find using solar energy has it's own set of pros and cons. Since using solar energy doesn't produce pollution, it can help improve the environment of the earth. However, a con of using solar energy would be the production of the solar energy collecting devices, which do produce quite a bit of pollution.
What type of energy is solar energy converted to?
Solar Energy is typically converted into electricity and stored using a battery. There are other ways of using solar power but this is the most typical format
How can we trap solar energy?
by using solar photovoltaic (SPV) cells which traps solar energy and then converts it into electricity.
What is the impact of people using solar energy?
Solar energy is a renewable energy source, using it, we release less co2 into the atmosphere, thus stopping global warming. (solar powe is good)
How is solar energy recovered?
Solar energy is recovered by using solar panels. The solar cells on the solar panels use the energy from the sun to produce the electricity used for everyday life.
How do various technologies or practices influence the use of solar energy?
Solar energy influences technologies to use solar panels to conserve energy by using solar panels.
What the benefits of using solar energy?
Once the equipment has been paid for, solar energy is free.
