Experimenting with Solar Energy
Using solar energy for many different things around the house and more
There are many experiments that are being carried on with solar
power. Following is a collection of
a few of these.
Solar chimneys are used to generate electricity by heating the air within the "chimney". This heated air then expands and rises to turn a turbine at the top of the "chimney" and generate electricity.
A solar pond is created when water in a pond or lake
is high in salt-content, and is fairly deep.
As the water gets deeper, it gets hotter, because of the salt in the
water. An experiment was conducted at
the Dead Sea, near Jerusalem.
They found that at the bottom of the "lake" the temperature could reach
90 degrees C and had an estimated solar-to-electric efficiency rate of
Thermoelectric devices convert a temperature difference between materials that are un-alike and turn it into an electric current. This technology has been used by the United States in deep space missions.
Space solar power systems use the idea that sunlight is "collected" in space and then beamed to earth in the form of microwave radiation, then turned into electricity and distributed from there. The scientists are hopeful that this energy can be delivered about 96% of the time.
