What is the force behind the existence of life? Who controls the earth’s climate? What is the factor that contributes to the greenery around us? Solar energy or the light and heat radiations from the sun is the driving power behind these life processes.
Turning the energy from the sun into a benefit for the homeowner is a fairly simple task for people who wish to take advantage of homemade solar energy. Black plastic hoses coiled in the heat of the day will heat the water inside to a temperature that will be more than needed to shower or warm a pool.
Making a box lined with aluminum foil will create an effective but slow grill or broiler for the barbecue as well. Not a great need for technological skill here, but try this in summer and amaze the neighbors!

Renewable Energy Technologies
The Mauritius government program of promoting the increased utilization of renewable energy sources like solar power and biomass was driven in part by the constant rise of petrol prices over the past few years. Also, government revenue that can be saved from reduced dependence on imported petrol could be put to better use in improving the social development programs in Mauritius. As opposed to just using the said funds to allow Middle-Eastern despots to continually build-up their own military might. Contributing further to the instability in the region.
Electricity is produced by electromagenetic induction, and that is by causing the turbines to roate. Why can’t it be possible to harness and store electricity from the billions of wheels rotating such as of vehicle wheels and inumerous machineries all arround us for our use using a suitable device.
The sun is shining, and the only cloud in the sky is the latest utility bill that seems to rise every month…
The answer may be that you need to seriously examine how to build your own solar panels, and here are a few tips that just might help…
Check out the online specials for materials and save on the construction cost. In addition, there are many suppliers who will offer everything that is required to complete the job, as well as plans and advice on assembly.
The tools needed to build your own solar panels will probably already be found in the workshop and include hammer, saw, soldering iron, screw drivers and a knife.
The materials list is a little longer but most people already have some timber to make the frame for mounting the panels on the roof and the screws and wood panels to make the housing for the cells. Read more on Build Your Own Solar Panels…
Small wind generators are not just projects for enthusiasts, but are a true possibility for the average home owner to generate energy to meet their demands and to sell a little extra back to the utility company.
Understanding how to build a wind turbine is relatively simple. The alternatives range from purchasing a kit set that simply needs assembling, to starting from day 1 and building the tower, generator and even carving the windmill blade from suitable wood.
Before you begin to select which kind of construction you need, a little investigation into the wind flow potential for the site may be beneficial. Wind flow atlas details can be found online, and you can also monitor the prevailing winds utilizing a small wind flow meter over a period of months. This will give you all the details needed to decide where a windmill might be located.
can anyone tell me some information about solar sails?
m..are solar sails in use today?how are photons used as a fuel?can you name any probes that are sent using this method?
Soviet union tried to solar sail experiments from Mir space station
But due to some problem, they were not successful.Sunlight gives some radiation pressure so it is possible to have them for inter planetary travel.
Anywhere the Sun’s rays can reach, solar thermal power can be generated. The Sun will last for another 5 billion years so the energy it provides will far outlast humanity and it’s ability to harness that energy.
The Sun is a free source of energy, and better technology makes it easier to convert sunlight into electricity and harness the Sun’s heat more efficiently, making it easier to supplement the electricity or hot water used by a household. Photovoltaic cells, which convert sunlight into electricity, are becoming increasingly efficient and storage batteries are getting both cheaper and better at storing energy. As a result, more sophisticated solar energy systems can be set up easily. Solar thermal power systems tend to provide hot water to the home rather than producing electricity directly.
In addition to affecting farmers, turning off the tap is changing the way we generate solar electricity. Currently, solar-thermal plants generate electricity through mirrors redirecting solar energy to a boiler. The solar energy heats up liquid sodium which turns liquid water into water vapor. The steam turns a turbine, generating electricity.
The water needs to be cooled, which is achieve through evaporation. Since so much water is lost through evaporation, it must constantly be replenished. An alternative method of cooling using fans and heat exchange saves most of the water, but the procedure adds costs.
