Windmill making is very easy. \n\nTake a small fan like structure. The fan should be connected to a vertical poll. The fan spin should be connected to a cycle dynamo. This can be done using a hard rubber band. (Something similar to the rice mill). The dynamo inturn can connect to a light. \n\nBut if you have a prejudice that a small windmill can produce enough electricity to light up your house, it is wrong. Windpower is one of the less efficient power sources. \nWindpower < Hydro electric power < Coal power < Diesel power < Nuclear power.

There are many ways to take advantage of the energy produced by the sun.  A good place to start is with a passive solar energy water heater.  They are inexpensive to install and easy to maintain.  The simplest ones use the radiant energy of the sun and convert that to thermal energy using a material that absorbs the light instead of reflecting it, in layman's terms, something black.  \n\nPhotovoltaic (solar cell) systems convert sunlight directly into electricity. A solar or Photovoltaic cell consists of semiconducting material that absorbs the sunlight. The solar energy knocks electrons loose from their atoms in a semiconductor, allowing the electrons to flow through the material to produce electricity.\n\nFor a more in-depth explanation of photovoltaic technology try this site.

(m)\n\nMake a solar cell in your kitchen\n\nWe found this article on http://www.scitoys.com/scitoys/scitoys/echem/echem2.html \n\nIt was super, super, super cool, so we thank them for allowing us to post it at TheSolarPlan.com!  This is nifty!\n\nA solar cell is a device for converting energy from the sun into electricity. The high-efficiency solar cells you can buy at Radio Shack and other stores are made from highly processed silicon, and require huge factories, high temperatures, vacuum equipment, and lots of money. \n\nIf we are willing to sacrifice efficiency for the ability to make our own solar cells in the kitchen out of materials from the neighborhood hardware store, we can demonstrate a working solar cell in about an hour. \n \nOur solar cell is made from cuprous oxide instead of silicon. Cuprous oxide is one of the first materials known to display the photoelectric effect, in which light causes electricity to flow in a material. \n\nThinking about how to explain the photoelectric effect is what led Albert Einstein to the Nobel prize for physics, and to the theory of relativity.\n\nMaterials you will need \n\nThe solar cell is made from these materials: \nA sheet of copper flashing from the hardware store. This normally costs about $5.00 per square foot. We will need about half a square foot. \nTwo alligator clip leads. \nA sensitive micro-ammeter that can read currents between 10 and 50 microamperes. Radio Shack sells small LCD multimeters that will do, but I used a small surplus meter with a needle. \nAn electric stove. My kitchen stove is gas, so I bought a small one-burner electric hotplate for about $25. The little 700 watt burners probably won't work -- mine is 1100 watts, so the burner gets red hot. \nA large clear plastic bottle off of which you can cut the top. I used a 2 liter spring water bottle. A large mouth glass jar will also work. \nTable salt. We will want a couple tablespoons of salt. \nTap water. \nSand paper or a wire brush on an electric drill. \nSheet metal shears for cutting the copper sheet. \n\n\n\n\n\n\nHow to build the solar cell \n\nMy burner looks like this: \n\nThe first step is to cut a piece of the copper sheeting that is about the size of the burner on the stove. Wash your hands so they don't have any grease or oil on them. Then wash the copper sheet with soap or cleanser to get any oil or grease off of it. Use the sandpaper or wire brush to thoroughly clean the copper sheeting, so that any sulphide or other light corrosion is removed. \n\nNext, place the cleaned and dried copper sheet on the burner and turn the burner to its highest setting. \n\nAs the copper starts to heat up, you will see beautiful oxidation patterns begin to form. Oranges, purples, and reds will cover the copper. \n\n\nAs the copper gets hotter, the colors are replaced with a black coating of cupric oxide. This is not the oxide we want, but it will flake off later, showing the reds, oranges, pinks, and purples of the cuprous oxide layer underneath. \n\n\n\nThe last bits of color disappear as the burner starts to glow red. \n\nWhen the burner is glowing red-hot, the sheet of copper will be coated with a black cupric oxide coat. Let it cook for a half an hour, so the black coating will be thick. This is important, since a thick coating will flake off nicely, while a thin coat will stay stuck to the copper. \n\n\nAfter the half hour of cooking, turn off the burner. Leave the hot copper on the burner to cool slowly. If you cool it too quickly, the black oxide will stay stuck to the copper. \n\nAs the copper cools, it shrinks. The black cupric oxide also shrinks. But they shrink at different rates, which makes the black cupric oxide flake off. \n\n\nThe little black flakes pop off the copper with enough force to make them fly a few inches. This means a little more cleaning effort around the stove, but it is fun to watch. \n\n\nWhen the copper has cooled to room temperature (this takes about 20 minutes), most of

You can use solar energy to evaporate water anywhere where you  can keep water in liquid state. Rather than constructing a steam engine, why not build stirling motors using any available gas, and avoid the narrow climate range? As with the steam engine, the Stirling would require a station in the cycle where the gas is heated and one where the heat of the gas is transferred to a colder reservoir.\n\nIn both cases you get mechanical energy which then can be transformed into whatever energy you might need. For getting electricity, direct transformation of sunlight into electricity in solar cells might be a more effective way.

there are 2 ways:\n1. using a thermocouple u will generate a potential difference. but the thermocouple will not generate much current so the power will be small.\n2. this is a classical method. a steamengine coupled to a dynamo.

Steam generators produce steam not condensation.  A steam generator (e.g., in a nuclear plant) generates steam that can be used to drive a steam turbine to generate mechanical or electric power.  The oldest systems (non-nuclear) discharged the steam wastefully to atmosphere.  In modern plants, exhaust steam from a steam turbine is directed to a steam condenser (where cooling water is used to condense the steam).  This allows the condensed water that must be highly pure and chemically treated to be reused by pumping it back to the steam generator.  More importantly, because the steam condenser reduces the turbine exhaust pressure well below atmospheric pressure, the steam is permitted to expand even more through the turbine blades extracting more power from the steam.  This greatly improves overall system efficiency by providing far more power from the energy expended to produce the steam.

A generator is a machine that converts mechanical power to electrical power, by making a conductor cut across a magnetic field's lines of force.  This is done by moving either the conductor or the magnetic field.  Current flows in the conductor if its ends are connected to an electrical load thus producing electrical power.  Because an opposing magnetic field is created by the current in the conductor, it requires mechanical energy to maintain this motion.

It is possible to get electricity from a lemon.  Yes, they are not only the common stacks that can generate electricity.  The most legal E is that in the lack of the lemon you can use an orange, or same a potato!  In the truth, the electric chain appears from the electric potentials of two metals that are cravados in the lemon, the orange and the potato.  The acid character of limão/laranja and the basic character of the potato help in the conduction of the electricity.  But what it is that cause this chain?  It thinks a little before continuing the reading!  Good, after waiting you to think a bit, we go to continue:  two metal pieces are used.  The best one resulted appears of the zinc combination and has covered, but also it can be used zinc and aluminum, or still brass and aluminum.  Some types of pregos contain zinc, and the copper can be found in the wire form and same in the composition of some currencies.  One can also be used (in the lack of these) taxinha of these of brass and one clips.  After to fincar them in the lemon (or orange, or potato) and to join them for wires, can be bound them a small electric device to it.  The best one resulted if gives using one of these electronic clocks - stack of this is taken off it and becomes it linking of wires positive and negative in the small terminals of the clock.  The produced chain is enough to light it, still that per some minutes.  It does not forget cleaning the metal parts, and preventing that before they touch themselves in the interior of the lemon (or of the orange, or still of the potato).

An electric generator is a device used to convert mechanical energy into electrical energy.\n\nThe generator is based on the principle of "electromagnetic induction" discovered in 1831 by Michael Faraday, a British scientist. Faraday discovered that if an electric conductor, like a copper wire, is moved through a magnetic field, electric current will flow (be induced) in the conductor. So the mechanical energy of the moving wire is converted into the electric energy of the current that flows in the wire.The mechanical energy needed to turn the generator comes from the brown hand crank at the front of the generator. In a hydroelectric power plant, the mechanical energy to turn the generator comes from the water turbine, which is turned by the force of falling water. The hand crank causes the red wire to spin inside a magnetic field (the blue lines). As Faraday learned, moving the wire through the magnetic field causes electric current to flow in the wire. The turning red wire is connected to a volt meter, which shows the amount of electric current that is produced. In a hydroelectric plant, the generator is connected to transmission lines that deliver the electricity to your home or business.\n\nThe controls allow you to control the speed and direction of the generator and turn portions on and off for greater clarity. You can also use the radio buttons to show a direct current, or DC generator (with commutator) or an alternating current, or AC generator (without commutator).

Hmm...  If I remember the physics right, it goes like this: Take two parts hydrogen and one part oxygen and mix them in a chamber with a catalyst and a proton exchange membrane and you get water and electricity.
