Make a free electricity - simple homemade generator

click fraud protection
Many electricians beginners interested in one very popular question - how to make electricity free of charge and at the same time autonomous.Very often, for example, when leaving the country, a catastrophic shortage of outlets for recharging your phone or turn on the lamp.In this case, you will homemade thermoelectric module based on the collected Peltier element.With the help of such a device can generate a current, voltage to 5 volts, which would be enough to charge and connect the lamp devaysa.Then we'll show you how to make a thermoelectric generator with your own hands, providing a simple master class in pictures and video examples!

briefly the principle of action

To further you understand what is needed or that spare parts atassembling improvised thermoelectric generator, first talk about the structure of the Peltier element and how it works.This module consists of a series-connected thermocouples located between the ceramic plates, as shown in the picture below.

When a chain runs through the electric current occurs so-called Peltier effect - one side of the module is heated, and the second - cooled.Why do we need?Quite simply, if you act in the reverse order: one side of the plate to heat and cool the second, respectively, can generate a small electric voltage and amperage.We hope that at this stage it is clear, therefore, turn to the master classes, which will clearly show in what and how to make a thermoelectric generator with your own hands.

Workshop assembly

So, we have found on the internet is very detailed and at the same time simple instructions for assembling a homemade generator power based on the furnace and Peltier element.To get started, you need to prepare the following materials:

  • Peltier element itself directly with the parameters: maximum current of 10 A, voltage 15 V, size 40 * 40 * 3.4 mm.Marking - TEC 1-12710.
  • PSU from the computer (with his body only needs).
  • voltage regulator with the following specifications: Input Voltage 1-5 Volt output - 5V.In this manual, on the thermoelectric generator assembly of a module and a USB output that simplify the process of charging a modern phone or tablet.
  • radiator.You can take from the processor directly to the cooler, as shown in the photo.
  • Thermal Grease.

starting materials Radiator with a cooler photo

prepare all the materials you can proceed to the manufacture of the device by hand.So, to help you understand how to make the generator, provide step by step wizard-class picture and detailed explanation:

  1. Disassemble the old power supply and leave the body only.It will be used as a place of ignition of fire (the so-called furnace).
  2. To smooth the surface of the radiator plate Peltier glue on the thermal grease.Gluing should be labeled to the radiator, it will be the cold side.If you reverse the polarity, in the future we will need to change the polarity of the wires to the thermoelectric generator to work correctly.The first assembly step
  3. to the back side of the module housing glue supply unit, as shown in the photo below.
  4. the conclusion solder plate stabilizer with USB output.By the way, for the connection and soldering can be done by hand.Next stage
  5. Carefully place the 5-volt transformer in the radiator and proceed to test homemade thermoelectric generator.work Summary clarification

thermoelectric generator works as follows: go to sleep inside the furnace firewood, burn them, and wait a few minutes until one of the sides of the plate is heated.To charge your phone you need to make a difference in temperature between the different parties was about 100 ° C.If the cooling part (heat sink) to be heated, it is necessary to cool all possible methods - carefully pour water, put on him a cup of ice, etc.


And here is the video, which clearly shows how the self-made electric wood-burning:

can also be installed on the coldside of the fan from the computer as shown in the second embodiment, homemade thermoelectric generator with Peltier element: The homemade device with a cooling system

in this case the cooler will spend a small fraction of the power generating set, but in the end the system will be higher efficiencies.In addition to the telephone charging Peltier module can be used as power source for LEDs that are not less useful version of the application generator.Incidentally, the second version of a thermoelectric generator with a homemade appearance and design is a bit like.The only modernization, in addition to the cooling system, is the ability to adjust the height of the so-called burner.To do this, the author uses the element "body» CD-ROM (in one of the photos can be clearly seen as the most can be made structure).

If you make a thermoelectric generator with their hands on such a procedure, the output you can have up to 8 Volt voltage, so to charge the phone, do not forget to connect the converter, which will leave only the output 5V

Welland the latest version of a home-made source of electricity for the house can be represented such a scheme: item - the two aluminum "brick" copper pipe (water-cooling) and the hotplate.As a result - an effective generator that allows to make free electricity at home!Generator from scrap materials

original idea - hot water as a heat source

Here we provide three simple options homemade device that can be assembled from improvised.Now you know how to make a thermoelectric generator with his own hands, on which the principle of operation of the Peltier element and what it can be used!
