We know that world suffers from dumbs of human's actions. Nature changes itself and speices of organisms is shrinking fast. So humanity needs alternative energy that will be much better than energy getting with traditional way. People found and created lots of ways to avoid using if oil or coal but the main problem is it's price. Therefore my goal become to be an equipment that will be effective, harmless and cheap.
Objective: Investigationf of physic-chemical properties of the school site soil. Creation of an illuminant based on Peltier element.
Hypothesis: Applying Peltier element and Seeback effect ( occurance of the phenomenon of EMF at different temperatures of air and soil) to create an environmentally sound lightning fixture.
Stages of research:
Literature review and analysis;
Researching of an information about Seeback effect. Researchinf an information about Peltier element;
Investigation of soil properties as refrigerant in the system;
Description of the physical properties of aluminum: low density, high thermal conductivity and electric conductivity, high ductility and good corrosion resistance, low temperature absorption from the soil;
Making a drawing of the fixture. Creating a business plan. Displaing the estimated return on investment and efficiency;
The analysis of the collected material, synthesis.

Experimental Procedure:
1) Determination of the type of soil using a wet process;
2) Determination of pH of aqueous extract;
3) Qualitative analysis of aqueous extract (determination of soluble compounds)
4) Measurement of the voltage, obtained from the soil;

The novelty of the research and the degree of independence: City needs a cheap generator, which will be environmentally friendly. Created electrogenerator based on the Peltier element uses ground power and air and is an alternative to traditional power generators.
Results and conclusions:
1) The investigation and analysis of the physico-chemical properties of the soil from the school site;
2) Received power from the top layers of soil between two metal plates (aluminum and copper);
3) Created a lighting fixture based on the Peltier element.
Using atmosphere air as a sun heat conductor and ground as a cooling component, there is a difference of thermal energy, which converts into electricity. With a temperature difference can be get the required amount of electric power to make LED light.

Areas of practical application: the results will be used as a further exploration of alternative energy in Atyrau as an application for lightning inaccessible areas. The cheapness of the fixture makes it available in the national economy.
Now I created the flashlight that contains from 2 LEDs and consists from only two cheap transformers. We need only temperature difference = 25 degrees per Celcium to make it light. If count everything we will get the flashlight that costs ~ 30 dollars. I think it is good result
