This research aimed to study powe generation from heat loss strove by thermoelectric generator unit. As cooking with a gas stove can cause heat loss between the stove and the cookware this heat loss from gas stove can be converted into the electricity. For the experiment the researcher used a gas stove model KB5 installed with thermoelectric plate model TEG1-241-1.4-1.2 connected in a series to the power of 4 modules. Then experimental conditions of the gas pressure in the gas strove were set at 0.1 0.2 0.3 0.4 0.5 and 0.6 kg/cm2 respectively while the amount of mixed air was constant during the experiment. The results showed that when the gas pressure was at 0.6 kg2 the temperatures of the hot side and cold side of the thermoelectric generator was equal 250.5oC and 65.5oC respectively. Lt also generated the highest electric power of 53.3 watts. The power conversion efficiency was 5.3% at 38.1 Volts with 1.4 Amperes. In addition when electric was connected to a thermoelectric generator unit with 12 VDC 7-watt LED bulb the gas pressure in the gas stove were set at 0.3 0.4 0.5 and 0.6 kg/cm2 respectively was affected by the difference between the heating temperature and the cold temperature in the range of 185o C that could lighten up LED bulb.

This project aims to create a series of demonstration power plant water. And the operation of the circuit Inverter split by the end of demonstration runs as follows. Theory and documents relating to the source of electrical power water power the working principle of the circuit. Inverter the principle of integrated battery charger main circuit voltage VDC LED LED SMD (Surface-Mounted-Device) a voltmeter. Ammeters digital LCD display couples. Make plans to offer advisors the project approved. Design demonstration kit Equipment supply and assembly Assembly and demonstration the production of electricity from hydropower 220 VAC test run is a series of demonstrations to generate electricity from water power to 220 VAC storage performance voltage and current output. And analyze the results of the operation of the demonstration production of electricity from hydropower 220 VAC and conclusions in this chapter are the results of the experiment demonstrated the production of electricity from hydropower and the conclusion of the trial in order to be used. effectiveness of the objectives of the experimental procedure the results can not load a load test. Test kits demonstration power plant and the demonstration set to produce 220 volts for 25 minutes at a constant voltage. The electricity does not increase or decrease. Always works The term of office is fixed or reduced by the ratio of active power increases.

This research project presents about wind turbine simulation for connected single phase grid system using hysteresis current control technique to generate PWM signals for controlling a single-phase voltage source inverter. The simulation system presented here uses the program. MATLAB/Simulink in the simulation of the wind turbine connected to the shaft of a three-phase permanent magnet generator is produced by alternating current through the full bridge rectifier circuit. Then the power supply is applied to the single-phase inverter circuit which is connected to the single-phase autotransformer to power transfer to the single-phase grid system. The simulation results confirm the validity of the proposed system with satisfaction under various conditions.

Research this project invents for design and build the water turbine produce the electricity by set up the equipment produces the electric current from water energy flows from the nature which be new choice for Thailand in using energy pays back. then born the idea in energy water lead flows in the tide comes to use is born the advantage The water turbine has produced the electricity that does designing and establish to compose 3 part importance be the part of water buoy water turbine part is the pin wheel that is made of the iron I each have a draught 30-40 centimeter group part carries round which compose the gearwheel yes carry round and a transmitting belt carry round . From pin wheel test produces the electric current that establishes to induce float in a river already record seek feeling numb fire effiCiency reaches to open the stump makes straight for to share 5 the ampere water speed flows to share 12 the meter / minute I the speed round the pin wheel turns to share 4 rpm. and tend that increase follow the speed of the water that increases.
