One important factor that makes the variations of electric current produced from solar cells (Ipv) is the variability of the weather conditions of the day. The one year experiment from January to December 2012 had been set up. The experiment of the comparison of the weather data satellite images and the different current (Ipv_d) was obtained from daily Ipv. The results illustrated that there were 4 major types of the relationship between the Ipv_d and weather conditions; 1) Low Ipv_d at around 2000 mA with low perturbations would correspond to the clear sky condition. 2) Perturbation of Ipv_d in some periods would correspond to the cloudy condition. 3) High perturbations of Ipv_d for all day long would relate to the rainy – cloudy condition. 4) High Ipv_d at around 4000 mA with low perturbations would relate to the cloudy condition all day long.

Honey-nanofibers were fabricated by electrospinning technique in order to study their potentiality for biomedical application especially as wound healing materials. Honey/Gelatin ratios operating voltages and solution flow rates were considered as the experimental variables. All synthesized nanofibers were tested for their sizes percentages of water uptake and contact angles between the fiber surfaces and water droplets. It was found that 1) size of nanofibers and contact angle between the fiber surfaces and water droplet increased with increasing of honey in solution 2) size and percentage of water uptake of nanofibers increased with stepping up of operating voltage and 3) size of nanofibers was minimized at the flow rate of 0.06 ml/hr for each operating voltage of this study.

This research was to study the feasibility of CIGS for condominiums in Thailand by studying the energy consumption of building which divide by behavior of users which interested in day time users and night time users. Then study approach and feasibility to apply CIGS for condominiums by consider energy consumption and economic efficiency of installation CIGS for energy conservation. The result showed that when installed 110 watts/m2 of CIGSs on windows in a room type can be provide electricity 2.51 kWh per day 2.81 kWh per day and 3.75 kWh per day which can be represented 40 percent of the total energy consumption. In other word can be reduce energy supply from grid per month 75.30 kWh 84.3 kWh and 112.50 kWh. While investment cost per square meter of CIGS is about 23000 - 35000 baht which equivalent to 3 percent of total condominium price that mean payback period is about 8 years. Although CIGS is not able to provide all of electric consumption in building but from the assessment of economics found that there is a very interesting to investment it should be interested policy for the government to enforce condominium to install CIGS for sustainable development.

During the daytime solar cells can be used in terms of meteorology because the variations of the current obtained from solar cells are associated with changes in daily climate. The case study of the comparison between the surface temperature and the different current (Ipv_d) obtained from the solar cells in the periods of November 2011 to February 2012 which known as the winter period of Thailand had been conducted. The result showed that it was possible to observe the decreased surface temperature at the time that the increased Ipv_d was more than 6000 mA. Vice versa the decreased surface temperature would not be observed when the Ipv_d was below 6000 mA. The decreased surface temperature may reflect the influence of the traveling high pressure area moving to cover and collide with the steady-low pressure area at the study area. The result of the collision caused extensive cloud cover resulting in increasing Ipv_d.

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 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 220 AC notgood but 12 DC good and use inverter to 220 v.
