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 90 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 12 DC good and use inverter to 220 v. AC

The purposes of this research are to study water and electricity consumption behavior of the students to study understanding of water and electricity saving and to compare the difference of water and electricity consumption behavior classified as personal characteristic of the students Faculty of Home Economics Technology Rajamangala University of Technology Phra Nakhon. This research was descriptive research. The sample group used in the research was the students Faculty of Home Economics Technology Rajamangala University of Technology Phra Nakhon. Size of the sample group was specified to be 325 people by stratified sampling. The tool used in data analysis was questionnaire divided into 3 parts including part 1: questions regarding general details of a respondent part 2: questions regarding knowledge of water and electricity saving consumption the students of Faculty of Home Economics Technology Rajamangala University of Technology Phra Nakhon and part 3: questions regarding water and electricity consumption behavior of the students Faculty of Home Economics Technology Rajamangala University of Technology Phra Nakhon. The statistics used in data analysis consisted of frequency percentage mean standard deviation and hypothesis testing using t-test and ANOVA (Analysis of Variance) for testing parallel difference by LSD method. The research result found that: 1. The level of water and electricity consumption behavior of the students Faculty of Home Economics Technology Rajamangala University of Technology Phra Nakhon was overall in the moderate level. 2. The level of understanding and knowledge regarding water and electricity saving of the students Faculty of Home Economics Technology Rajamangala University of Technology Phra Nakhon was overall in the moderate level. 3. The comparison of different behavior of water and electricity consumption specified according to personal characteristics could be summarized that the students having different gender class and major had identical water consumption behavior and the students having different gender class and major had identical electricity consumption behavior. On the other hand the students having different major had statistical significance in electricity consumption behavior at 0.05

This research presents the development of a low rate and low power consumption low rate wireless network. Low rate wireless networks are cheap and comprised of a small fully autonomous processing communication and remote control devices. The purpose of this study is to develop the system for remote wireless lighting system. They will work with wireless network system (WNS). WNS has been restricted power supply communication distance and low computing power. But they will work with network in vast area send and receive raw data from each network node. It has the ability to cooperatively collect data and retransmit in order to process or alert. The step of the experiment is creating main node and sub node in lighting area and transmission of control data between them with less electrical wiring. When wireless node not receiving or transmitting data the module can be switched into the sleep mode low power consumption mode. We can reduce the use of electrical wiring; insulated insulation material or other that related to and include energy too.
