Abstract: This is the time of searching alternative energy sources because of increasing demand of energy day by day against our limited resources. Now-a-days finding and developing alternative energy sources is the important responsibility and duty for human being and it is also demand of time. However, it is not easy to find an efficient alternative energy source. Thus, we can concentrate in finding a solution which can ensure a reduced load on the conventional energy sources. This project is about an underground room heating and cooling system which takes a very little energy to run itself. The system is totally environment friendly, does not produce any harmful exhaust or gases which could pollute the atmosphere. Moreover, it can be highly economical so that everyone can install this at their houses and also in educational organizations and offices. Four types of pipes of different materials were installed underground to cause heat transfer between ambient air passed through the pipes and the soil in contact with the pipe. Heating and cooling action in winter and summer respectively can be achieved by this system. The length of the pipes used is 30 feet and dug 8 feet deep. An inlet air flow at 4.5 m/s was provided. The air flow rate was found to be reduced at the exit and a change in temperature was also found. The cooling rates varied depending upon the temperature of the inlet air.

Abstract: Energy problem is a global issue that has a serious effect on many countries in the world. The demand for energy is currently growing far greater than the supply of the nationally generated energy. In order to overcome energy crisis and the output pollution of the generation, it is suggested to use the Microbial Fuel Cell (M.F.C). M.F.Cs are devices that use bacteria as a catalyst to oxidize organic and inorganic matters and generate electric current. With the modifications that are suggested by this study, there will be clean, available and suitable energy source. Besides having the property of being efficient, eco-friendly and cheaper than the other resources, it can utilize the sewage to generate electricity and produce clean water, which mean cleaner environment with a great supply of energy and clean drinkable water. Facing challenges that affect the development of the M.F.Cs is an important aspect to be studied, so our study suggests solutions nearly for all the challenges facing them like the types of the electrodes, output pollutants, the catalyst in the cathode chamber and the real application.
