In my project we are going to produce electrical energy with the help of compressed air. Generally we use air compressors which are operated using motor to compress the air, but here we are using pistons to compress the air and then the compressed air will be stored in a CAES (Compressed Air Energy Storage). The storage system of a CAES is one of the most interesting characteristics of this technology, and it is strictly related to its economic feasibility, energy density and flexibility. We will take the storage depending upon the setup and area on which we are setting it up. We are going to use pistons with the speed breakers. These pistons will help us compress the air and then air will be stored into the storage. When any vehicle passes over the speed breaker an air piston will compress the air and store it. Here we will get compressed air and now we can use this compressed air to move a turbine. Now, the compressed air will be passed to the turbine with high pressure and then the turbine's fins will start moving and electricity will be produced. We can also use another way to compress the air and then store it in the air energy storage.
