Producing Electricity

The topic I choose because energy will be a big problem in the future and people will be begging for renew-able energy sources. So the idea is to decide and build a very cheaper energy source. While walking in my school corridor a thought came to me that in busy big cities almost every hour a big number of vehicles pass by so the idea was to get electricity from them so that the fuel they are burning is used for electricity generation not directly but indirectly. I now was in need for creating a lever so that I could use it to move a turbine or a motor to charge a 12 volt battery as it was to be prototype. Another Problem with the system was also that is requires a lot of space under the ground to be fitted with big and large number of shocks to lift and support the heavy weight of the traffic. The idea was roaming in my head all the time, suddenly my watch gave the beep of 10.00 am and i was shocked that the solution is in my hands all the time..................
It was the piezoelectric speaker that was in my hands all the time good thing that it contain electric coil that can be used to generate electricity by pressure now I constructed a platform of these speaker covered in the packing box's card. almost 30 of these gave me 12V after I connected the diode gate bridge and amperes were less but still I invented the method for the production of the electricity.
I will upload the method for its  production with some pics  and schematics next time don't forget to post and comment and feel free for your suggestions

Hello
This is my first post over my blog as I started it for first time and I would try my level best to provide you with information in everyday life related to almost everything but my main topic would be the Computers and mobile technology
