Introduction In today’s world, global warming continues to threaten the survival of our species and it will not stop unless we do something about its main cause, which is pollution. Pollution comes in many form. There is pollution coming

from the burning of plastic waste, pollution arising from the burning of fossil fuel in order to produce energy, and pollution coming from vehicles. However, the burning of fossil fuel for our energy needs is a major player in the rising levels of global warming that we are experiencing today. This is why development in the renewable energy sector is much needed to counteract the rise in global warming, and possibly revert our world’s temperature levels to normal status. Our innovation is the Piezoelectric Generator and it has two major components. The first major component of this hybrid generator is the piezoelectric generator. A piezoelectric generator utilizes vibrations in order to produce electric energy. Some instances wherein a piezoelectric generator produces electricity is when it is placed on the side of the road, or when it is placed at sea. For the former, the generator harnesses the vibrations made by the travelling cars and turning those vibrations into electric energy. For the latter on the other hand, the generator makes use of the vibrations created by the waves of the sea in order to produce electric energy. The second major component is the thermoelectric generator. A thermoelectric generator produces electric energy by harnessing the heat of its surroundings, much like how solar panels work. Some examples of electric generation by thermoelectric generators is when it is placed in homes near the oven, or even the human body. When a thermoelectric generator is placed near an oven, the excess heat from the oven allows

the

thermoelectric generator to generate electricity. On the other hand, the

natural body heat of our human bodies is also enough to allow the thermoelectric generator to produce electric energy.

Body The Piezoelectric Generator aims to benefit the world through the automobile industry. We know that automobiles consume fuel in order to get us from one destination to another. However, the process of burning fuel, and extracting fuel from the ground contributes to environmental pollution. Through our innovation, automobiles will expend less fuel in order to perform the same amount of work as before resulting in less fuel consumption which directly results to less environmental pollution. The Piezo-Thermal Hybrid Generator utilizes the electric generating capabilities of two different electric generators which is the Piezoelectric Generator, and the Thermoelectric Generator. Both generators generate electricity

generation. This ensures that this hybrid generator wouldn’t contribute to

global warming, and would further increase the knowledge of mankind to the ways that we can utilize renewable energies. The Piezo-Thermal Hybrid Generator would utilize both the natural occurring vibrations and natural occurring heat in order to produce electric energy without the need for fossil fuels. The design of our hybrid generator allows us to put it into the hood of the cars, with our first component, the piezoelectric generator being placed near the engine so that it can capture the vibrations produced by the engine; while our second component which is the thermoelectric generator is going to be placed at the hood of the car in order for it to capture all the excess heat produced by both the environment, and the engine block.

Benefits 

It can generate electricity that the car can use to lessen its fuel

  

consumption It contributes to the reduction of global warming It can provide power to electric equipment inside the car It is portable and can be easily placed under the hood of all automobiles

Interpretation of Results Based from the results of our tests, we were able to determine that this hybrid generator can decrease the overall monthly consumption of automobiles by 30% - 50% depending on the weather. We also found out that the weather doesn’t affect the thermoelectric generator as much as we

thought at first because the internal heat produced by the engine was enough to power our thermoelectric generator. The piezoelectric generator was also working non-stop as long as the car is moving and is producing the necessary vibrations in order for it to work and produce energy.

Method, Procedure, and Theory A piezoelectric generator produces electricity through the piezoelectric effect. This happens when the piezoelectric generator is subjected to mechanical stress by either hitting it or twisting it just enough to deform the crystal lattice within it without fracturing it. In the case of our product, the vibrations caused by the engine block of the car is enough to allow the piezoelectric generator to produce electricity. The additional vibrations caused by the road and the wheels of the car will also contribute to the electric generation of this generator. A thermoelectric generator produces electricity by utilizing the heat of its surroundings. A thermoelectric generator has two major components which is the p-type semiconductor (positively charged), and the n-type semiconductor (negatively charged).

Electric energy is generated when

there is a temperature difference between the two materials. The higher the temperature difference, the higher amount of electric energy produced. In the case of our product, the heat from the environment and the heat produced by the engine allows the thermoelectric generator to produce electricity. The whole system block will allow the battery to store enough power that it can utilize at any time. The two components, the piezoelectric generator and the thermoelectric generator complements each other in such a way that energy is being produced whether the car is moving or not, as long as heat is present in the area. For example, when the car is moving, both the piezoelectric generator and thermoelectric generator is producing electricity. On the other hand, when the car is not moving, the thermoelectric generator is still producing electricity as long as the car is parked in a place where sunlight is prevalent. This ensures that the efficiency of this hybrid generator is as high as possible.

Conclusion With the rising costs of fuel, finding an alternative for fuel is a must which is why this hybrid generator has the potential to become a massive money-saver for families all over the world. As we all know, fuel is needed for the lights of the car, the air conditioning system, the speakers and radio, and the charging outlets. Therefore, by storing energy in order to be used for those processes will allow people to save money on fuel. By combining two generators, there will be more electric energy that will be produced and ensures that every waste product by the automotive is fully utilized. By using this product, we can bring the down the fuel consumption of automotive to 70% of the national average.
