Originally, our main objective was to produce “unlimited energy” using magnets. However, as we progressed through our experiments, our initial idea no longer seemed so feasible. We discovered the law of conservation of energy the hard way. With our original idea shot down. We started to turn our heads and look closely into how we can harness energy in our everyday lives. Driving is one of the many tasks that humans do on a daily basis, and we both agreed upon using the wind passing by cars as our source of kinetic energy because wind energy was one of the most efficient energy sources. Right away, we got to work. One of the biggest hindrances that we had to surmount was: how could we harness the wind energy of a moving vehicle, without decreasing the overall performance of the vehicle itself? Our solution was to make our invention small and compact. With a small wind generator, we would be able to gain energy instead of losing it because the car is going to be heavily affected by the air drag caused by a bigger wind generator. To make our invention portable and convenient, we utilized the magnets bought for our first attempt. The magnets would be able to secure the wind generator in place, yet make it easy enough for the user to detach the machine off of the roof of their vehicle. As smartphones are the centre of people’s lives nowadays, our invention could help charge up a portable charger on the go. We used a sealed lead acid battery to exemplify the fact that the generator truly does work. However, any type of battery can be used in place of that by changing the connector. As our machine is very cheap to make and can be made using scrap materials, it can be a simple addition to people’s cars. This could also save some money as it will potentially reduce the electricity bill - I have found that we use an absurd amount of electricity charging our devices.
