Our science expo is experimenting with the energy that can be generated from ocean waves by using an oscillating water column, and if this method of energy production was sufficient to power a 5mm LED bulb. We commenced this research because we were intrigued in the workings of electricity and had an ambition to uncover a new way of generating eco-friendly electricity that is easily accessible. We wanted to utilize a renewable energy source due to all the disputes over how our environment is being negatively impacted; we needed to learn about an energy source that would not destroy the environment further. Our idea is to utilize an oscillating water column to generate electricity by using ocean waves. An oscillating water column works when it is placed below the waterline. As the waves approach, the water will enter the opening of the water column and force the air inside to compress and rush past the turbine. The turbine will rotate at a medium velocity, thus generating energy. As the wave recedes and the water flows outwards, the air that was compressed inside, will exit the column with the same rate of speed and turn the turbine once more, producing a frequent flow energy. We first heard about this experiment through the website Science Buddies, then researched further about wave energy and found an article that sparked our interest some more. The article informed us that utilizing the up-and-down motion of ocean waves could produce electrical energy. We have high hopes in lighting a light bulb that needs 1 or 2.4 watts to turn on by powering it using the water column. Using water and oscillating columns as one of our main assets to arrange an environmentally friendly benefactor of electricity is our ultimate goal.
