Sargassum is a natural, even essential, part of the Caribbean's ecosystems but these recent blooms are having a devastating impact on the region, both ecologically and economically. Many tourist areas and islands were inundated this year. It piles up on beaches, sometimes many feet thick covering a large area of shore waters, and begins to decay. In the process of decay, the hydrogen sulphide that gets released smells like rotting eggs and many resorts had to close their doors. Hydrogen sulphide is dangerous to humans in large quantities, causing headaches, dizziness, nausea and even asthma has been reported in some local communities. Since the species are Sargassum natans and Sargassum fluitans float they block sunlight creating a dead zone beneath them because plants below need sunlight to survive. The cleanup and removal of Sargassum is an expensive task because they come in large quantities at a fast rate which makes the traditional and modern clean up method very high cost dependent.

This project is about building a semi automated cleanup mechanism that can clean and collect the piled up Sargassum in shore land without ground accessibility interference. This is done by building a small scale locomotive Sargassum gathering device that is powered by a battery which can be pushed and pulled by a human being to collect the piled up Sargassum easily from one place to another. This device consists of a battery, electric motor, three rotating blades, two pulley systems, one conveyor, a holding tank, a handle and four wheels. The three rotating blades collect the piled up Sargassum on the ground by picking them up and hold the Sargassum on their holding structure. As they rotate on the axis of the electric motor which is installed inside the hallow shaft that powers the rotation of the blades, each blade will drop the Sargassum they collected on a conveyor which is powered by the electric motor through one of the pulley systems that connects the rotating shaft of the blade with the conveyor system. The main purpose of the conveyor system is to transport the collected Sargassum from the blades to the holding tank structure. The two ends of the conveyor are connected through the second pulley system. The system has two larger wheels at the front for better stability of the blades and two small wheels at the back. At the back there is a handle that that is used to push and pull the device from one location to another.

As an option depending on the performance of the electric motor, it can be connected to the wheels to drive itself through a gear system which will complete the automation of the system but since the mechanism will not have higher weight a human laborer can operate the system by pulling and pushing it. This will increase the efficiency of workers who consistently collect the piled up Sargassum with the aid of shovels.

    I have dedicated my life for invention and research because not only I have big dreams but also it is my only way out of poverty. We all have a talent we know or did not find out yet. Mine happens to be inventing. I discovered this talent of mine when I was in second year student during my university life. Starting from that point everything seemed not important except creating new ideas. So, until now I have invented more than 50 inventions which are new to the world and the rest are intended for Ethiopia that will change the life of many people including mine. But because of poverty, theft and many reasons I could not manage to make it. But all that matter is I will never give up. I will invent until and after I become successful. That makes me a strong entrepreneur. My skills are aided with a mechanical engineering degree on design, production and sales expertise.
