Meet Mensah Yeboah Thompson, a member of DDN Global and a passionate innovator in renewable energy. Based in Dormaa Ahenkro, Mensah has been focusing on two major projects: bioenergy and solar distillation. In this blog post, we’ll explore his drum type biogas digester and solar distillation system, and how these projects are contributing to a sustainable future.
Mensah’s biogas digesters are a simple yet effective way to manage organic waste while providing a cheaper cooking gas alternative. The digesters consist of two drums with three inlets/outlets. The 4″ clean inlet on top of the drum is where organic waste is fed into the digester, while the 3/4″ gas line on top of the digester is where the gas is harvested. The other 3″ pipe on the side of the digester is the outlet where the digestered slurry or overflow effluent can be collected for use as a liquid organic fertilizer.
But what makes Mensah’s biogas digesters unique are the two filters he uses. The first filter is halfway filled with water, which naturally forces the gas through the water to dissolve the carbon content. The second filter contains steel wool, which reacts with the hydrogen sulfide in the biogas to produce clean gas that can be compressed without corroding the cylinder or burner. Overall, these biogas digesters provide a sustainable way to manage organic waste while reducing carbon emissions and providing a valuable byproduct in the form of organic fertilizer.
In addition to his biogas digesters, Mensah is also working on a solar distillation system that aims to provide clean and potable drinking water without the use of chemicals. The system consists of black-coated cylinders with inlet and outlet pipes, an insulated case, reflective panels, and a plane mirror or glass on top. As the sun rays hit the reflective panels, the heat is transferred to the black cylinders, which absorb the heat and generate vapour from the water inside. The vapour is then condensed into potable drinking water in the outlet pipe.
While the prototype is still in progress, Mensah’s solar distillation system has the potential to provide clean drinking water to communities without access to clean water sources. This would not only improve the health of individuals but also reduce the need for chemical treatments that can harm the environment.
Overall, Mensah’s projects in bioenergy and solar distillation are prime examples of how innovation and skills can contribute to a sustainable future. By providing cheaper cooking gas, reducing carbon emissions, providing organic fertilizer, and producing clean drinking water, these projects have the potential to make a positive impact on the environment and society. We applaud Mensah’s efforts and hope that more people will be inspired to innovate for a sustainable future.
