Electricity supply from the national grid in rural communities in Nigeria is rarely available, making it practically difficult for farmers to preserve their fresh commodities. Poor cold chain infrastructure is a major contributor to the high postharvest losses of fruits and vegetables, which are estimated to be about 50%. While solar-powered cold storage offers great potential in providing sustain
In addition to providing foreign exchange to Uganda, fish is one of the commodities that can provide the best proteins to improve nutrition especially in children and pregnant women and hence support food security. Efforts have been made to enhance the production of fish by encouraging aquaculture to bridge the gap of the declining capture fisheries, targeting 1,000,000 tons of fish production fro
The growing push for sustainable automotive solutions has motivated the replacement of conventional engine-driven air-conditioning (AC) systems with renewable energy alternatives. This paper presents the design and simulation of a wind-powered AC system for vehicles, integrating a horizontal-axis wind turbine and power electronics to supply a standard vehicle AC unit. The methodology centers on a
This study systematically reviews the potential of electric vertical take-off and landing (eVTOL) aircraft in advancing Urban Air Mobility (UAM) as a sustainable transport innovation, following the PRISMA 2020 protocol. A comprehensive search in Scopus and manual reference chaining using terms such as “Electric Vertical Take-Off AND Landing”, “eVTOL”, “Urban Air Mobility”, and “Transport” yielded
