M.Item Development and performance testing of solar cookers(http://www.erc.uct.ac.za/jesa, 2007-08) Kimambo, C. Z. M.The most common type of energy used is firewood. In some Sub Saharan countries, up to 90% of total energy use is from firewood. The consumption of wood fuel is in some countries as high as twice the sustainable yield, something that has led to environmental degradation due to deforestation and scarcity of firewood. The use of fossil fuels such as kerosene and LPG for cooking is expensive. Solar energy is a non-consumptive and non-polluting fuel. It can help alleviate the problem of insecurity of cooking energy, which is the major domestic energy requirement. Several attempts have been made to introduce solar cookers in different countries and have achieved variable successes. There are still critical issues yet to be resolved in order to make that technology acceptable for wider dissemination. They include getting the most appropriate types of solar cookers for specific locations, optimum size/capacity, types of materials to be used, optimal design and affordable cost. In an attempt to resolve these issues, a comprehensive study involving theoretical review, development work, experimental testing and evaluation of solar cookers was conducted for several years on six different types of solar cookers. The cookers are the ‘SunStove’ box cooker, wooden box cooker, panel cooker, reflector cooker with unpolished aluminium reflectors, reflector cooker with polished aluminium reflectors and reflector cooker with glass mirror reflectors. This paper presents the results of the study. Results obtained indicate that many of the cookers could be used to cook food for households in areas with medium and high insolation, with appropriate selection of the type and specification of the cookers. The specification should be based on the measured insolation data of the location indication of the direct and diffuse components. As a guiding tool, reflector cookers offer best comparative performance in areas with longest durations of clear sky (greatest direct beam), panel and collector cookers under moderate cloudy conditions and box cookers under very cloudy conditions.Item Development of a compact integral solar water heater for Africa(Elsevier B.V., 1994-06) Siddiqui, K.

K.Item Enhancing Start Up and Business Growth in the Country through Establishment of the University of Dar es Salaam Business Incubator(Department of Mechanical and Industrial Engineering, University of Dar es Salaam, 2016-09-01) Nyichomba, B. B.; Kimambo, C. Z. M.This paper outlines the development of the business incubator model based on previous global and national experiences. The business incubator to be established shall be under UDSM Innovation and Entrepreneurship Centre (UDIEC) which was established on August 2015 aimed at addressing previous challenges between knowledge generation, research and application. In addition, UDIEC is aimed at addressing challenges related to imparting practical entrepreneurship skills to students, academic staff and SMEs in the country for the formation of new start-ups and increased competitiveness of existing companies. Thus, using incubator models that support business start up as well as business growth in countries such as Netherlands, India, U.K, and South Africa as well as locally established business incubators such as the Dar Teknohama Business Incubator (DTBi) under COSTECH and SIDO Business and Technology Incubator it was possible to establish an incubator model capable of supporting pre-incubation, incubation and post incubation programmes for UDSM graduates, staff, SMEs and a wider community. In other words, apart from supporting start up business, the Incubator shall also “turbo-charge” the business growth as well as providing business counselling services. The business incubator model shall be a Hybrid one comprising incubator with walls and virtue incubators. To start with, the incubator shall be capable of incubating at least 20 incubatees under the incubator with walls and about 40 incubatees will be under the virtue incubator. However, the number shall be increased depending on the needs and resource capacity to accommodate the incubatees. The financing model include the model that requires a mix of anchor tenants (those paying commercial rates for space rented); resident clients who pay a subsidized rental and a royalty payment on annual turnover generated during the incubation period and during additional years after graduation. The business incubator shall have to rely on an initial cash injection or seed money from the Government or development partners that will, over a certain number of years allow the incubator to operate and generate its own cash resources to support its activities.Item Ethanol - Activated Carbon Solar Refrigeration(University of Reading, 1986-08) Kimambo, C.
