hi marine, The calculations around the turbine are under way and progressing well. The turbine is big because the speed of water is slow, hence the increase in the surface area to trap more water energy.
hi everyone, Thanks in the first place for asking question on Mr. Robert Shimaingo's under water dam free turbine. My gratitude also goes to Mariana and her team for making this possible. will answer the questions based on the guide from Jona Repishti - IDIN coordinator and they are as follows:-
1. How much it might cost to build/deploy? The building of the project from the Rafts, making of the blades,shaft, gear box selection(ratio of 1/32), alternator (3kW). the cost will range from 9000 USD to 10000 USD appropriately depending on the market where materials has to be bought. this amount excludes labor fees.
2. What are the gains that it might yield (both in terms of savings from not having to purchase ice/electricity, as well as any additional income fisherman can gain from the ability to chill their catch) Traders buy ice from far places and transport the ice to the river banks and island by road covering a distance of 70km and more. This is very costly on their part and also the ice mostly melts as they are going to fishing bases and also as they wait for the fishermen as they come from fishing. With this innovation, the traders will not be buying ice from far place instead, they will just be buying frozen fish and ice from the fish camps where there is refrigeration. Also the fishermen are restricted on the amount of fish they catch due to the fact that they do not have storage facilities for fresh fish which is on high demand in the Zambian region. Having a storage facilities will mean they will be able to catch fish in large quantities and stock them safely in the fridges awaiting traders. In addition, other fishermen paddle a long distance from their bases just trying to sell their fish before it get wasted there by risking their lives at night. with the introduction of the turbine power, they will be stocking fish in their fridges awaiting fish traders to buy from their islands. 3. How has the current iteration been tested in front of potential end users? It has been overwhelming filled with positive comments and suggestions of having more turbines of such type spread at each island or river bank. The traders are praying that the turbine can start work as soon as possible for it will be cost saving for them. 4. How is it measuring impact? once operational, the fishermen along Kafue river will greatly benefit from this service as well as from other parts of the country where they do fishing at a medium scale. This will proved provide lighting in their houses. we are talking of fishing camps having families between 30 to 500. if all of these can be benefiting from this innovation, their livelihood will be improved. 5. How many fishing communities are living in the banks along the river? Do they all fish at a similar scale? How many communities at the same time would be able to benefit from a single turbine? The target area of Mr.Robert is at least to cover 20 fishing camps. YES, the fishermen all fish at a similar scale due to the reason that don't have storage facilities for fresh fish. Benefiting from a single turbine will on a single of the storage facilities available at a particular fish base. the turbine will be able to power 10 refrigerators. therefore, to our estimates, we expect to cover four or five communities benefiting from one turbine.Nevertheless,for start, it will be a challenge due to the fact that only one refrigerator of 500litres is available in readiness for commissioning. Thanks for your time, Sydney.
