    Context

    Pumping of water for domestic and productive uses has been difficult to maintain in Tanzania. This challenge is highly attributed by the higher costs of pumping water using conventional means such as diesel generators and electricity.

    Solar Photovoltaic (PV) technologies have enabled rural communities of Tanzania to apply this technology for lighting, water pumping, charging of cell phones, etc. Community water projects using solar pumps have benefitted from reduced running costs as compared to diesel or electric water pumps.

  • Solar water pumps

    Type: 
    Technology
    Sectors:
    Objective:

    A reliable and clean water supply is an essential need but a large number of people currently lack this basic provision. Solar water pumps is a socially and environmentally attractive technology to supply water. Especially if the need for water is in remote locations which are beyond the reach of power lines, solar power is often the economically preferred technology.

  • Efficient air conditioning systems

    Type: 
    Technology
    Objective:

    Cooling is becoming a rapidly emerging demand in developing countries, which signifies that the building design and shell measures need to reduce cooling loads, and the efficiency of air-conditioning will need to be improved. Air conditioning systems are implemented in numerous sectors, namely buildings, industry and transport. They are distinguished in two main categories, room air conditioners and central air conditioners.

GEC is dedicated to the transfer of environmentally sound technologies, in both developing countries and countries with economies in transition. The foundation aims to contribute to Japan’s international efforts on the environment, sharing project collaborations as well as promoting Japan’s rich conservation knowledge and experience in developing nations.

  • Method for Controlled Energy Addition in Storage Water Heating Devices

    Type: 
    Product
    Objective:

    The invention concerns devices for water storage heating and delivery. A storage water heater of the invention provides an amount of unmixed recently heated water from an internal small volume during a draw along with water from a main volume. When water is drawn from the storage water heater an amount of recently heated water substantially unmixed with the remaining volume of the tank is drawn along with heated water from the remaining volume.

  • Photovoltaic Reverse Osmosis System with Thermal Management

    Type: 
    Product

    Problems: 1. Solar panel conversion efficiency decreases with increasing temperature 2. The amount of energy required to desalinate water increases as temperature of the feed water decreases Technology: This invention uses photovoltaic panels (PV) to power reverse-osmosis water filtration. A thermal controller maximizes the clean water produced by a PV/RO system by managing the temperatures of the PV panel and the RO feed water in response to changes in the incoming solar radiation ambient air temperature and source water temperature.

  • Pultrusion for the production of fibre reinforced composite materials

    Type: 
    Product

    Technology Description: Pultrusion is a continuous manufacturing technique for the production of fibre reinforced composite materials of predefined dimensions. However there are some problems with the method that limit its use. These can be overcome by using new technology developed at the University. This new method ensures that fibres are spread within the bundle in the optimal way to maximise resin impregnation and ensure voids are not produced in the section.

  • Offshore Energy Harvesting Storage and Power Generation System

    Type: 
    Product
    Technology:

    Problem: Intermittency of wind energy supply from wind turbines Technology: This invention is a system for simultaneously anchoring floating offshore energy harvesting machines such as wind turbines and wave energy machines storing excess energy harvested and then generating continuous power to meet baseload demands. It consists of a subsea structure with a chamber that is anchored to the seafloor by either gravity or piles to resist mooring cable loads on the supporting floating structure used for the energy harvesting machines. The chambers are constructed from precast concrete.

  • mo-Wash Mobile Handwasher

    Type: 
    Product

    The mo-Wash is a standalone handwashing unit developed for use in off-grid and mobile applications such as weddings and funerals. The fully automatic portable floor standing mobile handwasher delivers a 10 second hand wash at the movement of a hand and does not require a foot pump which can be difficult to use.
