    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

    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.

  • Semiconductor Lasers with Doping Gradients in Optical Confinement Areas to Increase Laser Efficiency

    Type: 
    Product
    Technology:

    Current semiconductor lasers are 45 to 50 percent efficient. Lowering the voltage needed for lasing to occur could increase the electrical-to-optical power conversion efficiency significantly. UW–Madison researchers have developed a highly efficient aluminum-free semiconductor light-emitting source that is particularly suited for high-power diode lasers of one-watt continuous wave (CW) output or higher.

  • 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.

  • 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.
