Solar Hearing Aid
African-Made, Solar-Powered Hearing Aid

The SolarAid is a hearing aid designed and built by Godisa Technologies, a Botswana company founded to make low-cost hearing aids for the developing world. The SolarAid system combines a small hearing aid and a lightweight solar charger; Godisa developed the first No. 13 rechargeable button battery for the system. Godisa is Africa’s only hearing aid manufacturer, and the only one in the world making hearing aids specifically for the sub-Saharan Africa environment.

Innovation through creating effective solutions using technology solutions that have existed in other contexts can have huge impacts. Appropriate technology solutions offer the opportunity for great gains for humanity.

    I read about the solar powered hearing aids somewhere else, and they sound like a great

    What wasn’t clear to me, was if these devices relied on large amounts of sunlight to
    be effective (as one might expect in Botswana), or if they are commercially viable

    I know that this post has been up a while, I’ve only just come across it now. The fact that the developing world is coming up with these things is fantastic, and obviously utilising one of their biggest resources to provide “free” power is great. But surely the Western world should be pushing for more of these type of solar powered chargers, not just for Africa but for everywhere. Sunlight and wind power have got be used more, and this hearing aid demonstrates that it can be done at all levels, from the smallest gadget to power for buildings.
