Waterwheel concept Powers Lightbulbs with Water Pipes

Waterwheel concept Powers Lightbulbs with Water Pipes

The problem with that (besides the fact that Africa is a continent and not a country...) is that places without electricity to run lights most likely don't have pipes with running water. These would probably be areas where people have a communal well where water is pumped, or, more likely, women and girls have to travel long distances to collect water. Even if an area does have water infrastructure, the pipes need water flowing through at a steady enough rate to fully charge a battery, which further decreases the practicality of the design. So the locations where this can be applied are severely limited, unless it is considered more of a novelty product for off-grid lighting in developed areas than a needed tool in developing areas.
