This Solar-Powered Water Pump Has No Moving Parts

This water pump has no moving parts and only uses the sun for energy. It was invented by YouTuber Cody from Cody’s Lab and relies on the theory that water expands by 9% when heated. By wrapping more than 60 metres of plastic tubing around a plank of wood, then placing one side in the shade and the other side in the heat of the sun, the YouTuber was able to move several centimetres of water from one vessel to another. While it might not be the most efficient way to move water it is awesome to see an idea come to life using just the most basic of materials. While the design has a few problems, something similar could be used in applications for camping or in areas experiencing power outages. Cody said he intended to use the pump to move water around his ‘aquatic environments’.
