ECOFest 2023 - STEM Hydro Battery Example

Demonstration of using Pumped Hydro as a Water Battery

ECOKids: Grab 2 pieces of bark and place one in the top and one in the bottom. Now if I turn both these taps on simultaneously, which piece of bark will get to the end first? Adults and 8+ kids learn from this and usually make the mistake that the pipe with the downward flow will beat the flat pipe. Younger kids have fun racing the boats.

Equipment:

Improvements:

Need to use a Plastic blue drum next time. Its surprising how quickly the oil drums rust with water standing in them. Automatic pump start somehow, We Need a separate float that is lower to the ground.
