Introduction: Rainwater Dynamo
We made electricity from rainwater. You need:
a bicycle dynamo
a small plactic cotainer (yoghurt container)
8 plastic spoons
some wooden sticks and nails
a cone (we made it with a 3d-printer)
Step 1: Making the Waterwheel
Tape the dynamo to the top of a upside-down container. Then glue the plastic spoons to the head of the dynamo. So you get a whaterwheel. Example of a container on top.
Step 2: Making a Container for the Water
Make with the sticks a frame for the cone so it is suspended about 30 cm in the air. Then hit a nail trought the button in the upper half and not the center so it topples over when you fill the cone with watter.
Step 3: Placing the Things Next to Eachother
Place the cone in a place where a large amound of rainwater fals. Then place the waterwheel next to it and connect something to the dynamo.
