Props & Materials Required

  • Acrylic water dam model with sluice gate mechanism
  • Water turbine wheel connected to 5V DC generator
  • INA219 voltage & current sensor module
  • ESP32 controller board
  • 16x2 LCD display screen
  • DFPlayer Mini MP3 module + 3W speaker

Step-by-Step Instructions

1

Fill Reservoir Tank

Fill the dam reservoir with water.

2

Open Dam Sluice Gate

Open the dam sluice gate. High-pressure water shoots out through penstock pipe.

3

Rotate Turbine Generator

Water jet spins turbine wheel fast! DC generator converts kinetic energy into electricity.

4

Read Hydroelectric Power Output

LCD displays 'Voltage: 4.8V | Power: 1.2 Watts! Village lights powered!' Speaker discusses dam social impacts.

Why It Works & Notes

No Place for Us? examines social and environmental impacts of large dams (clean electricity vs displacement of river villages). Building a working water turbine generator quantifies how gravitational potential energy converts into electricity.
