Our Goal
Why?
How?
Piezoelectric Road Harvester
Small square units that recover energy when run over by vehicles, bouncing back every time.
Display Prototype
Unit Prototype
Aluminum Plates
Two layers to distribute stress
Springs
Contact Time ↑ → Overall Output ↑
Padding – Dampening
Pressure on specific points ↓
Piezo Discs
Kinetic energy → Electrical Energy
Features
Durability
Able to withstand being run over by cars
Efficiency
Increased power: Area under the curve prolonged by springs
Savings
730,000 x 0.000006 x 32.47 x 8332 = Potential for up to S$11,849 saved annually
Vehicles kWh cents units
Jet Blast Wind Harvester
A wind turbine that can harvest energy during plane tests. Comes with a windbreak fence to protect it from high wind speeds.
Simulation Process
CFD Simulation without Fence
To understand wind flow around the jet blast deflector alone
Through Fence
The wind speed after the windbreak fence
With Turbulence
Creating a more realistic wind profile
Wind Turbine Model
To approximate energy output
Final Model
Overview of system, with a wind turbine and a windbreak fence integrated with the already existing jet blast deflector.
Savings
460 x 568 x 32.47 x 2 = Potential for up to S$169,675 saved annually
