Beyond Solar

Part 1: Drawing key lessons

• This project is innovative and supports sustainability by harnessing the unused kinetic energy of rainwater falling through every building’s rainwater pipes.

• To increase energy produced, the blade design was identified as one of the key areas for improvement and significant design improvements had been made after each iteration. The area of improvements then expanded to include adding gears, generators, and a storage tank.

• The project demonstrated a working prototype made using improvised materials. This prototype proved that the proposed device is working.

Areas of improvement for the project:

• It is a very innovative project with a working prototype.

• Maybe the generator can be provided with an alternative source of energy (e.g., kinetic energy from wind) when it is not raining.

• Some statistics of rainfall in Singapore (amount, duration, rainfall days) can be included to calculate how much energy can be generated.

Part 2: Exploring Possibilities

• A working prototype that exemplifies the idea is very interesting.

• Focus on an area of improvement first. Then, slowly expand the areas when one is confident.

• Gears were used in the project to relay the energy across a distance.

• Sustainability is a huge area of concern for this generation and ideas that can improve sustainability is of interest.
