REGN is a rainfall energy harvester taking the guise of a simple connector insert between rain gutter pipelines. Rainfall is an often overlooked source of renewable energy due to its unpredictable nature.

The  REGN is designed to involve:
i. The efficient capture of rainfall
ii. Utilisation of rainfall (a source of natural renewable energy)
iii. Regions prone to rainy seasons?

Sustainability problem: Energy, Rainwater, efficiency

Technology:

1. The insert utilizes the motion of rainwater diverted from roofing structures along gutter pipelines to generate electricity by electromagnetic induction as magnets located on a spindle within a funnel column is spun on a plane coincident to copper coils leading to an external output connector.
2. Fluid flow was designed around a planar cross-section, the design is easily adapted to American (rectangular) and Commonwealth (circular) pipeline standards.
3. The exterior of the device is specified to be made from materials able to provide ample shielding from tropical heat and UV radiation.
4. Surfaces in contact with acidified fluid/moisture (due to contamination from airborne or surface pollutants) would be specified with materials inherently able or treated to resist corrosion).
5. REGN’s compact frame allows for practical use of magnetic levitation
6. REGN modules are ideally installed among gutter pipelines in dense urban settings.

Stakeholders:

• Investors
• Local residents
• NGOs
• Engineers
• Manufacturing companies

Next Steps

• Assess tropical cities that could benefit from this project
• Educate local citizens the importance of collecting rainwater
• Convince city department and build a partnership with them
