Harvesting rainwater’s something all of us should do. Apart from giving us access to fresh water, it can also help harness energy. How so, you ask? The REGN, a rainwater energy harvester, is a simple attachment that allows the rainwater runoff from your roof to generate electricity. The REGN is modular, and attaches to any existing pipeline. The flow of water forces an inner spindle to rotate and generate a charge using electromagnetic induction. The modular nature of the REGN means multiple units can be added in succession, allowing one to harvest fresh water as well as fresh and clean energy!
The REGN is a Red Dot Design Award winner for the year 2015.
