Recent research from the National University of Singapore reveals a novel method to capture renewable energy from rain, potentially transforming roofing into energy-generating structures. The study highlights that when rainwater flows through specific tubes with air pockets, it can convert about 10% of the energy in falling rain into electricity. Demonstrations showed this technology could power multiple LED light bulbs; scaling up could allow for substantial energy production for homes. While still in early stages lacking commercial designs, the approach could also be adapted for energy generation from streams without the environmental impact of large dams.
"There is a large amount of energy in rain," says Siowling Soh, an engineering professor at the National University of Singapore and author of the study, which was published in ACS Central Science.
The method makes it possible for around 10% of the available energy from the rain to be converted into usable electrical energy.
As long as we are willing to scale up the system in three-dimensional space-e.g., the lateral dimensions in addition to height-we will be able to obtain substantial amounts of energy.
The research is still at an early stage, with no designs yet that show how the system might look on a house.
