My original question was very nearly: can this be used in guttering? I figured that the non-constant flow would probably make it uneconomical.

- manigandham 9y agoYes, and the maintenance issues of using that waste flow.
- rtkwe 9y agoIt has a more fundamental problem because there's just not that much rain falling on most roofs outside of places with monsoon seasons. Because of this even with cheap efficient energy storage there's just not very much there to harvest.
- ProblemFactory 9y agoTechnically yes. But there just isn't enough potential energy in the water falling on a typical house. For example, US average yearly rainfall of 76cm, on a 10m*15m roof, at height of two stories at 5 meters, would give you 1.5kWh of energy per year. That's enough to run the appliances in your home for an hour. You might be in a more rainy location, or have a larger home, but the end result is still insignificantly small.
