New Rain Energy Harvesting System Turns Wet Weather into Electricity
Affiliate Disclosure
Hey fellow impactful ninja ?
You may have noticed that Impactful Ninja is all about providing helpful information to make a positive impact on the world and society. And that we love to link back to where we found all the information for each of our posts.
Most of these links are informational-based for you to check out their primary sources with one click.
But some of these links are so-called "affiliate links" to products that we recommend.
Why do we add these product links?
First and foremost, because we believe that they add value to you. For example, when we wrote a post about the environmental impact of long showers, we came across an EPA recommendation to use WaterSense showerheads. So we linked to where you can find them. Or, for many of our posts, we also link to our favorite books on that topic so that you can get a much more holistic overview than one single blog post could provide.
And when there is an affiliate program for these products, we sign up for it. For example, as Amazon Associates, we earn from qualifying purchases.
What do these affiliate links mean for you?
First, and most importantly, we still only recommend products that we believe add value for you.
When you buy something through one of our affiliate links, we may earn a small commission - but at no additional costs to you.
And when you buy something through a link that is not an affiliate link, we won’t receive any commission but we’ll still be happy to have helped you.
What do these affiliate links mean for us?
When we find products that we believe add value to you and the seller has an affiliate program, we sign up for it.
When you buy something through one of our affiliate links, we may earn a small commission (at no extra costs to you).
And at this point in time, all money is reinvested in sharing the most helpful content with you. This includes all operating costs for running this site and the content creation itself.
What does this mean for me personally?
You may have noticed by the way Impactful Ninja is operated that money is not the driving factor behind it. It is a passion project of mine and I love to share helpful information with you to make a positive impact on the world and society. However, it's a project in that I invest a lot of time and also quite some money.
Eventually, my dream is to one day turn this passion project into my full-time job and provide even more helpful information. But that's still a long time to go.

📰 The quick summary: Scientists developed a new system that harvests electricity from falling raindrops with unprecedented efficiency, creating a way to generate renewable power during wet weather when solar panels are less effective.
📈 One key stat: A single tube in this innovative system produced 440 microwatts of electricity, converting more than 10% of falling water’s energy – 100,000 times more efficient than continuous water flow methods.
💬 One key quote: “According to lead researcher Siowling Soh, rain falls from a few kilometers up in the sky to the earth, so there is a lot of room in three-dimensional space to harvest rain energy.”
1️⃣ The big picture: Scientists have discovered a breakthrough method to generate electricity from falling raindrops that could transform renewable energy production. The system uses vertical tubes about 12 inches tall where water droplets create electricity through charge separation as they fall in a specific pattern. Unlike traditional hydropower, no turbines are needed, and the process is remarkably efficient. In successful tests, researchers powered multiple LED bulbs using just four tubes, demonstrating potential for rooftop systems that could turn rainy days into power sources for homes.
2️⃣ Why is this good news: This technology opens up a completely new source of renewable energy that works specifically when other sources like solar might be underperforming. The system harnesses energy that would otherwise be completely wasted, using gravity rather than energy-consuming pumps. With its impressive 10% energy conversion efficiency, the technology shows practical potential for real-world applications. Homeowners could benefit from lower electric bills during rainy seasons, creating a more resilient and diversified clean energy ecosystem that works regardless of weather conditions.
3️⃣ What’s next: Researchers are now working to improve the system’s efficiency and scale it up for practical household use. Future versions might integrate the technology into existing rain gutters or downspouts for easy installation. Scientists also need to develop effective storage systems to make the electricity available when needed, not just during rainfall.
