How Underwater Sound Waves Enhance Wave Energy by 300%
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: New research shows how underwater sound waves can enhance wave energy capture by over 30%, making ocean wave power more viable as a major renewable energy source.
📈 One key stat: Ocean waves generate 50-80 trillion watts of power globally – up to three times the world’s current annual energy consumption.
💬 One key quote: “Our research findings show that triad resonance can increase surface wave heights by more than 30%.“
1️⃣ The big picture: Scientists have discovered a promising new way to harness ocean wave energy more efficiently using underwater sound waves. By matching sound wave frequencies to surface waves through a phenomenon called triad resonance, researchers can increase wave heights and power output significantly. This breakthrough helps address a key challenge that has held back wave energy from reaching its full potential as a renewable energy source. The same technology also shows promise for tsunami early warning systems and potentially even reducing tsunami wave heights.
2️⃣ Why is this good news: This advancement makes wave energy more viable as a major renewable energy source by improving efficiency of existing wave energy devices. The technology creates a path to tap into the massive untapped potential of ocean waves, which could generate several times more power than current global energy usage. Beyond energy, the research has additional applications in improving tsunami warning systems and coastal safety. The solution builds on existing acoustic wave generator technology, making implementation more practical.
3️⃣ What’s next: Researchers plan to conduct numerical simulations and small-scale laboratory experiments to refine the technology. They need to develop methods to use acoustic energy efficiently while minimizing energy waste. Work is also needed to scale up existing acoustic wave generator technology to the required size for real-world applications.
