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: Researchers at Aarhus University have developed bacteria-powered cement that can store and regenerate electricity, functioning as a living supercapacitor that could transform buildings into energy storage systems.
📈 One key stat: A room constructed with bacteria-powered cement could store around 10 kWh of electricity, enough to power a standard enterprise server for an entire day.
💬 One key quote: “The integration of structure and function represents a significant advancement.”
1️⃣ The big picture: Scientists from Aarhus University have created a revolutionary material by embedding living bacteria into cement, transforming it into a dynamic energy storage system. This bacteria-powered cement functions as a supercapacitor that can store and release electricity while maintaining the ability to recover its performance when fed with nutrients. The material outperforms traditional solutions and remains functional even after the microbes die, with researchers able to revive its capabilities by introducing nutrients. This innovation marks a significant shift in how we view building materials, suggesting a future where structures not only provide support but actively participate in energy systems.
2️⃣ Why is this good news: This innovative material addresses critical challenges in sustainable energy storage by using abundant, low-cost materials instead of scarce resources like lithium or cobalt. Buildings made with bacteria-powered cement can store substantial energy within their structural elements, reducing reliance on external power sources and supporting the integration of renewable energy systems. The cement maintains functionality in extreme environmental conditions and can recover up to 80% of its original storage capacity when revitalized. This technology opens new avenues for eco-friendly building practices and represents a broader trend toward integrating biological processes into technological solutions, advancing sustainability goals.
3️⃣ What’s next: Researchers will continue refining this technology to enhance performance and durability in real-world conditions. The next phase involves scaling up production and testing the cement in actual building projects to validate its effectiveness. Industry partnerships will be crucial to accelerate adoption and integrate this innovation into standard construction practices.
