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?
  1. First, and most importantly, we still only recommend products that we believe add value for you.

  2. When you buy something through one of our affiliate links, we may earn a small commission - but at no additional costs to you.

  3. 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?
  1. When we find products that we believe add value to you and the seller has an affiliate program, we sign up for it.

  2. When you buy something through one of our affiliate links, we may earn a small commission (at no extra costs to you).

  3. 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.

Stay impactful,

📰 The quick summary: The first-ever diamond solar cell has been developed in the US, offering superior thermal conductivity, electron mobility, and a wider bandgap that captures more of the solar spectrum than traditional silicon panels.
📈 One key stat: Diamond solar cells can capture ultraviolet light, utilizing a range of the solar spectrum that conventional panels completely ignore, making them significantly more efficient throughout the day.
💬 One key quote: “The diamond solar cell, with its extremely high efficiency, superior durability, and ability to transform pollutants into energy, presents a real promise of profound innovation in the clean energy sector.”

1️⃣ The big picture: Scientists in the United States have created the world’s first diamond solar cell, marking a potential revolution in solar technology. Unlike traditional silicon panels that have efficiency limitations, diamond cells leverage extraordinary thermal conductivity and electron mobility properties. These diamond panels can capture more of the solar spectrum, including ultraviolet light that conventional panels miss entirely. Beyond efficiency improvements, these innovative cells offer exceptional durability, making them suitable for extreme environments from aerospace applications to desert regions.

2️⃣ Why is this good news: Diamond solar cells promise to dramatically increase the efficiency of solar energy capture while requiring less physical space, potentially driving down renewable energy costs. Their ability to dissipate heat faster prevents the efficiency loss that occurs when conventional panels overheat. Even more remarkable, these cells can be manufactured using atmospheric CO2 and methane, effectively turning greenhouse gases into clean energy solutions. The exceptional durability of diamond materials means these panels could last significantly longer than current technologies, especially in harsh environments.

3️⃣ What’s next: Researchers now face the challenge of reducing production costs that currently limit commercial viability. Ongoing work focuses on optimizing the chemical vapor deposition process by using simpler carbon-hydrogen mixtures. As manufacturing techniques improve, expect diamond solar technology to move from experimental status toward becoming a new industry standard.
