UK Fusion Device Receives Components That Withstand Temperatures Hotter Than The Sun
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.
Stay impactful,

📰 The quick summary: The UK’s MAST Upgrade fusion device has received critical heat-resistant components that can withstand temperatures hotter than the sun, advancing the development of practical fusion energy as a clean power source.
📈 One key stat: The waveguide components can withstand temperatures exceeding 5,430 degrees Fahrenheit, enabling the MAST Upgrade to test critical plasma heating methods necessary for future fusion power generation.
💬 One key quote: “We’re extremely proud of our team’s expertise and innovation,” stated James Anderson, manager of the RF Technology Group for General Atomics.

1️⃣ The big picture: The United Kingdom has made significant progress in fusion energy research with its Mega Ampere Spherical Tokamak (MAST) Upgrade fusion device. Recently, the project received specialized corrugated waveguide components from General Atomics that are essential for testing innovative plasma heating methods. These components enable the transfer of high-power radiofrequency waves that heat and control the charged particles within plasma to temperatures hotter than the sun. This advancement represents a crucial step toward harnessing fusion power – the same process that powers stars – as a clean, safe, and virtually limitless energy source for our planet.
2️⃣ Why is this good news: These specialized components allow scientists to test the Electron Bernstein Wave heating technique, potentially revolutionizing how fusion reactors maintain the extreme temperatures needed for fusion reactions. The partnership between the UK Atomic Energy Authority and General Atomics demonstrates successful international collaboration in tackling complex energy challenges. Advancements in fusion technology could deliver a power source that produces no greenhouse gases or long-lived radioactive waste. Progress in plasma heating techniques brings us closer to commercial fusion power plants that could provide abundant baseload electricity while addressing climate concerns and energy security needs.
3️⃣ What’s next: Researchers will now commence testing the efficiency of the Electron Bernstein Wave heating technique using these new components. The insights gained from these experiments will help reduce risks associated with high-power microwave systems in future fusion reactors. Beyond the MAST Upgrade, this research will inform the design and operation of next-generation fusion power plants currently in development worldwide.
