Big Ideas Only

3D printing isn’t just for fragile prototypes or weekend gadgets anymore.In this episode of Big Ideas Only, host Mikkel Svold visits the Center for Industrial 3D Printing at the Danish Technological Institute (DTI) to explore how additive manufacturing is used in real production today.The Guests of this episode Kristoffer Ryelund Nielsen (previously Head of Engineering) and Karl Frederik Fischer (PhD, Materials Science) will walk us through the machines, parts and business cases that make 3D printing a serious tool for industry.In this episode, you’ll learn about:1. Why “additive manufacturing” is more than prototyping and where it shines in production.2. Powder-based processes for plastics and metals3. How the industries are adopting 3D printing today4. The Concrete advantages in printing 3D5. Real printing examples, such as rocket components.6. Certifications and standards for medical and food-grade parts7. How does the future look like with 3D PrintingEpisode content00:04 3D printing beyond the Wish-printer stereotype01:58 “3D printing” vs “additive manufacturing” and why the term matters02:45 From prototyping to full-scale production parts06:37 When printing wins: faster lead times and optimized designs 16:57 The biggest opportunities haven't yet been discovered 18:02 Space example: consolidated rocket engines with fewer parts and better cooling 25:38 Enabling designs that were previously impossible 29:30 The future: mass customization and digital inventories This podcast is produced by Montanus.

What happens when wind and solar deliver more power than the grid can handle and batteries aren’t the answer?In this episode of Big Ideas Only, host Mikkel Svold sits down with Pat Han, Technical Director at Skovgaard Energy, the company behind what is called the world’s first dynamic Power-to-X (PtX) ammonia plant.Pat explains how “dynamic” PtX rides the ups and downs of wind and solar, turning excess electricity into ammonia. The ammonia process can start and stop quickly, that’s why ammonia is a strong first “X”, and how the sector coupling can turn rural areas into thriving energy hubs.In this episode, you’ll learn about:1. What “dynamic” PtX means and why flexibility is the missing piece for high-renewables grids.2. Why hydrogen-to-ammonia enables storage and transport.3. How the process works from water to hydrogen plus nitrogen to ammonia.4. How PtX is a flexible consumer that balances variability and prevents curtailment.5. Why market design, ESG, and value-chain planning matter more than tech.6. The social benefits with a PtX plant, such as jobs, industrial neighbors and revitalizing rural regions.7. How good local cases unlock permits, public support and future regulation.Episode content:01:20 What is Power-to-X? 08:31 Limits of batteries for grid-scale storage10:35 Why ammonia?11:56 Maritime propulsion and industrial demands 22:01 How "dynamic” is dynamic? Matching power markets without second-by-second thrash28:20 Turning stored energy back into electricity 39:34 Why real projects create the political runway for better rules.43:09 Jobs, keeping young talent local and making rural locations an advantage.48:40 Industrial symbiosis and sector coupling 51:11 Strong renewables, grid access, neighbors for heat/power synergies, supportive permitting. This podcast is produced by Montanus.

Fusion has long carried the reputation of being “30 years away”. Forever on the horizon but never quite arriving. That perception may finally be changing.In this episode of Big Ideas Only, host Mikkel Svold is joined once again by Søren Bang-Korsholm, senior scientist at the Department of Physics at DTU. This time, the focus is on the practical future of fusion energy: what private companies are doing differently, how huge global projects like ITER fit into the picture, and what role fusion could play in the broader energy transition.From billionaire-backed startups to the promise of grid-ready plants, Mikkel and Søren explore whether fusion can move beyond test facilities and become a true energy source for the 21st century.In this episode, you'll learn about:1. Why private investment is accelerating fusion research.2. The scale and goals of the ITER project—the world’s biggest science collaboration.3. How fusion could integrate into existing grids and even replace coal plants directly.4. The role of fusion as a clean, reliable base load alongside renewables.5. Potential use cases beyond electricity, including hydrogen production and desalination.6. The biggest technical hurdles still standing in the way.7. Why fusion’s commercialization might be closer than we think.Episode content:01:11 Why the “30 years away” joke may be outdated 05:14 Fusion’s role in the global energy transition09:13 ITER: the world’s largest fusion project explained12:27 Timelines: demonstration reactors in the 2030s13:22 How fusion could plug straight into existing grids18:25 What still needs solving before commercialization 30:16 Safety, waste, and why fusion differs from fission31:50 The need for public-private collaboration in energy34:17 How fusion could change daily life and global development This podcast is produced by Montanus.

What if we could power the world the same way the sun does? No carbon, no meltdown risks – just clean energy from smashing atoms together.In this episode, I sit down with Søren Bang Korsholm, Senior Scientist at the Technical University of Denmark, to talk about fusion energy. You’ve probably heard it called the “holy grail” of power, but—weird metaphors aside—what does that actually mean? And are we any closer to making it work outside a lab?We cover how a tiny bit of fusion fuel could keep your lights on for a lifetime, why plasma is such a pain to control, and whether this whole thing is still sci-fi or finally getting real.If you like science, big ideas, or just want your energy bill to stop looking like your rent, give it a listen.In this episode, you'll learn about:1. Discover why fusion energy could provide unlimited, clean energy.2. Understand the fundamental nuclear process behind fusion energy.3. Learn how fusion energy mimics the sun’s power production.4. Hear how magnetic and inertial methods can contain fusion reactions.5. Explore the historical journey from fission to fusion research.6. Find out how fusion might transform the global energy landscape soon.Episode Content00:17 Introduction to fusion energy with Mikkel Svold  01:21 Why is fusion energy a big idea?  02:11 The potential of unlimited energy sources  03:06 Comparison of fusion energy to coal energy  04:33 Understanding the basic processes of fusion  05:28 How do fusion reactions actually work?  09:03 What fuels are commonly used in fusion?  12:47 Evolution of fusion research and technology  20:54 Magnetic confinement fusion vs. inertial confinement fusion  31:30 The role of the private sector in fusion developmentThis podcast is produced by Montanus, https://montanus.coThis podcast is produced by Montanus.
