With power generation in the grid becoming more diverse and decentralized, energy storage is becoming more and more important. Eduard Heindl‘s gravity storage is an approach to storing electrical energy as potential energy by lifting huge masses cut out of the ground. While this sounds crazy, there are lots of reasons why this makes sense. In the episode we discuss then need, the general approach, the construction process and some of the engineering challenges. We also look at the innovation process, the path from the idea to something that is ready to be built.

In mid-September I drove to Illesheim Army Airfield to meet with Caleb Marheine who flies the AH-64 Apache helicopter there. We talked about the helicopter’s systems, the cockpit, aspects of flying it as well as some of the missions.

On October 20, the BepiColombo started its flight to Mercury on an Ariane 5 from Kourou. I was at the launch press event at ESOC in Darmstadt to follow the launch and to record a couple of interviews. The episode consists of three major parts. The first part is an interview with Pablo Munoz about mission analysis and flight dynamics. The second part looks at the science with Joe Zender, Roberto Peron, Ajako Matsuoka and Joana Oliveira. And part three are multiple short takes with Paolo Ferri, Andreas Rudolph and Fabian Luedicke recorded in the middle of the night at ESOC.

Since this episode has been “accelerated”, the shownotes will be delivered later.

CRISPR is a family of DNA sequences in bacteria and archaea that are a part of these organisms’ cellular defense system. A recent discovery showed how this mechanism can be used to edit genes much more easily than legacy methods. In this episode I chat with Sam Sternberg about the naturally occuring CRISPR systems, how they work, and how CRISPR together with its associated enzymes can be used to cut, and subsequently, edit, DNA. We conclude the episode with an outlook on the potential use in medicine.

I chat with Daniel Geaslen about bush flying. His (at this time, former) job is to fly Kodiak turbo props for Mission Aviation Fellowship in Papua Indonesia, supplying remote villages. We cover the airplane, the missions, as well as the flying itself, with a particular focus on weather and challenging airfields.

A few years ago, I interviewed Arjen Lucassen about his wonderful music and how he makes it; obviously, I am a big fan! Recently, his Ayreon universe was performed live on stage and I was blown away. I decided I had to talk the the guy behind the live shows, Joost van den Broek. Luckily he agreed. So I visited him in his studios and we talked about music production and arrangement in general, and specifically for the Ayreon live shows.

You can buy the Ayreon Universe here ar Arjen’s shop and of course at Amazon.

In this episode I talk with NASA Armstrong’s chief scientist Al Bowers about the research projects he has been involved in during his long career at NASA. We cover deep stall research with a Schweizer sailplane, high-alpha flight and thrust vectoring with the X-29, X-31 and F-18 HARV, aero-tow of fast jets with the F-106, supercritical wings with the F-8, as well as space related projects using the SR-71 and the X-30. This is one of my favourite episodes of all time, since it is a bit of trip down memory lane for me personally, and Al perfectly hits the sweet spot between recounting facts and telling anecdotes.

I met Al when I was visiting NASA Armstrong in early 2017; this episode is a continuation of the conversations there about full-scale and subscale research there.

Effects devices are essential for electric guitars and keyboards because they shape sound and make it interesting; many classic devices exist. However, those are rare and/or expensive, plus, even if they are not, carrying them around on a tour costs money. This is why these hardware devices are simulated in software, and distributed as plugins for audio software. Native Instruments is a manufacturer of such software analog effects packages. In this episode I chat with one of their engineers, Julian Parker, about how this software simulation of the electronic hardware is done.

Superconductivity, the ability of a material to carry electrical current with zero resistance, is a surprising property of nature, which man has been able to exploit in many ways, in particular, for high-performance magnets. Those are used in magnetic resonance imagers, but also in colliders and fusion reactors. In this episode we discuss the basics of superconductivity and its uses with Pierre Bauer, a superconductor engineer at ITER.
