Bodies are odd.  Anyone who can see their own nose will tell you the same.  So will anyone whose diet changed their body odor. And so will anyone who’s ever felt their phone vibrate in their pocket only to later realize it was a phantom ring. 

Our bodies make stuff up constantly and do plenty of questionable things without asking our permission first.  It can feel disorienting, especially due to the fact that being our sole points of reference, they’re hard to see outside of.  So, people invent analogies for the body, ways to understand what it is, and how to use it. 

On this episode, Jeff interviews the operators of several bodies on the models they’ve developed to help them navigate the strangeness of the world we live in. 

Thank you Allison Behringer of the Bodies Podcast for sharing Juliana’s comic about bodies of water. And thank you Jackie Scott for helping record the freight elevator heard on this episode.

In the life of a man, his time is but a moment, his being an incessant flux, his senses a dim rushlight, his body a prey of worms, his soul an unquiet eddy, his fortune dark, and his fame doubtful. In short, all that is of the body is as coursing waters, all that is of the soul as dreams and vapors; life a warfare, a brief sojourning in an alien land; and after repute, oblivion. 
—Marcus Auralius, Meditations, c. 180 AD. Translation by Maxwell Staniforth.

HBM104: Scrapheap Reactor

Max Turnquist advises against wearing shorts while dumpster diving for used lab equipment. Almost every day, Max visits a university parking garage, where there are several small mountains of discarded equipment, some of it quite rare. It’s where he found his ion pump, and a lot of his rack-mounted monitoring gear and power supplies.  He’s building a small nuclear fusion reactor from scratch in his bedroom, and he’s doing it on the cheap.

Viable fusion power has long been a dream of scientists.  Once a fusion reaction starts, its only waste products are helium, water, and relatively small amounts of neutron radiation.  The fuel for these reactors is often Deuterium (aka. “heavy hydrogen), a common isotope of hydrogen found naturally in seawater.  Compared to nuclear fission (the nuclear tech we currently use), fusion seems almost too good to be true—nearly free energy with few downsides.

But there are a number of obstacles in the way.  Getting atoms close enough to fuse takes massive amounts of force and heat.  In the fusion reactors made by nature (stars), fusion happens because of the ridiculous amounts of gravity that create the high heat needed for this reaction.  But here on earth, where sun-like gravity isn’t an option, scientists like Max have to rely on trickier methods.

Max thinks that physicists are intuitive scientists.  They observe something many times and gain an inherent knowledge of the universe.  He says that the biggest laws that govern the physics are often quite simple, elegant.  Max found himself drawn to one of the archimedean solids, and followed his hunch.

His proof of concept reactor has a metal cage in the shape of a truncated icosahedron, a couple inches wide. In this shape, Max suspends particles in a cage of other particles.  This shouldn’t be possible, based on Earnshaw’s Theorem, which in layman's terms, means that it’s really hard to keep the particle in the middle from squirting out the sides.  But Max’s shape, along with a constantly changing voltage, suspends things in a Goldilocks-type way. He calls this “stably unstable”.

 
 

His first proof of concept worked.  Now he’s on his second. He says he’s almost ready to do a major fusion test, where he’ll drag his 300 pound reactor out to rural Maine,  bury it in the ground and stand a safe distance away (to avoid the neutron radiation). And if it works, he’ll be on to solving the next problem, which is how to actually harvest the power it generates.  

Max doesn’t think the solution is a single step away.  There are still many hurdles to overcome before fusion replaces the dirty and inefficient power we use today.  And maybe those hurdles are too many, maybe it’s a fool’s errand.  But he’s hopeful that fusion can save at least part of the world.

Correction: In the episode, we misstate the natural abundance of Deuterium. The correct abundance is .015%. We regret the error.
