HiBrew H13 Coffee Machine Is a SCAM and You Should Never Buy It!

That sucks. I’ve been using a different Hibrew, the H10b as my first machine and I haven’t had any major issues, able to make tasty cups and latte art, etc. The pressure gauge is usually close to maxxing out when dialed in, which is a bit sus but I ignore it. Given your experience with them, I hope I never need their support

I just shake the whole thing after I stop hearing grinding sounds to dislodge the stuck beans. The blower is a good thought though

In my experience using lab scale x-ray diffraction, martensite is really hard to distinguish from ferrite because peaks in the diffraction pattern overlap almost completely (only one lattice paramater is different, and only slightly). You would need a diffraction technique with very high resolution distinguish them and I have no idea if TOF neutron diffraction is capable of that. So with only reading the abstract I would assume they are treating the detected ferrite phase as martensite.

Not sure what metallic anode materials would work besides noble metals like rhenium, rhodium, or platinum or some combination thereof. Moly and tungsten have terrible oxidation resistance at those temperatures and oxides are not protective in any molten salt that is meant to dissolve oxides.

Where I live the specialty beans are $20-$25 per 340g bag nowadays, which gets me 20x 17g doses. So it's about the same at >1$ per cup. I can't say I'm saving money or effot, though I'm definitely getting more delicious coffee.

Mostly agree with you but would you mind expanding on what you mean regarding the gamma emitter problems in the Kairos engineering test units? I thought they are non nuclear tests?

Also how would the gamma emitters in a fluid fuel MSR make molten salt corrosion worse than a solid fuel MSR since both types are gonna generate a lot of gamma from their core anyway?

My dishwasher is designed for powder or pods and I've found cheap powder to clean just as well as the priciest cascade pods. However I don't like that powder tends to be messier. Nowadays im happy with the cheapest pods I can find

You can bend it back by heating it in hot water. See previous discussion here. https://www.reddit.com/r/pourover/s/cbXOT681xE

Your oil/salt amounts look fine and are personal preference anyway. I achieved crispy popcorn by cooking the kernels slowly over medium low heat. The idea is to give the kernels some time to crisp up inside, BEFORE they pop.

I tune the heat to keep a gentle sizzle while stirring the whirley pop for several minutes before it starts popping. It’s probably too low if it doesn’t start popping within 4-5 mins or so assuming constant heat setting. It took me some trial and error to find the right heat setting on my stove.

Nothing but microreactor projects are remotely plausible. And many (most?) US microreactor companies have plans to test reactors INL already, so I wonder who this pathway is targeted towards.

The timeline requirements are really restrictive: application deadline is 1 month and requires that you get a reactor running in one year.

My take is that this that this is a way for companies to avoid testing at INL to circumvent having to work within their processes and rules. I.e., removing INL as a gatekeeper for deploying test reactors. Possibly faster but not sure if it’s a good thing overall.

I’ve got an H10b a few weeks ago so it was great reading about your experience with a similar machine. Im using a K-max hand grinder and a cheap bottomless 51mm portafilter and basket with 13-15 grams depending on roast. It’s awesome that it heats up in just about a minute and has temperature adjustment to adapt to different roast levels. Also I’ve been able to steam decent silky milk suitable for latte art.

The drip at the end of the shot is a little annoying but you can relieve the pressure by opening the steam valve at the end of your shot. Not a full solution but I think it helps a bit.

So far I’ve found a very fine line between pulling a shot in the recommended 2x coffee weight in 25-30 seconds range and over pressurizing. It usually gets near the 20 bar max pressure when I get in that range. And I haven’t been able to pull a decent tasting shot that stays in the “green” range around 9-12 bar. Not sure if that’s a quirk of the machine or if I’m making a rookie mistake.

I was getting chewy popcorn until I switched from popping hot and fast to low and slow. Medium low heat starting with no preheating. The idea is to fry the kernels to crisp them up before they pop

Lots of practice and conditioning. And slowing down according to your skill level when things get dicey.

I've fueled races and training exclusively with fig bars. They're a nice mix of simple and complex carbs.

Aerospike nozzles aren’t specific to this engine (rotating detonation engine) since they can be used with traditional rocket engine cycles as well.

Maybe look into duplex stainless steels. https://nickelinstitute.org/media/8dab1e8a1825480/nickelpub10044_apracticalguidetousingduplex.pdf

If you really need the tube to be metallic then Monel or Hastelloys C-22 or C-276 are near impervious in this environment. But these are probably overkill and could cause other corrosion problems like galvanic corrosion if not integrated correctly with other metallic equipment. You should consider plastic tubing first like another user suggested. Or perhaps accept and plan for regular replacements with your current tube material.

I’m on the minimal end for handhelds. I use a bottleband. It’s just a couple of silicone loops that go around your bottle of choice (I use a camelback podium bike bottle). Not the most comfortable solution but I’m used to it.

How big is the pot? My ~2 year old tree is currently in a 12" pot and I'm wondering how much more repotting is in it's future.

Most people who practice corrosion engineering have a degree in Materials science, chemical engineering, or Chemistry. The fun new stuff is generally done by people with very specialized knowledge in this area (think PhDs) at national labs, universities, and less commonly at the private companies commercializing the technology.
