It seems like the approach of cooling the organism to -30C at 350MPa, and then raising pressure further to ~600Mps to freeze it could actually solve that. As far as I understand, the speed of diffusion in water it far slower that the speed of sound (speed of sound at 25C is 1497 m/s, while diffusion coefficient for protons at 25C is 9.31e-5 cm^2/s, which corresponds to 1.4e-4 m/s - 8 orders of magnitude less), which is the speed of pressure gradient propagation. So if we use raising pressure as a way to initiate phase transition, it will occur nearly simultaneously everywhere, and the solutes won't have time to diffuse anywhere.

ETA: I just realized that since diffusion propagates according to inverse square law, while sound is linear, they should be compared to each other at the shortest distance possible. So I checked the time it takes for a proton to cover 0.1nm (hydrogen atom diameter) in water - 5.37e-13s, which gives us 186 m/s. It's far greater than the original number, but still an order of magnitude smaller than the speed of sound. And if we take 4nm (the thickness of a cell membrane) we have 8.59e-10s - only 4 m/s, so it decreases very quickly, and we're pretty much safe.

First off, I love that you're actively pursuing alternative methods of human preservation. That's awesome, and I hope you manage to find some useful ideas in your search. However, I fear that this approach in particular doesn't really solve the problem that cryoprotectants successfully do (toxicity briefly aside).

without cryoprotectants the water will expand upon freezing, and break the cells.

This line in particular is my biggest point of contention. I am by no means an expert in this field, and my understanding may be moot in this context, but the expansion of water-ice crystals isn't the central concern for frozen biological cells. A quickly found source claims that:

Since ice is essentially pure H2O, ice formation can increase the concentration of minerals in the remaining cytosol to a toxic level. The increased mineral concentration in the cytosol will cause water to be drawn in from the surrounding cells by osmosis, which can cause the cell to swell and burst.

Alcor's official FAQ also says that:

When tissue is slowly cooled, ice first forms between cells. The growing ice crystals increase the concentration of solutes in the remaining liquid around them, causing osmotic dehydration of cells.

Your method doesn't prevent the formation of ice crystals, it merely changes the structure of the crystals, and at what temperature they form, so I suspect harmful cell osmosis can still occur. Of course, I could be insufficiently understanding why ice crystals effect the mineral concentration of cytosol, or the order in which certain biological areas freeze under variable conditions, and your smaller ice/lower freezing temperature would successfully prevent this issue. I don't believe this is necessarily the case, given your explanation, but if anyone who's more studied in these fields could speak up, I'd be happy to defer to their expertise.

The ritual has been completed. I await my karmic reword, as per tradition.

There was a lot of good variance in the calibration questions (for me), so nice job thinking of them! Gur ivqrb tnzr dhrfgvba va cnegvphyne fhecevfrq zr jura V ybbxrq hc gur nafjre, nf rira nf n uhtr Zvarpensg sna V unqa'g ernyvmrq vg orng bhg frpbaq cynpr ol 3 zvyyvba.

Also, in a fit of needless cleverness, I made my public key decryptable (by my private key) into a plaintext message that works as an extra layer of identification in the case that I win the money.

What about alternate measures?

Binary comparisions like: "Would I rather: Experience the previous hour exactly as it occured a second time, or X for an hour?". Where X might be : sleep, or some reference experience.

The abscence of negative mood. This isn't the same as happiness, but something like boredom or anger could have a clearer floor, or lend itself to a "Present, a little, none" scale.

Or more specific questions. Here's a PDF of an adjective based scale. An idea is to pick out only those adjectives that you already expect to vary.

I've passed 200,000 words in the story I started writing at the end of May, and as far as I can tell, I'm still on track to keep writing daily and bring it to a finish, instead of just trailing off into... well... not. That's pretty close to four NaNoWriMos in a row, with more to come. And the next story I write will be that much better for the work I've done on this one; and if I can manage my motivation so as to keep it up, I just might be able to consider myself "a writer" instead of "someone who writes".

Tsuyoku naritai!

To start off with something everyone here will be interested in, I've recently and finally finished the first part of my video version of The Useful Idea of Truth (LW post here, Youtube link here). It seems well liked, and I'm even wondering if I should've posted it to Main. To understand what finishing this project means to me may be hard, as it means a lot. I have learned a ton doing this, and am really happy with the final look. My previous video editing experience was basically putting still frames and videos in sequential order with a spoken voice overtop. I'm 18 years old. I'm 18 and inexperienced and I just made something that I consider on par with CGP Grey in production quality, and he's been making videos professionally for years. It's so great to look at one of my idols, say "I bet I could do that too," and then actually do it. There's a real-world benchmark for this skill I've never really done before, and I matched it. I'm developing as a person, learning and training new skills, and it's feeling great. Of course, at >80 hours for that 6 minute video, my production rate isn't so great, given I still have schooling and work to worry about. I'm sure I can optimize, slim down, and otherwise improve my workflow, and I'd love to just jump right into doing this full-time, cranking out LW videos every other week, but I can't. I've got a bit of a pipe dream, of course, that crowd-funding or an official sponsor could keep me going until Youtube add revenue/Subable/Patreon can support me, but I'm not confident there's room in people's budget for something like this work to become a priority for them.

Less of public interest, I have made a lot of progress with my schooling. This last spring I made an arrangement with my High school to do my Senior year somewhat differently than is standard. Thanks to advanced placement classes completed in previous years, I had only 3 credits needed to graduate, so I had the option to just do those 3 courses at my own pace, over the summer. 2 have been completed (yay me, I can self-motivate!) , and all I have left to finish is my English 12 class. 4 days ago, I buckled down and finished the 1st of the 4 papers I need to do. The reading needed for the others is getting done quickly, and I'm happy with what progress I have done already. I look forward finishing High School without having to actually go to school, and the validation of my previous feelings toward self-paced lessons is nice.

That's really great, and well done. I'm looking forward to the others, so I can send the complete set off to some of my friends - if I just send off this one, a few I know will say 'Yes Ben, the postmodernists are right."

Do you have someone to help you for future videos? I mean, just one other person to help you would probably cut down on mistakes like misspellings quite a bit.

It's a great idea and well executed, I hope you continue! (Even though I firmly disagree with the epistemology described in the post.) Please note that there are a few spelling mistakes (seperate, privilige), maybe you can fix those.
