Thanks! Let's see if we can change that.

[@mustwereallydothis]

Michael, we really can change that. You would be amazed by how much of an impact the concerted effort of just a few people can make. First, turn on notifications so you can view new videos as soon as possible after they go live. Then, make a bunch of comments designed to elicit responses from other viewers. Questions seem to work best in my experience, though there are plenty of others that also work. Finally, reply to comments made by others. The algorithm LOVES engagement and tends to push videos that have more to new viewers. That's why it's never a good idea to comment on videos that you feel are inappropriate. I hate to say it, but shorts are almost a necessity these days if you hope to grow your viewership. People scroll through dozens of shorts in a sitting. There's no need for them to decide to click on a thumbnail, and they usually don't mind spending 30 seconds to a minute watching a video from a channel they've never heard of. When they happen upon a short that interests them, they can and often do, visit your full channel with just two clicks. We had to abandon our channel shortly after we began due to a tragic accident, but I did a ton of research prior to that point. Now I have all this knowledge that I have no personal use for, so I've turned it into a hobby of sorts. If you decide to produce shorts, I would be more than happy to give you a few pointers on how to make the best use of them.

2 things: 1. Maybe it would make more sense to fashion a reflector and shine the light in from outside the chamber to get rid of any conduction across the chamber 2.

I was just thinking as the pressure dropped the battery pack inflated and as it popped any volatile would spray. Maybe not so much from the plywood but as anything even micro bubbled onto the surface it would have some added energy and droplets surely travel further in vacuum. By the time the pressure had dropped there would be little to no airflow in any direction beyond the spray direction of the popping battery.

A couple of things: - monitor that wood over time and see how much water it reabsorbs. I think you’ll find in a humid environment the more porous wood regains more water weight. - you definitely coated those items with vaporized metal. You see evidence on the back wall, and you see differences in color and tone on the potato closer to the lamp. Re-running this with some way to shield from that ionized metal vapor might yield tastier outputs. You definitely came up with a new and interesting variant on the food dehydrator.

I've worked High Vacuum for almost 30 years (nanotorr scale) and never heard it expressed as microns, only millitorr. They're essentially the same, I learned something in addition to the experiment. Pretty neat!

[@grn1]

After a quick web search it seems like millitorr is mostly used for scientific research but is otherwise uncommon though I'm sure location and time period play some role in how common one measurement is compared to another.

[@Phytologics]

I've worked in mass spectroscopy, which uses high vacuum systems for almost 30 years so I know microns well because roughing pumps, like a rotary vane or scroll pump, are measured with those units. It's very useful to think of microns as 10E-3 torr (or millitorr) since, once you add a turbo or oil diffusion pump you can get to 10E-6 to 10E-8 torr or a titanium sublimation pump will go down to 10E-9 torr. Knowing the equivalence you can keep all the units as torr or just skip that nonsense and use millibar.

[@DagarothBlackrose]

@@Phytologics I work in semiconductor manufacturing, we're pretty much exclusively SI units. Torr is the only exception, for some odd reason, probably because its almost 1:1 with microns. Cryopumps tend to be used in deposition tools, and turbos in etch tools, with a few exceptions for volatile gasses. We don't use diff pumps due to oil contamination. Pretty neat to talk to someone in an industry that uses diffs though. I've seen about every type of pump out there EXCEPT a diff because of the equipment I work on.

[@Tonyneg]

Just to point out, while it works both ways, that cold trap is backwards. If you are pulling vacuum through the internal tube side, and you actually capture a ton of liquid, it’ll suck up that tube. The tube is to direct the vapors to the coldest part of the trap, then the outlet sits we’ll above so you never suck any liquid into the pump

[@fiery_transition]

Open fibrous fruits or vegetables suspended in a tasty liquid, be it alcohol or just something good for the combination, and then pull the vacuum, see if you can infuse the food with flavor. Also, food grade wood in a liquid and using the result for fermentation as an additive in the process or smoking foods would be interesting.

[@Culpride]

Alcohol would evaporate even faster than the water and boil at room temperature in the vacuum. You would have to use a high pressure chamber to push liquids inside vegetables ... then maybe freese them in the high pressure state, put them still frozen into vacuum to freesedry the solid flavors ... But since most nice flavors boil away at low pressures 🤷‍♂

[@MrMakulit1959]

That was very cool. I like the idea of making a aerogel/wood material, especially since wood strength to weight is actually very good. Woodworking is an old and well practiced human skill. If the vacuum treated wood could be treated/coated so that it won't take up water again, maybe you really could make wooden spaceships. Resins are relatively weak, and heavy. Lithium Magnesium alloy however has a yield strength similar to mild steel, and a sp.gravity of about 1.35-1.4 . melting temp from 190°C to 230°C. If the vacuum treated wood were dipped? sputtered? electocoated? with Lithium Magnesium alloy sufficient to keep water vapor from re-entering the wood, you might end up with s very strong, very lightweight material. Just a thought. Thanks for your thought provoking work.

With a few changes such as a higher pressure setting, no light source, large water trap, and heated sample tray you could freeze dry food. Sliced strawberries would be great test. Commercial freeze dryers have heated trays and large refrigerated water traps. A small silicon rubber heating pad would work nicely to keep the strawberries from actually freezing as the water is removed.

I'm interested in how strong the wood pieces are having been "vacuumed" and if they have gained any weight back from absorption of water (and if that affects strength)

You should test your extremely white/ reflective paint inside this chamber. Quite curious to see how well it would work. Could be nice to get information on how much it heats up, as it can only reflect radiations or radiate heat ; and not conduct it to a gas like it does in an atmosphere. Nice thing is you could tie how much watts the bulb uses to how much the painted material heats up for a give mass and surface. That way you can really appreciate the effeciency of your paint. If it heats up by X degrees for Y mass, then it must have reflected Z watts. Maybe compare it to a multi-layer insulation for a "standard".

I recall a problem one of the space missions had (can't remember which one) where an access door became jamed. Turns out, if you put two pieces of metal together, here on earth, the thing that prevents them fuzing together is the air that gets trapped between them. In the vacuum of space, however, the separate metal parts of the hinges of the door just fuzed together. We get the same effect if we "wring" guage blocks together. If you leave them together for too long you can never separate them. So something you might try is putting a couple of pieces of metal together and leaving them 24hours in your vacuum. Can you actually weld metal simply by using a vacuum? In theory you should be able to.

[@cartmanrlsusall]

@@Hephera We know that the wood dried out. The question is did the water contribute to the strength of the wood, or more precisely, _how much_ did the water contribute?

[@BjornV78]

@@Pystro , i think you have to consider the wood as a sponge, is a dry sponge stronger or not then a sponge that is soaked with water ? If you hit the soaked sponge quick enough with a sheet of wood or metal,the water need some time to escape, so the impact will be harder compared to a dry sponge, but if hit the soaked sponge very slow , the impact is almost the same compared to a dry sponge. So i think that the water does not contribute to the strenght of the wood. On the otherhand, the more water in wood, the more flexible wood can be if you bent it without breaking it, this also how wood is intensional curved and bent for making round objects in wood by steaming the wood, bent or curved it, and let it dry out in this shape. Once dry out, the wood is as strong as before. Grtz

It should normalize to the average humidity in surrounding area. I say that from my experience with wood based instruments, ie guitars .

[@noodlelynoodle.]

I'd imagine it would end up being a lot more brittle cause the weight loss is water loss and really overly dry wood is prone to cracking most dried lumber still has like 20% moisture content in it with stuff from places like home Depot being able to be even higher cause they don't properly dry it. I got 2 4x4s there the other day and one felt almost twice as heavy cause it was noticeably damp. Like stuff that's dried out really slowly over time like old beams for buildings is super sought after but it seems when wood is dried really quickly from like direct sunlight it's more prone to cracking during that process it seems cause it expands and contracts depending on the moisture level so drying it too quickly would impart strain on the wood as it's trying to shrink way faster causing cracks which I feel would happen with vacuum dried wood since it's a lot faster process than standard wood drying methods

Does the UV and radiation light do anything to the wood that would happen when one make charcoal?
