I built a vacuum assisted bottle filling mechanism!" 😂 [41 likes] @ChadLaFarge: For clarity, Eutectic is not to do with "salt"... A eutectic mixture or system is a specific combination of two or more substances that melts and freezes at a single, lower temperature than any of its separate components. For example, i love work with eutectic solder... beautiful fillet every time, because it turns solid very quickly when heat is removed. [39 likes] @LoganKearsley: "Eutectic" is not a fancy name for "salt solution". It's a fancy name for a solution with component ratios that minimize the freezing point, regardless of whether or not one of the components is a salt. [37 likes] @StormEyeB: NightHawkinLight made a video a while back with a good example of a eutectic mixture with a freezing point above water, (around 16C, 61F) and lists practical applications for it when you need something cool but not necessarily freezing over several hours. I made a few myself and they're incredible for keeping cool in hot weather or as a cooling pack for injuries that doesn't need to be constantly replaced and doesn't get painfully cold. It'll be interesting to see what kind of solution yours will be and what applications it'll be useful for. [35 likes] @TechIngredients: Understood. However, the mix won't even pass through the large entrance to the funnel. Speeding up the stick and funnel approach won't hurt, but the vacuum is critical if filling hundreds of bottles. [29 likes] @bald_chicken: You’re trying to make high temp phase shifting material powered AC. That material will freeze at night or underground and play the role of the heat exchanger. Fully passive heat pump. NightHawkInLight was and probably is working on something similar. You guys should collaborate, both of you are great. [17 likes] @barthanes1: Or you could just use a piping bag to squeeze the mixture into the bottle. Fill a resealable bag with the mixture, cut off the corner, and squeeze it in. It would maybe only be a little slower than your vacuum filling apparatus, but it would be a lot cheaper.

Pre freeze them then they should help keep the thing cold while using less power (especially good for ones with a battery) without losing a lot of internal space.

They use graphite in those to increase thermal conductivity from the HDPE pipes to the surrounding earth. Graphite may be better than macro CF pieces.

We call it salmiak (from the old name sal ammoniac) and we make a candy called salty licorice with it. 😋 [6 likes] @greggeiger5203: Great video once again. I went through a similar process last year when I was looking into making my own large freezer packs. I looked into & tested a few eutectic mixtures, but stopped going that direction when I found out how much they reduce the specific heat compared to pure water ice. I understand this isn’t as much of an issue in your current project, but it would’ve been neat to hear you speak about this part of the equation. I’d be interested in seeing that graph extended to see how much longer it took for the solid ice to melt compared to your eutectic mixture. FWIW, I ultimately found that large containers of ice worked best for my use case, which was keeping a cooler near refrigerator temps for the longest amount of time. [6 likes] @sanphir3: Amazing, I can't believe what a scam icepack gels are, when this seems so simple. I'm off to build a bunch for my cooler and to help bulk the freezer against power outages. [3 likes] @AlRoderick: You can make a custom funnel by sacrificing one of your sports drink bottles, just cut off the wide end. Then you make a fitting to fit two bottles together by the threads by gluing two caps together and drilling out the middle. [3 likes] @GOGx72r9: When adding the solution to the bottle would it be a good idea to use a ziplock bag with a corner cut like a frosting bag? 23:55 [1 likes] @szogun1987: ​ @phraust17 I tried to make glowing cider, it didn't glow but had %%%. From nighthawks examples I copied wosh rocket. Not much but something. I'm quite sure I would never replicate anything from integza or plasma channel [0 likes] @bukszpryt_: @Peter_Schluss-Mit-Lustig I've seen some of his videos, but when he started 3d printing turbines for tiny air/water generators, he was doing pretty much only this. [0 likes] @GabberDenGode: @TechIngredients Piping bags are great for filling viscous liquids into bottles. It's a very common technique in professional kitchens [0 likes] @karlwollan9769: This reminded me of the "thermos flask" heat extraction system incorporated by Saab cars in the late nineties. Basically it was an engine bay mounted insulated water container lined with a special salt hooked up to the cooling water system aided by a 12 volt pump. In winterfrozen Scandinavia, start the pump some 20 minutes before the engine and hey presto, no more cold-start! [0 likes] @MrTurbo_: i was thinking throughout the entire video "now neat would it be to have something which freezes at 21 degrees Celsius, so you could make a really large reservoir underground, and run some copper pipe through it, and then connect that to a indoors radiator, so in the summer it cools down your house to 21 degrees, while in the winter it heats up your house to 21 degrees" then hearing the end of the video made me quite exited, looking forward to the next video :) [0 likes] @typeer: Feels like just watched something important to the history of technology, use of eutectic solution thermal masses gonna experience a renaissance soon here [0 likes] @phlogistanjones2722: Thank you sir. That absolute *BEST* forty minutes of my week. As with *many* DIY projects if you spend a few bucks or hundreds of bucks you can construct or purchase specialty tools that in short order save you several multiples of their cost. I am reminded of a Will Prowse video that showed you from soup-to-nuts installation of a minisplit your own self. Purchasing an uncharged unit, the vacuum pump, gauges, special tools and sufficient fittings, refrigerant, scale etc the overall cost was *STILL* less than *HALF* of what a single installed unit would cost. Learning the techniques and doing the work your own self might take a few hours the first time but if you could then install additional units later since the tools are already purchased and you still have the knowledge so you end up with the cost of the uncharged unit, a few additional fittings perhaps and some refrigerant.
