Hey Kevin, network technician here. The reason you still had had fibre internet during the hurricane is likely because your fibre connection is using GPON, a passive, no electricity needed system. ADSL, VDSL and CATV copper-based networks need power to amplify, convert to fibre, split or modulate the signal from the phone exchange or CMTS to your house. your fibre is just all light being split and combined using optics and wizardry. even if a copper customer on the other connections had power at their house via generator, the street boxes, amplifiers, modulators, exchange etc would also need power along the way

Buying crude oil: It seeps out of the ground naturally in Los Angeles near the La Brea Tar Pits. The buildings in the area have a problem where it collects in their basements. So they have to pump it into storage tanks and transport it away. You could probably talk to a building owner or maintenance guy and get some. Or you could just go to the tar pits. There is a park where the oil just comes out randomly. Like watch where you step because there can be a oil puddle.

So, according to the van der waals gas model, to fit the same amount of helium inside a CO2 cartridge as there normally is CO2, you're going to need to pump it to 66 MPa. Which is would not require any crazy wall thickness, probably an inch of mild steel would already do the job, but you still have to get one hell of a powerful pump to overcome 66 MPa. And yet, this equation is merely a model, so expect the pressure to be slightly different. Converting it to psi, you get about 10,000 psi which, sure, is doable, but its probably gonna get really fucking expensive

I've not had to deal with this for a hot minute, so grain of salt: Fiberoptic cables are typically armored and depending on the technology used, don't need to have nearly as many repeaters installed. Copper lines need to have a repeater, usually at the end of a street or at the entrance to a development, and are susceptible to interference if the copper itself is exposed to liquid (Due to it interfering with signal integrity). Both sets are typically run underground. There was some discussion a few years ago about allowing ISPs to use telephone poles for internet lines (Common Carrier thing back in 2010s), but I'm not sure what the state of that is at this point.

I know someone suggested a PSI to achieve room temperature liquid helium, but I think it might be incorrect. From a cursory search, there is a 2017 paper in the Journal of Experimental and Theoretical Physics regarding experimental shock compression of helium into the 1+ TPa range (150+ million PSI) and it seems to suggest that helium goes from gas to plasma.
@watphodinner8164
@watphodinner8164 Жыл бұрын
To answer Will's questions: 1. How high should we pressurize Helium at room temp to liquefy it? The answer is n/a (there isn't a pressure high enough where you can liquefy Helium at room temp). This is because the critical temperature of Helium is 5.26 Kelvin (i.e. the max. temperature where liquid Helium can exist). Room temp is approx. 25 Celsius = 298 Kelvin, which is way above the critical temperature of Helium. Pressurizing Helium at room temp will only get you a supercritical fluid (i.e. a "gas-liquid hybrid" which is not a liquid, as what Nigel shared in his supercritical CO2 video: kzbin.info/www/bejne/gKTPqYOgp7Ktp7s). 2. How high of a pressure to get the same moles of Helium in a standard 16g CO2 cartridge? The answer is ~6500 psi which will blow up the CO2 cartridge as it holds CO2 only at ~900 psi. Using ideal gas law (we can do this since Helium compressibility factor -- i.e. measure of how far it deviates from ideal gas law -- is close to 1 even at high P) and taking the values (16g CO2 = 0.36 mol ; T = Room temp = 298 K ; V = 21 cm3 from various CO2 cartridge sellers), we get ~444 atm or ~6500 psi to get the same amount of Helium in moles of CO2. The 16g CO2 cartridge can hold ~900 psi of CO2, so we will blow up the cartridge if we fill it with the same amount of Helium in moles of CO2. 3. (Bonus) How many moles of Helium will we get to fill the CO2 cartridge without blowing it up? How many in grams? Less than one-seventh of the original moles of CO2 (~0.05 moles of Helium), or in terms of mass ~0.2g (i.e. less than 1% of CO2 mass in the same volume, temp, and pressure 😅) From (2), as 900 psi is approx. less than 1/7 of 6500 psi, and keeping everything else constant, using ideal gas law we can immediately see that 1/7 pressure -> 1/7 of moles or ~0.05 moles of Helium. Taking the molar mass of Helium, we can easily convert this back to the mass and obtain the ~0.2 g of Helium.

Putting liquid nitrogen in a steel container wouldn't work very well as a bomb (at least as a small one) because the gas could only expand at the speed of sound and it would cool as it expanded, which would reduce how hard it's pushing the steel pieces apart. Not only do the explosives in bombs expand WAY faster than the speed of sound (RDX detonates at Mach 24 for instance) but also the rate of acceleration, called brisance, give high explosives breaking power, that helps to fragment the metal casing. And Nigel is right. Helium has no liquid phase at room temperature, no matter how high the pressure gets.

Nigel listed the critcal temp, but didn't mention the critical pressure of 2.2 bar, above both, helium is going to be supercritcal when bought in a tank. inreasing the pressure does increase the dencity (mostly) linearly, but thicker walls give deminishing returns in terms of max load vs mass of tank

so the thing with phase diagrams there are first and second order phase transitions, first order is the normal one you think of which is a discrete change from one phase to another like water freezing or boiling. first order transitions are lines on the phase diagram of temperature vs pressure that separates the two phases. a critical point is when one of those lines just ends in the middle of a phase diagram. because the line ends you can go from one phase to another without crossing the line, by going around the critical point. this is a second order phase transition because where you start and end are regular gas/liquid phases but you have to somehow continuously transition between them, ie pass through a supercritical fluid phase. the critical point is a particular temperature AND pressure, not just a temperature. just look the phase diagrams, there are different paths through the 2D phase diagram by changing temp and pressure and you cant always just substitute low temperature with high pressure

I haven't seen the answer in these comments but this seems to be the answer At normal atmospheric pressure helium does not solidify. At 25 atmospheres of pressure helium is a solid at 0.95 K. Helium can be made solid at room temperature if the pressure rises to about 114 thousand atmospheres: that is a pressure of 1.67 million psi, or 834 tons per square inch.

I don't know if Kevin knows this fact and that's why he brought it up, but using nuclear bombs is actually a legitimate way to stop natural gas leaks. What you do is drill a hole next to the source leak pipe, lower a nuclear bomb to a specific depth, then detonate it. The shockwave it creates underground will collapse the leaking pipe, thus sealing it, and the wind blast it transmits to the surface can also blow out any burning natural gas fires. To answer the question of why can't we nuke cyclones/typhoons/hurricanes, it's because they are just way too damn powerful. The energy of these storms are measured by the energy released in nuclear detonations. I've heard that one of the US east coast's hurricane has more energy than every single nuclear weapon on earth. So you can't just blow it out with a nuclear bomb, it's like blowing out a forest fire with a leave blower.

Fibre lines are in fact underground, beside being more weather resistant it also prevents the light from blinding everyone nearby if the cable breaks. This is why you need to be really careful not to hit a line when digging a hole as you will go blind and won't know until a few days later when your vision starts to go. It's also not on the visible spectrum you you can't tell anything even happened

In my area the fiber lines are strung on telephone poles along with the cable lines. They're not going to blind you unless you stare directly into them at close range.

@@ZanHecht these are probably really specific cables, hanging them on poles gets super expensive and they have to be maintained especially in winter. It's probably lower power local lines or something that needs to be accessed regularly. Also don't encourage carelessness for something you haven't worked with. A fracture in a high power cable can be dangerous up to 15 or 20 feet away. Plenty far enough to be dangerous to someone who has no idea what's going on, though most modern cables are being installed with a system to automatically shut them off now some still don't and you should be careful

There is no actual phase Chang occurring with a supercritical fluid. Below the critical point energy will be absorbed as the gas liquifies, and there will be a liquid and gas layer. If you just compress the gas, it’ll eventually get to the same density as the liquid would be, but it’s still just a gas with an insanely high density. Applied science has some awesome videos showing off co2 as it’s heated past the critical point where the density of gas and liquid is the same, and the boundary just disappears
