I first used Internet sometime around 1994 or 1995; it was at an education fair and there were some computers available to the public with a network connection. They had a pre-loaded website linking to educational networks around the globe and I surfed the web and clicked on the website from an Australian university… and it was just mind-blowing. I knew of networks and “internet” but connecting to a computer half globe away was awe inspiring.
As for interacting to people, that didn’t happen until 2002 and I have no idea what it was.
I interacted with internet in school, and it was info site that still exists today. In 199somethings, i dont remember when exactly, but just before 2000. What did I feel? It was sort of like being in a library, but where every book was readily available, also software was pirated and nobody really cared about punishing pirates. People published a lot of comic books online which I liked very much and I did read a lot of them.
I’ve been playing D2:R again. I’m playing softcore mode with ladder ranking enabled. I’m almost among the top 1 million players. As a class only ranking, I’m 277.000th. But the game’s been going on since september 2021, iirc. Also I need to say that it takes more experience points and time to go through levels 95 to 99 than it is between levels 1-90.
Beddy time again, but tonight I have a video to share. Nighties lovelies!
Also: here comes Grady with another cool engineering video…
It’s shocking how fast does magnesium corrode, and it just does not do much a better job than aluminum and zinc. Guess that zinc might be the default sacrifical cathode with aluminum used in special cases…
(And, how about using a piece of zinc or aluminum attached to your car body to protect it from corrosion…? It should work, probably…)
There will be robot workers if we can get them to reproduce themselves. Creating everything from scratch is too troublesome. We have to make them evolve too.
There is no real way to put out such fire, only chance is to drench it in water until the remaining elements are too cold to burn. It’s a lengthy process. Fire extinguishers do nothing because it’s not a combustion, it’s an exothermic reaction where lithium crystals decompose and release heat and hot gasses without oxygen.
Probably I would have tried throwing the battery pack into a bucket of water and keep adding water until the fire stopped…
And now I’m off to bed. nighties lovelies!
Also: it’s scary, it’s scientific, and it’s entertaining. Great video.
Lithium fires (which are a metal fire) should be treated with a powder extinguisher (class D). Don’t ever attempt to use water, the fire will get worse up to the point where an explosion may result, spreading the fire even further, because this type of metal actually reacts with water exothermally (remember those small demonstrations with sodium in your chemistry class ?). In an emergency where you don’t have a class D extinguisher, use kitchen salt, sand or even dirt if you can reach the source of the flames. Smother it.
Maybe we could use a chemical that could combine with lithium and extinguish it in some way, stopping reaction that makes it so violently burning. And then equip batteries in covering containing it. Selfextinguishing batteries.
I may be too optimistic, but it seems the agent would have to be close to the lithium, maybe inside battery covering to stop lithium in the beginning, for cost of battery not functioning anymore when it happens, there could be bloating probably and maybe some gas escaping, but preventing very high temperature that would really mess things up. Obviously that would also make batteries heavier.
Some of the type D extinguishers use a form of graphite powder, which is lightweight and can be immobilized in a polymer carrier of course. There’s definitely potential in that idea of yours A nice little engineering problem.
A nice little engineering problem.
