Cope roundie
@histoire3 @silas yeah. I mean, I live in Europe myself and being an engineer I can see how round logs are just better durability-wise. But then, considering how many standards we have in Europe.... Ya know... π€£
BTW, I recently replaced all my sockets with UNEL ones - they cover most of the plugs
Yeah I need a lot of power.
No it's none of your business what I need it for...

@cjd @silas @ThatCrazyDude @histoire3 haarp?

@cjd @bonifartius @silas @histoire3 HARP - need even longer barrel and more propellant lol
IDK what that is but I'll take 2
@cjd @bonifartius @silas @histoire3 that was a DARPA (I think) project aiming to whip up a gun capable of sending a projectile to the goddamn orbit
There are so many problems out there that look harder than just scaling a T.T. Brown thruster...
@ThatCrazyDude @cjd @silas @histoire3 didn't some middle eastern country have had a project for this?
@bonifartius @cjd @silas @histoire3 yeah, if memory serves, Saddam was building something like that. And of course the Nazi Germany tried to build a gun to shell London on a cheap, but that apparently didn't go much past the prototype stage https://en.wikipedia.org/wiki/V-3_cannon

Germany did build their gun but it got raided pretty much immediately after normandy and put out of commission.
The engineer from the original HAARP project (Canadian I think) was pissed about it being cancelled and went looking for a new sponsor. Saddam was the only one interested so he agreed to build him a super-artillery gun as an alternative to SCUDs in exchange for Saddam financing his satellite launch device.
He got as far as designing and manufacturing barrel segments while working out of the netherlands before he got killed by totally-not-the-israelis-thats-a-hecking-conspiracy-theory-goy!.
The barrel segments were shipped to Iraq as oil production equipment but got intercepted and seized. And that was the end of the program.

Speaking of conspiracy theories I genuinely think space is being kept artificially expensive to limit access. Other simpler and cheaper launch options like rocketoons, air launches and cannon launches either get defunded early or only get used for side-projects like satellite killer missiles or space tourism.

All of that stuff doesn't work as well as you'd think, because you have to not just go UP a whole bunch, but you also have to accelerate to <insane speed> in order to get into an actual orbit so you won't just fall right back down.
An air launch from like the highest that a jet can fly reduces the rocket requirement by something like 5%, and in exchange for a lot more complexity.
Reactionless thrusters change the game though, and those probably have been suppressed...

Rocketoons are low speed, and can get you halfway to the karman line. Air resistance at 50km is a few percent of what it is at sea level, essentially it cuts out the entire first stage at the expense of making the launch much longer (no use for military applications, but fine for civil ones which make up the majority of launches). They are being increasingly used for sounding rockets and microsatellites. I strongly suspect they're an overlooked research direction.
Aircraft launches don't save *as* much but they're much more reusable than other first stage options.
Overall just from reading the development process for the shuttle it's pretty obvious that the mil-industrial complex can happily head down blind alleys for decades before they eventually correct. At the moment they're mostly centered on multi-stage solid fuel rockets but I'm not in the slightest convinced that's the best possible solution.

@cjd @silas @ThatCrazyDude @histoire3 while we're at exploding things, we all need explosively compressed magnetic flux generators
Isn't that how EMPs work? They charge a coil and then fire a magnet through it using a shotgun shell?
@cjd @bonifartius @silas @histoire3 nah, not quite. You're probably thinking about a gauss gun where you use a solenoid to accelerate a slug but that's pretty much proven to be just a cool toy by now. These days they use rail guns for that. Similar principle, but you can get way more power trough that. And EMP devices are totally different things - no projectiles there whatsoever, just the electromagnetic pulse that fries electronics and shiet

I thought they used some explosives to make enough magnetism fast enough...

@cjd @bonifartius @silas @histoire3 well, if we're talking nuclear EMP devices then yeah - I guess you could say it's explosives even though you'd tune your bomb to minimize the blast while maximizing the electron flux. Cyclotron radiation, you know.
@ThatCrazyDude @cjd @silas @histoire3 the explosive compressed flux generators can be used for emp, you compress the magnetic field lines to generate high currents. it's effectively a coil with explosives, shorting out windings from one end to the other
@bonifartius @cjd @silas @histoire3 I suppose you're right, but there are easier ways of generating pretty darn devastating EMP. All you need is a strong enough current source and piece a wire to short it. The moment the wire evaporates you get a super high amplitude square wave, because ya know, the cutoff, and you're frying what's unshielded and in the range.
@ThatCrazyDude @cjd @silas @histoire3 it's for generating high currents!
@ThatCrazyDude @cjd @silas @histoire3 i love shit like this because it's space age cartoon technology. feels like something a certain coyote would invent :)
@bonifartius @cjd @silas @histoire3 I use mine for HARP. Note only one A and look it up lol
It always amazes me how diverse the plugs/sockets are whenever I go to the continent, sometimes even within one country.
In Ireland we used the UK 3-Pin standard for almost everything (except specifically shavers for some reason) which doesn't have any downsides I can see. It won't actually deliver power until fully plugged in so it's hard to kill yourself by accident and the built in earth line is a good safety feature.
That said if we migrated to the three pin universal standard I wouldn't complain, it's more or less the same.

Low voltage so theyβre safe around water. Means you canβt put a plugged-in toaster in the bath.
Doesn't the earth pin already solve that problem though?
Plus aren't they 110v anyhow?

@Eiregoat @ThatCrazyDude @silas Youβre right, itβs not the voltage: they have a special isolation circuit.
The earth pin isnβt enough to save you if thereβs water involved, afaik.
@Eiregoat @ThatCrazyDude @silas Same reason the bathroom light switch is generally outside the room or a pull cord: keeping wet hands away from the mains.
I thought that was more because of spray, to avoid tripping the circuit with humidity.
If you have wet hands you're probably still going to use the light switch even if it's outside.

@Eiregoat @ThatCrazyDude @silas UK safety regs are arguably over-built.
It looks like (some?) modern plug sockets have something called Ground-Fault Circuit Interrupters built in, so toaster-in-the-bath is survivable in newer homes.
@Flick @Eiregoat @silas yeah, it's bonkers in the UK. I mean, having a law saying that every plug needs to have a built-in fuse is just ridiculous. But then, perhaps the Brits really need that level of idiot-proofing π€
In any case, one ground-fault breaker per phase combined with over current trip is more than enough to keep you from accidently electrocuting yourself ;)
@ThatCrazyDude @Flick @Eiregoat having fuses in the plug is not for human protection. its just the effect you get when designing your appliances with tiny shit cables, for a ringcircuit fused with 32A.

Ahh yes, that goofy thing that's unique to Britain. Like the goofy Edison Multi-wire Circuit that's unique to the US...
