That was a rabbit hole i did not need to spend the last 30 minutes on. For those who don't have the time like I didn't Organite is a substance made of resin metals and quartz that balances and harmonizes Bio-energy (known as orgone). Orgone is analogous to chi or prana and is a type of bio-energy that reverses the effect of entropy[0] It seems to be a mix of crystal healing and EMF grounding (also known as earthing)…

Try putting that rock in toxic water and drink it and we'll see what happens.

http://thewikireader.com/ update: https://www.indiegogo.com/projects/help-distribute-wikireade... I don't have one - my phone contains an offline wikipedia dump (including images), offline maps of the world including geological maps, medical manual, and my book collection, including things like http://the-knowledge.org/en-gb/ . I've got a vague plan to download the primitive technology youtube videos too.

So once "the end" comes, you'll be set for a good 4 hours before your phone runs out of battery?

You could recharge your phone using sticks (https://www.rei.com/product/115523/biolite-wood-burning-camp...) or a solar panel.

As it says in the article, we don't have anything to fear at the surface. Reversals have never been associated with increased extinction. When the field does reverse, it becomes increasingly disordered with higher-order moments dominating. If I recall, the dipole moment of Earth's magnetic field is normally over 90% of the strength. The higher-order moments dissipate faster, so it doesn't reach as far into space.

Given there are lots of species that use the Earth's magnetic field for navigation this is highly surprising. Perhaps there have been mass extinctions but they're not readily found, or our timings are wrong so they don't appear synchronised?

I wonder if there wouldn't be more seismic activity?

I'm stockpiling orgonite right now to protect my family. When the magnetic poles flip that stuff is going to be worth it's weight in gold!

"It is paradoxical, yet true, to say, that the more we know, the more ignorant we become in the absolute sense, for it is only through enlightenment that we become conscious of our limitations. Precisely one of the most gratifying results of intellectual evolution is the continuous opening up of new and greater prospects."

That would be surprising as the altitude control should be independent from the compass. I'd also wager that more than just the compass is used to determine course. Most likely a sanity check in the control software will kick in and return control to the pilot, just as if the compass(es) broke for some reason during flight.

Primary heading indication is the directional gyro[0] anyway. And magnetic flips don't happen "suddenly" in the timescale of a plane flight. [0] https://en.wikipedia.org/wiki/Heading_indicator

How fast are the flips. I've known about this effect for maybe a couple of decades, but never heard any theories on how fast the flip is.

If the flip is really slow, then that seems to lead to less human catastrophe, but more difficult perhaps for other species?

Sounds like this stuff would be amazing to put in my ham shack!

Yeah whoever made this site is bat-shit crazy. But there is tons of great information here. Anything from making soap the old fashioned way to brushed and brushless DC motors. Its really cool and wouldn't be the worst thing to have printed off and saved in a fallout shelter.

The site recommends building domes out of Sulphur. That doesn't seem like very good advice. As a non-expert in survival, I'd be wary of trusting anything written by a person with a creative interpretation of what's real and what isn't. You never know what else they're having unconventional opinions of.

Yeah, we don't want any unconventional ideas to slip through; cause that might lead to changes, and evolution and all sorts of scary shit.

Anyone that has messed with a Raspberry Pi will tell you that you don't want to hang the hopes of humanity being rebooted on a consumer-grade SD card. And since I'm nit-picking, any scenario necessitating the rebooting of civilization might very well involve something that fries SD cards and takes the silicon in your solar panel with it (nukes, big solar flare thingy). Boy Scout Field Guide and an Army survival manua…

Nukes and solar flares can be protected against: just seal your electronics in a good faraday cage. Putting them in an underground bunker in a lead-lined room should do it. Your paper books won't last as long: today's paper is acidic and falls apart within a century.

You can buy acid free archival paper that will last 500 years with careful storage. It costs ~3-5x as much, but is available.

I wonder what the longevity of something like that is. And for solar panels what do you do if it's a supervolcano that blocks out the sun? The real solution is a radioisotope thermoelectric generator which will give you a few hundred watts for decades. But I don't think they sell those online...

I think a rock that makes you immortal would be worth a hell of a lot more than its weight in gold..
