As a material scientist, I'm reminded of a joke from college which has changed only a little: What's the only thing graphene (used to be carbon nanotubes) can't do? A: Leave the lab

I interviewed at SpaceX a few years back and can roundly confirm that everybody I interviewed with, barring a VP, had what I'd call "the fear" in their eyes - I ended up not getting an offer based on my lackluster college GPA

That's fairly poor locating there - either they were using a paper map or using a radiodetection line locator and the operator wasn't very good or the line/tracer wire was electrically continuous with another nearby structure

There are a number of outfits offering various takes - these Q-Cabins are popular in some areas of CO and CA, and come in similar kit fashion without being log homes. Link: http://theqcabin.com/

I’d recommend giving them a shot - I honestly feel way better after rebreather deco than OC. Portable gas blending is awesome. If you’re using a rebreather properly and have sufficient bailout, they’re pretty reliable these days. You can sw

You’re doing high percentage trimix deco dives and still see rebreathers as dangerous?

Nope, just part of the premise - you're good to go!

Rescue teams for caves are usually regional volunteer groups - and usually it's body recovery. They go into it knowing what they're likely to find - very rarely (if ever) are they first responders or typical public service employe

There are also a number of facebook groups for accident discussion, analysis, and learning that are kept pretty civil and are usually good resources. There's some pretty interesting chatter about this incident in them right now. Turns

A lot of us cave divers work in other areas as well - I'm an engineer in Oil & Gas - a lot of other folks I know are either scientists or engineers. This sort of activity appeals to us for some reason. You described a blowout prev

With the proper training and experience, this is an academically rewarding sport / hobby, and is quite safe - still less so than normal open water diving but not the death trap that it seems. The NSS-CDS ( http://nsscds.org

When you're learning to cave dive, one of the first things that you learn is that you may very well die in there. Most of the training focuses on systems, skills repetition, and understanding and using redundant systems - folks getting

Some divers carry a few odds and ends in their buttpacks for longer duration dives, but you never factor this sort of stay into a plan, and don't want to take unnecessary equipment or kit in with you. Where there's been a lot of

The nylon lines are only a safety system - there's typically a mainline and then only branches off of it. The only time multiple lines are used are at the entrance (the mainline is usually placed 50-100m back to prevent untrained dive

It creates a voltage gradient radiating out from the contact point. A gradient of more than 15VAC/m is generally bad news. The resistance can be enough to prevent automatic circuit protections from tripping as well if there's no

Are there any metrics on how many Larry Wildmans (Wildmen?) are engaged with the site already, and how many new corporations have been formed? And any challenges yet to anti-poaching clauses?

At that length I'd be surprised if they didn't - caustic & acid will require a few line flushes etc, whereas a plastic cleaning pig can be run with the beer in line without quality issues provided they run it every few days.

Hot Tapping ( https://en.wikipedia.org/wiki/Hot_tapping ) is actually really easy on poly line - and given the non-hazardous nature of beer I'm guessing they have little to no flow control on the line either. It so

The wave gliders are some awesome technology - I've been keeping an eye on their development for a while. Unfortunately they've only been hiring out of a very small pool and it's about impossible to get your foot in the door
