I am not a warrior.

Combine this with electroluminescent paint and you can get some really wild effects.

Interesting. I remember when I was in the Navy that we used red to preserve dark adapted vision but it made it hard to distinguish colors (white/red, blue/black tended to blend together). Areas that had multicolor indicators used blue light to allow the colors to be more easily separated and still maintain some dark…

Yeah, completely forgot about hi-res sonar. I was thinking more along the lines of photographic / structured light / laser scanning.

I wonder if anyone has made a 3-D scanner that works well under water.

You mean kind of like this?

Just what I was thinking. I wonder if the goblin shark is where they got the idea for that one.

Personally I like my Scottevest Expedition. Maybe not designed for all day in the 30's by itself but works well with a good flannel/fleece. Plus. it acts as my go bag. nothing else to carry.

Remember they are changing the name to end the joke.

I'd hope that today our top secret nuclear material is under a little better watch than it was in the 1940s.

Maybe not tracking asteroids (at least not until we start mining them). An argument can be made however that product safety can be a profitable point. These days companies fear the internet / social-media more than they fear gov't inspectors.

So it couldn't be pre-published data either, bummer. I suppose you could "Work in" from known areas but that would probably take considerable time and effort.

For a little perspective:

Is this a process that requires specialized knowledge/equipment (unpublicized GPS data/codes, data from other sources for comparison, massive computational power, etc.) or is it something you could do yourself with more publicly available knowledge/equipment?

What's really fascinating is some of the equipment used to lay and repair track these days. This is from Belgium.

This might be good for people doing maintenance on an existing trail, but the idea of taking the "path less followed" is to leave it the same way you found it.

Not as immense, but still awesome looking.

Those old cameras weren't exactly small or light. I wonder what they thought when someone suggested strapping one to the end of that rail?

Glad someone posted this. I was thinking that if they could make equipment to do the rebar/remesh laying they could pretty well automate the entire process.

It's a philosophical thing.
