I saw a local agency demo their use of the pirate box for Wildland firefighting. They had a GIS team working on mapping updates to fire lines, cut lines, dozer paths, crew assignments, etc. And as required they'd upload everything to t

The manufacturing of H2 from CH4 is one thing that really bothers me about the whole concept. We have CH4 cars today, and an infrastructure in place. It should be expanded and tbh it's a great fuel. The leakages are a problem but I thi

Exactly. The old ones were basically passive cleaners. The modern ones are full on inspection tools with cameras, magnometers, etc. We have a natural gas line running through one of our agency properties, and it was recently repaired due to

Yeah his practical engineering is excellent as well.

Pretty cool! One thing that fascinated me working for a sanitation district was that we had some huge pumping stations like this, but hiding in plain sight. There would be a metal vault cover in the sidewalk, it opens up to a stairwell, the

Any time! I enjoyed the work, and I also got to work on closed sites which always made for pretty fun days as one was an isolated area and another was a golf course.

And in the US we have plenty of open land to place them. I understand places like Japan wanting to find alternative means

It might even be sooner than that. Once oil gets too expensive to pull out the the ground, mining plastic from landfills and decomposing it back to the hydrocarbons might end up big business. The natural gas/ ch4 production follows a p

It wasn't so much the substances, more the moisture. A wet environment is much better for ch4 generation (was my understanding). So we had an area that we called "the galleries" where we would rotate injecting the leachate. T

I really enjoyed my time working at a medium sized landfill as their surveyor and civil tech. The engineering discussion in the article is spot on. We chose to reinject most of our leachate as that helps with CH4 production, and more CH4 fo

We do the same concept in night diving. Set a glow stick with a pie tin low, and another high behind and above it. Then when you come up from the dive you can see which way you need to swim along shore to exit where you entered.

Thank you for your response. I did get my novice license (or whatever the lowest license is called) but never got an old borrowed radio to actually transmit. Then life kind of got in the way. I keep meaning to get back into it, the sstv and

Does one have to take a test for renewal? Or is it a one and done type thing?

Not if they buy an off-the-shelf solution.

Not GP but modern GPS / GNSS manufacturers intentionally do not allow their devices to function over some speed (1000 mph or something like that). So they won't work on warheads as part of a guidance system.

Mine are the used car dealers that have every make and model ever created (or maybe just the 1500 most popular) in every description. On cars that aren't even close. So even if you're looking for a 1999 Honda Civic, every car for

Basically yeah, it take legislation. Like the Civil rights act immediately struck down all of the racist covenants (that still exist but are unenforceable). So maybe a municipal action could do something similar? Of course the easiest way t

>It's a dry reading that can be fascinating at the same time. I'm a surveyor by trade and you hit the nail on the head. One of my favorite parts about this stuff is the history, and how we humans have tried to understand the sh

Yep the monuments on the plates here in USA have actual published velocities. Which means yo can model what the coordinates should be after some previous survey and go check them. Pretty cool!

Surveyors reference monuments on the ground. Since tectonic plates tend to move together then so so short lines and their corners. It can get complicated on large tracts or lengths, but stuff like rail roads and freeways are composed of man

It's based on a center of mass point of the earth. The system is an example of an "ECEF" or Earth Centered Earth Fixed system. Good writeup here - https://en.m.wikipedia.org/wiki/Earth-centered,_Earth-fix
