Carbon Monoxide!?

Weird. The smoke alarm went off, not incredibly odd when I am using the fireplace, but it wasn't the smoke detector. It was the CO alarm. I was totally surprised. It had never gone off as long as I have had one, over many many years. Yep, after resetting it a few times. It was getting a reading over 200 ppm CO. When I took it downstairs I got a reading near 300 ppm. I started getting light headed at this point. After thinking maybe the furnace heat exchanger failed and puzzling around a bit I figured out what happened. As part of the huge winter storm that recently covered almost half of the US, we lost our electricity. So, being well prepared, I rolled out the generator and started doing what I normally do. The generator (although it was completely outside) was creating CO to get in the house. Using the fireplace draft (and possibly other leaks) the whole house created a vacuum around the seal of the basement garage door. After the CO got into the house the forced air heat...

VLJs --- 20 years after all the hype

-

20 years ago the world was abuzz with the VLJ (very light jet) movement. I got to park next to this one the other day in South Carolina. Here is an article from Wired magazine from 14 years ago indicating the demise (or morph) of the hyped VLJ. (Wired article from 2009). The plane in the picture is the Cirrus Vision jet. It probably won the contest in actually (mostly) delivering on the promise of a VLJ. The actual cost of the plane here (about 3 million USD) is way outside what the ridiculously low projected pricing of 20 years ago. But, the plane is cool for sure and is very relateable to the Cirrus piston aircraft. The cruise speed of the vison jet is 345 mph. The Honda jet cruises at 424 mph and the Phenom jet at 466 mph. The speed of the vision jet is incredible compared to my Cessna 172 at 140 mph, but the Vision jet speed is pretty much with the turboprops. (King Air 360 mph and the PC-12 at 311 mph).

My kayak trip was awesome! So what happens when three restless boys want to do something exciting in Atlanta over the Thanksgiving holiday? Shoot the Hooch. Traverse the Chattahoochee river in grand style. We did it in a combination of couchsurfer, thrillseeker, and urban explorer (mostly Couchsurfer). We met for the first time last week. The participants, one from France (a recent MBA grad from Georgia Tech), one from California (a 20 something Mechanical Engineer) and me. We put in at the Buford Dam at Lake Lanier. We put in illegally since the park was closed. (I mean who would want to use a park on a holiday?) We parked illegally at both ends of the run (not sure of the reasons, but an accumulation of a $50 parking ticket). And, we camped illegally for two nights. So, let's add some danger with two beginner kayakers, and very fast water. It is very dangerous, at least one person has died in the Chattahoochee in the last year from swift water. The risks were fully assessed. This...

It is 10 below zero this evening. it is beautiful outside as you look at the stars and the far off view of the city and its vapor. I have fashioned a muffin fan on the intake of the coal stove to boost heat output. We have to be careful not to overheat the stove and cause warping of the critical pieces. I will be making a more permanent system with feedback (of course) at some point. I heard an inspirational speech at toastmasters today. That is what has kept me going with the organization. I like that. Growth. We don't know where growth takes us. Picture yourself on the end of a sapling. We are warm and the diesel is plugged in.
