The graph shows the temperature in the chicken coop, the temperature of the air in the vent pipe coming from the biomeiler, and the temperature of the outdoor air. The electrical energy usage is shown for any days when the electric heater was used. The scale is the same, but the units are in kWh. […]

During the week, I was tidying up my application for the Arctic Innovation Competition. I slightly improved the 3-D printed components by adding another hole to the face. The prototype now works well enough to demonstrate the working concept and I began taking pictures of it in use. This morning, I finished taking pictures and

While I was preparing my breakfast on Tuesday, I saw this fellow sitting on the far side of the yard. He was back, again, this morning. This is probably a snowshoe hare. We also have cottontail rabbits, feral rabbits, and hybrids in the area. In the southwest of the state, there are Alaska hares,

Yesterday, Melissa and I drove to Delta Junction to attend the Delta Farm Forum. This event is held annually to give the local farmers a venue to hear presentations on topics of interest in that area. Delta Junction is one of the agricultural centers of Alaska. Delta barley is well-known throughout the state, but there
It has been some time since the last post because I have been occupied preparing an entry for the 2025 Arctic Innovation Competition. This competition is annually held in Fairbanks to encourage and recognize creative ideas for new products or solutions. The innovations don’t have to be related to the arctic, but that was the

While running the compressor to aerate the biomeiler pile, I noticed that the back pressure was unusually high; about 30 psi. Typically, the gauge reads about 5 psi. Yesterday, the reading was about 12 psi, but that wasn’t unusual enough to catch my attention. I looked for kinks in the hose, but found none. My
We have recently seen the temperatures rising and falling, which often has the effect of loosening water molecules from the snow in sunny areas and allowing them to drift freely during the day. If outdoor objects are colder than the air and water molecules collide with them, the molecules stick to the objects and a
The temperatures in the biomeiler pile are measured with thermocouples buried in several locations. Nine of them are found at three heights (1’, 2’, and 3’ above the ground) in the inner core, outer core, and mantle of the pile. The graph shown in today’s post shows the temperatures measured by thermocouples at 3’ height.

Fairbanks is located in the Tanana Valley in the interior of Alaska. During the winter months it is often the case that cold air is trapped at ground level and a warmer layer of air lies overhead. Air temperatures increase with altitude, which is the opposite of the normal condition. This situation is called an
The graph shows the temperature in the chicken coop, the temperature of the air in the vent pipe coming from the biomeiler, and the temperature of the outdoor air. On the same graph, I added the electrical energy usage for the days when I had to use the electric heater. The scale is the same,
