I am looking at solar systems for domestic hot water. It appears the best way is to buy a Rheem/ruud (model 81V080HE1) 80 gallon water heater (electric). That water heater has a built in heat exchanger for a solar panel system. Then you use zone pumps, valves and thermostats normally used for radient heating but in reverse. That way I can have a zone that heats water from the coal stove if on, or the solar panels, if hot, or another source. Maybe the llamas give off heat...biomass.

It's Wednesday. Halfway mark. We are super busy at work. We have a big event down in florida 3rd week in March. It is our International Dealer Meeting. We have it every 2 years. This year I am going. I have a booth for technical publications. Everyone seems to be working on the event in marketing.

I am back from a speaking engagement at a familiar conference (CIDM) in San Jose California. Afterwards, I met Angie at the ATL airport and headed to the farm and to see my cousins, Aunt and Sister (and my newest relative) in Baltimore and Washington DC. It was a densely scheduled trip, but nothing compared to our typical overseas vacation trips. I have been having educational fun with my recent birthday gift. It is a Radiacode 103. It is a very sensitive scintillation radiation detector. Loads of fun. The 1k µS/hr spike shown is what the carry on baggage x-ray machine doses out. I am glad I wasn't inside the x-ray equipment. Stopping at some antique stores along the way, I found a number of uranium glass pieces. Yes, they are radioactive. Yes, the dose is comparable to that you get from riding in a commercial airplane. I took a couple of pics of property in Upstate NY. Unbelievable. It will beat out images of the best trailer trash anywhere. And yes, the vehicles are systemica...

Busy and Busier

It has been busy and somewhat stressful. I am reflecting on the comparatively relative low stress of traveling alone in Southern Africa last year at about this time. I mean in Africa, I only had to worry about getting in car accidents (maybe running someone over), missing flights, getting robbed or attacked. All of these possibilities in a very unfamiliar land. Now interestingly, I seem to have more stress -- over what? It is probably a very good example of good stress versus bad stress. Good stress comes from calculated self-directed challenge. Bad stress comes from captivity and what we feel we "should" be doing. "Should" indicates there are external forces we are beholden to --without our own devices or agency. In April, I am speaking at CIDM Convex in San Jose CA. https://convex.infomanagementcenter.com/ . I also learned I am speaking at LavaCon in October https://www.lavacon.org/ . There were 150 speakers considered and only 40 selected. It will be my first t...

The Electromagnetic Spectrum --DC to Daylight (and actually well beyond)

Besides carrying my scintillation detector with me looking for ionizing radiation (over 2.46 petahertz) and decaying isotopes, I have been playing in the more friendly "basement" of the electromagnetic spectrum (under a gigahertz). A pic of my radio bench. I sold my IFR ( http://blog.theguysatwork.com/2025/02/updates-storm-and-other.html) . I needed to replace the function (at least a lot of it) with a cheaper digital produt. So for 1/10 the sale price of my IFR, I ended up buying a TinySA Ultra+ ZS406 Spectrum Analyzer. It is indeed tiny. It does what I want it to do and it's a fun new toy. Our autographed copy of the "Fall of Civilizations" arrived from the UK. Paul Cooper does such a great job with his pobcasts and videos. I felt compelled to get a personalized copy of the book. ( https://www.paulmmcooper.com/ ) Seeing this licence plate on the front of a pickup truck seemed fitting-- not so much as contrarian, but as a Komatsu equipment fan. It's g...
