Fridge Powered by Farts and Rainbows

The most difficult part of designing a durable, robust, long lasting refrigerator is dealing with the the question of how to power it.  Electricity is the answer most people would pop off before I get the last breath out.  But,

Designing a Refrigerator at 55mph

I have purpose.  Purpose is good. I’m building a refrigerator.  The question I get asked most often is, “Why don’t you just go buy a refrigerator?”.  They just don’t get it.  I understand that it is an unusual hobby, but

Beware of HVAC Technicians

In the fall of 2015, I did something which I felt was for my own good:  I quit my job as a local truck driver, and pursued a residential HVAC maintenance position at a Portland area company.  My view then,

Heat Pump or Heat Engine?

I haven’t bent any copper for a few weeks now.  Between the heat, a vacation, and some bad habits, the shop has barely been opened.  Part of the reason is due to a recent fascination with power plants.  Previously, in

The Power Plant -or- The Wood Fired Refrigerator

I don’t like heat pumps.  Wait, let me rephrase that:  I don’t like grid tied heat pumps.  It’s the electricity!  Heat pumps are an amazing technology which I am currently obsessed with, and I am in fact in the process

Ejectors in Refrigeration – an Expressor

Having developed a degree of confidence with copper brazing, and reaching the potential limits of what can be learned, I have decided to move past my original work with the Ebullator.  I document my progress with that device in Refrigeration

Sealing Thermocouples Into Refrigeration Lines

I thought I would provide some media to help describe my method of installing thermocouples into refrigeration lines.  I’ve found in working with the Ebullator, that the temperature readings I was getting by taping thermocouple tips to the outside of

Cannibalizing the Ebullator

I’ve moved on, in regards to what I think can be learned from the first flooded evaporator system, I have been calling “The Ebullator”.  Far too many limiting features were preventing me from moving on to the next step in
