Who’d Build a Refrigerator?

In the previous post, I proposed some design principles for the construction of a better refrigerator, and suggested that an “open source design” model could be used to improve it continually through collaborative effort, and an iterative process. Being that

Free Fridge -or- The Collaborative Cooler

“Think free as in free speech, not free beer.”   -Richard Stallman Refrigerators are not software, but they could be designed and shared freely like software.  Granted, I’m talking about hardware: steel, glass, copper, insulation, etc., but why not have an

Disposable Refrigerator and Something Better

The modern domestic refrigerator doesn’t use much more electricity than refrigerators from the 1940s.  Admittedly, modern models have greater volume, and no need to manually defrost, but it remains to be seen just how long they will remain functional.  What

Disposable Refrigerators

I hardly know where to start, but that is why I am writing about this – to get my thoughts somewhat in line. What happened to technology?  I know that is a broad question, probably too broad so I’ll narrow

Change of Course – 3 ? 4 ?

This is at least the third or forth time I have decided to change the course of this blog, and my focused area of research.  You could say I wander wherever my attention is captured.  I remain interested in all

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

Ejector Assembly Construction

This is a three part series on refrigeration ejectors.  Part I on theory, is Ejectors in Refrigeration – an Expressor, and Part II on manufacturing techniques, Handmade Copper Ejector. There is a lot of video media, so I will jump

Handmade Copper Ejectors

This is part two of a three part series to get my blog up to date on my ejector research.  Part I was about ejector theory:  Ejectors in Refrigeration – an Expressor.  Part III is about assembling and testing:  Ejector

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

Amateurish Refrigeration Research

I have a High School Diploma, and that is about the extent of my formal education.  My real education comes from years of mechanic jobs, fiddling with and fixing things around the house, building things I need rather than buying

Refrigeration Test Bench – Part III

In Part I, I shared a lot of media relating to my efforts in building a refrigeration test bench.  I intended to build the whole thing from a DIY approach, and utilize a York 210 – Belt Driven Air Conditioning

Refrigeration Test Bench – Part II

In Part I, I summarized my efforts to build myself a testing platform for refrigeration projects.  I cut that post short at about the point where I began doing some heavy brazing work.  Also, the amount of media in that

Refrigeration Test Bench – Part I

This post is going to be a bit long because it will be largely media, since I’ve done no writing for the last several months and have been busy in my shop.  I will let the pictures and videos do

Refrigeration – Back at it!

  Oh my; where to start?  I’ve been away from the blog so long, and have so much to discuss, I fear I know not where to start.  I’ve written quite a bit about refrigeration in the past, but that

The Super-Insulated Tiny House

Housing ideas come to me so fast and change with such regularity, while my writing and drawing lags behind hundreds of iterations.  No bother; I will offer my latest version of a tiny house for your consideration, and for the

Determination and Resolve

I feel a little lost lately.  I’m still looking for a cause to devote myself to.  It’s not like there aren’t enough options; the list of interests I have is endless, but I have little structure in my life to

Build A Community, As If Your Life Depended On It

These are uncertain times to be sure.  The human population is almost 7.3 Billion, and as of this writing, the net population growth on Earth this year is about 602,000; yet it is only January 3rd.  I don’t look at
