Intro: The Green Pail Retained Heat Cooker
The Green Pail retained heat cooker holds many foods at cooking temps long enough that simmering is not necessary it will hold 7 liters of pintos hot long enough to cook them well done and keep them above 170 deg F for 5 hours.
The Green pail is basically an inner shell isolated from an outer shell with loose fill insulation.
The Green Pail retained heat cooker is green because:
1- It is made from recycled plastic pails
2- It saves the energy that it takes to simmer food.
3- It keeps the heat out of the kitchen saving summer time ac cost
4- It can be made locally from local materials with local labor.
5- It saves the time necessary to watch food simmer, you can simply set it and forget it, walk away and leave it for hours.
6- It can hold food at safe temps between meals making refrigeration unnecessary, which could be handy in off grid situations.
7- It is a street vender micro enterprise design that someone could build and sell at flea markets, garage sales.
Step 1: 7 Liters of Pintos of Cooked Well Done.

Step 3: The Green Pail Parts
The Green Pail is made from 2- 9" cake pans, that cost $1.50 each at the dollar store, 30" of 14" wide aluminum, that cost $2 at Home Depot, 2 lids, a 5-gallon plastic pail and some screws and sawdust.
Step 4: The Inner Shell Is Cut
The aluminum is cut for the inner shell, with enough length for lap.
Step 5: The Inner Shell Is Sized
The aluminum is fitted tight to the cake pans, which act as heads for the inner shell.
Step 6: Now to Make the Cap
The insulated cap is made of two parts, a lid and a cake pan/head filled with insulation.
Part of the flange is removed from the lid.
Step 7: Two Lock Tabs Are Left So That It Is Easy to Install and Remove.
Two lock tabs are left so that it is easy to install and remove.
Step 8: The Rolled Flange Is Cut in 4 Places
The rolled flange is cut in 4 places
Step 9: And Flattened So There Is Enough Room to Install the Screws
and flattened so there is enough room to install the screws
Step 10: The Pan/head Is Filled With Insulation
The pan/head is filled with insulation
Step 11: And Screwed to the Lid
And screwed to the lid
Step 12: Size the Inner Shell for Its Length
To size the inner shell for its length, it is installed in the pail
Step 13: And the Lid Is Installed and Measured
And the lid is installed
The amount of the inner shell to be trimmed is measured
Step 14: The Inner Shell Is Marked
The inner shell is marked
Step 15: The Inner Shell Is Trimmed
The inner shell is trimmed
Step 16: The Head on the Cap Should Fit Tight in the Inner Shell
The head on the cap should fit tight in the inner shell
Step 17: The Ring Is Made
A ring is made from one of the lids to blank off the inner shell and outer shell to retain the loose fill insulation. The outer flange of the ring is trimmed away.
Step 18: A Line Is Scribed for the Inner Hole
A line is scribed for the inner hole
Step 19: The Inner Hole Is Cut
The inner hole is cut
Step 20: The Ring Should Fit Snug Over the Inner Shell
The ring should fit snug over the inner shell
Step 21: Add Enough Sawdust to Fill the Bottom Head
Add enough sawdust to fill the bottom head
Step 22: Sawdust Is Filled Around the Shell
Sawdust is filled around the shell
Step 23: The Ring Is Installed
The ring is installed
Step 24: The Ring Is Screwed From the Outside
The ring is screwed from the outside
Step 25: The Fit Is Tested
The head should fit snug in the inner shell
Step 26: One Way to Use the Green Pail
You can use the cap as a base and the pail as a cap
Step 27: Another Way to Use
You can put a pot in the pail and use the insulated cap
Step 28: Scrape Off Painted Label
I have decided that spray painting is not a very green thing to do so I have started scraping off the painted label.
Step 29: A White Green Pail
So if your Green Pail is white that is even greener, so to speak.
