First try refreshing your browser or try another browser. If that doesn't work, read the following.
All the videos on my website are embedded from Youtube. From what little information I can find Youtube is testing turning off videos for certain users that are not logged into a Youtube account or using a VPN to view videos. If you have a Youtube account, please try logging in and see if you can then view the videos on https://mvotd.com. If you're using a VPN, try turning it off to view the videos. There are a few other work arounds but they are pretty confusing to use. If you have the skills you might try searching Google for "Youtube Sign in to confirm you're not a bot" for a fix. I didn't see any that looked easy. Our best hope is that Youtube completes their test and realizes this is a big mistake. Until then, please check in daily to see if you still getting the error message. Sorry it took so long to figure out what was going on with this. Mel
Description
Rammed earth is an ancient building technique that has been modernized to be stronger, more durable, and energy efficient with the addition of structural components like rebar as well as insulation. SIREWALL is the acronym for this modernized green building technique and it stands for: Structural Insulated Rammed Earth.
In this video, we’re meeting Tony Johnson from Earth House Holdings to learn about rammed earth construction, and to get a peek at the rammed earth home he is building for his family in British Columbia, Canada.
To follow and find out more about Tony’s rammed earth construction:

The rammed earth mixture in this project contains soil aggregates (~90%), cement (~9%), and pigment (less than 1%). It is mixed and deposited into plywood forms, then it is rammed with a pneumatic tamper to squish the earth down, and finally, it is cleaned up with a manual tamper. The wall is built in lifts of 6 inches at a time which gives the wall the striations and lines that are typical of rammed earth.
Some of the benefits of rammed earth as a green building technique include the fact that it is energy efficient due to the thermal mass and thermal break created by the insulation. It is also an airtight material which means that there’s little heat loss from a poor air barrier. Some studies have also shown that it is fire resistant as well.
