Here are some of the benefits of rocket mass heaters:

cheap to run. About a tenth the cost of natural gas, electric or conventional wood heat.
clean. They emit about a hundredth of the smoke of a conventional wood stove.
good for the environment. Less than 2% of CO2 emissions of natural gas or electric heat. Can reduce your carbon footprint as much as parking 7 cars.
sustainable. It uses a renewable fuel which is easy to find and store.
cheap to build. About $200 to $600.
quick to build. Often built in a weekend
luxuriant. Like the luxury of a heated floor but without all that standing.

Watch the intro video:

better wood heat

DVD 1: cob style

This is all about the ol' reliable cob style rocket mass heater. Watch how a couple spent a winter in a tipi with only a rocket mass heater for heat, and how comfortable they were. Even at 26 below! This DVD works as a stand-alone purchase, or can be purchased with the rest of the set.

DVD 2: pebble style

Watch the construction of three pebble style rocket mass heaters. This style of construction is easier to deconstruct and move than the traditional cob style heaters. They are also better for installing on wood floors as they are generally much lighter.

DVD 3: shippable core

This DVD shows an early prototype, and some how-tos for a variety of techniques for building one.

DVD 4: innovators event

This event has been captured on film, featuring the best of the best in the rocket mass heater arena. This video shows a variety of builds such as a rocket mass heater shaped in a circle with glass to show the burn; an outdoor rocket mass heater/cooker/smoker; A "batch box style" rocket mass heater with measured output cleaner than anything we have ever encountered; and an indoor rocket stove, griddle and water heater. Very cool stuff.

This version is provided for people that are tech savvy and have limited internet stuff. If you are not sure about what this is all about, then don't get the download version! You want the HD streaming version HERE.

About two minutes ago, I got word that the narration in the videos is garbled.  Specifically, if you go to the first video (cob style) and listen to the very beginning, at 0:00:08 I say "permies.com".  It sounds fine to me, but it sounds garbled to this other person.

I am using VLC on linux.   The other person is using the media player in windows.

So solve this, we first need to understand if the video has a problem, or if it is a fluke on the other computer.   So we need data.  

Anybody have these videos and windows?  How is the quality of sound at that one point?

From my email:

I just bought the newer main 4 downloads for better wood heat but they won’t download to my iPad or my iPhone. Each time I try it just comes up with a black screen, with the play button crossed out in the center. I assume your download is compatible with Apple products or you would’ve mentioned it so any idea what am I doing wrong? We really want to watch these and hoped to have the version available on our phones for when we are building...? But if it won’t work maybe we could do a direct streaming once instead

I know that the videos can be viewed by apple products because a lot of people have done so without a problem.  

In doing some research on my end, it seems that you have not yet downloaded any of the files.  

My first guess is that your device is full.

I am posting this publicly because I don't have any apple products and I don't know how to even check that there is room on the device.  BUT!   There are a lot of people here that have probably viewed these very videos on an apple device that might be able to help.

I think the next step is for you to share the version info for your devices and how much room is available on each device.

I have plenty of space in my iPad, still 179 GB.  My iPhone Has 48 GB free. They are both updated to newish versions, I can find out numbers if that’s helpful. When I try to download any of the 4 files I just get the black screen with the play button crossed out and no downloading.

We tried downloading to my husbands laptop which uses Microsoft/windows and the first one worked so I guess it’s just an apple issue (or user error on apple?) if someone more techy than us has ideas on how to make it work on apple products please let me know. We’d like to be able to view them out at our property where we plan to build it if possible. Thanks!
