Greenhouse - External vs Internal on Earthships

I read the article about the passive greenhouse experiment and the conference that Paul did about it. I'm planning to buy the movie

But I was wondering if this experiment of using both a greenhouse AND tubes for heat extraction would be something good to add to our house ? Like on Earthships ? By the way if I'm not mistaken they have such kind of tubing for passive heating or cooling right ?
So this experiment would be a way to do the same as Earthships but in an EXTERNAL way ? Or do you see lots of differences ?
Thanks a lot, I would love to understand.

I am intrigue about you idea for a greenhouse with earth tubes.  I feel that will work.

You are not the first to ask about this.

So to me an external greenhouse with earth tubes would be lovely:

Hey Anne,
thanks but I did not invent this sadly It is an experiment Paul did with other explorers !

And this heated tube into a trench seems to work really well....

I was just wondering if this tube-heat-exchange could work for a house heating, and if it is not the same approach as earthships in fact... ?

Yes, it works for cooling and heating homes.

I gave you an example of how they can be added to existing homes.

This technology is also used in earthships and passive solar homes.

thanks, but after reading I did not find a clear process on how to do it and how it works for a home.
But no worries, let's forget it. I'll follow what Paul shares and try to get a clear explanation on how to do it, on video or ebook. Rather than trying to grab pieces of infos here and there.

I'll use the earthship approach in the meantime.  Thanks

Cheers
