Hi there! Erik here. I am the founder of a non-profit organization founded with the purpose of teaching and researching sustainable living practices.

I am an engineer and an Earth-architect, a graduate and former faculty of Nader Khalili’s CalEarth Institute. I was the first person to fully design and get permitted a Superadobe-Earthship structure in a major US city (Las Vegas) back in 2014. In 2016, we purchased 2.5 acres of land in the California Mojave Desert, and since then we have been working hard to create Gaia Earthen Technologies Polytechnic's first campus.

We love to teach and learn new skills related to sustainable living, and you will have the opportunity to contribute to the creation of a revolutionary, money-free egalitarian-style community. If you're interested in this type of living, come join us and become a part of the community.

We enjoy hosting, getting to know people, making them feel like this place is home. We are passionate about the work we do in sustainable living and sustainable building. We love to explore the wild places around us by hiking, mountain climbing, rock climbing, snowboarding, and swimming. We'd love to show you around the beautiful desert we live in!

My second experience in Tranqvillium was AWESOME and full of challenges, we built a bench using recycled materials and faced the strong winter winds, we talked about various topics and visited very beautiful rural and wild areas, an experience that I would definitely do it again and Erik is a person who is always open to dialogue and available.
I suggest you prepare as best you can, taking into account that it is a place surrounded by nature and contacts with people are rarer but also much more significant. CIAO AMICOOO!

That was my first Worldpackers experience and definitely an unconventional one. The desert is so beautiful and the living conditions are so much better than described in the survivor’s guide. There is a certain degree of freedom in terms of choosing a project you want to work on, but once a project is chosen, the commitment is expected. Erik is a great host, kind and generous, and a very interesting person to have conversations with as well. I was the only worldpacker on the property for about 2 weeks, but never felt unsafe. Overall, it was a memorable experience, and I’m very grateful for it

This was my first worldpackers experience and it was amazing!
Erik is one of the best person I've met in my life, and we get well in any aspect of my living in Tranqvillium. This is not a place for anyone, but I think anyone that is involved in community living and sustainability can learn a lot from this place. Living following the daylight really changed my life, and in Tranqvillium I learned to be conscious about every aspect of living: working, eating, managing resources, managing waste and be part of a community. I hope more people go to Tranqvillium to help him improving the place :)

Desert is not for everybody, however, Eric is very good with ensuring you're fully aware of what you're signing up for. I loved my stay here, and I feel empowered by this experience in my abilities. I learned how to use power tools, build dome buildings, mud walls, etc. On the weekends, we always went for adventures in nature -hot springs, slot canyons, mountains, sand dunes. It was truly amazing! I miss this place already:)
