High-precision Membrane Mirror Research in the SolarVillage Testfield of Tamera

August 2016

We are reaching an important milestone in the Testfield: the high-precision membrane mirror that we have been working on for the last two years, is standing. A team within the technology group has designed and built a prototype solar concentrator by innovating and developing the inflatable membrane mirror technology first introduced by father and son Hans and Jürgen Kleinwächter several decades ago. The present advances are the result of a dedicated team within Tamera working in cooperation with Jürgen Kleinwächter, SunOrbit (Germany) and supporters in India and Australia. more

Biogas Upgrade

Energy Autonomy in Tamera’s Solar Kitchen

The Solar Village Test Field is in the processes of upgrading its biogas system, making further steps towards real energy autonomy, regenerative ecology, and sustainable community. A biogas digester is a liquid composting system, which produces methane gas that we capture as an energy resource. Starting with organic waste from our kitchens and garden, we produce both abundant cooking gas and rich liquid fertilizer. If you haven't visited our autonomous Solar Kitchen, please do so for an in-depth introduction! more

Hope Container

A Planning Time in the Solar Testfield of Tamera

The Hope Container is an idea of the inventor Jürgen Kleinwächter. It is a planned energy-producing center for 50 people, equipped with a kitchen, greenhouse and garden, showers or bathroom and a place to eat and meet. The system will also produce drinking water and includes a cool room for food storage. As the name implies, the Hope Container can be built into one or more shipping containers for ease of transport, to crisis areas for example, or as a core component for regenerative settlements. The Hope Container is intended as a basis for architectural design that supports people to come together in learning and social exchange. more

Self-Realization and Autonomy

12.04.2014, General Study in the Tenthall, Tamera

Jürgen Kleinwächter:

"I will speak today about autonomy. Yet I will begin with an entirely different concept: self-realization. The subject arose this past Thursday, when I had the good fortune to be present for a historic, symbolic walk together, into a new Tamera. After this we came together in the Aula, and Sabine Lichtenfels found very moving words to describe how the Tamera community was growing into togetherness, from the individual groups—the ecologists, the technologists, the artists—into a whole. It was beautiful, and came to a high point with the sentence: Everyone has the right to self-realization!"

Workshop Grand Opening

We did it! We have a new workshop!

We spent two weeks getting the machines, tools and materials from Jürgen Kleinwächter's workshop into the new shelves in our workshop. It fits perfectly! So far, with all of the big machines, workbenches and much of the materials and infrastructure in place, and a good deal of the hand-tools, it is striking how much MORE space we have to work than ever before. It feels like everything has landed where it was meant to be. Outdoors we have a good collection of Jürgen's inventions: two SunPulses, a big fix-focus mirror, second greenhouse structure and much more.

News from the Solar Kitchen: “It's great to be on-sun!”

4th of June 2012

The technology team has moved to the solar kitchen and started a 3 months energy autonomy experiment. We will cook and live in and around the kitchen until August, testing and modifying the equipment there. We intend to fit a new storage tank to Jürgen Kleinwächter's hot oil solar system, so that we can store solar heat to supply the kitchen with electricity and use the cooker whenever it is needed. And we are working with input from Uli Stempel on biogas refrigerators – simple refrigerators removed from caravans, which can be modified to run on biogas. We are also cooking with biogas, improving the Scheffler mirror and are already living in energy-abundance.

SunPulse

May 2012

We are now presenting the SunPulse Water project that we are planning for 2012, "Solar water pump for those who need it most." It's a significant upgrade to the already great beta-test model of Jürgen Kleinwächter's SunPulse that we have running in the testfield, coupled to a very interesting field-tested pump design and incorporating all the improvements we can. Take a look, and join us at Betterplace - SunpulseWater, to add comments and your support. Please help us to manifest this. Make a donation if you can.

Extract from Jürgen Kleinwächter´s inaugural speech

The more you know, the better it is for you, on the one hand – and the more responsibility you have on the other hand. Responsibility to bring autonomy to poorer people. We are living in the age of space travel – and we know how to manage the a satellite which is a closed system. We would not come to the idea that the astronauts in the space station are divided in two thirds poor and one third rich people, and that one group is doing the all the work and the others are not – they must cooperate. And what we do not realize is that we are already living on a big satellite, one that is much nicer than the technical ones, one that is covered with a fantastic biology, with the ecosphere and we are on our way to destroy it ….

New Micro-Biogas Plant

Together with the urban planner and energy activist T. H. Culhane from the US, the participants of the Global Campus built a new, small biogas plant within three days and finished another one that had been started last year. With the organic kitchen waste of just one day, enough gas for two hours of cooking can be produced. This way the solar kitchen can be complemented with a biogas driven stove at night or during rainy days.  more

Extension of Testfield 1 in 2011

Construction Phase of a Workshop for Training, Research and Maintenance

 

New concepts for local and as self-sufficient as possible energy supply are being developed in Tamera's TestField 1 and tested in everyday life. At the core stands Jürgen Kleinwächter's Solar Power Village technology. Energy is generated by a low-temperature Stirling engine – a technology that can be produced even under very simple conditions in subsistence economies. The question of energy storage is also well-solved in the Solar Power Village.

 

These innovative approaches also bring the possibility of independence when used in poor regions of the world. It is intended that representatives of peace-villages and other initiatives will accompany the construction and development of the technology from the very beginning. For this, and for further technological developments, the next construction phase of TestField 1 needs a workshop for training, research and maintenance. 

 

The existing single-storey, 240 m2 workshop will be upgraded to a 768 m2 building including usable loft space and 123 m2 of balcony. The workshop has so far served as a resource for the construction of Tamera's infrastructure. It will now serve a broader function as a research and training workshop for TestField 1 and for the Global Campus. The costs for the construction step of this year including the equipement for research and eduaction will be 480.000 Euro.
