How One German Village Became a Renewable Energy Leader



Power Play — German Energy Revolution Video (via Clean Technica)

  The German village Schönau forced the grid operator to sell its local grid to them decades ago. Now, that village has become a renewable energy leader. As you can see in the video below, it’s a major producer of renewable energy. One of the pioneers there also has a wicked little electric vehicle…

Esther Dyson on Charter Cities

Charlotte van den Hout –

The Long Now Foundation:

In a recent article on Slate, Long Now Board member Esther Dyson takes up the concept of Charter Cities – Paul Romer’s model for the creation of prospering, sustainable zones of urban life, about which he spoke at a 02009 SALT lecture. Dyson suggests that Romer’s business-model approach to the construction and functioning of urban centers could work not only for new cities, but for old ones as well.

Cities already behave a bit like corporations, she writes. With greater flexibility and open borders, cities can compete for “customers” in a way that countries cannot, and are more directly involved in the daily lives of citizens. Dyson argues that a little more market-style competition can compel existing metropolises to improve their infrastructure and resources as a way to attract potential citizens. This investment will pay off in the form of flourishing residents, who in turn will bring in additional resources and allow the city to prosper. On a larger scale, a prospering city will then compel its neighboring towns to improve their own functioning as well, to become better competitors on the market of citizens and resources.

In the end, it’s all about the long view: it’s about encouraging civilization to prosper as a whole. Cities are an appropriate unit of civilization to work with, Dyson writes, because they have shown more long-term stability than countries or empires:

“Most cities have grown, through evolution, from unpremeditated beginnings. Moreover, they rarely die. Cities (and their imperfections) persist in a way that large political entities, even those of which they are a part, do not. Compare, say, Athens, Jerusalem, Vienna, Beijing, Moscow, or Istanbul, to the Roman Empire, Austria-Hungary, the Ottoman Empire, Imperial Russia, the Third Reich, or the Soviet Union. And, as we are seeing worldwide nowadays, national governments are difficult to overturn and also difficult to (re)build. Democracy does not always lead to liberty or good outcomes. So, perhaps cities are the right place and have the right scale for massive social change.”

Wastewater treatment…evolved

Living Machines –

The idea of using wetland ecologies to clean polluted water was first conceived by Dr. Käthe Seidel, a biologist at the Max Plank Institute, in the early 1950s. Though she was often opposed by colleagues (who sometimes disparaged her as “Bulrush Kate”), Dr. Seidel conducted experiments throughout the 1950s and 60s which showed that plants and microorganisms could clean water much more effectively than had previously been thought.

The idea was taken up by many ecological designers in the 1970s and 80s. One of these was Dr. John Todd, who designed what he called living machines which sought to marry technology with natural processes to create an environmentally responsible way to treat wastewater on site.

The vegetation in Todd’s systems required greenhouses, and were planted on top of “activated sludge” containers. To produce usable water, they required a settling tank called a Secondary Clarifier, which separates a large amount of messy, smelly sludge from the water. The sludge produced by these systems must be disposed of frequently.

Todd’s versions of the Living Machine® were an innovative effort, but they didn’t get consistent treatment, and could not be made to be simple and cost effective. In 1999, Tom Worrell, an investor and partner of Dr. Todd’s, acquired the Living Machine concept, the company, and all of its intellectual property from Dr. Todd. He then put his engineers to work making the technology practical, reliable, and cost efficient.

One of Worrell’s first ground rules was “No Clarifiers.” He wanted a system that would not depend on activated sludge to do the core of the work. The result was the first Living Machines® that used a wetlands model to treat the water without generating troublesome biowaste that needs disposal.

The Next Generation Living Machines® developed by Worrell Water Technologies use beneficial microorganisms (incorporated via engineered biofilms), wetlands plantings, and sophisticated control systems to reliably and efficiently produce water treated to the highest standards. They are stable, healthy, living ecosystems which require less energy to operate, and less work to maintain, than competing treatment systems. They also have a much smaller footprint, and operate in a way that produces no excess waste to be carried away.

Next Generation Living Machines® can be designed for indoor or outdoor applications across a wide variety of climates. For a description of how they work, see our How it Works page.
