Opting In for a Positive Future — Allison Duettmann

Excellent speech.


Our civilization is made up of countless individuals and pieces of material technology, which come together to form institutions and interdependent systems of logistics, development and production. These institutions and systems then store the knowledge required for their own renewal and growth.

We pin the hopes of our common human project on this renewal and growth of the whole civilization. Whether this project is going well is a challenging but vital question to answer.

History shows us we are not safe from institutional collapse. Advances in technology mitigate some aspects, but produce their own risks. Agile institutions that make use of both social and technical knowledge not only mitigate such risks, but promise unprecedented human flourishing.

Watch this video where we investigate this landscape, evaluate our odds, and try to plot a better course.

Water recycling, reuse could dramatically slash cities’ need for fresh water resources, research shows

Using Houston as a model, researchers at Rice’s Brown School of Engineering have developed a plan that could reduce the need for surface water (from rivers, reservoirs or wells) by 28% by recycling wastewater to make it drinkable once again.

While the cost of energy needed for future advanced purification systems would be significant, they say the savings realized by supplementing fresh water shipped from a distance with the “direct potable reuse” of municipal wastewater would more than make up for the expense.

And the water would be better to boot.
