I spent the last 5 years running a series of biochar start-ups in Colorado, and recently sold Biochar Engineering Corporation to a private company that wants to scale-up the technology. Biochar is a charcoal-based soil amendment that has the potential to remove net carbon from the atmosphere, while improving soil fertility, and in the near term cleaning up and restoring degraded mine-sites.

We spun-off the existing field-scale technology to a new company, Biochar Solutions focused on using forestry waste for mine-land restoration.

For the past twelve years I have been focused on catalyzing a network using digital technology to address global ecology, democracy and the other pressing systemic issues. Planetwork has once again become my main focus as social media has come of age and yet still falls far short of what we envisioned over a decade ago.

Pythagorean Vitruvian Man

In this elaboration of the Vitruvian Man, an equilateral triangle, representing the symmetry system 3, and a pentagram, representing the system 5, are added to the square, representing the system 4, to complete all three Pythagorean families of symmetry, all in the golden mean relationship to the radius of the circle. The key to the puzzle is that the golden mean of half of the edge length they all share, sets the height to that edge at the arms.
