Painting with Toxic Runoff

Allison Guy
September 4th 2013

Throughout the US, coal mines abandoned before environmental laws produce acid mine drainage, a soup of toxins that can turn contaminated streams as acidic as lemon juice. One of the main byproducts of acid mine drainage, ferric oxyhydroxides, also happen to be the base for commercial red and yellow paints. Guy Riefler, a professor of environmental engineering at Ohio University, has invented a method for collecting the iron sludge in the runoff and converting it into pigments. With the help of artist John Sabraw, Riefler is tweaking his process with an eye to eventually manufacturing commercially viable paints. There's certainly no shortage of raw materials: a single seep near Ohio University oozes out enough sludge to produce one ton of pigments every day.

Should men be able to give birth to children?

Koert van Mensvoort: Is the artificial womb frankenstein-like symbol of (male) engineers trying to steal the magical womb from women? Or… is it a feminist project and needed to reach through equality between the sexes? I personally lean towards the latter. To me it feels like progress if a girl can tell a guy to carry the womb for a change.
