"Due to its high degree of microporosity, one gram of activated carbon has a surface area in excess of 3,000 m2 (32,000 sq ft)"

That means 2 grams of activated carbon have the surface area of a football pitch.

Woah.

@fribbledom My favourite Activated Charcoal Factoid is that the highest surface areas can be achieved from coconut charcoal, and that there are "vintages" of high-porosity coconuts, and that this all matters a great deal to fusion researchers who need coconut charcoal for achieving hard vacuums. :)

@fribbledom
Y'know, unless that dootball field has a gram of activated carbon on it's surface
