This new printer is going to give caffeine addicts a new quick fix. Struggling through the onset of a caffeine headache? Just eat that document you’ve just printed.

That’s right. This technology uses used coffee grounds as ink. That’s a printer that would be pretty sustainable in our household. Currently we put our coffee grounds in the garden. It’s a labour intensive printing process – but ink is pretty expensive and apparently bad for the environment.

Nathan runs St Eutychus. He loves Jesus. His wife. His daughter. His son. His other daughter. His dog. Coffee. And the Internet. He is the campus pastor at Creek Road South Bank, a graduate of Queensland Theological College (M. Div) and the Queensland University of Technology (B. Journ). He spent a significant portion of his pre-ministry-as-a-full-time-job life working in Public Relations, and now loves promoting Jesus in Brisbane and online. He can't believe how great it is that people pay him to talk and think about Jesus.
