We have written about various uses for coffee and coffee grounds before – for instance, it is a
deodorizer used in clothing, most recently in men’s dress socks. Coffee-bean
chaff (a by-product of roasting) was used to power a modified Ford pickup that
hit a top speed of 65 mph in testing trials in the UK earlier this year. Some
people even use coffee grounds to “de-flea” their pets.
But the coolest innovation we just discovered is the RITI Printer, which uses damp grounds as printer ink! The used grounds go in the ink case, followed by a piece of paper inserted into the small-sized printer. Move the case back and forth while printing and voila, a document gets printed! We have to wonder, though, does it smell like coffee?
