New Eco-Friendly
Printer Needs No Ink, No Electricity � Just Used Coffee Grinds
Coffee-drinking computer users
may soon have a new use for their old coffee grinds if a new
eco-friendly printer hits the market.
Featured in the
Greener Gadgets Design Competition, the RITI printer apparently uses
coffee or tea dregs to create computer printouts.
To use the
printer just insert a piece of paper, place used coffee or tea grinds
into the ink case on the top of the printer, then move the ink case left
and right to print the image — no electricity needed, Greener Gadgets
reported.
Because it works
manually the RITI printer is not ideal for large projects and can only
print in black and white, but it will save on the cost of buying ink and
electricity.
The RITI printer is an
eco-friendly printer based on the concept of a new ink system. We
focused on the ink cartridge since it is one of the problems when using
a printer: it's often difficult to replace, costly to refill, and can
stain your hands if mishandled.
The RITI printer uses coffee or tea dregs. The user places the coffee or
tea dregs into the ink case located on the top of the printer, then
insert a piece of paper in the middle. Moving the ink case left and
right will print your image, and as you draw on the paper, dregs
inscript on the paper just like ink.
Using coffee or tea dregs as ink saves the cost buying ink, the burden
of wasted things, and users' work. Furthermore, since the user moves the
ink case in order to make a print, the device doesn't need electricity.
Of course, you can smell a whisper of coffee or tea incense from the
paper printed by RITI.
