IceWriter  (idea #111)
Date: 2004-02-19 
Category: Technology / Heavy Equipment
Price: 100
Target Audience: Zamboni

Description: New from the Zamboni Company, IceWriter is an ice-resurfacing vehicle that "prints" semi-permanent color images of any size as it traverses the ice. The robotic vehicle sweeps over the image area line-by-line, while a hot metal print-head underneath melts holes in the ice, one for each pixel. The vehicle then sucks up the water, mixes it with vivid, biodegradable dyes, and re-deposits it into the hole, where it soon re-freezes. The resulting long-lasting color pictures turn rinks or frozen lakes into colorful billboards visible from far away-- even from airplanes!
