The device from industrial designers Hoyoung Lee et al. is a good sign for the environment.
Until recently painting a road sign was a hazardous business. The workmen risked giving themselves a terrible posture, what with leaning down to spell words out onto the tarmac surface. Rarely had bending at the knees possessed such immense value.
At worst the work left them in a permanently bent position, unfit to do anything but paint roads!
But thanks to the invention of the solar-powered road printer, now workmen can put those fears behind them. Unveiled on December 18th at EcoFriend.org, the handy (since it doesn’t need hands) device is the work of industrial designers Hoyoung Lee, Doyoung Kim, and Hongju Kim.
The road printer harbors an onboard solar panel with which it powers itself, trundling along as it jet sprays the tarmac. Road signs are pre-programmed into the printer’s memory – right now it can print such classics as the U-Turn and Stop Sign.
The road printer doesn’t even require workmen to bend down to set it going: the buttons have been designed to withstand the steel-capped toe of a boot. Workmen need only replenish the paint reservoir, from which the paint cartridge
Of course, the device needs charging – but even then workmen need only leave it sunbathing by the roadside.
The EcoFriend.org article doesn’t state if the road printer is intended for commercial use, or is just conceptual. Yet the device may yet become the No. 1 Christmas gift for workmen looking to be spared a visit to the chiropractor’s office.
