Electrochromic Visor Aids Motorcyclists
opticsorg writes "A team from Uppsala University and the firm Chromogenics Sweden AB have developed a flexible electrochromic foil and integrated it into the visor of a motorcycle helmet. The result is a visor that the rider can electronically switch between dark and transparent states. Applying a voltage of about 1V to the initially transparent visor causes it to darken in a matter of seconds. When the voltage is turned off, the visor keeps its properties, while applying a reverse voltage makes it revert to its natural lightly tinted state."
Any real rider doesn't feel the need to wave his cock around, and knows there's nothing magical about picking up an old bike on ebay and spending a month of weekends in maintenance classes. Or, I'll bet you take yours to the shop whenever you smell oil or stall you poser.
