yah just try to feed used paper into your printer. not practical!
This is good technology. Once you have bought paper and taken it to work or home and printed on it, it is a very resource intensive effort to re-collect it, take it back to a paper manufacturer in order to recycle it. I don’t think the process is cost effective, its just one of those things that makes us feel good. Having a small machine that recycles the paper right at the distributed source would save a lot of energy.
I agree
Somehow I’m wondering if vaporizing polymers is ‘greener’ than just throwing the stuff in the trash?
What about coffee stains. Will it undo coffee stains?
Hi-tech palimpsest ping
“What about coffee stains. Will it undo coffee stains?”
And if so, will the same process take them out of clothing?
Obama and his forgers might be very interested in this process!
Wait til the birthers find out about this!
In old times parchments (stretched sheep, calf, or goat skins) were regularly recycled by scraping off the ink of earlier writings for reuse. Same basic concept and, except that the vaporized ink is probably not the best stuff to breathe in, pretty cool.
Oh goody. Once we find a way to do this with toilet paper, Sheryl Crowe can go back to using more than one square!
The very definition of a "palimpsest" is a page which has been reused. Most calligraphers and illuminators used gum sandarac or some other type of pumice, but Emperor Nero, who was a calligrapher in his own right, was reported to use the chopped out tongues of slaves.
I had to present a certified, raised seal and signed BC to the Texas Public Safety Officers to get a drivers lic. last week! Went home pulled it out of a briefcase and was back with in an hour. Seems Berry can’t or wont do that!
Why stop at clothes. What about tattoos?
It’s a good thing that lasers do not use energy

What percentage of office paper people throw in a recycling bin are reusable this way? They get stapled, folded, and mutilated. They get damp, wrinkled, stained, written on with pens and markers. They get handled with sweaty oily hands, stuffed in books and briefcases, taped, and then end up wrinkled from being in the bin. I like to fold papers three time and stuff them in a shirt pocket. Would that be a crime?
Everyone would have to treat each piece like a valuable work of art and make sure to stack it neatly when its unprinting time comes.
All of this stuff sounds great “on paper” but its implementation is a different story. You’re still going to have to grind most of it up and make new paper out of ole.
problem is. The fake BC wasn’t printed so there’s nothing to unprint lazerly.
I’d bet zero wished this lazer thing was around 36 moons ago. He could have altered the BC he found in a book... then again toner wasn’t around back then.
