Disposable Lasers Created Using Inkjet Printer (dailymail.co.uk)
An anonymous reader quotes this report from The Daily Mail:
Researchers have invented a way to print lasers that's so cheap, easy and efficient they believe the core of the laser could be disposed of after each use. The disposable organic lasers amplify light with carbon-containing materials and they are produced using a simple inkjet printer...
"The low-cost and easiness of laser chip fabrication are the most significant aspects of our results," said Sebastien Sanaur, an associate professor in the Center of Microelectronics in Provence at the Ecole Nationale Superieure des Mines de Saint-Etienne in France... One obstacle that has held back organic lasers is the fact that they degrade relatively quickly -- but that hurdle might be less daunting if the lasers are so cheap they could be tossed when they fail. Sanaur's research team produced their ultra-low-cost organic laser using a familiar technology: an inkjet printer... They estimate it could be produced for only a few cents. Like the replaceable blades in a razor, the lasing capsule could be easily swapped out when it deteriorates.

Why the fuck would anyone create yet another disposable anything? Is there a widespread contagion of viruses caused by unsanitary lasers shared by groups of people?
We live in a closed system with limited ressources, stop wasting them and turning them into garbage!
... laser printer?
You'd think professional journalists would properly cite even link to the original publication.

Why do you hate capitalism?
Because it is destroying the world and bottom line man kind?
Cost free eBook I read (by iBook/Kobo/Amazon/ObookO/Gutenberg etc.): "The Green Odyssey" by Philip Jose Farmer.
Now nerds want comic book movies and to complain about the doom and gloom of the future. Well good luck with that. The enlightenment is dead, long live romanticism. I hear there's a new zombie move coming out.
Why do you hate capitalism?
because it...
* enables psychopaths to gain power and bleed your for all your worth
* has corrupted our government and degraded our rights
* promotes misinformation
* is destroying our society
* is killing our next generation with sugar
* is killing our ecosystem both on land and water
* is unsustainable
