Some exciting news out of GE this week. The company demonstrated an OLED "printing" process.

This could mean cheap, energy efficient displays and lighting. From Edison's Desk - The GE Global Research Blog explains:

Since the early days of OLED research, people have said that OLEDs could potentially be made at very low cost because they don’t require expensive semiconductor manufacturing techniques. The ultimate low cost fabrication method would be a continuous “roll-to-roll” process like what is done in newspaper printing. However, so far, no one has demonstrated that OLEDs can be made this way. So about 4 years ago, we set out to find out for ourselves whether it could be done. We found a partner company (Energy Conversion Devices or ECD) with great experience at making roll-to-roll equipment and together we were successful in winning a proposal that we submitted to a government agency (NIST) looking to help fund high risk technology development.

That's not the only green item of note. They're also a post from earlier in the month on sodium-metal-halide batteries that may lead to hybrid systems for heavy industries.
