Self-Deployed Space or Planetary Habitats and Extremely Large Structures
NIAC phase 1 results. NRO research related as well for deployable space telescopes. Rigidized UV cured polymer thin film bubbles for space applications. Possible flat primary mirrors/solar sails, but if they are making spheres, making curved mirror segments should be doable. If you use 6 stabilizing hoops as cut lines, can get 6 sphere segments without much waste (waste could be repurposed as additional mirror segments)

Printing creates 3D replicas of Van Gogh masterpieces - Crave
A Fujifilm process to create Relievos. Basically high end 3D scanning/relief mapping of high end art, down to the brushstrokes, coupled with high quality UV inkjet printers (2D though?). They don't out and out claim 3D printing for replication. Also, these are very high end replicas, though not quite counterfeits.

Seven Next-Generation Energy Technologies Showcased by ARPA-E | MIT Technology Review
Assorted ARPA-E projects. Georgia Tech's thermal updraft turbine, ostensibly to take advantage of dust devil conditions, is probably more suited as a wind turbine for solar updraft towers. The UV/IR specific transparent solar cell tech for windows is interesting too.

'Diamond LED' Can Be Used at 400 Deg C -- Tech-On!
The efficiency wouldn't be great, but I wonder if you could use this as a form of energy conversion to drive a reaction? Specifically, use solar power in the visible spectrum to power the UV LED to drive a UV photoelectrochemical catalyst cell to crack CO2 into CO and oxygen?
