All the roads that’s fit to print

Paul Raven @ 15-11-2010

Gasp in awe at the crazy range of stuff we can ‘print’ nowadays… and then try not to think too hard about the economic job-destruction implications as you watch video footage (which, given it was linked to by BLDGBLOG, I’m assuming isn’t some sort of clever spoof) of a machine that can ‘print’ a paved Tiger Stone road as easily as laying a long roll of linoleum:

Geoff Manaugh’s post linked above already mentions China Mieville’s Iron Council as a fictional almost-precedent, but it’s such a powerful conceptual image that I think you could get more stories out of it without treading on anyone’s toes…

Stuff-we-can-(theoretically)-print bonus content: we’ve mentioned transplant organ printing before, but here’s an explanatory video from the Biophysics Lab of the University of Missouri-Columbia [via Fabbaloo]:

Solar cells printed on paper

Paul Raven @ 06-05-2010

Chalk up another point for MIT, bounteous font of great boffinry – their latest offering to the world is a solar cell you can print out onto paper. However, I wouldn’t get too excited about it:

… the new solar cells are created by coating paper with organic semiconductor material using a process similar to an inkjet printer.

The MIT researchers used carbon-based dyes to “print” the cells, which are about 1.5 to 2 percent efficient at converting sunlight to electricity. That falls well short of the more than 40 percent efficiency record for a multi-junction solar cell, or even the recent 19 percent efficiency record for silicon ink-based solar cells. But Vladimir Bulovic, director of the Eni-MIT Solar Frontiers Research Center, told CNET any material could be used to print onto the paper solar cells if it was deposited at room temperature.

It will still be some time before solar cells can be installed with a staple gun, however, as the paper variety are still in the research phase and are years from being commercialized.

Drill, baby, drill?
