Reversing the Technological Dilemma

December 17, 2009

By George Kimbrell, International Center for Technology Assessment, and the Center for Food Safety

A guest blog in the Alternative Perspectives on Technology Innovation series
Andrew asked us to write about “how technological innovation should contribute to life in the 21st century.”  Technological innovation is often blindly referred to as “progress.”  The question is — progress towards [...]

Confluence: Where communication, coupling and control collide

June 26, 2009

Part 7 of a series on rethinking science and technology for the 21st century
Yesterday, I listened to respected economists discussing geoengineering; gave a Skype interview on nanotechnology from the comfort of my own home; and watched as reactions to Michael Jackson’s death spread through virtual web-based communities.  Twenty years ago, when Jackson was at the [...]

Geoengineering: Are we grown up enough to handle it?

June 14, 2009

If there’s one thing that’s guaranteed to unite global warming “denialists” on both sides of the aisle, it’s geoengineering – the intentional planet-wide manipulation of the environment.  At least, you might be left with that impression after reading the comments following a thoughtful piece in Monday’s Wall Street Journal by Jamais Cascio.

Cascio describes himself as [...]

Steve Chu’s White Revolution

May 27, 2009

It feels good to be ahead of the curve sometimes. About this time last year, I was slaving away painting my roof white – much to the bemusement of my Northern Virginia neighbors and friends. So I couldn’t help feeling just a little smug this morning as I read that US Secretary of [...]

Nanotechnology: From nano-novice to nano-genius in 13 steps

May 26, 2009

Back in April, the folks at the PBS station THIRTEEN asked me to answer 13 questions on nanotechnology and the environment for their website feature Green Thirteen.   The questions ended up covering most of nanotechnology – what it is, what it’s good for, what the downsides might be, and how we might overcome potential problems [...]

Coupling: Actions and consequences in a shrinking world

April 3, 2009

Part 2 of a series on rethinking science and technology for the 21st century
In the previous post in this series I introduced the idea of the three “C’s:” Coupling Communication and Control—three factors that together challenge conventional ideas on how science and technology are best developed and used within society.  Following on from that introduction, [...]

Building better batteries, the Chinese way

April 2, 2009

Reading yesterday’s New York Times, it seems China could well be poised to leapfrog the West in advanced battery technology (China Vies to Be World’s Leader in Electric Cars). According to the article, Chinese leaders have adopted a plan aimed at turning the country into one of the leading producers of hybrid and all-electric vehicles [...]

Geoengineering: Does it need a dose of geoethics?

January 28, 2009

It’s been a big week for geoengineering.  First there was the news that the world’s largest geoengineering experiment to date is about to start in the Southern Ocean.  Following close behind was a new study on how geoengineering projects could potentially impact global climate change, ranging from covering vast tracts of desert with a reflective [...]

Nano-silver: Old problems or new challenges?

September 9, 2008

The blogging community is no stranger to the use (and possible abuse) of nanometre-scale silver—products ranging from silver-enhanced socks and toothpaste to plush toys and cure-alls have all appeared in the spotlight recently. With each passing month, the number of nano-silver gizmos on the market is growing.

Smart materials; smart choices?

May 31, 2008

Why nano?  Why care?  For non-nanotech initiates, an obsession with nanotechnology must sometimes seem a bizarre occupation of the sad and lonely.  And even within the nanotechnology community, who hasn’t had occasional doubts over the legitimacy of singling out “nano” as something special?  Yet occasionally a piece of work comes along that helps put things [...]
