The weather machine

Posted by J. Storrs Hall on December 23rd, 2008

The following is an edited and revised version of the talk I gave at the Global Catastrophic Risks conference that was held in conjunction with Convergence 08 (and which I reprised for Convergence). I’m posting it here because it seems to me that this is exactly the kind of thing Foresight was founded for: to [...]

Nanotechnology provides key capability for artificial photosynthesis

Posted by Jim Lewis on July 16th, 2008

Chinese scientists have developed a nanotech solution to harvest energy from multiple electrons—something alternative approaches to artificial photosynthesis have not yet managed to do.

Reynolds promotes nanotechnology for Earth Day

Posted by Christine Peterson on April 22nd, 2008

Foresight advisor Glenn Reynolds opines about nanotech in the NY Post for Earth Day: MIT’s Vladimir Bulovic calls nanotech a potentially “disruptive technology” in the solar-energy field, offering a complete shift from today’s fossil-fuel environment… Nanotech offers dramatic improvements on the side of energy consumption, too: As computing and other devices become smaller, they become [...]

Nanotechnology to produce electricity from nuclear waste?

Posted by Jim Lewis on April 1st, 2008

Phil McKenna at NewScientist.com news service describes a nanotechnology advance that turns radiation directly into electricity, leading us to wonder if it thus simultaneously provides a use for nuclear waste. This nanotech application appears to be in the early stages of development, so aside from questions of just how efficient and how expensive it would [...]

Ocean iron fuss is not about nanotechnology

Posted by Christine Peterson on March 6th, 2008

We’ve written here before about the plan to put iron nanoparticles in the ocean as a way to increase growth of plankton, thereby absorbing carbon dioxide. Previously this was to be done by a company called Planktos; now a new company called Climos is making similar plans. There was controversy about Planktos, and no doubt [...]
