“Scientists at MIT have discovered molecules that spontaneously assemble themselves into a pattern that can turn light into electricity — essentially a self-creating solar panel. In a petri dish.” [Link]
I was wondering if this discovery has a practical application. A commenter has the same question, someone else answers:
The implication of the addition of an ‘additive’ to disassemble into a liquid ‘soup’ is that the stuff can be sprayed/painted onto a surface. It also means that it can be mixed with polymers and woven into materials etc.
Paint or spray your house/car/boat/aircraft with it, and decide you want a different colour? No problem, spray the additive/solvent and it comes off.
(Thanks to Audrey Thompson for the pointer.)
This is odd – e-democracy.org’s 125-member United States issues forum, is described as “a civil, more deliberative discussion of national public policy issues and politics in the United States among people with diverse political perspectives.” I joined, and was having an interesting and potentially productive discussion with an intelligent, seemingly reasonable Tea Party conservative. However my last post in that discussion was blocked – the list limits members to one post per twelve hours. “We limit the number of posts any one person can send within a set time frame to increase the number of voices heard and keep overall e-mail volume in check. Please try posting again later.” The implication is interesting: democracy is not about enabling discussions, but restricting them. From their perspective, I suppose the idea is that an unrestricted list will be dominated by a few voices. Savvy online communitarians know that every forum will have a few vocal members, though, and many more observers who rarely if ever speak.
A restriction like this just seems tone deaf to me, especially on a list that espouses deliberative discussion. The restriction leaves the list inherently stilted.
