Eric Giler demos wireless electricity | Video on TED.com
A very cool concept, wireless electricity, that seems to have its roots in Tesla. And again, while it was promo-ed to show how it could make more lives convenient (with a brief mention of recharging implanted medical devices), what kind of impact could this have on impoverished schools?

This amazing demonstration of the way LED light bulbs can utilize current infrastructure to provide secure transfer of digital information stopped me in my tracks. Many of the posts to the video discuss the possibilities for spying and espionage, but I am trying to imagine the implications it could have for schools. A teacher could provide specific information to students within a classroom directly to laptops, students could utilize cell phones or PDAs as 'clickers,' assignments or projects could be delivered to and shared among small groups of students - only within light range - without the fear of cheating.

Better failure
Tim Harford: Trial, error and the God complex | Video on TED.com
Tim Harford voices an excellent argument on creating better failures in order to push innovation. I would argue that schools need to teach students that failure is an essential part of learning. I also really like the division between the God complex and trial and error. It makes you stop and look at your way of thinking ...

It seems there isn't a good place to catalogue the little gems of invention found on the web amongst viral videos, games, and net-mercials. This blog will be one such place to reflect on those goodies I find in my life online.
