TED Talks – The best talks on the internet

Posted by Ed on December 1, 2009

TED stands for Technology, Entertainment, Design. The website offers very interesting talks. The vast amount of topics alone ranging from psychology, biology, technology, music, etc. makes this website noteworthy.

From their “About TED” website:
“TED is a small nonprofit devoted to Ideas Worth Spreading. It started out (in 1984) as a conference bringing together people from three worlds: Technology, Entertainment, Design. Since then its scope has become ever broader. Along with the annual TED Conference in Long Beach, California, and the TEDGlobal conference in Oxford UK, TED includes the award-winning TEDTalks video site, the Open Translation Program, the new TEDx community program, this year’s TEDIndia Conference and the annual TED Prize.”

Here are some of my favorite talks:
1) William Kamkwamba: How I harnessed the wind
An inspiring story on how a physics book and a windmill can change your life.
2) Michael Pritchard’s water filter turns filthy water drinkable
This is about a water filter with nanopores. Very dirty water becomes clean and drinkable.
3) Marc Koska: 1.3m reasons to re-invent the syringe
In poor countries syringes are just reused resulting in infections. See how a simple invention prevents the reuse.
4) Johnny Lee demos Wii Remote hacks
Use a Wii controller to build your own head-tracking system and electronic white-board.
5) Paul Debevec animates a photo-real digital face
Facial animation at its finest.
6) Eric Giler demos wireless electricity
Nicola Tesla’s idea of wirless electricity coming true.

Besides, there is another water filter called “lifestraw”. Watch how lifestraw is put to an absolute test and the reasons and science behind it.
