More TED Talks

As Puggling has posted before, TED puts on various presentations by famous (and not so famous) folk about very interesting topics, usually aimed at improving the world we live in.  Here is one such talk by a former Microsoft guy who has a HUGE variety of interests.  Topics range from penguin poo, to nuclear reactors to T. Rex bones.  Enjoy!

For a more serious topic on what needs to be done.  Bill Gates (you may have heard of him) gives a presentation on energy usage.
