Now, I want to share another video with you, about a woman named Jill Bolte Taylor, a neuroanatomist, who calls herself the “Singin’ Scientist”, and who talks about the experiences she had when she suffered a massive brain stroke. This stroke was caused by an exploding blood vessel in the left side of her brain, and it took her 8 years to recover from it.

“How many brain scientists have been able to study the brain from the inside out? I’ve gotten as much out of this experience of losing my left mind as I have in my entire academic career.” — Jill Bolte Taylor

Here is the video:

These sentences are taken out of the introduction from the website of the talk “Energy Literacy and climate change” by Saul Griffith, which took place at this year’s ETech in early March. Griffith, inventor, genius and general mastermind, continues, where Al Gore’s “An Inconvenient Truth” stops: on each of us personally. And it is not less inconvenient to know how big the energy consumption of our first-world-lives actually is.

What follows is a small example from his talk, where he explains the energy and power basics to all the Mac addicts out there:

Energy is measured in Joules (J)
Power is measued in Watts (W)
1 Watt = 1 Joule / second

Lifting an apple from the ground to a table: ~ 1 Joule

Lifting 40 apples from the ground to a table: ~ 40 Watt

Running your Apple laptop takes 40 Watt.

But I don’t like to condense this great work to just this one example. If you have a little spare time, take a look at Griffith’s work yourself – it will surely be an eye-opener for you if you have not understood or simply not cared about such things yet.
