POWER UP - Just how much power was created? Science buff topic

Got some really nice info to share with the rest of you guys, that are into science. If you've never sat down to think, just how much "power" am I using to do this thing I'm doing right now compared to something else in the world? Like, how much raw physical power am I using when I am typing on this keyboard vs to someone pitching a baseball. If you've never thought of it the slightest.. here's a list to get you started on thinking.

What's a joule?
Picture the energy to hold a kiwi in your hand, and move it 1 meter (3 feet) straight up in the air. That's 1 joule.


The following are in millions/ billions of joules for the ones higher up the list. This is a scale of from 0-68, how where they rank in terms of power exertion.

That is really interesting, naisho. Thanks for posting it! I really enjoyed thinking of joules in terms of cosmic phenomena and every day things because in physics class they always taught us the numbers without attaching any concrete meaning. So it's nice to have that now. <smile>
