To add to the mix I found this file while looking up the validity of one barrel of oil equaling over ten years of a person's physical labor, which appears to be a valid claim and for me is the largest reason we have sped up over the past 100 years. My question now is whether we can keep the speed by transitioning to smart technology or whether we should begin learning how to "age gracefully"....personally I am all for slowing everything down regardless of whether we can keep the speed....but maybe that is me getting older :)<div>

In my field, solar, the sales pitch is supposed to include the ROI analysis. I think that defeats the purpose. @252 calories,g per BTU, the human body may metabolize 100,000 BTU(2520 KG calories)/ day for as little as $2 worth of food but if we ran on natural gas, we could sustain our bodies for only $1.20/day! But how would that effect our return on investment and what about the down payment!!! Calculation corrections are extremely welcome.<br>

<font size="+1"> If the nuts & sucrose & other hydrocarbons
in the candybar are oxidized (burnt), they release this much
energy. It's how much energy is available from the candy bar
using chemical reactions. It's what our bodies use as an energy
source.<br>
Shows how efficient animal metabolism is. We all know
intuitively that burning a candybar in any man-made vehicle (even
one of 120 pounds) would nowhere near move that machine the 7
miles or so the woman would travel in the hour. <br>
I remember in high school (too many years ago to count) the
class being led through calculating how many pullups the energy in
a sugar cube would supply energy for. I don't remember the
number, but it was quite a few. There's a lot of room to make our
machines a lot more efficient than they currently are.<br>

I'd like to know a little more about how these numbers are
calculated. Presumably in the case of TNT it is energy released;
in the case of the woman it is expended, but in the case of the
candy bar I'm not sure - contained in the nuts and sucrose? Seems
kind of gimmicky.<br>

Here is an interesting breakdown of different energy amounts:<br>

For example the energy content of a candy bar vs. a pound of
