Visualizing energy data

 Chart from USA energy data ( http://energyliteracy.com ):

onsite interactive map shows energy wasted in different sectors
"By clicking through the chart, you can see exactly how much energy is used for every activity. (...) Almost 1% is used just to pump natural gas around pipelines; 2% goes to making cardboard and other paper products. Around 16% is used to grow, distribute, and cook food. Looking at the total picture helps make the point that some of the ways that we think about energy aren't quite right. Refining petroleum uses about 6% of total energy in the country, but isn't considered when we think about fuel economy in cars. (...) Mining oil and gas uses even more energy." (in link)

memex

Vannevar Bush (1945). As We May Think. The Atlantic Monthly, vol. 176(1), pp. 101-108.

Drawing of Bush's theoretical memex machine was published in Life Magazine, November 19, 1945, vol. 19(11), p. 123, also under the title «As we may think». Since I have not found an image of the original article, I'll use the one circulating in many different places that have paid homage to Bush vision.

PS - From Memex To Hypertext arrived (same picture in p. 109)
