∞ If a MacBook Air Were as Inefficient as a 1991 Computer, the Battery Would Last 2.5 Seconds

The Atlantic:

Imagine you’ve got a shiny computer that is identical to a Macbook Air, except that it has the energy efficiency of a machine from 20 years ago. That computer would use so much power that you’d get a mere 2.5 seconds of battery life out of the Air’s 50 watt-hour battery instead of the seven hours that the Air actually gets.
