hello monkeys,
apparently /sci/ wont fuck off from- or is hung on the differences between- science and technology, so please enjoy my ted talk.
let me draw up a picture to show you what i mean, because i am bad at explaining things! but, in essence,

>fans or turbines in air tunnels
>benefits are having something to suck more air into that tunnel, air is "monetized" there with turbines - dual effect of having the turbine suck more air into the vent (from a large area, the vent a smaller area) for airflow and power.
let me draw the picture /sci/ - im a scientist, i like to ask questions.
