confused about dwc and bubblephonics

is a bubblephonics system both a drip and a dwc system combined?

if so this is what i'm going to buy/make.

like his one http://www.stealthhydroponics.com/product.php?xProd=16&xSec=34

Yeh looks nice.But i never grew plants so close to each other,it should work good for clones,or main cola plants.
