"...a watertight shell of a two-storey house built in 24 hours without a single builder on site — will be erected in California before April... It involves computer-controlled robotic nozzles which pipe quick-drying liquid gypsum and concrete to form walls, floors and roofs."

The inventor, Dr Behrokh Khoshnevis at the University of Southern California in Los Angeles, was at MIT a couple of years ago and I saw the presentation of his concept. It is exceedingly simple and elegant, basically a nozzle with a blade that shapes the concrete as it flows. I am surprised it took him only a year or two to go from concept to proof of concept.
