PacSci-Doku: “Futuristic Home”

By Dennis Schatz – Senior Advisor

Do you Sudoku? It’s one of the hottest number games around! Well, here’s a twist we think you’ll love. We call it PacSci-Doku. Can you guess why? Here’s how it works. Instead of filling in the blanks with numbers, we use letters. Hidden in one of the columns or rows is the answer to a science question. You’ll find information about the answer on the answer tab below.

The question in this edition is:

How might your house be built in the future?

To find the answer, complete this PacSci-Doku using the following nine letters:

I  E  D  d  T  3  N  R  P

The Answer

PacSci-Doku: Futuristic Home - AnswerThe question in this edition is:

How might your house be built in the future?

The answer: 3D Printed

Imagine a two-story robotic arm with a large nozzle on the end. It slowly moves in a zig-zag motion to extrude a mixture of cement, biopolymers and straw. Once the material hardens, it will withstand hurricane-level winds, and construct a house in less than a month at a fraction of the cost for traditionally built homes. This is the vision of a number of companies now building 3D printed homes. Last year, an Austin, TX, company – ICON – built a 350-square-foot house, completing it in 47 hours for just $10,000 in building materials. ICON is now working on building an entire village.
