Luke’s $10k A Week Blog

Surprisingly, the one thing I get the most attention for from the search engines is something I wrote one brief piece on, namely Raising Red Worms. Here’s all of my results. Note: anything with “10kluke” in it was just me checking.

I promised something more about nanotech and how it relates to space travel. Nano Space Technology is a cool page. Nanotech lets us create atomic machinery, such as Utility Foglets. It also lets us create really strong materials. The hull of your space ship could be a milimeter thick and still reliably protect against asteroids. But with a generous helping of Utility Fog, you could have a gentler bouncing effect, where the asteroid begins to slow down several meters away from the solid portion of the ship’s hull.

Today I am going to blog about utility fog. It’s the coolest nanotech idea I have ever heard of. And while it needs an assembler to begin with, it doesn’t have to be self-replicating, so we could use it without the risk of decomposing the world into grey goo.

The nanomachines used to make utility fog are called foglets. Their design is very simple conceptually. 12 little arms, each with telescoping action, side-to-side, and rotating capability, are connected to a central hub. When they grasp each other, they form an octet truss framework, which is very stable. (Think of the honeycomb structure, then picture it 3-dimensionally.)
