Re: TL9+ Wood [Ultratech]
Sheer strength is different from tensile strength and compression strength. The compression strength of densified wood is 50× that oak from what I can gather from the litersture, while the tensile strength and sheer strength are around 10× as much (inferior to Kevlar).

Minimalist furniture.
5 lb dinner table that can hold up a full dinner and the pressure of 5 adults leaning on it. Easier to move, less damaging to flooring, cheaper to ship. |

Part of the point of densified wood is that the resulting material is more isotropic. Indeed that's the goal of a great deal of materials engineering done on wood all the way back to the invention of plywood.

Re: TL9+ Wood [Ultratech]
Build some really big skyscrapers, and no I'm not joking, wood is actually something of a hot new material in building construction because it's lighter, cheaper, faster to build with, and more environmentally friendly then concrete. Buildings made with it also have a positive effect on the people living in them.

x5.5 is a big increase, but it doesn't give quite the results of a x50 strength increase in all directions.

Re: TL9+ Wood [Ultratech]
Wooden planks being 50x stronger for the thickness is a rather impressive feat.

It's 50x harder to split along the grain, but only 5x harder to split in the direction that people actually care about wood being strong in.

Also note that wood has, I believe, the same strength weight for weight as steel, so this makes that wood five time stronger then steel. |

Re: TL9+ Wood [Ultratech]
Even if that statement were true (as always, 'what kind of wood', 'what kind of steel', and 'what kind of strength'), the process makes the wood 3x denser, so weight for weight it's only 1.8x stronger than normal wood.

Q: Is it more energy/resource hungry than steel? If it can be bent, and it has a residual amount of spring greater than that of steel, IMHO it would be great for making the framing for chairs.
