A radiative cooling structural material | Science
using boiling hydrogen peroxide, these researchers reduced/compressed wood by removing the lignin, making an engineered wood with interesting properties, such as high strength. The kicker is that the white material is also a narrowband IR emitter tuned to dump heat to space through the atmospheric windows, so it can cool you in broad daylight.

Bioinspired polymeric woods | Science Advances
Hrm, interesting wood analog that is highly insulating and with better fire resistance. Specific strength is also interesting. Sorta foamy, like aerogel

Inyenyeri - A Rwandan Social Benefit Company
Seems to be a fan assisted rocket stove of sorts using a proprietary fuel. They give away the stoves, and sell fuel by the month. Is the fan powered by a thermoelectric rig?

Basically stripping lignin from trees to make an aligned fiber channel nannocellulose nanowood material, with anisotropic insulation properties. This spinout is marketing the stuff. Weird uses include blackening a top surface of an aligned block and floating it on a water surface, as a concentrated solar power receiver to make steam by capillary action through the aligned fibers.

Processing bulk natural wood into a high-performance structural material | Nature
So boiling wood in a sodium hydroxide/sulfide slurry to remove liglin and hemicellulose, then hot pressing the remains makes superwood that is as strong as steel due to densification of highly aligned cellulose nanofibers. Hot pressing also allows forming a final shape for engineered wood products.

KIRVES: Heikki Vipukirves
Apparently a somewhat better axe, though for serious wood chopping, you should probably get a low end 5-ton wood splitter for about the same price. Uses a down then twist motion due to shape and mass balance to enhance the splitting.

Denis Wood’s Dissertation – I Don’t Want To But I Will (PDF) « Making Maps: DIY Cartography
I Don’t Want To But I Will: Title Page of Denis Wood’s Dissertation Throughout graduate school I heard tales of the Denis Wood’s outrageous dissertation, curiously titled I Don’t Want To But I Will. Of particular interest are the scathing Acknowledgments, where Denis took his advisors to task. A worn copy of the Acknowledgments was…

Kebony - Home
Some kind of treatment process to effectively convert cheap/fast/plentiful softwoods into the appearance (and it seems properties) of hardwoods, which normally are long life trees that can't be grown fast. So, it avoids the need to cut down old growth forests, in favor of factory tree farms making trees quickly.

Open source house design building blocks, with the intention of parts being CNC milled for DIY assembly. Current it seems to be about milling stuff from wood or plywood for flatpack transport for semi-custom shapes then putting various modules together, but the probable end goal is 3D contour crafting concrete structures though.

Precer's Bioracer: Off-Road Vehicle Runs on Wood Pellets
A wood pellet furnace, stirling generator driven series hybrid electric ATV. I suppose this is for the semi-serious survivalist (I say semi only because if civilization collapses, it will be next to impossible to repair the thing should a critical electrical component fail, and the battery would fail eventually regardless)
