You can pyrolize the wood by cooking it in an oxygen-free environment, cooking off almost all of the nitrogen and other nutrients and leaving nearly pure carbon in the form of charcoal.
Off the top of my head, for a given amount of wood biomass, you can get about a 70% ratio of product to fuel if you use a high-efficiency wood fire to cook the wood itself.
Then you can take that carbon, bury it in decommissioned open pit mines, or use it as a soil additive (biochar), where it will sequester the carbon for thousands of years and act as a fertilizer.
You could also pair the biochar with a fast-growing swamp tree (willow?), re-incorporating the char into the areas around the willow plantation to create a sort of artificial peat bog which could also be useful for water storage and filtration.
Use 99% isopropyl alcohol. Add in a teaspoon of table salt -- it won't dissolve in the alcohol and will act as a mild abrasive to help remove stubborn residue. Rinse thoroughly with water afterwards.
If you're really serious about your cleanliness, a desktop ultrasonic cleaner is also amazing for cleaning bowls and downstems. You can get them for a few dozen dollars from Amazon and the like.
For one thing, it could delegate to a local service. Granted, the communication to this service is probably still be over a socket interface, but at least as a purely-local connection you would hopefully have some better worst-case performance characteristics.
This is basically what dnsmasq does when you use it as a local DNS cache.
I always thought it would be interesting if Spacex developed a "dragon utility module". It would launch in Dragon's trunk and consist of a docking port on one end, an airlock on the other, a miniature manipulator arm and a bunch of cargo mounted around the outside. After separating from the second stage the Dragon would flip around and dock to this module, which would give it all the extra bits needed for a mission like servicing the Hubble.
A heat pump could be used to cool the water to below-ambient and inject that heat directly into the outgoing compressed air. I wonder if a system like that would be more efficient than installing a separate refrigeration-based system downstream?
Even if the bad actors found the same nail polish to re-apply after tampering, the pattern of glitter flecks would be different. The recipient could compare a high-resolution photo of the nailpolish to a reference image to determine if the screw had been tampered with.
There are already some solutions around that try to address this on a consumer level. I recently watched a teardown for a piece of test gear that utilizes frequencies injected directly to the mains supply in order to control home hot-water heaters in Australia[0].
That's the great thing about standards -- there are so many to choose from!
I was pleasantly surprised when I started my first R&D job after university. It's just like a FIRST team but everything is bigger including the robots.
I don't think anything else in school has prepared me for the real world more than my FIRST team. If I could tell my younger self one thing, it would be to join the team in my freshman year instead of senior year.
