I am a huge fan of using this brush to spread Otter wax all over my favorite raincoats.
As temperatures drop its time to get ready for the wet. It has certainly already arrived elsewhere. One of my two waxed-cotton coats was leaking last winter. The sleeve started to absorb water instead of beading.
Heating up the wax and lightly brushing it on is cathartic. The results look better than spraying on Nikwax and last a lot longer. I also think the thicker wax helps protect the fabric, the Nikwax goes on near invisibly and the wax is a barrier.

On average, you consume between 74,000 and 121,000 microscopic pieces of plastic every year. Probably much more. Where does it come from? Read the rest
Bottled water is bullshit. Its production and transport to market are sucking the marrow out of our planet and the majority of the disposable bottles that it comes in wind up in landfills instead of recycling centers. Read the rest
The Hydroflask kept my daughter's water super cold during a baking hot road trip. I had a recyclable plastic water bottle and drank warm to hot water.
I usually don't buy into my daughter's fancy waterbottle addiction and stick with refilling empties. The Hydroflask stainless steel, double-walled, slip-proof water flask with a leak-proof lid is worth having! My kid put water and a few ice cubes in her lovely flask before we hit the road while I had frozen a Daisani waterbottle overnight. By noon I had hot water, and she still had cold water.
Then someone dropped a camera bag on my water bottle and a lot of my warm water escaped onto our camper van's floor.
I made my kid share her cold with the dogs.
I'm getting the 40oz version. She has a 64.

It's not just Amazon and Apple that expect massive taxpayer subsidies in exchange for locating physical plant in your town: when Google builds a new data-center, it does so on condition of multimillion-dollar "incentives" from local governments -- but Google also demands extraordinary secrecy from local officials regarding these deals, secrecy so complete that city attorneys have instructed town councillors to refuse to answer questions about it during public meetings.

Apparently, this story popped up back in 2015, but it's so cool that it's still worth reading about now: the city of Portland, Oregon has water pipes buried underneath of it that not only carry clean drinking water to the locals, but also generate hydroelectric power at the same time!
From Fast Company:
In Portland, one of the city's main pipelines now uses Lucid's pipes to make power that's sent into the grid. Though the system can't generate enough energy for an entire city, the pipes can power individual buildings like a school or library, or help offset a city's total energy bill. Unlike wind or solar power, the system can generate electricity at any time of day, regardless of weather, since the pipes always have water flowing through them.
The pipes can't generate power in every location; they only work in places where water is naturally flowing downward with gravity (if water is being pumped, the system would waste energy). But they have another feature that can be used anywhere: The pipes have sensors that can monitor water, something that utilities couldn't do in the past.
Providing power to partially operate water treatment and pump facilities during the day and then juice up streetlights at night: what's not to love about that? Read the rest
Collecting water from the air is nothing new. Fog nets—typically constructed using a sheet of plastic mesh hung between a pair of poles—are often used in arid areas to capture water vapor. The vapor condenses into a liquid on the mesh and is then drawn down into a collection receptacle. Boom: drinkable water. That said, the amount of drinkable water that a fog net can yield doesn’t amount to much and, as its name suggests, if it’s not a foggy day, there’s not likely to be much, if any, water collected at all.
Happily, for people living in areas that are dryer than a popcorn fart, a team from the University of Akron have devised a way to spin nanoscale fibers that will provide a huge upgrade over the conventional fog nets in use today.
From New Scientist:
They used electrospun polymers – a technique which allowed them to create nanoscale fibres. These are tangled around fragments of expanded graphite, like spaghetti around meatballs. The fibers provide a large surface area for droplets to condense onto, and the graphite encourages the water to drip out of the material when it is squeezed or heated.
According to the team’s leader, Shing-Chung Josh Wong, fog nets made using these new nanoscale fibres could harvest as much as 180 liters of water per square meter of material deployed, every day. Fog nets made using plastic and other conventional materials? They’re lucky to snag 30 liters of water during the same amount of time with the same square footage of material deployed. Read the rest

Scientists have been experimenting with "fog harps" in arid climates as an easy way to collect potable water from fog.
Via the paper:
Fog harvesting is a useful technique for obtaining fresh water in arid climates. The wire meshes currently utilized for fog harvesting suffer from dual constraints: coarse meshes cannot efficiently capture microscopic fog droplets, whereas fine meshes suffer from clogging issues. Here, we design and fabricate fog harvesters comprising an array of vertical wires, which we call “fog harps”. Under controlled laboratory conditions, the fog-harvesting rates for fog harps with three different wire diameters were compared to conventional meshes of equivalent dimensions. As expected for the mesh structures, the mid-sized wires exhibited the largest fog collection rate, with a drop-off in performance for the fine or coarse meshes. In contrast, the fog-harvesting rate continually increased with decreasing wire diameter for the fog harps due to efficient droplet shedding that prevented clogging. This resulted in a 3-fold enhancement in the fog-harvesting rate for the harp design compared to an equivalent mesh.
