I'm running hister locally, I see in the MCP docs that a third party can query the server, but is there a way to import data as well? I find that I often do research using pi, and would love to save the context to hister to query later on. The closest thing I see is the "hister import file" command, which is great, but inconvenient. If MCP allowed third parties to dump text data in, that would be ideal.

I did some more research, and it looks like tires are the 2nd largest part of the pie in terms of single origin. The largest is textiles which are 35%.

The AirGradient uses the D1 wemos as the microcontroller & network connectivity. There are D1 ethernet shields that have PoE that would make it pretty easy to slap on top of the d1 and provide this exact feature, however you might need to tweak the code a bit to switch the network access from wifi to ethernet.

I've read that the majority of microplastics come from tire wear (national geographic quoted 28% of the total), and because there's no good alternative to wheel tires, it's unlikely we'll see a decrease of pollution here. So even if we found an alternative to bottles, plastic bags, clothing, etc, it still won't make a dent in pollution unless we convince the world to use a form of public transit that doesn't make use of plastic tires.

We could reduce human consumption of the particles if we only consumed lab-grown meat & hydroponically grown vegetables where the water is ultra-filtered before use.

Do you know what happens to explosives on sunk ships generally? Are they usually left at the bottom of the ocean, and could they have the potential to detonate?

Sadly most popular window a/c units don't have true heat pump abilities. Usually the heating portion of window units use resistive heating.

Why would it be the fault of hospitals? They have no incentive to construct more ICUs. A large percentage of covid patients entering the ICU for ventilation will die, and you can't collect on a dead patient. ICUs are a money hole -- they require specialized equipment, isolation construction, experienced medical team, etc. If a hospital is motivated by profit, they would construct as few ICUs as legally possible.

Nurses working in the ICU during the beginning of the pandemic would use the same mask for an entire week without losing efficacy. If the masks didn't work, we would have seen a huge number of them infected in the NYC hospitals but that didn't happen. Most viruses don't survive very long on surfaces.

you can reuse n95s, nurses do it all the time. let them sit near a sunny window, off-smells will dissipate in a day. each mask is good for around 8 hours of continuous usage, but it's likely that the mask becomes too soiled before the electrostatic charge is neutralized.

also could have used a worm drive gearbox, they also have high torque, and possibly a rotary encoder for sensing position.

Once we figure out how to repair the tooth enamel properly, there will be no need for fluoride in dental care. We're still relying on epoxies & other glues.

With such a small amount in tap water, it seems like it would be hard to conduct a controlled study.

Yes, it seemed like it worked in hamsters, but as we well know, most drugs that work in mice don't work in humans. Besides, we already have many anti-inflammatory drugs that can reduce the cytokines, so it's a stretch to use ivermectin strictly as a steroid.
