This is major issue in my experience. Even introducing new benign chemicals can lead to lengthy reviews and project delays. I've also found that when I've asked directly how to safely handle something the safety people don't

I guess, yes and no. Technically the scd41 emits IR, it just doesn't detect transmitted light, instead sound produced by the CO2 that absorbed the light.

PM2.5 have decent accuracy and are certainly useful at low price points, RH/temp work fine, particularly with separate sensors. Pressure works fine but is pretty useless. NDIR based CO2 (ex. Sensirion SCD31 or 41) also work fine. TOC i

You can just call outdoors 400ish, it doesn't vary hugely, or just take a bunch of measurements outdoors. Some sensors tend to zero offsets/drift periodically when they "detect" they are outside.

I build one with the SCD41, seems comparable, was a bit cheaper.

The south coast AQMD has a great website testing various air quality (mostly pm2.5) in lab and real-world situations against equipment http://www.aqmd.gov/aq-spec

I was trying to do this and the market seems terrible. I can buy a 10-12yr old car with 150k miles for >$10k (at least in models that I was looking at). Or stuff that is hard to maintain for $5k (which is what I'm already driving).

Rock Auto is great, definitely more consumer oriented and delivery is much slower, seems like professional mechanics rely on same day delivery. The biggest difference I see is that McMaster is curated, you want something there is usually on

Yah, you generally don't have to worry, need a ratchet, need a metal shelf, need an air filter, it's going to do what it's supposed to.

They are really fast to get back to you and will tell you what stuff is which can be helpful in certain situations where the material or vendor might matter.

You can get same day in some areas. We usually get next day in Reno.

Charging infrastructure is a bit of an issue if you can't easily charge at home or work consistently. Tesla supercharger network is good for long trips though, other brands lack there and you do need to change your long distance travel

Its also annoying when its the opposite, if I want to search for a car in California, I just stick myself centrally in Frenso and click all the adjacent areas since you can get SF, Sac, LA, Vegas.

Anguilla is a tourist destination, there is obviously stuff people want to do...

This is super annoying, I spend more time at work trying to find batteries, which we never have, than it would have cost to buy a legit brand name micrometer/caliper originally. Not to mention if you ever get it calibrated locally you

edit: I didn't realize this will apparently be required due to the antenna design in the iPhone, seems very cumbersome, you can't easily see where the satellites are... You don't really need to point it, at least with my inre

As long as its safe to occupy for permanent living it should get permitted, not sure how its much different than a hostel/rooming house-like arrangement. You don't need a kitchen and bathroom in your unit to live.

by s0rce 4y ago
That could be quite costly depending on the wiring locations in the unit and the total current capacity available. Personally as a renter in this situation I'd be pretty reluctant to pay for this unless its going to be saving me enough
559.
by s0rce 4y ago
Rental units also, the last 3 places I've rented have had driveways but no ability to charge an electric car, there just isn't enough incentive for landlords to install them yet, maybe if enough people start driving EVs people wil

Maybe ok if everyone drove them, I'd seriously consider it for my sunny commute in Nevada and parking all day outside in the desert. Unfortunately, everyone else is driving a massively oversized pickup truck and I'd prefer not to

I'm not sure what you mean, what cities in the desert near the central valley? Reno, Lancaster?

by s0rce 4y ago
I'm not so sure it would be a disaster (Societally, sure many farmers livelihoods would be disrupted...), would many food become unprofitably expensive or a rare luxury, yes. Would many farms be immediately incentivized to move to more

Very expensive, and its been done a lot already, see the various large projects in California to bring water from the Owens and Sacramento Valley to socal. There were various projects discussed to bring water from further away but its expen

This is a straw man, no one is suggesting to stop growing food on irrigated farmland but to focus on efficient irrigation and grow things more suitable for the limited water, see the suggestions from the SNWA https://s3.documentc

Those cities (particularly Las Vegas) are actually mostly quite water efficient. Its ag in the desert that is the issue.

by s0rce 4y ago
mostly no, although they do use wells but aquifers are drying up leading to salt water intrusion and subsidence. Further, most underground water can be more easily treated for drinking than surface water.

Beef also uses a ton of water, probably more than almonds.

by s0rce 4y ago
This is true at a fundamental level in that we need food to eat but there is a really strong argument that a huge fraction of the agricultural water use in the American west is not "useful" or at least should pay market rate. Exam

I think the best strategy is laid out for the Colorado basin by the Southern Nevada Water authority and could be applied across the American west, see the suggestions at the end with the first being the most important https://www

I carry a Garmin Inreach hiking/biking when out of cell service, personally I always have my phone so it would be nice to have it all in one, possibly with a slight loss in redundancy.
