Biosecurity and a return to normal

I’ve been hearing a lot, lately, about the “return to normal” — what do you most want to do when we return to normal, when do you think we’ll be returning to normal, what changes do you think they’ll need to make before we can return to normal. And the questions strike me as wrong-footed. Especially as Trump and Pompeo talk about SARS-CoV-2 coming from a lab. Now “came from a lab” doesn’t necessitate malicious intent. The fundamental, longstanding problem I’ve had with gain of function research (the reason I wasn’t at all upset when the Obama administration put thought into the cost and benefits of this research and subsequently dropped government funding for this research and I didn’t think it was a stellar idea to resume funding) is that biosecurity is so difficult. And the spread of this virus highlights how vulnerable we were.

Sure, nation-states have forsworn biological warfare … but that’s not everyone. This release was probably accidental. I don’t say that because of any insider knowledge, but if I wanted to release an infectious disease … I’d have done a better job of infecting people. Get some infectious people at the Super Bowl – eating and drinking downtown, riding the public transit system, walking around the stadium. Or send people to ride mass transit in a few major cities – spend a day riding trains through Waterloo station, a day milling around Grand Central. If there are suicide bombers willing to literally blow themselves up for the cause … it seems like they’d be equally willing to inject themselves with some infectious disease. And the border agents can search whatever they want — the easiest thing in the world to ‘smuggle’ into a country is your own bloodstream. No explosive or drug sniffing dog is going to notice, no aeroport scanner will see anything because there’s basically nothing to find. Unless this is malicious intent with the forethought to make it look accidental (or a different actor framing the ‘obvious’ culprit) … it’s accidental.

The fact no one has done it yet is rather amazing. We’ve demonstrated our susceptibility to biological attack. We’re in the middle of demonstrating our unwillingness to take actions to prevent the spread of a disease. I absolutely believe this is an attack vector that will be exploited in the future. So why would we want to return to the previous “normal”?!

Energy Usage – Update

We’ve been tracking the energy draw of our various appliances since getting our geothermal system a few years ago. It was great to see the diminished usage with the geothermal system, but I’d like to reduce our usage farther. Not just to save money on our bill and reduce our impact, but reducing our draw will reduce the number of solar panels we’ll need to support our home.

The items we’ve audited so far account for 88.46% of our energy usage in the past year — the oven, cook-top, microwave, bathroom exhaust fan/heater, lighting (we installed LED bulbs several years ago), and misc small plug-in devices (tools, small appliances, laptops/tablets, phones) are 11.54% of our usage. While I’ll certainly make improvements wherever possible … I’ll see a bigger savings cutting the septic aerator usage in half than completely eliminating the untracked draw. The biggest savings comes from investigating the top of the list.

HVAC is still our biggest draw. We’ve dropped the temperature rather significantly in winter without seeing much decrease in usage, so just changing the thermostat isn’t a big win. I’ll be building a thermal imaging camera with a MLX90640 IR sensor — it’s a cool toy, and I’d be able to identify thermal leaks. Unfortunately, I picked a really bad time to look for thermal imaging bits. All of the temp checks we’re seeing to identify coronavirus infections? Thermal imaging everything is on backorder. I put my order in, so I’ve got a place in the queue.

The water heater … I’m going to spend more time investigating why our desuperheater doesn’t seem to do much. We’ve seen savings in the winter — when I’d expect to see the least benefit from the desuperheater — and nothing in the summer. I want to research insulating some of the water pipes and installing heat traps. And we’ll finally purchase the “smart” controller that hooks up to the WiFi and lets you drop the set-point on a schedule.

Next largest draw is an old refrigerator — that’s an easy change. We’ve got a newer unit that needs some repair. One year of energy savings will just about pay for the part, so it makes sense to retire the old fridge and bring the broken one back into service.

Those changes, plus fully shutting down the old server, should reduce our power consumption by about 4,500 kWh/year — a 450$ savings, and a significant reduction in solar system sizing.

Item kWh/year
HVAC 4932
Septic 4668
Water heater 2676
White refrigerator (1989) 2250
Car charging 1164
Black refrigerator 1134
New server 1103
Dryer 245
Family Room TV 144
Dishwasher 118
Bedroom air filter 61
Water pump 53
Washing Machine 30
Downstairs bedroom TV 12
Raven charging 7

And, hopefully, we’ll finally hit the ‘efficient neighbors’ line 🙂

Protesting the Protests

There are some people protesting the stay at home orders – I see videos from outside of DeWine’s daily briefings, and several other states seem to have similar problems. Apart from the question of astroturfing, problem is that there’s very little opportunity for counter-protests. When you go to DC, there are PETA people counter-protesting the people looking to fund medical research (animal testing). There are vegans counter-protesting people looking to increase subsidies in the meat industry. I’ve never seen an abortion protest that didn’t have both sides represented.

These ‘liberate us’ protests? These are people who don’t think they should have to stay at home – they should allowed to hang out at bars, eat in restaurants, shop, party, and … oh yeah … crowd together at protests. The people who think the stay-at-home and shelter-in-place orders are important to protect their health? Seems like a far smaller portion of them would be willing to hang out in Columbus in a protest. Even if they could find masks and whatnot.

Why drive somewhere nonessential? Your car breaks down, and you’re exposed to others (and exposing them to you). You get into an accident and you’re exposed to others (and exposing them to you). Get injured in the accident and you’re adding to the patient load at hospitals. We’re not just staying at home to avoid large congregations. We’re staying at home to create less load for emergency personnel.

Visualization: Percent of Population Infected with SARS-CoV-2

Updated graph for current infection numbers

And the states kinda like Ohio graph where I still think “distance from NYC” is a pretty significant factor in how many individuals are infected. Ohio, going on a month of kids out of school and entering week three of the shelter-in-place order, isn’t seeing the exponential growth some states with similar population numbers have encountered.

Reopening

I keep hearing Trump talk about his decision to re-open the country (and how it’ll be the biggest decision he’s ever made). Begs the question how. And I don’t mean “what is the plan to resume somewhat normal inter-personal interactions” (although the process question needs to be answered). I mean procedurally how is he going to *open* the country? He’s never closed it! Individual states have enacted various protective measures as they see fit. He really think he can overrule, say, Ohio’s shelter in place order? Issue an executive order mandating we all eat at a restaurant this weekend and … what? The FBI is gonna haul me out of the house if I don’t?

Dandelion Lotion

Anya has been loving collecting dandelion flowers this Spring. A few years ago, I made a dandelion soap that we’re still using. She wants to make more this year since we’re running out. We started the oil infusion for the soap, and she wanted to collect more dandelions. I’ve seen a lot of recipes for dandelion lotion/salve … so we made some. While the oil infusion for the soap is just dandelion heads in coconut oil sitting on the heater vent in a sunny window for a few weeks, I wanted to make the salve today.

We combined the coconut oil and dandelion flowers in a pot and simmered it over low heat for an hour.

Filter the plant material out of the oil and return it to the pot. I added a little bit of beeswax and a few tablespoons of cocoa butter and heated again to melt the additions. This was poured into glass canning jars.

Once it cooled, we have a bright, sunny yellow lotion with a mild cocoa scent. Anya has been using it daily.

Trump Impeachment / SARS-CoV-2 Timeline

The timeline below was posted to a FB group today, but I wanted a more visual format to show how much nonsense  the “impeachment was a distraction from this serious pandemic business” story is. I cross-referenced dates in the timeline with the number of US SARS-CoV-2 infections using archived data from Johns Hopkins through 23 March and the dataset from COVID Tracking (which is current but doesn’t go back far enough to provide correlation with the impeachment dates). There is some overlap, but it’s not like Trump was completely focused on impeachment activity before 05 Feb. Campaign rallies and golfing were his choice distractions. Both of which continued well after the impeachment trial ended.

Is it helping?

Schools in Ohio have been closed since 17 March (and a lot of districts stayed home on 16 March). Restaurants have been in delivery and carry-out mode for about the same length of time. We’ve been under a stay at home order since 24 March. And the important question is … is it helping? That’s a difficult question to answer because epidemiological predictions have very broad ranges because most of their inputs are so unknown … and the limited testing makes the data being compared wildly inaccurate. But we’ve only got the data we’ve got, so I thought I’d run some comparisons to see how Ohio is faring.

I selected the four states closest to Ohio in population — PA, IL, GA, and NC. Because these states all identified their first case well before Ohio, I added CT because the first case identified there was 08-Mar and Ohio’s first cases appear on 09-Mar.

State 1st Case Population
PA 6-Mar 12,801,989
IL pre 4-Mar 12,671,821
OH 9-Mar 11,689,100
GA pre 4-Mar 10,617,423
NC pre 4-Mar 10,488,084
CT 8-Mar 3,565,287

It looks like our curve is flattened — although North Carolina, where the first infection was identified earlier than Ohio and their their stay at home order was issued on on 27 March, has identified a thousand fewer cases as of yesterday.

Is proximity to NYC a major factor? CT and PA (as well as NJ, which has a relatively high number of cases) are all right there. But Georgia and Illinois are farther away from NYC than Ohio. Is the number of tests a factor in these case numbers? I’d expected a higher correlation between the number of identified cases and the number of tests administered. GA and CT have fewer total test reports (positive + negative tests) and have more infected people. NC has more reported tests, but fewer cases than OH. PA and IL have more reported tests and more infected people.

School’s Out — Books

Well … it doesn’t look like school is going to resume until, possibly, August. Maybe not even then. Our district’s go at distance learning has been quite lacking — they’ve basically taken three weeks off to (hopefully) sort out some content to complete the year. I wanted to get Anya a bunch of books — she doesn’t enjoy e-books in spite of the fact we’ve got an endless supply from the local libraries. She likes physical books. I do not like blowing fifteen or twenty bucks on a book … so that’s not going to work out well 🙂

I remembered Book Outlet, where I got her Lucy and Andy books (they have a referral program – 10$ off your first order of 25$ or more and I get a bonus 10$) — I went through their entire collection of not-yet-teenager books and ordered 43 books for about 150$. That’s about 3.50$ per book, mostly hard covers. There are some reference books, drawing instruction books, science experiments, maker ideas, programming books, and a lot of fiction books to try out. I even found a book about urban animal rescue — she’s rather enticed with the idea of being a vet and rescuing wild animals. This will be a great supplement to whatever the school puts together for the remainder of the year. (I also picked up a 2nd and 3rd grade curriculum — additional work for the remainder of this year and something for the summer).
