UV-C

Encouraged by articles showing that doing your laundry didn’t tend to kill all bacteria and also those stories of people freezing their jeans to cull bacteria, I started researching UV-C, the spectrum of UV light that doesn’t come into our atmosphere, and seemingly will kill most things pretty rapidly on contact.

Safety: Is key. this light will cause retinal damage in a matter of seconds and it’s not great for your skin. These reasons also mean you should avoid it with pets. You can wear protective eyewear, but more than likely some of your skin will contact the light depending on your bulb. Another aspect is that it quickly degrades plastics.

Applications:

The most hyped application is using this in your HVAC air handler to reduce mold buildup on your AC coils and potentially in your ducting. It is anti viral, anti bacteria, anti fungal, and anti plastic… but much of this is determined by duration; so air that is rapidly flowing past the light may not be as sanitized as still air. (though all of the surfaces immediately in contact with the light are).

A new concept that I was also intrigued by, was portable washing machines (such as RV use) these use less water and are perhaps more “innovative” or at least gimmicky. But, you can also add a UV light to the lid of a traditional (basin) washer easily. And the gyration should expose most surfaces to the light on top, but especially in light loads.

Finally, personal use. Which, I hope has made my pandemic life easier (if only because I bought this wand in late 2019 because my girlfriend travels with work and a peace of mind over bedding could be nice?) But this is a little AA powered wand with a UV-C bulb in it, and also with a float switch so that it makes it particularly difficult to shine in your own eyes. But, with a pandemic, and UV-C able to kill RNA viruses rather rapidly, I get some peace of mind by scanning common surfaces or light contact points quickly with it; a slow scan “may” be affective?

Coronavirus

I’m a little anxious, mostly about the changes to life for the future and how long these changes might last. How many events are being cancelled.

I’m a little bit anxious because I’ve been social distancing for the last week and a couple days. Some people still want to shake hands. How can I ask my waiter to not touch my cup every time i want a refill?

I’m a little prepared. I have seasonal allergies, so I have some air filters around. I happened to have started researching uv-c as a way to kill bacteria and viruses better than a washing machine (3 months ago – prior to this virus).

I can social distance. I have projects personal and work that require no personal interaction. Boat projects, car projects, technology projects. I can stimulate the economy by buying these.

Other thoughts; I need to get lettuce growing in my garden. Waterski is a good sport for social distancing, as long as you don’t load the boat with people (one of the more fun parts)

2020 Environment Action Plan

Inspired by Rachel Edelman, a post on Facebook

  1. Intentionally follow Meatless Mondays
    (This may mean Smoothies, Soylent, etc for lunches)
  2. Intentionally choose slower shipping on Amazon.
    (Even though I pay for Prime, at least they give me $1 digital items)
    (may also include grouping orders more intentionally)
  3. Intentionally offset my carbon from flying and boating though green charities
    (I did this last year with a donation to cooleffect.org)
  4. Be More Proactive About Recycling / Composting / Reducing
    1. Better Aluminum Can and Water Bottle Collection when visiting my parents (who live in a county without recycling)
    2. Research Composting my coffee grounds more effectively.
      1. Side Goal, make more cold brew for my gf instead of her Starbucks and Stok purchases
    3. More prep to increase effectiveness of recycling
      1. Removing Labels and rings where possible (Hi Milk, Stok Bottles)
  5. Shop at the Farmer’s Market / Locally More Often
  6. Eat More Veggies

2020 Decade Predictions for Driving

Inspired by Fred Wilson’s post.

US centric.

On Driving

  • Dashcams will become a larger necessity in the United States as hit and runs and underinsured motorists increase.
  • Level 2 autonomous driving will break 50% of the car market and likely every legally driven (see also insured) vehicle will be 1
  • Tesla likely to replace Chrysler (Fiat) in consideration of big 3 American automobile companies (with more parts made in the U.S. than Ford or GM)
  • Suburban and Urban jobs will increasingly telecommute as technology betters, rent increases, and traffic worsens (Atlanta, LA, San Francisco)

New Dampers on The E46

I bought my car used, with 123,000 miles on it and it has driven pretty well. It has survived track days, autocrosses, and daily driving in Atlanta.

Over the last two years though, I noticed two things:

  1. The car felt a lot like a go-kart
  2. Leaving garages or hitting speed bumps would sometimes bottom out the vehicle if I did not let the suspension rest.

Debating Between Coilovers and Stock Spring, Struts

I debated over buying a set of coilovers, Bimmeworld.com sells and supports ISC coilovers, they have a review in e46fanatics of surviving 5 years of heavy track use. And they’d be height, damper, and preload adjustable. And they are a Chinese import so they were the same price as…

What I went with, Koni Special Actives (formerly FSDs). I decided to go with these because, despite a willingness to track my car, mostly drive on streets. Tirerack has a great analysis of the special Active’s too, where they performed as well as the Koni Sports (a known good option), and were hypothesized to perform even better.

I also kept the stock springs, which had no signs of damage, partially because of ride height concerns. Having the factory ‘sport’ package means understanding that new springs will lower the car 3″ intimidating, but also unclear. And, performance wise, I just want that stock feel.

The Install

So, over Christmas, my shop mechanic (my father) and I bonded installing a new suspension. A task we’d done before on my 1989 Mazda RX-7 and he had done on his 1974 260z and 1999 Nissan Maxima. In all, the most of the work in the rear was removing the carpet — seriously, it took about 20 minutes otherwise bc they aren’t coilovers – and probably about 2 hours on the fronts (at a calm pace).

Based off of some suggestions, I spent a little extra on common wear items and some reeforcement plates. The stock sway bar end links that connect to the shocks are plastic and have a rubber boot; so the upgrade to a metal joint, an HD rod, and fresh rubber was obvious. The front and rear, but especially the rear strut mounts are known to wear out at the bushing, so I upgraded the rears to an American made aluminum and poly mount. The front strut sheet metal is also a known weak point – which I’ve countered on the front and rear with strut braces – but now I added steel reinforcement plates, basically big washers.

The Results

Well, I’m writing this post, and based off my introduction, you can probably already guess, but,

new struts are one of the best investments for a used car.

I say that, and even though I knew it from a similar experience in the RX-7; we start driving a new to us car and it feels okay, then it degrades slowly, but without objective ways to know it (oil leaking out of a strut, always bottoming out) it’s hard to know how much of an improvement it will be.

e46fanatics thinks that the stock 330i Sach’s struts start showing their age before 50k miles. And, on dis-assembly, at 170k miles, my rears were shot and running on the bump stops; the fronts were somewhat alive in those regards.

Now, my car doesn’t bottom out when leaving the parking garage bumps. It doesn’t squat when I accelerate. It shifts more smoothly. And it definitely corners at speeds better. And it feels a little bit less like a go-kart.
