Until then, keep riding. Cycling releases an order of magnitude less rubber dust than driving, and is distributed approximately according to population density on local roads/paths, not concentrated on traffic sewers/freeways.
On November 16th, Meredith Whittaker, President of Signal, published a detailed breakdown of the popular encrypted messaging app’s running costs for the very first time. The unprecedented disclosure’s motivation was simple - the platform is rapidly running out of money, and in dire need of donations to stay afloat....
Sorry everyone, I did try searching the lemmyverse for any previous postings of this article using “signal” in the search feature on my instance, but it turned up nothing at the time.
Like the title states looking for E2EE apps (Android and iOS) without going into much details or needs to be robust enough and easy to use for anyone and stable for operations that are susceptible to constant electronic warfare. I did some research and thought about replacing Signal with Molly and wondering if it will still work...
Hi! I’m over here on lemmy, and created this post as a link to your post. I don’t think there’s a mutually compatible way to repost/boost a mastodon post into a lemmy community, but this seemed close enough.
As per the quote below, a car loses about 0.08g of tread per km.
Compared to a car, a bike tyre is about the same diameter, 10% of the width (~20mm), 28% usable tread depth (~2mm), has 50% less wheels, and can travel 10% the distance (~10000km).
This suggests a (very approximate) tread loss of 0.08 * 10% * 28% * 50% / 10% = ~ 0.01g per km for bicycles.
For replacing longer car journeys less typically travelled by bicycle, rail transport is the best solution and removes the issue of tyre wear.
Using the same assumptions as above (215/60R16 tires, 7mm of tread loss over 100,000 km), I estimate the loss of tread by volume from each tire as follows:
Cylinder with a diameter of 664 mm and a height of 215 mm has a volume of 74,412 cm3. Cylinder with a diameter of 664-(2x7)=650 mm and a height of 215 mm has a volume of 71,307 cm3. The volume difference between a new and worn out tire is 3105 cm3.
Typical land to sea ratio of tires is 60-70% land, depending on the type of tire. If we go with an about average value of close to 65% tread, we get the lost rubber volume of about 2000 cm3 or 2,000,000 mm3 over a single tires lifespan.
Each revolution of a tire loses about 0,04 mm3 of tread, which, according to Wolfram Alpha, is a bit less than the volume of a medium grain of sand.
If we look at the entire car with 4 tires over a kilometer of road, we get 80 mm3 or about 0,08 grams of tread lost per car per kilometer.
Following the “unprecedented price rises” in the past year for retail electricity rates across Australia, it looks like we have some “unprecedented price drops” just around the corner!...
