This person has never heard of tavern style.

Slippery slope aside, I think reducing unnecessary consumerism would be beneficial for our most vuneral populations. There would be a lower barrier of entry into the economy and more resources would be available at a lower cost for people who cannot afford them

Stock price is not inherently tied to profit. That is why p/e ratio exists. Also different industries can have different p/e ratios. Not even this holds though. Tesla's p/e is OOM more than Toyota, but Toyota has higher profits and sells more cars.

In the prototype the dash had a marble pattern on it. Not sure if it was just a vinyl wrap or not. The production version has no marble pattern on it

Hate is a strong word.

Reddit has always had changes that made people want to leave. Removing CSS was the first that comes to mind. Now that lemmy exists it could be seen as a new platform to jump to every time reddit does something dumb or anti user. I have high hopes for lemmy

Hi, aerospace engineer here. As far as benefits go it depends.

If we assume the tube is constant volume and constant temperature. The ideal gas law says that in this case, the pressure would change proportionally with density. So if you lower the pressure by 50% the density should lower by about 50%.

Drag force is also proportional to density. So a 50% decrease in density will result in a 50% decrease in drag. This is true for subsonic speeds. The speed of sound is 343 m/s or 770 mph.

Drag also has a square relationship with velocity. So drag gets extremely high when there is an increase in velocity.

If we take the speed of the shinkansen(90 m/s or 200mph) as a baseline and lower the pressure by half. The new speed the Hyperloop would be able to travel with the new speed is 127m/s or 284 mph. That is faster 40% for the same amount the trains will have to work, but to build all of that infrastructure, spend all the money creating a lower pressure environment and maintain that pressure for thousands of miles is just not worth it. The vacuum tube is just not practical to make.

Edit: If you maintain a reduced pressure and increase speeds about 30% of the speed of sound, the subsonic equations I used start to be less accurate. But in that case drag increases dramatically in transonic and supersonic regimes.

Honestly, for growing places, or places with bad public transit, diesel busses are the way to go. They are the cheapest and require almost no new infrastructure so it can offset car emissions quicker than the other options. Established bus routes that are popular should be converted to tram lines or BRT.

It would be so wonderful if this is the last reddit hug of death

I am an engineer who works on turbofan engines, and the term ingestion is what whe use for all foreign objects entering the engine. That includes ice and birds too. Still an absolute tragedy.

I think many of them have a crippling addiction to reddit. Might be scary to think It could go away indefinitely. Not saying they are justified. Most angry/dumb comments on the internet are from 14 year olds, or people who desperately need to touch grass

A lot of this just feels like CEO talk. Obviously they do not want to back down but if enough big subs stay off then they might have to change course. I'm worried about the people who are addicted to reddit.
