I have an inflatable ice tub from costco, and a large aquarium chiller. There is no literal ice involved, just a tub of water that is just above freezing temps. You can buy regular bags of ice and put them in a bathtub full of water, but th

Feynman was a uniquely gifted teacher that made things intuitive and simple. Those other books are course textbooks for physics majors, and they require an order of magnitude more effort and time to understand. When I was a physics student

Solids and liquids mostly don’t compress so as a general rule most can handle those pressures without experiencing any real mechanical stress, as they instantly provide a perfectly matching internal pressure that balances out the forces to

The comment you quoted was me paraphrasing what I saw as the implied idea that I was reading into the comment I was replying to. It's not what I personally suspect is going on here at all, but I can't dismiss it out of hand. Yes,

Ultimately, regardless of how one feels, you need to (will) maintain calorie balance in the long term, and cold exposure requires a higher calorie intake.

The paper you posted is just a review on autophagy and cancer that doesn’t contradict anything I stated. It is a mistake to conflate autophagy, calorie restriction, and cold exposure as necessarily biologically identical, which your comment

In the vast majority of Bay Area HOV lanes you cannot pay to be there, that only applies to fasttrack lanes, and in those you can read the occupancy setting of others cars on an overhead screen as they drive though. In both cases you can ea

It generally isn’t even possible or useful to pass on the right if people follow the traffic laws of keeping right unless passing. It becomes necessary only when people are illegally hanging out in the left lanes going slower than the norma

If white fat converts to beige fat, it is going to be burning a lot more calories, so you ultimately would have to eat more to maintain a stable body weight. It’s not clear to me that this would negate the benefit. If it does negate the ben

This is fascinating and sounds really promising. However, this article also seems to imply that frequent cold exposure that converts your own white fat cells into beige fat cells could be effective at both treating and preventing cancer. Th

You're gatekeeping being mad about a system that is asking me to decide between breaking a law/social contract, and wasting hours of my life every week while watching other people break it the whole time? No, I'm not mad abou

Really, the vast majority of them are, the fasttrack ones are in a few specific spots, but almost all bay area freeways have at least a 3+ only HOV lane.

The fines are already plenty high, it's just that they are essentially not enforced at all. You could definitely illegally commute everyday in a carpool lane, and expect to maybe get a $409 ticket between 0 and 1 times every 5 years or

Not really, it can save serious time if done properly and carefully in a consistent way on a long distance drive. Driving the length of California on I5, you can easily get stuck behind side-by-side slow traffic and spend the entire drive a

> Can’t you pay to be in the HOV lane? On a few of them, but not the ones I commute on and am talking about. If you do use one of the 'pay' lanes, it becomes free if you switch your fasttrak device to '3+' setting, an

I’m not sure that is true. I’m a fan of classic European cars and a 70s or 80s Volvo or Mercedes is still a reliable and practical car. It does not seem likely that current battery tech is such that current EVs will have full range on the s

I live in the Bay Area and hate HOV lanes. I can look over and see that more than half of the drivers are in violation, and yet it is effectively unenforced. It is a system that punishes people willing to follow the rules. Asking someone to

A quality car will last just about forever if you take care of it, Irv Gordon put 3.2 million miles on his 1966 Volvo and it was still in good shape at the end. But most people don’t maintain a car like that, however an EV has the potential

You can build a car interior that pretty much lasts forever, but it’s not cheap. There’s plenty of 60s and 70s Mercedes around with MBtex and zebra wood interiors that still look pretty much new after 6 decades of regular use. It’s eerie h

Battery swap would just about eliminate planned obsolescence in cars- EVs should last just about forever if the batteries aren’t impossible to replace. The only real wear items in an EV drivetrain are a few cheap bearings that already will

If I invent a hammer and make its design free, that doesn’t mean I don’t have a right to be critical or angry when people use it for murder.

Yeah, they do survive better with more long distance driving, but ultimately the newer common rail diesels are complex, fragile, and inefficient compared to the old TDIs. They succeeded in getting the emissions much cleaner, especially afte

A major factor if you actually are using it to get anywhere, because it’s likely not practical to carry more than a liter or so of fuel.

Yeah, they seem way behind, the fact that VAG (VW/Audi/Porsche) had 800v systems on production cars so many years before them is embarrassing for a company that being ahead of the tech curve is supposed to be their whole thing. Al

Four stroke engines are also quieter, last longer, and have lower emissions, but cost a lot more to make as they are much more complex.

Dunno why you’re being downvoted but I can’t think of four better reasons to not buy a vehicle, despite them being obvious leaders in EV tech, at least in the past.

Guess I was wrong, that’s a shocking engineering choice, that engine looks massive and heavy. A four stroke engine is about twice the weight and size for the same power output, but much more fuel efficient.

by _yb2s 10mo ago
Must have been two stroke, 4 stroke motors are too large and heavy for an application like that.

If the Volvo 240 is an example of elegant functional and minimalist design, the Tesla Model 3 is something close to the exact opposite of that- almost every aspect is sloppily ill conceived and overly complicated, with essential functions t

A good car design shouldn’t require any writing or screens at all. It’s not safe to have drivers read while driving, or to assume the drivers language. The vintage 80s and older Volvos I have owned, where just looking them over is a masterc
