The incentive for all parties (except the patients) is to increase revenue, rather than decrease costs. Insurance companies may want to reduce costs on a case by case basis, but on a macro level they want to spend more, since they are requi

The pollution problems with bunker fuel are primarily local and short-lived, however, whereas CO2 emissions spread through the entire atmosphere and stay there for a very long time.

I think that might be confirmation bias. The people who happily retire and have the freedom to do whatever they want are less likely to talk about it on a forum; they'll just go live their lives. Conversely, if a person banks all of th

Yes, it can, although I can't be sure it will work at 500 mph. They tested it with a C-12, which has a top speed of 338 mph, and were able to transfer data at 610 Mbps. Source: https://spacenews.com/spacex-plans-to-star

If something hasn't happened yet it indicates that if it does happen it will happen later. For example, since pigs haven't flown yet, if they do fly, it will have to be later. Seriously, though, I think the researchers were trying

The thing that makes meth heads and crack heads dangerous is primarily that the users are desperate for money to feed their addiction and thus more likely to commit crimes to make money. Coke heads probably started out fairly wealthy, since

One big difference is that these EVTOL aircraft are small enough that they can use ballistic parachutes for an extra degree of safety. They usually also have more redundancy due to distributing thrust between many small electric motors. The

Well, it's not a lose lose situation to the people that don't own property yet. They would greatly benefit from housing costs dropping, since they could afford to buy their own house or pay less in rent. The problem is that the pe

You could also say it's the same reason asylum seekers and immigrants are called illegal aliens. It's still politics, just in a different direction. Framing something as a moral problem is not necessarily bad; it just has to be a

Part of that is the sheer volume of those books that were sold. People throw away more copies of Hunger Games in a day than many books will ever sell until the end of time. Like the anecdote about Pablo Escobar losing 2 billion dollars ever

The potential upside for Tesla is huge. If they can become the Apple of electric cars and if electric cars become standard, they could be worth trillions. The reason their valuation was not in the trillions is because there is a risk that

I don't know enough about Kissinger to have a strong opinion about him, but I think the idea is that Kissinger got away with a lot of awful stuff because he was responsible for a lot of horrendous things done to other peoples. If Hitle

Grinding rocks to 200 mesh (74 microns) takes about 20 Kwh per ton. Using 100% coal electricity that would lead to 20 kg CO2. Transporting a ton of cargo by truck 200 km creates about 22 kg of CO2. Basalt seems to remove less CO2 per ton th

A couple points: 1. These numbers are from a 2015 report that was probably prepared in 2014 and calculated using data from several years before the report was written. Solar tech has improved a lot in the last couple decades. 2. The graph

Government does not always mean nation states. In this context I believe it is talking about regional, feudal government for the most part. As for companies, the corporate structure may not have been developed yet, but there were guilds, pa

It's almost always cheaper to overbuild renewables than to use seasonal storage. Seasonal storage is used once a year, so if you can store a Kwh of energy for $1 it still increases the cost of the stored electricity by 4-5 cents per Kw

The problem with generating power in the Sahara for use in Europe has little to do with transmission losses and much more to do with the capital cost of building high capacity power lines over thousands of kilometers. There's also the

2,116 officers were assaulted with a firearm, but only 6.1% of those 2,116 were injured in the assault. That's approximately 129 firearm injuries. That means the rate of non-fatal firearm injuries is approximately 16.1 per 100,000. In

Beginning January 2020 ships worldwide are required to burn fuel with less than 0.5% sulphur or install scrubbers, so the problem has been greatly reduced. It's still way worse than regular diesel, but it's much better (about wher

It kind of is an unbelievable concentration except in certain exceptional circumstances. A 0.1% concentration by weight for just the first 30 cm of topsoil would require about 5 tons of microplastics per hectare (or about 2 tons per acre).

Thank you so much for posting the source! I don't understand why so many reporters write an entire story about a survey or scientific paper and don't link to it or even mention the title of the paper.

Starship will launch into orbit well before it is considered safe. If it reaches orbit this year it will take at least 5-10 more launches before they put cargo of any value on it and at least a hundred launches before they put humans on it.
