Comment Re:Wow.... who are the customers? (Score 1) 155

I'm a customer. I'm in the USA. Where internet is spotty outside metro areas. My house is in southern Vermont near the Mass border. SpaceX is great. ping time is much better than needed for serious gaming. No data caps. The second best service is HughesNet which costs about the same but has horrible pings - ip phone calls over hughesNet tend to have 2 second lag but at times is merely a half second. HughesNet has a pretty small datacap after which the speeds go down to 1-3Mbit/s. Not enough to watch an HD movie.

Third best option would be DSL.

SpaceX on the other hand is reliable, fast, and low ping. Love it.

I'm sure in Europe, the internet is much better and there is less usage of spaceX. But the USA has comparatively crappy internet compared to Europe.

By the way there are huge swaths of USA that are not eligible for spaceX because they are near their subscription limit in many areas of the planet. SpaceX is great about sending up enough satellites to keep the speeds around 100Mbit/sec during peak hours.

What's your budget? I just bought a new Bolt a few months ago. Love it. $25K including all fees except taxes. If your budget is $3K then I agree there isn't a huge used electric car market but it does exist (e.g. leaf's have been around for a while now). Note that you will save money on gas/electricity (amount depends how much electricity and gas cost in your area). Chevy is pretty good at making cars and electric cars are simpler to manufacture. Really it's all about the most expensive part - the battery.

Well tesla is relatively small. They are growing fast though but they sell about half a million cars per year. GM sells about 7 million. You make a reasonable point although I think Tesla *does* get credit for creating american jobs.

Also Tesla is about to open a huge "giga factory" in Europe. Which hasn't created a lot of American jobs.

Comment Re: 500 MW, enough to power 400,000 homes (Score 1) 243

Even if electric heat releases more carbon for now - to get to zero (average) carbon emissions we need to convert all homes and businesses to some form of electric heat (e.g. geothermal, heatpump or standard electric baseboard heaters) and then it's much easier to convert the grid to sustainable energy.

This is the current thinking.

Some towns/cities/counties have even passed ordinance/laws that all new construction has to use all electric heat (e.g. no gas or oil) but gas lobby has sued some of these tiny governments. It's much easier to convert all the power plants than every single business/home. So they think.

Comment Re:Suggestion: Yearly global 14-day lockdown. (Score 1) 307

I think there is indeed a way to do what you suggest. Your idea has some problems - one of which was mentioned: 14 days isn't enough because covid can go slowly from one person to the next within an apartment (think 4 room mates) or household (6 family members) but you can alleviate this with heavy testing. Or just ask people to continue quarantine if one in their household had symptoms until no one has symptoms for X days.

A second problem is that you can't halt everything. People have emergencies. Food needs to be trucked. Electricity and water needs to be delivered and produced. The more you think about it, the more exceptions you need. In our recent lockdowns, people at say Raytheon who just pushed paper all day were considered "essential workers" because they were a military contractor. So you have the problem of too many people considered "essential" as well.

A third problem is getting this passed as a law.

But still, with these problems there may be workarounds - or they may be "enough" to get things back down to reasonable levels for 6 months until you have to do another.

Here's my proposal. Make it a national holiday. Start small. Make it a 3 day weekend. Make it fun. Say "no travel". Start off with "all stores closed for 3 days". Try to get (or maybe you don't have to do anything) movies to come out that weekend on Netflix as everyone is "stuck home" that 3 day weekend. Blockbuster video games and movies can get released that weekend as they love to do that sort of thing with the bigger audience.

Slowly. Over decades. Turn it into something fun that people look forward to. Make it 4 days after a few years. Some people will just naturally extend it to a week. Call it "the home stretch" or something. Then when there is a pandemic you announce an off season "home stretch" for a particular date. Everyone will know what to expect, what to do, supermarkets will stock up, people will stock up, it's just something we do already but on a different date. It will be fun. Make the stretch 7 days instead of 4 or whatever. Get people used to this kind of thing.

We might not need to do anything next time as mask wearing is more acceptable now (despite some holdouts). Vietnam didn't have to do "much" as mask wearing was normal there. They would disagree - they had very very strict travel restrictions into the country and lots of testing but really, it was no big deal.

Comment 3 times larger than our sun? I think not. (Score 4, Insightful) 28

I think the article means "30X" not "3X". Typo? There are B stars and O stars. These are indeed blue but among B and O stars they can range from 3X to 90X the mass of our sun and any O or B star that is "six times hotter" than our sun should be more than 10X the mass of our sun.

How much is door dash taking? Do they really need more than one cent per delivery? Their costs should just be cloud server costs at this point. Why do they even need any employees? Maybe they have too much overhead.

I'm sort of kidding but also not. The whole business should be automated at this point and all workers can be fired (other than the drivers).

Similar with ebay, uber, etc.

I suspect they have a LOT of unnecessary overhead.

I seem to remember craigslist had one employee per city served. That sounds about right. Their costs are lower for their service as well.

Comment death rate going down - cherry picked data! (Score 1) 389

It took me a while to find a way to get the data to agree with the article but the first thing you notice is that before the article was published, UK had already surpassed Sweden. But more important:

Sweden death rate is clearly going *down*! There has been a long consistent trend.

This data is very cherry picked. Here is where I got my data:

Comment Trying to delay the starving mobs of destruction (Score 2) 251

I know a few people who live paycheck to paycheck and can not work from home. And a lot of them are pissed. Really pissed. Or scared. Soon many won't have money for food.

Please donate to food banks before desperation arrives. And volunteer if you aren't afraid of getting sick. You can even donate only to a local food bank by searching for one here:

Comment They give no feedback so they get contaminants. (Score 1) 172

They practically beg for contaimants.

There's no feedback. Never have they said what is okay and not okay to recycle. So they get crap. But I don't know what is okay and what is not. Is tape okay? Does it have to be corrugated? Are large staples okay? Pizza box okay?

We have a transfer station in our town. We separate and put different recyclables into different bins (huge bins). But there is very little instruction about what is okay and what is not. So they get "contaminants" as it is not clear what is okay and not.

Give people feedback and you can quickly get contaminants well under the 0.5% needed.

Comment On the other hand, salaried can do below 40 hours (Score 2) 381

For 15 years I worked for a company that also tried to get exempt people to work more than 40 hours. I took the logic and worked 37.5 hours. When asked what my hours were I got answers like "enough to get your work done". So I got it done in less time. Sure twice a year I had to come in on a weekend for some emergency (or artificial) deadline but on average I worked 7.5 hours a day (8.5 minus an hour for lunch). But I worked hard those 7.5 hours. I did good work. And my bosses all valued that. My bosses were always happy that I did more work than my colleagues and with a good attitude and with minimal oversight and I had good communication and didn't care that I worked fewer hours (although I kept my hours as quiet as possible). So... that "salaried" or "exempt" thing can work both ways.
