This animation shows a year of tides in San Francisco with the sun and moon:
I was inspired to create this after adding a tide forecast to a personal weather dashboard I have running on an old Surface Pro. I realized I didn't understand tides that much. I still don't, but I know more than I did before.
The animation illustrates four components of the tide. The obvious ones are the position of the sun and moon. When the moon is new or full the Earth, sun and moon are all lined up leading to larger 'spring' tides, which happen twice a month just like spring doesn't. As the moon waxes or wanes and becomes half full the moon and sun are at right angles and partially cancel each other out resulting in lower highs and higher lows. This is the neap tide, almost as unhelpful as 'spring'.
As orbits are not circles the Earth is closer or further away from the sun over the course of a year and the moon behaves the same way. When it's close than usual we get super moons and king tides (finally a type of tide that does what it sounds like). In the animation the sun and moon actually grow and shrink in proportion to their distance from Earth.
Here's how to read the animation. The date and time at the bottom of the screen refers to the tide right in the middle. The full screen shows the forecast running from 12 hours before the current time to 12 hours later. The vertical range is from -4 feet to 10 feet, relative to mean lower low water (MLLW), the average lowest tide over 19 years. The sun and moon are on a different scale - 360 degrees horizontally and 90 degrees vertically.
I've been meaning to check out the new Gimlet/Spotify podcast, How to Save a Planet, and finally listened to the first episode about wind power last week.
It was sponsored by the Infiniti QX55.
This is not even a hybrid. It's a 268 horsepower SUV. Consumer Reports says:
"The company cited 26 mpg combined (city and highway) when the QX50 was introduced for 2019. We measured just 22 mpg overall in our tests, putting it on par with larger, more powerful SUVs. And it required premium fuel. Subsequently, the official EPA estimate was downgraded to 25 mpg."
It's not even a particularly efficient SUV. You are really unlikely to be saving a planet this way. I'm not sure I can bear to find out who sponsors the second episode. I'm imagining a subscription panda steak service or bitcoin.
I shouldn't throw stones. I bought into a Volkswagen clean diesel (which came with a green tax credit before they got busted). I currently drive a Land Rover that can only hit it's claimed mpg if the engine stop technology is working. That only happens for about twelve miles after it has been serviced, which feels like the same sort of scam as the Volkswagen frankly.
My dentist overcharged the FSA debit card by $2.10 due to some mix up between expected and actual insurance payment. Which would have sorted itself out on the next visit, but apparently it's an FSA emergency which needs paperwork now!
There are at least 28 million of these types of FSA/HSA accounts in the US.
Life expectancy at birth has fallen to 681,995 hours. So assuming that on average each account generates two hours of needless admin per year this is the equivalent of killing 68 people.
Serial killers are pretty terrifying and justifiably get a lot of TV shows and FBI task forces aimed at them. But we'd save as many lives by giving FSA administrators 25 years to life every time they decide to reconcile to the last cent. And we should be watching Law & Order: FSA where the detectives drink to conceal the pain of uploading a PDF and explaining your situation in 500 characters or less.
Or we could save the time and money and lives and implement single payer healthcare.
"One in which we let groups of randomly selected citizens actually deliberate and govern. One in which we trust deliberation and diversity, not elections and political parties, to shape our ideas and to restrain our worst impulses."
This is very similar to what I've called legislative service, where a random jury of citizens would replace the Senate. In my vision you still have elected representatives who propose legislation and the panel of citizens acts to approve or deny. In open democracy you retain the benefit of a random selection of citizens presumably immune to corruption but they are debating and proposing laws as well. That's the gist I got from the interview, there is a book as well which I will read at some point.
Ezra raises some good objections, like voters feeling alienated from the decision of a panel that they didn't elect (less of an issue for legislative service than open democracy I think) and also the role of experts in the system (lobbyists as a positive force). I think he gets it wrong on California though:
"We have a pretty robust proposition process here. And I think the broad view is that it has been captured. Special interests get whatever they want on it whenever they want."
The problem is that Uber (or whoever) can pour money into marketing their proposition to the point where you feel you'd be letting down the puppy-saving firefighters if you vote against it (I'm possibly mixing up my ads here). With an adversarial jury style system you'd at least have a group of citizens looking at the actual pros and cons.
The interview is worth a listen, and I'll report back on the book when I read it.
