Power to ports is the least of my worry - that is cheap to build compared to all the other costs.

Charging on diesel doesn't make sense though. It makes more sense to have a 'tug boat' with engines for those trips and then it can do something else (what?). Can an existing ship (either cruise or cargo) tow this across the ocean on need?

in the end though my question is can batteries large enough fit on a ship. Everything else is logistict we can figure out but batteries are not energy dense. Ships have a lot of space (and need ballest weight on the bottom), but is there enough?

Most of the time a cruise ship is only going to move as far as it can get in a night. The sales pitch is you get to see a different city every day. There are a few places where the ship wants to be during the day (some glaciers are beautiful from the sea), but most of the time the customers plan on walking on dry land every single day, just in a different city. Thus they only need enough to get to the next port. Most transatlantic cruises sell at a large discounts because most people find the idea of spending a week on a ship not interesting (there are exceptions).

As such it is believable that most cruise ships could run on battery most of the time, and only need generators for crossing the ocean. That is very different from your typical cargo ship that is crossing the ocean on every trip and so needs a lot more energy. Of course believable is very different from reality, batteries are not very energy dense, and so it isn't clear if it really can work or if this is a press release that will fail when real engineers (or the real world) get involved.

That is a headline yes. However I have not been able to trace it down to anyone who is independent and has looked at what it really means. There are too many ways to cherry-pick numbers to make a point. I don't want headlines, I want someone who understands traffic safety and how to work with numbers to do an in-depth analysis. This is hard work, and so far it is missing (except as done by the self driving companies and thus biased)

"reiterates that “59 people have been killed in over 3,000 crashes involving Tesla’s self-driving software in the U.S. since 2021 alone”

more than 42,000 people were killed on the road in just the US alone, almost all by human drivers!

The real need is not perfection, it is at least as good as humans. Better than humans would be nice. Don't be fooled by statistics, they can be manipulated to say whatever you want, and it isn't just Tesla doing it!

Sadly even though I'm sure data exists I've never seen anyone independent publish anything trust worthy on how self driving compares to humans. All I've seen is data from someone with obvious biases. (they might be right but they still have a bias and so need independent analysis)

Some Easter cease fire. No point in negotiations at all when we can't trust them to mean anything.

Claude is very good when driven by someone who knows how to do the job and demands perfection. However if you give it a prompt and take the first result it is normally junk, make it iterate and things get better.

don't label with panel slot - too often you need to move things and so those are incorrect anyway

the box needs to be accessable. The drop ceilling counts but something perminant ceiling would not.

Rotating passwords are less secure pecause people chorse a short password and then append an incrimenting number. Thus if it leaks for any reason the attacker knows them all.

If you only force rotation after a known breach (that you admit to) people choose a new - good - pasword. Make sure the source of the breach is fixed though or people will give up when it happens too often

i set things up so I'm close to net zero, owe the state a tiny amount, tiny refund from the feis. There is no hurry, but I want them done late March just in case there is something weird I need to figure out (which has happened a couple times over the decades I've been eoing them.)

As a parent, most of the worry is just unreasonable fear. If you want kids have them. Sure they are expensive, but they will take so much time you won't be able to do a lot of the other things you were spending money on before. I find it well worth the costs (this is of course a matter of opinion)

The printing press is a very new invention in our universe. Before then books were for the rich. Often too history is written by the victors and so it missing a lot of important details that might or might not matter.

Come to think of it intelligent life such as could write books seems to be new. (but we have no ability to detect life elsewhere if it exists so who knows)
