No, they are not. Here's some research for large-scale battery storage systems:
https://www.osti.gov/servlets/purl/1409737 Rround-trip energy storage efficiency is reported as 70% - 80%. Any crappy genset will match that.
I really don't understand this idea for a "hybrid" ship. What size battery would you need, to power the electricals of a ship for a sea voyage? What is the payback period to the shipping company?
fdsafdsfdsa | 3 years ago | on: Battery cost declines raise prospects of all-electric container shipping
The possible few percantage difference in efficiency between ship-based oil-powered generation, and land-based power generation, is more than wiped out by the storage and conversion losses of a battery-based system. It's also very expensive (and heavy). Why pay to fill a container with batteries, and then pay more to charge them, when you can be paid to carry a container of other stuff as cargo?

It's pretty clear that "smart chargers" will become "smart tax revenue generators" in the near future.

I think you meant "most".
The least efficient step is converting chemical energy into mechanical energy.
Given the cheapness of fuel oil and geneator sets, and the expense of batteries, what possible financial argument is there for doing this?

Would you have the same opinion if the maintainer announced they were going to stop working on requests originating from FB/Google/big bad mining corp/big bad animal testing corp/etc?

As you feel so strongly, I look forward to seeing what replacement for websockets you are able to create.

Facebook uses 6% the amount of power, as all bitcoin miners.
The amount of power consumed by all of the cloud services we unknowingly use almost 24/7 is a hugely underappreciated problem, I will agree there.
>Education is failing a big time
Indeed.

The only thing threatened by such things is the amount of time and money that devotees pour into them.

Depends heavily on what animal product you are producing. Obviously we won't be eating beef all the time. It also depends on what kind of farmland you have available, and what uses those crops have.
Where I am (Wales, UK), the combination of the farmer' lobby and the "Welsh culture and heritage" lobby has meant that largely unprofitable sheep farming has been subsidised, and what should be productive wooded hillside makes lamb that no-one wants. I'm not saying that raising animals is always the best use of land.

It's our demand for goods that is causing this.
fdsafdsfdsa | 3 years ago | on: Ask HN: Has YouTube peaked?
That brings me on to my second point - video is a HORRIBLE format for most forms of instruction (for me). Practically every time I decide to try watching one to learn something, it could easily have been communicated in text form. Coding is a great example - I really hate having to skip through a 10-minute video that boils down to a single screen's worth of basic code.
Saying that, I've saved myself a bunch of money watching youtubers who very generously give away their time and experience for free to show me how to disassemble and re-assemble electronics and cars.

I can only recommend this process, even if you don't make it all the way. I also appreciate that where I live, less of life has become dependent on smartphones and apps, and making these choices might have more sideffects on your life if you are somewhere like the US.
fdsafdsfdsa | 3 years ago | on: Ask HN: How to deal with children's online habits?
I've given up on the high ideals I used to hold about (online) privacy (and anonymity). There's an argument that they, in some circumstances, are the antithesis of personal and public responsibility.
My current plan is that my kids will get tech when they can afford it themselves. I'm also dreading it, as more parents bow to the pressure and allow kids to have phones and tablets at an ever-younger age. I do understand the downsides of this, and also don't want my kids to be social pariahs.
Also - you role model what your kids will do. If you think it's ok to sit and scroll on your phone at every opportunity, so will your kids. If you game till the early hours, so will your kids.
FWIW both my wife and I gave up smartphones last year, and all "tech" in the house is banished to our home office. When a family computer becomes a necessity, it will be in a shared area.
