installed capacity equals power. That amount of power either is or isn't enough to power the states of California and New Jersey. The "for a year" part makes no sense in this context.

The better wind conditions help, but offshore wind is really expensive. Transport and install alone for a big offshore turbine can easily cost EUR 1-2M. Add to that undersea cables, higher maintenance costs (salt water, difficult access) an

So disappointing journalists never understand the difference between power and energy. The opening sentences make me cringe so much I don't even want to read the rest of the article > Last month the American wind industry hit a majo

Do you have some sources? All windfarms I know of are designed for at least 25 years. Not many have reached that age yet, so if they last is yet to be seen. The first offshore wind farm Vindeby was decommissioned in 2016 (after 25 years) h

By far the most wind turbines have been built on land and for good reason: it's much cheaper. As long as there is space/not too many people complaining it makes more sense to build on land. Not sure exactly but on land installed w

I recently stumbled upon jExcel. I use it as an editable datatable that allows copy pasting to and from excel. That's what all my users end up doing anyway with any non trivial dataset, so might as wel make it look and behave as much a

I remember when my uncle showed me his Sony mavica. You could just take pictures, take out the disk and put in it your computer and the files where there. Viewing your own pictures on a pc was almost magical, as until digital cameras became

That sounds like home assistant icm with esphome. I flash all iot devices I buy with a firmware I trust (or at least is under my control) which is surprisingly easy to do with esphome. I pass a yaml file and a USBtty device to a docker and

Because of the cost of labour a lot of effort has been put into minimizing labour at the cost of capital (resources, automation etc). This again puts a negative pressure on wages as one would otherwise be automated away. By making labour ch

There is plenty of energy available from the sun in one way or the other, and there is no inherent harm in utilising that. So in my ideal tax system only finite resources should be taxed, primarily land usage (including use for agriculture,

If we would decide to tax raw materials instead of labour and income, repair would make economic sense again. Raw material usage is not sustainable as the resources are finite. Labour on the other hand is very sustainable, given enough time

Especially because before 1950 the Gros Michel was about as popular as the Cavendish now. And then it got wiped out by a fungus so instead of diversifying, all banana plantations collectively switched to Cavendish. Now there is a new fungus

Though it really depends on what you want to do with the data, I can really recommend to use esphome in combination with homeassistant/influxdb/grafana. You can configure the sensors with a simple yaml file, compile and upload to

That's not entirely true; slow (< 30 km/h) cyclists using the bike as utility to get somewhere almost never wear a helmet here. Spandex wearing speed cyclists almost always do though.

I'm guessing the cable has an esp8266 on board which you can get cheaply and is only a few mm2. It has WiFi and WiFi direct support and is powerful enough to run a webserver. Probably there are plenty chips that do the job, but the esp

Actually esp32's are quite fun and easy to program with micropython. Something like this project should be pretty straightforward and would arguably much easier than a pi. For micropython there is only the python code, no docker contai

Very nice article! Explores all the tricks I know of, and a few more. Never heard of the execute_values before, only a bit (3x in the example) slower than using copy but much simpler code.

For me the big advantage of doing more in docker and lees in the CIT environment is that I have less lock-in/dependency to whatever my CI provider does. I try to reduce my CI scripts to something like docker build docker run
