Is it just for leisure or commercial traffic?

it's a lot smaller than I imagined. I can't picture a river barge fitting in it, but it's hard to tell the scale

Leisure only, there hasn't been commercial traffic on that canal for a long time: https://en.wikipedia.org/wiki/Union_Canal_(Scotland)

I know analogies are not meant to be perfect, but birds don't mass watch, and don't systematically watch every of your moves neither.

Quite. I don't see why we need this in a world that already has Kevlar, Dyneema and Carbon.

It seems to be more heat resistant?

This [1] article claims that the electricity from 115 strikes could power the entire US grid for a year, but it's surely napkin math. Awesome tech, though!

Secondary school physics teacher here: The article is conflating power (watt or joule per second) and energy (joule or kilowatt-hour), so any claim they make is nonsense and the article shouldn't be taken seriously. My students make the same mistake all the time but they don't get to publish it :-)

Power is energy per time unit (thus: energy = power x time), so while the power of a lightning strike is very high (~10GW), the overall energy isn't because it only lasts for a very short duration (apparently the duration of a lightning event is hard to define, [1] says about 0,5 seconds, other places mention much shorter durations, ~10us). So if that 10GW lasts for 0,5 seconds, the total energy is 1,4MWh, which is 1/6 to 1/10 of the electrical energy an average American household consumes in a year[2].

that article does not make that claim
nirse · a year ago
I think it does:

Right at the bottom under Frequently Asked Questions:

  How much lightning would we need to capture to power the entire U.S. electricity grid?

  Merely capturing the energy from 115 lightning strikes would supply all of the U.S.'s annual electricity needs.

Animals eat their disabled children. Humans should also do it then, since it's normal or natural.

Around 100k people die from age-related disease every day. I'd be careful to dismiss that as not a problem.

nirse · a year ago
I believe it would be a far greater problem if those people didn't die. Aging populations are a huge problem around the globe and unless we'd improve the quality of life to such a margin that octo- and nonagenarians are able to care for each other, I think we're all better off with people dying of old age.

I'm gonna go against this heavily tbh:

If you don't have a 'trusted wrangler' freelancers won't build anything worthwhile as they're not interested in the long term unless forced.

There must be somebody you know, or friend of friend, to get a warm intro to an experienced developer you can pay to oversee said team on an interim basis. No consultants, agencies etc. they'll fleece a non-tech like you, save your money and drop it on somebody good who can actually help execute your vision.

I work for a small company, around 10 devs. We've picked up quite a few projects over the years where a freelance team came in, built something and when the going got tough, walked away. That said, I've seen the same happen at renowned companies, so perhaps it's just an issue of generally people taking advantage of the shortage in experienced devs. I would aim to get some longer term stability, either by working with a company you trust through your network, or engage a tech Lead/CTO for a longer term who can oversee the contractors.

3-MMC is huge in Europe at the moment, never tried it but would be a little wary of it as I haven’t found a lot of reliable information on it.

This should be a reliable source on 3mmc, but it is in Dutch: https://www.trimbos.nl/aanbod/webwinkel/af1916-factsheet-3mm...

Iodine doesn't matter. You do have to account for the difference in weight/volume vs table salt though.
nirse · 2 years ago
I've read somewhere that the iodine can negatively affect the fermentation process, so that it's better to use iodine free sea salt. Cant remember the source, though.

Pro: cobalt-60 is really effective at getting rid of those pesky slugs and aphids.

Con: organ liquification and agonizing death.

A toss up really.

I do _really_ hate the slugs in my garden
