Has this idea been discussed when drafting legislation? I mean are they aware of it but dismissed it for any reason or no stated reasons?

Can you link to a good article or post about this?

Thanks!

There are galaxies that appear to be free of dark matter and rotate accordingly. How does MOND account for that?

My understanding is that these observations are a fatal blow to any serious MOND models.

Definite risk of a monkey paw curling. But I assume he's less chaotic.

This is the truth. It would only take half a dozen Republicans to stop the madness now so the obvious question is why don't they?

The political system and elite institutions have failed their country. Does the US self correct with the next two election cycles? Hard to believe right now.

Last time I checked I’d have to leave my phone for a couple of days and the glue factor meant they wouldn’t guarantee it would come back perfectly. My assumption is this might make it a more trivial change.

Maybe. Maybe not. If my local phone and phone accessories shop can do it for little money in 15 minutes then the current calculus changes for a heck of a lot of people.

Just to add to your point; The final energy demand is much less than the primary energy we produce due to the energy costs of extraction, refining, transportation, and inefficient end use.

According to Kingsmill Bond (great name btw) on Dave Roberts' Volts podcast if we magically could replace all fossil energy with renewables today the final energy use would only be ~30% of today's final energy use.

"We’re pouring, from our calculations, two thirds of the primary energy into the air and wasting it." - Kingsmill Bond

OK fine but it's not really helpful to us reading your comment if you also don't back up your counter claim.

However it’s wired up the fact is the electric buzzing feeling goes away if you use a grounded extension cable instead of two pin.

Also got neither. I’m Irish but have lived a long time in Austria now. The punctuality thing is common with Germans. They have a different approach to rules here I think.

Would make a good tv show where a small group in a secretive TLA org started this but then made so much money they decided to keep it to themselves and get rich.

I would hate to live in that political system. Just imagining the ways it would be gamed and the billionaire press would leverage these votes makes me shudder.

So far the best modern improvement I’ve seen (and it could be further improved of course) is the increasing use of citizens assemblies.

I wonder if there will be a big enough market for a very compact smartphone equivalent device that can be used just for credentials? A device that is offline on standby except when you need it. Perhaps the size of a car key.

Not any more they don't. Those were older reactor designs which nobody wants now. And the 5 years was first-pour to switch on. Add a few years for planning, permitting and actually supplying to the grid.

Newly approved Korean plans are aiming for 2038. Best of luck to them. I'm sceptical they'll make it.

Edit to add:

They used to be pretty fast but like everyone else seem to be slowing down significantly.

You can’t put a gun to someone’s head, order them to be creative, and also expect good results.

New comment by jahnu in "Wired headphone sales are exploding"

jahnu — Sat, 14 Mar 2026 09:54:06 +0000

I tried the Apple one for a while but it’s badly shielded and picks up interference a lot. I mean really obvious buzzing sounds if near certain sources of RF. Switched to wired ear buds with a lightning connector and no interference issues. So I’m sad I can’t plug in my high quality headphones or hook up my phone to my mixer when I want without having noise.
