The grid is not made of copper. You thought it was? Copper is for home wiring, if that. Up to that point, it's alumium, bundled with steel on major lines for tensile strength. Does it look like copper to you?

As for the article: grid operators don't build out grids on a lark. They do it to sell power, because they make money selling power. If people want to buy more power because they want to charge an EV, then that's more money available for them. EVs are a boon to grid operators. They're almost an ideal load. Most charging done at night, steady loads, readily shiftable and curtailable with incentives, etc. Daytime / fast charging isn't, but that's a minority. And except in areas with a lot of hydro, most regions already have the ample nighttime generation capacity; it's just sitting idle, power potential unsold. In short, EVs can greatly improve their profitability. Which translates to any combiation of three things:

1) More profits
2) A better, more reliable grid
3) Lower rates

    * ... depending on the regulations and how competitive of an environment it is.

As for the above article: the study isn't wrong, it's just - beyond the above (huge) problem - it is based on stupid assumptions. Including that there's zero incentives made for people to load shift when their vehicles charge, zero battery buffering to shift loads, and zero change in the distribution of generation resources over the proposed timeframe. All three of these are dumb assumptions.

Also, presenting raw numbers always leads to misleading answers. Let me rephrase their numbers: the cost is $7 to $26 per person per year. The cost of 1 to 5 gallons of gas per year at California prices..

Funny that to you, "Israel" and "Jews" are synonymous. As if all Jewish people unconditionally support all actions of the state of Israel, even those which are highly controversial within Israel itself.

This false synonymy creates an extremely harmful backlash. Stop doing it.

Ukraine is not free

Give me a list of Ukrainian prime ministers since 2000, and compare it to a list of Russian presidents since 2000 . Thanks in advance.

Even before the conflict it was the poorest and most corrupt country in Europe

This is not even remotely true. Ukraine's Rule of Law Index in 2022 was 0,50; contrast with NATO members Turkey at 0,42 and Hungary at 0,52. And its scores were dragged down by the consequences of the war in Donbas.

with a military second in size in Europe only to Russia (hence the poverty)

Ukraine's percentage of GDP spent before the current invasion was 3,2%, and that was *with* the ongoing Donbas conflict . By contrast, the US, at peace, spends 3,45% of its GDP on the military. For some European contrasts:

Azerbaijan: 4,5%
Armenia: 4,3%
Russia: 4%
Greece: 3,7%

Before the 2014 Russian invasion, Ukraine's percentage of GDP spent on the military was 1,6%.

ED: Just saw your second paragraph. But the things you speculate on are not exactly common on Titan, if they even exist on the surface at all (it's an icy crust ,not a rocky one). And either way, it'd be much easier with compounds other than methane.

And no, there doesn't seem to be meaningful amounts of nitrates in the atmosphere at least. You can see a list here. Nitrogen compounds are cyanide and nitrile compounds.

Metabolized with what oxidizer?

It's just the opposite - methane on Titan is like nitrogen on Earth; it's things like acetylene and free hydrogen that are the potential energy sources, and to a lesser extent the more common (but less reactive) higher mass alkanes, etc.

The main problem is that LAWKI isn't even remotely compatible with existing in the cryogenic environment of Titan. There are a lot of interesting alternative chemistries, but they require basically redesigning life from scratch. We're simply not up to this task with our current technology.

It's funny how we so strongly disagree further down in the comments, but I 100% agree with you here.

0,38g being largely fine for health is... I mean, if I had to bet, I'd put my money on it probably being true, but it's anything but guaranteed. There was a private project to test this, the Mars Gravity Biosatellite, but it ran out of funding; I'm not aware of any similar experiments that have been conducted. There've been a variety of attempts to simulate various gravity on Earth, such as having people lie on tilted beds or hanging them from cranes at an angle or whatnot, but they all have obvious weaknesses.

There's not just the question of adults who visit from Earth, but also children who grow up on 0,38g, and what impact that would have to their physiology.
