37x the warming potential per what? Per gram? Per liter? Or per mile traveled?

Because I'm pretty sure the amount of carbon dioxide exhaust released per mile traveled in an equivalent jet-fuel-powered plan is far more than 37x greater in mass than the amount of hydrogen fuel released by a mile traveled in this hydrogen-powered plane.

Mostly because CO2 is an exhaust gas generated by burning jet fuel, whereas hydrogen literally is the fuel in this case. And since it is the fuel, they probably try really really hard not release any hydrogen outside the combustion chamber. And combustion combines hydrogen with oxygen to form (mostly) H2O.

Released raw hydrogen is wasted fuel, which is something that aircraft powerplant designers try to minimize. Whereas CO2 is simply the exhaust that spews continuously from a perfectly healthy conventional engine.

Just yesterday I stumbled on this substack post about a research paper whose authors found that AI scored well on x-ray evaluations even when the AI took the test WITHOUT ACCESS to the x-ray images.

The moral of this story is that properly evaluating AI performance in classification tasks requires very very carefully designed tests, because neural nets are very very good at picking up correlations between the desired outputs and utterly unintentional signals in the inputs.

"....we sure do spend a LOT of time and effort trying to ensure every square theory fits into the perfectly accepted Einstein circle of truth."

We spend a lot of time and effort ensure that every new theory fits with observations.

The fact that our observations align very well with the predictions of General Relativity is another matter entirely.

How many different laptops and desktops does Apple need to validate their OS on?

And how many different laptops and desktops does Microsoft needs to validate their OS on?

Or really, how many different hardware companies bother testing last year's hardware with this year's update to Windows? Not just desktops and laptops but also GPUs and any other expansion cards.

Apple has it easy by comparison.

RealID, on its own, would not be sufficient under the SAVE act, because RealID is not proof of citizenship.

The "Enhanced Driver's License" version of RealID would be sufficient, because it IS proof of citizenship - however only 5 states offer the EDL version of RealID.

Are you deliberately spreading lies here, or did you fall for the lies?

If you fell for the lies, I encourage you to think carefully about who lied to you. And then, avoid believing anything else that they told you in the past, or will tell you in the future.

I stopped using Google search when I discovered Kagi.

It's subscription based, but it doesn't cost much.

This approach to monetization means that their only incentive is to make their service better for end users, whereas Google's primary incentive is to sell more ads.

The real "strategic mistake" was in becoming dependent on foreign fossil fuels (especially Russia's) for so much of the EU's energy needs.

Nuclear is just one of many ways to avoid that strategic mistake.

And Obama told them they were on a strategically stupid trajectory 12 years ago:
