And also the founders. Some of them loved the idea of a militia instead of a standing army. There was even an attempt at a militia navy. Which is insane. "Got my musket and rowboat. Off to defend the homeland!" rows towards French 90-gun ship.

The whole idea behind a militia was barely practical back then, and isn't at all with industrialized warfare. If that's the argument for the 2nd A, then it might as well be tossed on the same pile as the 3rd A of "anachronistic stuff that made sense to somebody at the time".

Nah, it's a small round as rifles go. "High powered military rifle" is a complete misnomer.

Not soon enough.

Some combination of pyroxene and silicium is typical. Fire containment blankets aren't new, but this is a new form factor in a package convenient for one or two fire fighters to cover a car safely.

Not sure how much it'd improve ebikes. Maybe if you want to take a bike trip longer than 100 miles.

If anything, sodium batteries are more exciting for ebikes. They're more than enough for getting around town, and they're cheap.

The number is zero gallons, or sometimes very little.

Trying to put out the self-oxidizing reaction of a lithium battery that way is a waste of time and water. Fire fighting teams that try to put it out like that will see the flames go down, then they let off, and then it starts right up again. In the end, the car burns through the entire battery pack one way or another. You're just delaying the inevitable, and it takes most of the day and swimming pools of water to get done.

Fire crews need new training and equipment. If possible, the car needs to be towed to a safer location. Then you let it burn. There are fire proof blankets that can cover the car to prevent spreading the fire elsewhere. Takes about an hour. Sometimes, a little water helps prevent spreading to other things, but it's minimal.

There's no such thing as "ASAP" for nuclear power. If you had the permits signed off today, it would take 10 years before a single GWh of new nuclear energy goes to the grid.

Instead, maybe we shouldn't build giant spherical advertising displays?

You know, I'm getting really sick of these comments where people think they know what they're talking about and repeat a bunch of talking points about lithium.

Lithium is not going to be the basis of a renewable grid. We need it for EVs because it's the best Wh/kg that we have right now, but we don't care so much about weight for grid storage. Cost/kg is the main measure we care about there (though there are some other considerations in specific conditions). We already have tech being deployed in the field that's better than lithium for grid storage. Flow batteries, flywheels, pumped hydro, or just heating up sand or rocks. Others, like sodium batteries, are being manufactured and will probably find their way into real products in the next few years.

If only Las Vegas were located somewhere that the sun shines almost all day every day. \s

Time to start Rule 34'ing a Blooper with a Bullet Bill on principle.

Nvidia has a >$3T valuation, and that's entirely based on feeding the AI bubble. Without it, they're worth closer to what they were in 2022, which is about a tenth of what they are now.

TLS already has quantum-hardened algorithms in it.
