There has been a few people I've read about proposing a solution to this on Mars. Mars is absolutely chock full of these "lava tubes" caused by old long dormant volcanos. If those could be sealed, they could be used for human

Torvalds has been exceptionally tame by comparison as of late. He's adopted a formal CoC, admitted he is often a real jerk, and is seeking professional counselling. You know, he is acting like an adult in this entire thing.

One of the big breakout moments for Linux was when IBM added SMP support. Before then it was never useful for anything "serious" or commercial generally speaking. Linux was a really nice hobby before then.

Maybe, but SpaceX strongly dislikes doing expendable mode, if at all.

by SEJeff 7y ago
A Falcon 9 has a LEO payload capacity of 22,800kg in expendable mode, something SpaceX does not like to do. The largest payload mass they've carried to LEO was Starlink-2 at approximately 15,600kg (60 satellites at 227 kg each).

Oh of course. Missile submarines carry both however. They're more likely to use the tomahawks however. The Navy loooooves to use them. During the very first 48 hours (sustained) in the war in Afghanistan, a tomahawk missile was launche

Generally speaking, ICBMs are strategic weapons exclusively. The tactical version of ICMBs are just tomahawk cruise missiles, and they're in nuclear submarines all around the world just waiting for the signal.

You're describing the Stryker Combat Vehicle, and it has a remotely operated weapons turret. However, it can only carry 9 infantryman (in addition to its crew). https://en.wikipedia.org/wiki/Stryker

I’d say this is false, even as I myself am a US Army veteran who spent a year in Iraq 2003-2004. Tanks are still useful, but aren’t as useful against non-conventional forces. The pentagon has spent the past 4-5 years retooling for what they

To be fair, they've just massively upgraded the M1s to where they're nothing like the original tanks at all: https://nationalinterest.org/blog/buzz/armys-new-tank-here-c... It isn't as though they&#

You sidestepped my questions. Does your doorbell have one or eight cameras? Even if tesla did it as efficiently as your camera, it would be, at a minimum, eight times more energy. If they do anything fancy with a neural network (which they

And nvidia’s faster neural network solution they say is faster than Tesla’s Chip still uses loads more power than Tesla’s chip does.

Does your doorbell camera have one or eight cameras? The Model 3 has eight cameras. You’re comparing apples to orangutans.

That’s not true. Panasonic disagreed with you in their latest earnings call. They’re ramping up for more production. I think Elon has stated they can ramp up 30-50% with the existing space.

How many other launch providers before SpaceX even had feeds of their launches or their payload separations? People really should stop complaining about the really cool thing SpaceX does, but not perfectly.

For the Tesla Semi and Cybertruck to not be huge loss leaders for Tesla, they have to have made a fundamental breakthrough in battery cost. I'm anxious to see what they come up with.

Maxwell made ultracapacitors not supercapacitors. Elon has stated that those weren't useful at all for Tesla, but their dry battery electrode manufacturing process stands to be the holy grail. This is what I was referring to.

I'm entirely with you on Tesla's market cap defying reality, but the idea that Toyota is going to buy a company with a market cap that is 75% of its own market cap it utterly ridiculous.
715.
by SEJeff 7y ago
As of this very moment, the market caps of both are as follows: Toyota: 228.41 Billion Tesla: 144.2 Billion That's time and a half, but not more than twice. I find it stretching credibility to think Toyota could afford to

That and the most obvious reality that love the guy or hate him, Tesla isn't Tesla without Elon. Unlike SpaceX, Tesla has to Gwynne Shotwell. It is Musk who drives the engineering (and causes an enormous amount of turnover as a result)

Where you're defining better as faster, however, it uses enormously more energy, which impacts overall driving range. It doesn't need to be faster past a certain point. They've already got enough bandwidth to run the entire s

It isn't just production, but is also the chemistry. Tesla has the lowest amount of cobalt and nickel in their batteries of any battery manufacturer in the world. It makes their batteries cheaper, but also use less rare earth minerals
