- Comment on France runs fusion reactor for record 22 minutes 2 days ago:
Well, there were a lot of fundamental steps that had to be completed first, not least of which was a high pressure vessel. This all took a lot of materials science, advancement in seemingly unrelated fields, etc., etc. Not unlike fusion technology… The difference is we have 2000 years more advancement than they had when they invented the steam engine.
- Comment on France runs fusion reactor for record 22 minutes 2 days ago:
It was about 1800 years between the first steam engine and a practical steam engine. I’m sorry that one or two generations is too long for you.
- Comment on New thermoelectric generator converts vehicle exhaust heat into electricity, boosting fuel efficiency 1 week ago:
Even solids are mostly nothing. This is why neutron stars are so dense - there is a lot less nothing between the neutrons, largely due to gravity.
Here’s another way to think about it. A gas is like a bunch of balls bouncing around a room, hitting the walls and occasionally each other. A solid is like a ball pit, but the balls are vibrating. There is still a lot of bouncing, but most of themstay together.
- Comment on The Cybertruck Appears to Be More Deadly Than the Infamous Ford Pinto, According to a New Analysis 1 week ago:
There are two American rocket projects in the works that can carry a significant payload to the moon. One is using existing parts in a new configuration. It had one successful launch and cost $4B ($2.5B in launch costs alone). One is building a largely new system and improving existing elements and is estimated to have cost less than $2B so far, although it hasn’t reached the moon yet. That said, they have done 7 tests, at least 3 with a full configuration. How is that not better than the other option?
Also, you are acting like there are no fundamental advances happening in space engineering. Sure, the physics is pretty well-known, but the engineering problem of landing and reusing stages/rockets commercially has only been done since the Falcon series, so I think it’s safe to assume the technology and associated product lines is still maturing.
- Comment on LegalEagle Suing PayPal's Honey 1 month ago:
This really does fall under two umbrella cautions. There’s no such thing as a free lunch, and how are they making money? Suspicion was warranted from day one, especially if it was owned by PayPal.
Now, there are a lot of smart people on the internet who could have tracked all those messages and figured it out, like ultimately happened. I just wish they’d done it sooner.

I believe we can make a self-driving car with only optical sensors that performs as well as a human someday. I don’t think today is that day, or that we shouldn’t aim for self-driving to be far better than human drivers.
- Comment on Not allowed to work from home 3 months ago:
Land of the free and all that. Free from paid healthcare, a decent public education, a strong voice in government, an impartial justice system, employee rights… With all this freedom, it’s hard to imagine wanting to be anywhere else.
- Comment on Inside the U.S. Government-Bought Tool That Can Track Phones at Abortion Clinics 3 months ago:
It has been know for at least a decade, I think, that the GSM chip could still contact cell towers while the phone was powered off. I’m sure its successor hasn’t lost that capability.

- Comment on Men Harassed A Woman In A Driverless Waymo, Trapping Her In Traffic 4 months ago:
I’m not sure what your point is. It is completely orthogonal to mine. In the same vein, no, you aren’t responsible for other people’s choices, and yes, rabid dogs (or people who act like them) are unlikely to listen to reason. Neither of those are good reasons to start fights, and that statement neither says that all fights are avoidable or that one mustn’t defend oneself.
- Comment on Men Harassed A Woman In A Driverless Waymo, Trapping Her In Traffic 4 months ago:
Yes, and the vast majority of scenarios where that is the case is where one party made completely unreasonable demands or turned to violence as the first option.
- Comment on Men Harassed A Woman In A Driverless Waymo, Trapping Her In Traffic 4 months ago:
You’re correct, there aren’t always non-violent solutions, but those are often due to people who insist on engaging in violence, whether it be invading another country or taking offense at someone pulling into their driveway.
- Comment on Men Harassed A Woman In A Driverless Waymo, Trapping Her In Traffic 4 months ago:
I once had someone get in my face and say, “Are you man enough to fight me?” I responded with “I’m man enough to find non-violent solutions to my problems.” Why should someone be proud of the problem-resolution method of choice for 3-year-olds?
- Comment on Starlink kit found amid wreckage of Russian drone 4 months ago:
So they would have to have a white-list for Ukraine and a process for getting on the white-list. That doesn’t seem that complicated. Somewhat intensive, sure, but a very simple solution. And I would think militarily advantageous equipment would be more controlled in a war zone than normal.
- Comment on Starlink kit found amid wreckage of Russian drone 4 months ago:
Most people don’t feel loyalty to the country they betray. It isn’t a requirement to be a traitor.
- Comment on Starlink kit found amid wreckage of Russian drone 4 months ago:
Geolocation is very different when you use an omnidirectional antenna passively listening to multiple signals rather than a directional antenna connecting to a satellite for a bidirectional communication session. And all of this ignores the simple fact there are sanctions against some countries and a war going on in another. They are the seller of their antennas and could easily limit who is allowed to change the region of their antenna to work in the white-list zone. Starlink knows the exact equipment I bought from them, and they will know if I move it, and if I change ownership to another person (who actually uses it). Yes, none of this can happen without some administrative or programming work, but that’s the case for many companies if they don’t want to break the law.

The suicide bag uses a similar process as the suicide pod, but is very much DIY. Shouldn’t be too uncomfortable unless you’re claustrophobic.

- Comment on Grid-scale batteries: They’re not just lithium 4 months ago:
Sodium ion batteries are really just hitting the mainstream. Prior to now, they appear to have been more from pilot projects/factories, but a couple large factories are being built now. I expect they will be very popular for stationary use in a couple years.
- Comment on ISPs tell Supreme Court they don’t want to disconnect users accused of piracy 5 months ago:
The people who sell electricity are surprisingly happy to sell you electricity. If you happen to do something horribly wrong and don’t burn your house down, an electrician will be happy to do the repairs. If you have 200 Amp service and draw the full 200 all year long, the most significant reaction would probably be getting a personalized Christmas card.

Tell that to a bronze age engineer, and they will probably respond that those two are closer to each other than they are to his best efforts. And he would probably be right.
