Re: Thought about using nuclear?

Nuclear power plants are *scary* to people who are easily whipped up into a frenzy. That is pretty much why we do not have enough of them.

/me operated nuclear reactors for the U.S. Navy, pushing a sub around the world for close to 4 years.

Yes. We need more nuclear power plants, and NO dependency on Vladimir Putin's pipeline.

(if nuclear electricity were charging electric cars, I would consider getting one, but most likely it is coal or oil since they would get charged at night when the rates are lower)

Re: So?

When "they" (the climate ALARMISTS) disprove everything that I've said about CO2 (with science) _AND_ stop private-jetting around the world while SMUGLY telling the REST of US how to live OUR lives, and stop legislating and regulating fuel and electricity prices and availability to the point where we are ALL (except for THEM) living like we are in a third world country...

THEN *MAYBE* I WOULD LISTEN TO THEM.

In the mean time, they should stop venting their hot air into OUR atmosphere, get out of OUR way, and leave US alone from their CLIMATE ALARMIST HYSTERIA!

Re: Speculative execution exploits in the wild?

The other thing to consider is whether or not this is needed at all.

In the cases where "sensitive data" is NOT of a concern, why not disable the mitigation?

In the cases where "sensitive data" IS of a concern, put the mitigation(s) in.

Then disclose to customers which is which. Pricing would be related to what the customer wants.

In MY case, my company web site (shared hosting) has public downloads, customer related downloads (modified linux kernel source in one case) and nothing else that would in any way be a compromise if someone leveraged an exploit. On a shared host this might be an issue but not for me.

So if it is a CHOICE for cloud services, maybe not so bad?

Re: Storage ? Transport ?

have they solved the issues with storing it ?

First thing I thought of. Recent criticisms of NASA around using H2+O2 fuel for Artemis point out that SpaceX uses a hydrocarbon fuel which makes for smaller (and safer?) rockets.

I would LOVE to use fuel cells to power an electric car. Self-contained (does not need "the grid" to charge) and could theoretically be refueled as fast as a gasoline car.

However, no safe+effective storage available for the H2.

THAT much at least might be an advantage.

But the Cali-F-U EOC and other agencies ALREADY collect too much info based on demographics. It is useful for lawsuits (both sides potentially), but it is a *bit* racist and sexist to make ANY kind of distinction by sex or race (or whatever identity floats your boat INCLUDING religion, politiics, and old age).

I do not think it will change much EXCEPT the ADMINISTRATIVE cost of employing people.

Re: Recycling

well space shuttle focused on re-usability and was a bit of an experiment in that regard.

SO yeah SRBs plus "one big tank" instead of multiple stages, and yeah the shuttle engines had to work well in a vacuum as well as on the ground. A compromise. Most of the aerodynamic losses were probably nn the fuel tank, though, before SRB separation. So the SRBs would have (probably) made up for any advantages of using fuel oil at those altitudes.

I think the same logic applies to Artemis, use the SRBs to assist where H2+O2 makes less sense, but get max performance out of the whole system trying to use just one stage + boosters to achieve orbit.

more of a philosophical decision, perhaps?

Re: Go Starship go!

methane is certainly more dense than H2 and can be liquified more easily, but you get the hottest burn with H2+O2. Hotter means better thrust efficiency. This is why engines that only operate in space (for Apollo) use H2+O2 whereas engines that act as 1st stage boosters often use other fuels for reliability and physical size (H2 tanks need to be much larger).

[Engineers doing the math, figuring out what works best]

To double thrust you must do one of two things: double the mass flow rate, or quadruple the energy from the burn. At some point there is a maximum benefit, and I'm pretty sure rocket surgeons (heh) go for that. I would. Then you look at system and operating costs, materials, safety, yotta yotta. It's all figgered out.

Linux

Re: Ah, the equivalent of a modern day rollback!

I started a contract a few years ago working with embedded (RPi-based) systems that all ran Linux. But there was not a single Linux workstation in the place, so I could not get anything significant done using WIn-10-nic even with some of the new,shiny Linux-like command line features (like ssh).

I had installed Linux on an old laptop from 2003 (an old Toshiba) and I did not have another (working) one available so I brought that one in the next day and got BOATLOADS of work done. I instructed a guy with a Mac on how to make an SD card image (he was angry because it took 20 minutes to write an 8gb image from his Mac, but would have taken hours with USB 1.1) and THEN had the thing talking to equipment in short order. There were other problems, like the network firewall NOT letting me update Linux packages and things of that nature (this was eventually resolved) but 2-3 days with that stone-age Linux laptop getting MORE work done than a Win-10-nic machine convinced them. So I took an unused Win-10-nic workstation home with me and used my own (pathetic at the time) connection to install everything (while watching TV (etc.)

Funny how a pathetically slow DSL and an ancient Linux laptop "saved the day" in their OWN way.

(later after severely mocking the network people [contractors] behind their backs for being so anal retentive with the firewall settings, they were eventually "convinced" to set up an IP block that I could use that had NO FILTERING on it. As I needed outgoing ssh to my home network, as well as being able to install Linux packages, this was a MUST.)

Re: Why the bleep dunk these things in salt water?

existing dams and the U.S. Great Lakes are good categories, so long as unfriendly gummints and wacky enviro-activists don't drag the process out to infinity with continuous lawsuits, protests, cancel culture, etc..

If things get to THAT point, sea water (vs fresh) is less of a problem. It would be a matter of doing anything at ALL. And that goes DOUBLE for anything attempted in Cali-F-U . (these are very realistic concerns; years of permitting, protests, legal challenges, etc. can easily kill ANY new construction -project by draining its funds before a single concrete slab gets poured or brick gets laid)

Worth pointing out, barnacles are found close to the surface where the plankton is. So down where it is dark (below about 75 meters), it would be less of a problem. In fact, MOST of the sea growth that can clog up cooling systems is generally found close to the surface.

Also worth pointing out, water pressure increases about 1psi per 2 feet. I do not know what that is in metric, as I observed it while I was on a sub in the U.S. Navy where everything was still in feet and psi (etc.). But the deeper you go the stronger the vessel needs to be. You COULD pressurize it with air, but you do not want the equivalent of a diesel engine at depth going off when pressure meets anything with hydrocarbons and electricity, so it would have to be something inert (like Nitrogen gas). That adds more expense. It makes shallower water look a lot better.

Re: It was just a corporate error

I had the reverse happen to me on a payroll once (typically in the US if you own a corp you still need to put yourself on payroll and pay some kind of reasonable salary). So I FAX the latest rates from Cali-F-U to the payroll company near the end of the year, and a month or 2 later, do the first payroll of the year. Then I read the fine print while entering the bank info and what should have been around $70 "contribution" for this one Cali-F-U payroll tax, was more like $7000 !! (I think they entered the tax amount as 150% instead of 1.5%) Well I couldn't screw around with that one and immediately got back to them. Thing is they probably sent it to a NON-REFUNDABLE fund or something, and took over a week to refund me. (fortunately I had enough in the bank to cover paying myself or rent probably would have been late)

In any case it was resolved, but you know most people will NOT be too quick to say "weren't you supposed to deduct XX" or "Why is this check so big?" if they overpay (or undercharge) YOU.

Re: 70's Tec

I have an old Fender reverb unit (solid state) that was made in the 70's. A few years ago I took it completely apart, cleaned it out really well with contact cleaner [the dust inside stank like cigarettes, bad enough to give me a headache], and re-soldered the solder joints on the circuit board and cleaned up the 1/4" audio jacks and whatnot. Worked a LOT better (had proper gain again) and no more scratchy noise.

The traces on the circuit board looked like they were done by hand using a French Curve. And the parts have a LOT of space between them, not like a pocket radio from the same time period where parts are all crammed together.

Startup wants to build a space station that refuels satellites by 2025

Re: and you thought fuel prices down here were bad!

cost per kg of fuel to deliver it from Earth to the orbiting fuel station, plus fuel delivery bots that ALSO consume fuel, cost of earth-bound operators and all of the infrastructure, and THEN you have to make a profit to pay back the investors. That kinda justifies it.

Plus when you are the ONLY fuel station for 36,000 km you can charge "whatever the market will bear"

(I suppose getting a "tow" might be an interesting add-on service - to put a satellite back into orbit if it runs out of fuel and cannot do station keeping for some reason).

Still cheaper than a NEW satellite.

I still FAX things on occasion. Cali-F-You gummint sends me an updated payroll tax rate (a certain one changes every year), and I turn around and FAX it to the payroll service.

And there is a FAX number in Sacramento that can be used to GRIPE ABOUT GUMMINT when need arises (I did this more than once a week during 2020 for obvious reasons, in large hulkbuster font, often with a photo of a guy fawkes mask).

But the last few years I've done taxes they are always e-filed, and I think corporate taxes HAVE to be e-filed now. Considering the price of paper, copying (or printer ink), and postage, it's about the same to cough up $20 or so to do it vs the old school way.

As for other things, DMV, paying use tax, etc. (even court documents in the state of Maine), it's nearly always an online form of some kind (or even e-mail, depending). So really not THAT bad.

Re: If it steers boots on the ground to double check

to avoid tax "sticker shock", particularly for those who could LEAST afford it, one great thing that cali-forn-you ACTUALLY did, before it fell off the cliff politically, was called "Proposition 13", back in the mid 70's. Housing prices were skyrocketing (you could turn a 10% profit by buying a house and paying only interest like it was rent, and then selling it after a year). Since gummints LOVED to re-assess the houses that were already paid for, the massive increases in taxation were literally driving grandparents and retirees out of their "bought and paid for" homes. SO, the law was RIGHTFULLY changed, in that once you buy a house, the assessed value can NEVER exceed the purchase price, for tax purposes anyway. That means that when you buy it, the tax is essentially the same until you sell it.

(It was one of the few moments of sanity that came out of Sacramento, nearly 50 years ago - and many of my high school teachers were REALLY MAD about it, because they LOVED their money-pile budgets, and they had to start LIVING WITHING THEM like EVERYONE ELSE!)

Re: $2/kwh is a lot of money

Here in Cali-Forn-You expect to pay $.50 / kwh during peak hours. Or more, depending...

I shall not get into why, but when we had more nuclear and oil and natural gas plants, it was WAY less than HALF this much. But that was 18 years ago when Ahnold was Governor. Ahnold became governor due to a recall election of "Gray out" Gray Davis, whose policies had kept power plants from being constructed (as I recall). Ahnold reversed these policies and encouraged power plant renovation (etc.) such as the Moss Landing power plant (an oil burner), and new construction also (as I recall). THEN Cali-forn-you had PLENTY of electrictiy. And it was WAY cheaper, adjusted to inflation even. (I should know, I was here)

Cali-Forn-You STILL has some of the most expensive electricity, though. Even back then. Home solar systems with battery systems (like Tesla's power wall) in some ways help distribute the cost around a bit among individuals, but aren't a 100% solution. It is often VERY hot after the sun goes down (in August), and peak hours are from 4PM to 9PM (when electricity costs the most). Batteries only store so much.

Paying individuals $2/kwh for "peak power" is not unreasonable, actually, when the costis already so high, since it is an average of power generated by many sources, and that extra small percentage for brief periods of time will likely prevent the grid from collapsing. It becomes a drop in the bucket for electrical providers, and a cash boon for those willing to put their surplus power on the grid during the peaks.

It really does NOT have to be this way. We have the technology. But I think *SOMEONE* or *SOMETHING* doesn't WANT us to live like we;re in a 1st world country... so here we are,.

Re: Good job....

I concur with your science. Seems like a good estimate.

1 mole O2 (roughly 32g) is 22.4l at STP, or about 100 moles per day by your calculations (about 3.2kg by this ballpark calculation).

I was actually thinking that if we could "lasso" a comet (or a big chunk of one) we'd have enough water ice to do quite a bit of O2 and liquid water, as well as HC compounds of various kinds.

Worthy of mention, there is a lot of perchlorate in the soil, which also contains oxygen, as does the oxidized iron that makes the soil reddish. You would probably, need some kind of water chemistry to release it, though if you could extract the perchlorates and make them into oxygen candles, then THAT would work nicely! Washing the soil to enable plants to grow is necessary. Using them for O2 and chloride chemicals may just be a plus side to an otherwise water-intensive process.

Still prior to 2020 all of those parts had good inventories at distributors and reasonable lead times,. After China started their sudden and massive lockdowns, it was like a crap shoot as to which components would run out any time soon. these boards are built in USA and Mexico so it would be a GREAT advantage to have fabs in N. America at least.
