Comment Re:Data centers on the moon (Score 1) 130

And when it's estimated that to launch 1kg to Low Earth Orbit (LEO), you need a minimum of about 30 Megajoules. And something like additional 800MJ to get it to the Moon, it kind of adds up. The estimates are somewhere above 1million $ per kilogram delivered to the Moon.

You're assuming that the availability and cost of energy within a system are fixed.

The amount of energy required to move something to orbit and to the Moon is indeed fixed, that's basic physics. And baring a new and revolutionary method of doing that, the cost estimates will not change significantly and the conclusion remains. Whether it's 1.2 or 1 million per kilo does not really change anything.

Yeah, but those are problems that could actually be solved.

Not without fundamentally new solutions to the problems and new understanding of the physics involved.

Todays data-centers are huge and require huge amounts of power. Simply distributing that power require lots of big heavy hardware. And putting things in orbit and beyond is insanely expensive. Perhaps quantum computing may give some mitigation to the power and weight requirements, but the cost will still be to high. For the transport part, there are noting currently theorized about that may solve it as far as I can tell. Perhaps space elevators, if those are possible. Then again, they only get you to orbit.

Are your calculations for AC?

No, primary based on DC 800V systems just started to roll out and systems in development staring to be installed next year.

As I've just heard of popular developments of DC local zones gaining momentum to simplify all the power management and save on energy losses due to conversion

DC have been in use for a while, the development are more about moving to higher voltages like from 400VDC to 800VDC. Same as seen in the EV segment. Not converter power loss tho, but transportation loss and need for less copper to transport the energy(cheaper). Reducing copper will reduce weight, but it will still remain significant in this case.

Howerer the Earth's orbit is a better place IMO - having constant Sun exposure for power and easier maintenance, so I wonder why the Moon then.

It's not quite right to call it a better place, it's more like a slightly better than incredibly bad place:-)

The potential opportunities include establishing space data centers and infrastructure on the moon,...

Unless you've got quantum networks up and running that's not going to fly for realtime applications: there's an (average) 1.253 second communication delay between the earth and moon... each way!

Yes, but that's really not the big problem at all. It would obviously exclude some applications requiring low latency, but it's a insignificant issue as a whole.

With the naive approach, a data-center is simply lot of computers. Rows after rows racks filled with computers. And when you look closer, those computers require power and power distribution. And those also fills up racks, and in a large data-centers it's thousands of those power racks. A power converter/distribution rack with decent power density easily clocks in at 2000kg or more. And when it's estimated that to launch 1kg to Low Earth Orbit (LEO), you need a minimum of about 30 Megajoules. And something like additional 800MJ to get it to the Moon, it kind of adds up. The estimates are somewhere above 1million $ per kilogram delivered to the Moon. So 2000million$ for one power distribution rack, and you probably need at least a thousand for a small/medium size data-center. It quite fast becomes obvious that data-centers on the moon is nonsense. And the same conclusion are also apparent for data centers in space/orbit. Not something to take seriously, either just nonsense or some kind of scam.

In reality, next to nothing. Since the trains run anyway, they only got more passengers. The cost of running trains is largely static, the number of passengers have very little influence on the total cost. They may have had to increase capacity on a few routes, so some extra cost may have occured. Probably not much.

Germany was the first company to pull the vaccine. They did so in spite of the data.

Since this is not true, the rest of your comment is nonsensical speculating based on false data.

The first contry to temporarily stop using the AstraZenaca vaccine was Denmark, then Norway and Iceland. On sunday Netherlands and Ireland decided the same. Followed later by Spain, Italy, France and Germany on monday.

One of the major things Apple changed when they entered the US smart phone market...

Uh, didn't they CREATE the smart phone market? I mean, sure, there were some lame blackberries and Palm Pilots with cellular links, but wasn't the iPhone what really made the smartphone market?

No definitely not! There was lots of smart phone devices running Windows CE/Pocket PC and a larger shitload of devices running Symbian (Samsung, Motorola, Sony Ericsson and Nokia). Speed and the high cost of the cellular networks at the time was the major limiting factors for their usefulness, along with some limits in the capabilities of the phone hardware. But the market was there, and would have exploded much in the same way when network and hardware evolved, even without Apple. Remember the first iPhone was just a lame iPod with cellular links, without the option to install apps.

With chip+pin all liability falls onto the cardholder, regardless of whether the chip was used or not, and whether a pin was entered or not, and the burden is on the cardholder to prove that they didn't do the fraudulent transaction.

Most of the world (Europe, Australia, Asia, ME and Africa) the consumers are apparently happy with being liable by default. For some reason consumers in the US don't want to allow the merchant+banks+issuers to shift the liability to the consumer.

I'd say that is not correct, chip+pin has not changed the liability. But, being a European we perhaps have more sane laws. Or slightly less scumbag banks.

For a while almost all have changed to chip+pin, but prior it was mag-stripe+pin. This is still available as backup, since nearly all terminals have both. Does not change anything with regards to liability tho.

In any case, most places here now also support RFID tapping. With pin mandatory for purchases over something like $20, in addition to every X purchase(4 or 5 I think).

And there you already failed, and mixed the terms up.

Master is the one doing the query/ordering and Slave is the one to answer/respond. Exactly the opposite of what your alternative does. The Client is the one query/ordering and Host is the one to answer/respond.

It's rather quite simple, but you have several contributing factors other than electric cars being quite nice.

- Tesla tend to deliver in batches to different markets, so they get some real good months in the statistics.

- Added benefit for electric cars, like free parking in some areas(e.g privately regulated parking). And being alowed to drive in bus lanes(With heavy comuting from wealthy areas, you get many who can afford a Tesla to get an edge in the morning trafic).

- No general road tax and free pasing of toll roads.Norway have lots of those.

- No tax when buying one. Basicly you get it nerly at halve price compared to a gas car.

What country have you worked in where workers are more empowered to make decisions, and trusted to act independently?

Obviusly you have newer worked in scandinavia. From experience it seems the Americans tend to go for more bureaucracy and shuffle all requred descissions up in the system. And you often get the impression it's more important to cover your own ass, than get things done.
