Now I want to buy an island and build a new kind of community.
I wonder how much it would cost to purchase an island with 10-20 people and build houses on it. Could you live there in a sustainable way? Possibly seems like an interesting way to live.

Can you even read?
The answer is in the article, sure (OP: much lower altitude satellites, so much lower RTTs), but that was an incredibly rude way to say so. Please don't do that.
I understand that I easily get annoyed, but it is the first topic of the article.
I mean.. why even bother to comment if you don't even read the first few paragraphs?

They've been working on this concept for several years at their Washington state offices. It's just now that we're seeing hard details.

#416napkin math (chemistry style): (4425 satellites * 23Gbps) / ((60,000PB of fixed internet traffic / 1 month [1]) * (12 months / 365 days) * (1 day / 24 hours ) * (1 hour / 60 minutes) * (1 minute / 60 seconds) * (8 bits / 1 byte) * (1024 Tera / 1 Peta) * (1024 Tera / 1 Giga)) = An astounding O(54% of global internet traffic) [2]! Obviously there are many many more variables in this [3]. Nonetheless this will be super…
More numbers to crunch: - Satellite with LEO orbit covers 1-2 percent of earth surface with 10 degree elevation. - Land occupies less than 30% of earth's surface area. Urban areas occupy less than 3 percent of the Earth's land surface. That's where the customers are. You have to divide at least by 100.
I'm not 100% sure I'm following your comment, but with LEO, you don't get to choose a location above earth for each satellite, as you would with GSO.

You can buy a small (~2 ha) undeveloped island for as low as 100,000 USD. Bigger ones cost more depending where they are located. However I saw really big islands (~2,200 ha) for about 2M USD in Chile (I think that is cheap considering that a luxury apartment in my city, Florianópolis, can cost way more than that). Current solar energy solutions and biogas production from waste can form a solid base for a sustainable community.

Correct. That's why I said the way to lose heat in a satellite is by radiation.
Ever heard of the Stefan-Boltzmann Law? This dictates the maximum amount of energy that can be radiated from an object per unit area for a specific temperature. The power is proportional to the fourth power of the temperature. http://hyperphysics.phy-astr.gsu.edu/hbase/thermo/stefan.htm... So for example if you have 300W worth of TDP, and a perfect black body radiator of half a square metre, then the radiator tempera…
Sure, I have studied these things a couple of decades ago. Now that I read my comment above I realize it was badly worded. I didn't mean to say all heat would simply be radiated without posing a problem. I meant that the only way for a body to lose energy in space is by radiation (without ejecting matter, I suppose).

Not sure why you're downvoted. Very true statement, imo.

I suspect this is just a phase. I don't have any hard stats at the moment to back it up, so it's just a feeling. Internet culture is still very young. At least in the US based on the election last week, the majority of people 18-25 voted progressive in most states. These are people who have never known the world without internet access. I guess that the people who voted the other way are folks who have transitioned i…
Nah, those 18-25 year olds are ignorant idiots too. And when they get older they'll start voting conservative just like their parents generation. One anecdote about how ignorant they are... on three separate occasions I had a conversation with a Hillary supporter about her having destroyed subpoenaed evidence. Each of those three cited a factcheck.org article that stated in its third paragraph that she had in fact de…
>How many of them knew Hillary literally created the Syrian refugee crisis in a failed attempt at a coup? Not a single one I talked to.
There is no evidence that Clinton backed or supported a coup in Syria. The US did support elements of a popular uprising in Syria during the Arab spring, and then provided and continues to provide military support to Anti-Assad factions after Assad viciously cracked down on the uprising. A coup d'etat is a very different beast.
The refugee crisis is a result of Assad and Anti-Assad factions acting to change the demographics of Syria via ethnic cleansing. It is unclear, but seems unlikely to me, that the refugee crisis would be lower if the Anti-Assad factions had gotten less support from the US. The refugee crisis would have just happened over a shorter period of time. To avoid increased US involvement Assad regulated his behavior somewhat (see Chemical Weapons controversy). It seems likely to me that the US by providing limited support to Anti-Assad factions acted to limit/control military support given by gulf nations to the more extreme Anti-Assad elements. Such support would likely have made the more radical elements of the civil war much more powerful and likely increased the flow of refugees.
US involvement in the Syrian Civil War did in certain circumstances limit the refugee crisis and has allowed refugees to return home. For example the US/YPG defense of Sinjar Mountain in N. Iraq allowed refugees to escape genocide, then with the recapture of Sinjar, allowed refugees to return home. Another example would be halting of the Islamic State's campaign in N. Syria, which if continued would have generated hundreds of thousands of refugees. Not only was the Islamic State's advance halted, but it has been rolled back significantly with large numbers of refugees returning home. This would not have been possible without US support to the factions (YPG/SDF) fighting the Islamic State.
We can debate the exact nature of US responsibility for the refugee crisis, but (1). any direct responsibility for foreign policy at this level is with the President not the Secretary of State, (2). there was no coup d'etat attempted or otherwise in Syria.
