Same situation for our mid-Atlantic home. There's a ton of pent up demand for this service in all of the rural and semi-rural pockets of the U.S. We have been very poorly served by Congress, state, and local government.

> We have been very poorly served by Congress, state, and local government I live in a semi-rural area. I chose to live there. Why should everyone else pay to give me top-tier internet access? If high-speed internet access is important to me, I need to move to a neighborhood that has that amenity

>I live in a semi-rural area. I chose to live there. Why should everyone else pay to give me top-tier internet access?

One could as why everyone else should have to pay to give you postal service at the same price as someone in, say, NYC when the cost of provision is much higher.

The reason the person above you mentioned government is that it's likely that government owns the streets that any net access would run through as well as having countless other regulations that would need to be followed.

Musk himself has stated the goal is to make money to help pay for colonizing Mars.

"Musk himself has stated the goal is to make money to help pay for colonizing Mars." Which I continue to misunderstand ... You can go to Mars ... you can have an outpost on Mars ... you can have scientists and tourists and so on go back and forth to Mars - all very positive and exciting. But you can't live on Mars for an extended period because the gravity is 1/3 of earths. Your teeth will decay. Your bones will weak…

We only know how the human body reacts in 0g - and it's as bad as you say. But we don't know if 0.3g is bad. Humans might live perfectly fine in 0.3g, or it might be as bad as 0g. However, there's no data either way to make the claims you are making.

This is good news for the USA, but it's GREAT news for countries where the government regularly cuts off and controls the Internet for political purposes. If receivers can be as small as a personal laptop, expect a thriving black market in them in places like Iran and Egypt. Such receivers can also act as backhaul for mesh networks, providing access to un-censored information in times of turmoil and peace alike.

They are transmitters and receivers. It would be like putting a "kill me" beacon on your house if the government opposed it.

So maybe don't use it from your house?

Sad.. Let's hope for breakthroughs on quantum entanglement research then

Quantum entanglement cannot be used for classical communications: https://news.ycombinator.com/item?id=12548175#12548733 "Basic principle is that while measurements between both sides will be correlated, it's not possible to tell how they are correlated until both sides compare measurements." https://physics.stackexchange.com/questions/203831/ftl-commu...

Let's hope for "dig a really big hole through the center of the earth" research then?

:)

> But you can't live on Mars for an extended period because the gravity is 1/3 of earths. Can't you rather cheaply create a centrifuge where you'll sleep - and may be even work indoors - which will maintain 1G? Centrifuge big enough so no significant side forces would occur?

This is my question as well. We do that at fairs for fun, a spinning habitat seems very feasible.

25ms is pretty close to my broadband latency across Australia(Brisbane to Sydney).

1. Neither is rural. 2. LOL at Brisbane to Sydney being "across Australia" :-)

I'm sorry, cross state. I was attempting to point out exactly how shit the current internet speeds were, although I could've been clearer.

Where do you see anything about the antenna size? All I've seen is that this will be for Enterprise customers, and the antenna will be very large. By the way, a very small phased array will be very low gain, thus using more capacity on their satellite for the same speeds. Unless they've invented a new type of antenna...

It's a verbatim quote from the link in my post.

Feasible for a few billion people, eventually? This concept has been explored in many sci-fi shows, with the usual solution being to make a big ring and spin it in space.

> I fail to see how one could actually live on Mars without sacrificing 30 or more years of lifespan. Maybe they just cant can't, but don't care. Some people could be willing to decrease their lifespan in order to colonize a different planet, making the human race interplanetary. Also, theoretically, people will evolve over time to be able to handle those conditions. We're used to making plans a couple years ahead. W…

Evolution happens over many generations, if people who are less fit for survival die before, or are prevented from reproducing. You don't want to go down that road.

The alternative is to stay on a planet where 20-40% of people don't even "believe in" evolution or taking care of the planet which their eventual descendants would need to inhabit, many times in favor of short-term capital gains. I fail to see how we're not already, as of about a hundred years ago, pretty screwed either way.

It's been said before, but what people need to understand is that the goal of this service isn't to make money- it's to balance demand. SpaceX can plan to launch be 30% more launches than their actual customers need. All those extra rockets are used for internet satellites. If there's an accident (boom) or a sudden need for more rockets, the internet satellites get delayed, and the paying customer gets a rocket. If c…

That's not true. Wsj got their revenue projections for 2020+, and the bulk of it was satellite internet revenue. http://www.wsj.com/articles/exclusive-peek-at-spacex-data-sh...

And maybe they will make money. But they aren't making the company just to make a profit from it- they're making it to increase demand for rockets, which they also make.

The smart industrialist expands his business to become his own supplier and his own customer.
