Comment Re:Corroborating Hieroglyphics? (Score 2) 202

It is estimated the Great Pyramid was built in just over twenty years. So say 7500 days - which means placing 320 blocks a day assuming you work 365 days 24 hours a day. Pretty sure the Egyptians would be limited to daylight hours work, so they'd need to cut & move at least 500 blocks a day.

What? No! The limitation to daylight hours meant they had to be faster per stone,
but it didn't suddenly double the amount of stones needed.

A 2.4 million stone pyramid built in 20 years is built at an average rate of 229 stones
per day, completely independent of the length of the work day.

Actually for reading books knowing where you are does help line up the story. (beginning middle or end)

I think that's true. If so, maybe a small progress bar along the top of an e-reader continuously showing where you are in the book could be helpful. I don't know if any e-readers offer such a feature.

Mine does: "Cool Reader" for Android.

It includes tic marks for chapters, a "% completed" number, and even
calculates "time left in chapter" and "time left in book", automatically
calibrated to my reading speed.

It's very unobtrusive and I rarely if ever look at the numbers, but the small,
few-pixel-high progress bar is quite useful.

That's 28,000 birds for this current, small, solar installation: 0.4GWh, when the US uses tends of thousands of GWh.

Please don't mix units or make up numbers. A GWh is different from a GW.

This installation has a peak capacity of about 400MW. Total installed peak capacity
in the US (Total net summer capacity) is just a bit over 1000GW.

Interesting note: the growth in capacity over the years shown in this graph is made up nearly
exclusively by renewables and gas, both contributing about half. I hate stacked bar graphs for
obscuring such things, but there's a "download data" option in the top right corner of the graph
so you can look at the raw numbers (they're also in the page source, as a JSON object).

When your country becomes the largest military force on Earth, then YOU can dictate measurement units.

Until then, neener, neener!

Ah crap, not another military failure.

Good job on Liberia and Myanmar though, keep it up!

its very telling that the NFL needs a *law* to force people to go to games and pay their exhorbitant ticket costs.

It's the law forcing a limiting of the Blackout Rule on the NFL, not
the NFL being forced to use the Blackout Rule by the law.

The NFL doen't even care about people coming to the stadiums:
The teams are allowed to purchase remaining seats to "unlock"
the broadcasting for the price of the league's share of the ticket sales.

So it's the NFL trying to force maximum revenue per game (for the NFL, that is).

I don't understand how the rule that prevents airing the matches keeps them on free air channels?

Because the NFL has been forced to allow at least that.

I mean, if NFL wants, they sure as fuck can put on a rule that causes them to be always available for broadcasting? and the other way too for that matter.

Yup, absolutely. That's why Blackout Rule is an NFL rule.

I mean, the "if tickets not sold then no show" as a rule sure sounds like it only makes it harder for them to show the matches if they want.

furthermore, WHAT THE FUCKING KIND OF RULE IS THAT!?!? shouldn't the organizer of the event -any event- get to choose if it can be broadcast or not, since aren't they in control of the copyright of the recording????

They are. And again, it's an NFL rule preventing the broadcasting.
In fact, the NFL had to be forced by law (Public Law 93-107) to at least allow broadcasting
in those instances where a game is sold out 72h in advance.

I do understand your confusion though, the summary does a horrible job at explaining what's going on.

My guess is cost. Sending data via satellite is very expensive, and there's a lot of data recorded. As for ground stations, I'm not aware of any plane-to-ground data communications currently in use (other than radio for voice) so that would need a completely new infrastructure built.

ACARS. Already built.
It's rather low-bandwidth though.

trying for a soft touch down with enough rocket fuel ant oxidiser to do a soft touch down is always potentially exciting.

I knew Spacex has done some new and inventive things in propulsion systems.
But oxidising rocket fuel ants? That's just plain weird...
I guess the new facility in Texas will include their own ant farm to keep down cost.

Just simple geometry:

Imagine a planet completely covered with water. Now throw in a big stone at one of the poles:
This results in a circular wave expanding from the pole, parallel to the latitudes.
As soon as it crosses the equator, it starts converging again, until it arrives as a peak at the
opposite pole.

Distance from pole to equator: circumference/4.

This works with a stone drop at any other point on the globe as well, I just used poles and
equator because it's easier to imagine. In reality, land masses complicate things a bit of course.

So, yeah...in short: Germany's done a great job leading the way. But their power grid is 1/20th the size of ours in terms of power generation/usage, and their nation is also a fraction of ours in size. So what they did can't just be copied and pasted into the US to get us to the same proportion of renewable generation.

There is no German power grid: A huge part of Europe is part of a single, phase-synchronous
grid larger than any of the ones in the US. Germany is part of that grid.

Yes, storage of electricity from uncontrolled sources to always be able to match supply to demand on a
large scale is still pretty much an unsolved problem. It's being worked on.

But I'm sick of the "of course it works for them, but it can never work for us, because we're oh so totally
different!" argument. That's just not true, and you have no point.

If anything, the vast amount of empty space makes large-scale facilities of any kind easier. I'm not sure
large-scale anything is the solution though, distributed generation and storage seem the sensible thing to do.
And doing it is just a question of (political) will.
