I get a number closer to 300 million hours. I think Randal's adding machine slipped a cog.
No, he just wrote "hours" when the correct unit is "person-decade".

Painting the mountain pink... that was a nice touch. Nobody was expecting to see that, which I guess was the whole point.

I have it on good authority that, if it is a normal torch battery, the field should remain powered for over a century. It should still have quite a bit of time left.

Scrap metal? I thought it was about German soldiers who wanted to flee to Germany, as the Americans and Canadians were on their way, and they didn't have transportation back home.

Whatever the case, I love that Randall is making Dutch-German jokes.

"currently off"

When Hitler thought about destroying Berlin and building Germaina (City) instead, he ordered the en.wikipedia.org/wiki/Schwerbelastungskörper to be built. Turns out Berlin's ground is too soft.

That was O'Neil, with one L. O'Neill with two Ls is a different guy with a much better sense of humor.

There were so many differences between the movie and the series that we can't be sure how the original spells his name.

But at least they didn't use time-travelling to justify the changes. And they gave up on the gratuitous nudity as soon as their contract permitted.

Yes, we can, because it is spelled in the movie, in the script, subtitles, or credits even if not spoken or shown by the actors themselves.

Also in the show, O'Neill tells a reporter once how to spell his name, and clarifies that there's a different Col. O'Neil in the USAF, one who has no sense of humor.

Oh, yeah, we clearly know the spelling on the show because they call attention to it (though again even if they didn't the credits would have the canonical spelling).

Hm, I confess I was thinking of the other form of pyramid energy when reading the title of the article. If all the energy people spent promoting (and chasing) Ponzi schemes was spent building rockets... where would we go? Stats?

Also, although I'm not certain of this (as I never made an effort to pay close attention to this in particular when watching the show), I would assume it is visible on his uniform in (nearly?) every episode. Possibly the credits as well.

"What took more energy, the building of the Great Pyramid of Giza or the Apollo Mission? If we could convert the energy to build the Great Pyramid, would it be enough to send a rocket to the Moon and back?"

Ah, but the question asked about sending "a rocket" to the moon, not necessarily Apollo. Quick, is there a rocket the pyramid could send?




This is a bit late, but... let's take just the gravitational potential energy stored in the pyramid - with mass 5.9 million tons and center of mass 36.5 m above ground, it is 215 x 10^10 Joules (I have no clue how much energy was lost during construction, I think it must have been many times more).

An object in Lunar orbit is approximately 384 000 km high and moves at about 1 km/s. Free-fall speed from this height is very close to Earth's escape velocity of 11.2 km/s - at this speed, an object would have mass/2 * 11 200^2 (m/2*v^2) joules of energy. Same equation applies to energy of its orbital motion (1 km/s).

Now it is trivial to find mass of orbiter that would have energy equal to that calculated for the great pyramid. It works out to 32 820 kg. Assuming no losses in transformation of pyramid's gravitational potential energy to energy of the orbiter.

The plan is completely moronic by any standards, the question about what it would do to the Dutch surface is the least of my concerns. What happens to the Dutch climate if you suddenly put a mountain of 2 to 3km in here. Looks like I've got another question to submit. Especially considering Randall's highly accurate doomsday thinking, I hope that the ridiculous mountain builders forever give up.

Also, it's impossible to get the resources for a 2 to 3km mountain, but still. I want such stupid plans to be shot down before someone even talks about it.

What. The. Heck. :shock:
