What is "quantum communication"? So far the only quantum communication we've done over distance is via photons, which are still photons.

Well, speaking for myself, I do use different amounts of electricity during the day. As does everyone in my region. And your region, probably.

"current electricity and gas prices"? Those vary. > They only make sense in places that need cooling too, or when electricity gets cheaper. Heat pumps are used way farther north in the US since I was a kid, including (now) in p

Electric heating? Do you mean resistive heating, or heat pumps? It's been difficult in this discussion to figure out what people are saying.

That wasn't theoretical installed base, it was actual power produced.

How is it similar to Sweden, when Sweden is colder?

One good example is electric car charging... all the EV owner has to do is opt in, and an algorithm can do the rest.

Does your number include electric heat pumps? Germany is warm enough for very modern heat pumps to do well.

I had a funny bit in a restaurant recently: we asked the waiter to recommend something, and he shows up with a bottle and a corkscrew and a white towel, ready to do the bottle-opening ceremony. He extolled the virtues of the wine, finishing

Other than those pesky maintenance issues for older plants, and their proven inability to build new ones at a reasonable price?

OK, let me expand it out: F9 is a little smaller than Ariane 5 and FH, everything other than Delta IV Heavy is a little smaller than Ariane 5 and FH. You probably know all of this already. Please, let's stop deconstructing my grammar,

Yes, it's amazing how the numbers pile up over time -- Ariane 5 was a great market fit for a long time until recently, and SpaceX has a crazy high F9 launch cadence.

> It's also made me wonder if there's a way for humanity to pivot to more "horizontally" scaled science. We do a lot of that already. The purpose of flagship observatories is to do what can't be done with many ch

The story from the astronomy side was that the 2.4 meter mirror was mysteriously inexpensive compared to anything else in the R^2 mirror cost curve. It's a little odd how people re-tell that story, but ok.

by wumpus 5y ago
So you're saying that I completely forgot about Falcon Heavy, which I have personally seen launched twice? OK then. It has 3 successful launches, which is fewer than 106.
377.
by wumpus 5y ago
SpaceX F9 has 106 successful launches after their last failure. Ariane 5 has 106 launches since their last full failure. (1 partial failure in there.) Of course, F9 is a little smaller, everything other than Delta IV Heavy is a little small

NROL-30 on Atlas 5 apparently had a shorter lifetime after the "fix", and that is normally considered a "partial failure".

It was a major feature of blekko's search engine. Google had it for a while, too.

That's windows-only, right?

Tesla doesn't have any "drive by wire" cars, the steering has a mechanical linkage.

Sorry, it was at an off-the-record conference. As a result it was a very candid talk!

That's about 1/3 of the story of the battery swap experiment. Tesla put engineering behind making the battery easily removable in all Model S cars, but actual customers (like me) didn't want to use battery swaps. I'd rat

One of the best talks I've heard recently was by an early-20s engineer talking about safety-critical software for trains. Yes, it's very different from most software engineering. No need to snicker, just do the appropriate thing f

I was only talking about JWST looking at Hubble for exactly that reason. Sorry you found my words confusing.

The fixed fairing has been successfully launched twice.

by wumpus 5y ago
Webb is at L2, so if it wants to look at Hubble in low Earth orbit, it's going to be pointing at the sun.

Sure, they're different telescopes with different instruments and different sensitivities.

The aspect ratio rule fails for a bagel-with-cream-cheese from a NY food cart, clearly a sandwich, which has a square of cream cheese which is as large as the bagel in 2 of 3 dimensions. I don't really get how your prescriptive rule me
