Who cares about the efficiency when solar panels weigh over 50 kg per kW? Even at SpaceX prices, the cost of launching a solar panel into space is hundreds of times the cost of the…

Did they? It sounds like they had access to confidential Apple documents, which allowed them to rewrite their patent in a way to make it look like Apple infringed on technology the…

Yes, but how are they going to do that if they can't see the drone? How will they know when they have succeeded? Are they just going to continue driving recklessly until they run o…

Following this train of thought to its logical conclusion: Without children's entertainment, kids would be forced to read free books from the library or go play outside. The horror…

Doppler shift due to observer speed will almost always (i.e. for anything other than an actual ballistic missile, and even then only a missile traveling west) be less than the dopp…

Small generators rarely have emissions control systems anywhere near as good as the main engine (and it most cases, far worse). They usually have a completely open-loop fuel mixtur…

Actually, Steve Mann was doing this fifteen years ago. There are web pages describing his wearables that literally haven't been updated for a decade. Think about that for a second.…

No. This is wrong. First, sampling need not imply quantization[1]. Second, the signal to noise ratio of the continuous signal source is important. With sufficiently many bits and s…

>they convinced the labels to stop requiring it. Are you sure it wasn't the other way around? People were building huge libraries of music that only worked on Apple products (iPods…

> Also - does he really have so much experience with that tech? Well, I, for one, was fascinated with wearable computers for a time after reading an article about Steve Mann (in MI…

I too think this is a very exciting sub-field. EMTs and the like already have something like this, only better: It's called a pulse oximeter, and it determines both heart rate and …

> I don't 100% get the band limited signal bit. How does band limiting imply that there's only a single possible reconstruction of the digital signal? I can kind of picture the fou…

The overnight stop is really a red herring: The battery only lost about 5-7% of capacity overnight, which is much less than the difference between a standard charge (90% of capacit…

I speculate that it is a interaction of several things: 1) The current firmware assumes there is "unlimited" energy available when charging, so it can keep the battery warm with li…

You could always rent a vehicle for your remaining driving needs. For 10% of total driving that might be somewhat impractical, but 10% sounds like a pretty high estimate for trips …

I'm not sure why you bring up Classic, Carbon, or PowerPC. Rosetta was dropped from Lion (two releases ago) and support for Classic was dropped when Rosetta was added. MS Office 20…

Actually, I think you misunderstand the analogy. The color of the middle wire on the distributor is something you'd like a prospective mechanic to know, so he isn't learning on you…

Regarding point 2, the article gave me the impression that they used historical measurements of the the mains frequency as part of the analysis. Since Britain is on a single grid, …

Well, you're right: It is 2012, and there are (at the time of writing) all of 6 supercharger stations, which can fill a battery at up to 120 kW. The current incarnation (heh) of th…

I think part of the problem is also that many people underestimate the amount of time it takes to stop for gas. For city driving, you start with a full battery in the morning and n…

It's not so much that they need to be created in one piece [1] as that they need to be annealed after taking shape.

No, they really shouldn't. Autopilots are very good at handling routine, monotonous tasks and very bad at handling unusual or unexpected tasks. See, for example, Air Canada 143, Br…

There isn't really a substitute for Excel if you want to use big spreadsheets (more than, say, a few hundred rows and a few dozen columns). Neither LibreOffice nor MS Office is rea…

They can't add that feature because they already have it.

In a word, "no." There are 3rd-party add-ons available from the App Store, but those only cover a subset of cities. Also, there don't seem to be routing plugins that can find trans…
