Of course, this way of generating energy will only have a very tiny effect.
In essence, these systems are stealing a bit of energy from the walking crowd.
Let's assume the following: The system relies only on difference in potential energy. Say the engineers were smart and constructed an elevator that converts the potential energy of the passengers into electricity with close to 100% efficiency. For every 70kg passenger this would generate slightly under 2 watt-hours, assuming that the elevator covers a distance of 10 meters and does not take anyone upwards. That's nice, but it's a rather irrelevant quantity in comparison to what it takes to operate the whole system. At the current costs of energy and transport, my exemplary passenger would need to cover a vertical distance of over 50 kilometers(!) to produce an amount of energy that is of equivalent value to the price of one single subway ticket.
The bootup time does not really matter, employees will find other work-related stuff to do during that time.
Having a setup where all the PCs can be booted remotely to update the system will actually save some time, especially when it comes to those annoying Windows updates that want to reboot the computer instantly.
You could also boot all computers around 7.50 in the morning and have them go into suspend mode so that they're ready instantly when the employees arrive in the morning.
You might also want to take into account the amount of energy that is spent on additional airconditioning during the night.
It is rather pointless to argue that there is no use for quantum cryptography because the current methods of distributing keys are strong enough for most users and the weakest link is usually somewhere else.
If some companies, agencies, etc. decide to adopt an expensive quantum physics-based key distribution system, they will probably know quite well why they are putting money into it.
You surely know that some IBM chap once said "There is a world market for about five computers." Fine. Nowadays, there is a world market for about five billion computers, but that's not the point. The point is that back then some companies were not reluctant to develop computers for that small market, and so are the folks who develop quantum key distribution systems today. Who knows, maybe it'll be commonplace technology in a few decades.

You can also take the subway or a cab whenever you like to. Makes sense in a metropolis that is already choking on traffic, doesn't it?

I'm sure most people who bitch at the notion of having their cars tracked while being in NYC will probably carry a cell phone. Thus, they can already be traced with greater accuracy than their cars as these will have their license plates scanned only every now and then.
I disagree. I think the switch between Dvorak keyboards and regular keyboards is hard because they are very similar in shape. Otherwise said, I don't think I got worse in typing on the PC when I improved my typing on my phone. (I do, however, get a little slower on the PC when I switch between keyboard layouts.)
Movies on Cellphones are not that new. Back in 2005 I remember watching an episode of The Black Adder on my Nokia 6230i. The phone even came with software that converted mpeg files to a mobile-friendly format and the picture quality was ok.
NeoOffice and OpenOffice definitely have good word processors that can handle MS Office's documents well, but not all is well when you look at other applications. Last time I tried in vain to sort a table with NeoOffice's spreadsheet app. It just didn't work correctly. Needless to say, I gladly switched back to MS Office.
What I want is a USB Keyboard extension that is maybe twice as large as the number pad and consists of buttons that can be labelled individually. Then I'd like to be able to assign a sequence of key presses/characters to every one of these keys.
I want to be able to press, for example, a key that's labelled instead of typing/mu. I don't need no fancy displays, I just want more keys!
Problems have arrisen between children unable to speak each others language, and a caste system is developing in which the left-screeners or "sinisters" are considered unclean. However, it turns out that the sinisters are also more dexterous.
Go ahead, write a scientific paper on what you found, and send it to a couple of peer-reviewed journals to see if you can get it published. If you think that all the physicists you deal with don't know what they're talking about, you're probably wrong.
Let's discuss the following aspect: Assume that an USB stick was given to me by a stranger as a gift. Let's further assume that the USB stick contained an mp3, but no mention of the artist who created it, no copyright message, no license, and the stranger didn't say anything about it. Would I be allowed to publish the mp3 on the internet?
Similarly, if NIN intentionally lose USB sticks with some songs from their unreleased album, how could the finder be expected to know or verify that the mp3 is actually a real NIN mp3 and copyrighted? Call Trent? At what stage does a song that is sung become a copyrighted song?
Ummm...I don't know why the Canadian system is f***ed up, but in some European countries the system that the OP described works quite well. The healthcare agencies are more or less owned by the government and thus they don't need to be profitable, neither can they go bankrupt easily. That means that they don't have an incentive to deny to pay for some expensive treatment if it is deemed necessary. It also means that hospitals and doctors have their fixed tariffs for standard stuff, so it is hard for them to overcharge.

I guess I'd use it to wirelessly power my flying electric car.
Plus import taxes and duties. Maybe.
That's good for deaf people!
Y is a consonant in German as well.

Are you kidding me, Areyoukiddingme? ;-)
Obviously, the card then is very susceptible to theft.

The minidisc would have been an ideal medium for data transport in a time where people mostly used floppies and -later- 100MB Zip disks.

Thanks, but this is quite probably really really expensive.
Thanks, this is exactly what I was looking for! Now I wish it were a bit less expensive ;-)

If you can build your device and prove that it works, it's quickly gonna be scientifically accepted.
But those devices that aren't scientifically accepted, but still earn their owner a ton of money, are usually the ones that don't work!
Go ahead, write a scientific paper on what you found, and send it to a couple of peer-reviewed journals to see if you can get it published. If you think that all the physicists you deal with don't know what they're talking about, you're probably wrong.

Yes, but a train crash usually doesn't mean that everyone inside dies.
