Let's say you wanted to run 5VDC throughout your house from a single centralized power supply. (And who among us hasn't thought about exactly this idea?) 14 AWG wire, like the stuff you probably have carrying your 120VAC 15A service today, has a resistance of 0.25 ohms on a 100 foot run. That's 50 feet out and back, which we'll call typical for a small house average run. At 5VDC that's a voltage drop of 2.5% to a barely usable 4.9VDC.
That depends on your current. Assuming you have a 200 watt device on 120V, you are drawing 1.7A, with a voltage loss of I*R=1.7*0.25=0.4V. Not a major problem. The same 200 watts from a 5V line would draw 40 A (not remotely safe with normal 14 AWG wire, it is only rated for 5.9A). The voltage loss over those 0.25 Ohms would be 10 V (this is not impossible. We are calculating with the voltage supplied to the device, you'd need 15 V at the "source end" of the cable. You can't draw 40A over a 0.25 Ohms resistance at 5 V, so even a short circuit wouldn't let that sort of current flow).
Disclaimer: I am an electrical engineer, although I am by no means immune to very stupid mistakes.
By the way: do you really use only 14 AWG (= about 1,6 mm diameter) for houses? What kind of circuit breakers do you use? We, in NL, usually use 2,5 mm wires (between AWG 11 and 10) with a 16A circuit breaker, so a short will always trip the breaker before it starts a fire. We do not have fuses or switches in our outlets.
+ 0.5 watt for a complete house is insignificant. A TV in standby often consumes more. If this makes 1% more people switch to CFL bulbs faster (it's NXP, they don't like incandescents) the overall efficiency will increase.
That will only work if the signals to each antenna are in phase. The phase in sunlight shifts all over the place so you can't build a phased array. You do need a rectifier for each antenna. Normal phased arrays are used in conjunction with a single transmitter, which sends it's signal in one phase. The sun isn't one transmitter, it's as many transmitters as there are atoms on the visible surface, each with it's own phase...
I do not think the 90+ efficiency is the greatest game changer. Since they claim it could be produced like a CD/DVD/BR the possibility to create very large surfaces with low costs is far more important IMHO. We have surface area enough, PV is just very expensive per watt. Of course, assuming the cost per m^2 stays the same, increasing the efficiency will help decreasing the cost per watt. The micro-antenna part seems feasible, but I do not know enough of quantum mechanics to asses the feasibility of the tunneling diodes. I have heard of them before, are they in (experimental) production? Do they reach these frequencies? Are they cheap enough to use one per antenna? Is it possible to create these in the same cheap way (with the CD/DVD/BR technology)?
I bet there are window managers that micromanage windows it for you or let you have a different workspace on each screen. Windows is rubbish with multiple screens, always puts things on the wrong screen.
Back during my studies I had a 3 monitor setup with 2 different Nvidea cards on Windows XP. I am not a programmer, nor would I consider myself intelligent enough to become one. Due to a hotkey from the Nvidea tools I found it worked perfectly. With ctrl + ~ I could "throw" windows (even full screen ones) to the next monitor (cyclical: they jumped to the monitor to the right of the one it was on, after the most right one it would go to the left one). Photoshop needs 2 monitors minimum, or you'll cover your work with taskbars (wich you can place on the smaller monitor and windows will keep em there, even if you restart photoshop). On BSD and Suse I missed the hotkey for this switching btw.
While hemoglobin isn't ferromagnetic (able to keep a magnetic field and thus become a magnet itself) it is paramagnetic (it is attracted to a magnetic field). That is the property that Magneto used. Oh yeah, there is also diamanetism but that's just weird (although very common).
Or, it's simply the case a muscle has troubles creating that motion. Evolution is not a route to the perfect solution, but a route to a good enough solution. Of course the arterial system may have some deficiencies that is prevented by the pulsating effect (like clotting).
(Yes, I know I should have walked away from that motherf*cking liar.)
I am not sure whether he's a liar. He may have gotten his HDMI training from his high class expensive HDMI supplier and I have a hunch which cables they want him to sell. He may only be ignorant.
The advertisers will claim the users will skip the ads. The advertisers will not believe the guestimate of the amount of users that have watched it (on TV there have always been samples, now with the digital systems the data is simply available). In both cases they will not want to pay as much.
Hmmm? You know... You know what I've noticed? Nobody panics when things go "according to plan." Even if the plan is horrifying! If, tomorrow, I tell the press that, like, a gang banger will get shot, or a truckload of soldiers will be blown up, nobody panics, because it's all "part of the plan.""
It doesn't fit exactly, but good enough. Coal's slow deaths, one by one, are a side effect of the plan. One death isn't really newsworthy. Thousands of deaths, one by one, aren't really newsworthy. A nuclear plant's deaths somehow tap into an irrational fear. Like a person that dies of radiation is more dead than one who dies of a coal related accident. Like a person that dies of radiation from a nuclear plant is "more dead" than one that dies of radiation from fly ash of a coal plant. It isn't part of the plan.
Most users I know can not be trusted with managing their own system. Common users switch of UAC, clearing the path for virusses. Common users use outdated licenses of useless AV packages (so they will not get updates) clearing the path for virusses. Common users feel backups are a waste of time or forget about them. Common users install stuff to watch pr0n or puppies. Common users click links in mails from friends, even if it's clear the mail wasn't actually send by said friends. Common users don't know shit about how to use a computer responsibly. For them a Chromebook could be a good solution. I am not a common user (although I am not above doing stupid things). I want to be able to configure my system to MY preferences, not some default that makes me cringe in some corners of usage. As with everything: there is no such thing as a single perfect solution.
For products which are funded by advertising, like TV shows, this makes even more sense. The networks are already giving away TV shows for free over the airwaves; releasing them on BitTorrent is just more efficient.
I don't understand: if the product is funded by advertising, how are the networks going to get paid if they release it on BitTorrent?
What is interesting, is how they incrimentated themselves. First, the article states that Nevada would be the first state to allow that kind of driving. Secondly, they openly admitted to doing over 1000 miles of that kind illegally in the state of California.
From TFA:
In the testing program, each vehicle is overseen by a driver and a second Google employee who monitors the equipment from the passenger seat. Because of the human oversight, the company has avoided legal action against reckless — or, in this case, driverless — driving.
From TFS: "Does this further erode the argument that Fukushima was just an isolated incident in the 'modern' nuclear power age?" The plant was build in 1974
These are old reactors and due to "environmentalist" blocking of building new (safe) ones they are kept functioning. Is it strange they start to rot?
Sometimes you simply have to bend your principles a bit to have them. If they didn't protect the identity of their leaks they would not get any new leaks and they would not be able to expose true corruption. The details should have been better written. Now it includes Assange's potential "5 star hotel bills and the scores of hookers on Wikileak's costs" (because leaking it would constitute "loss of reputation") . It shouldn't. It should only protect the information that could identify the leakers.
The large drainage holes can have some sort of floating cutoffs. They usually drop down to seal the hole (more or less) but float on water to let it drain out.
True, at least I hope so. But you have to load and unload some day. In these cases it is customary to enter a harbor. Theoretically you could remove said gun and transfer it to a US Navy ship, but I have to wonder about the practicality of that.
A GAU-8A Avenger could probably be mounted on a commercial vessel and used very efficiently to give the pirates some rather large holes (splatter bonus!)
The problem is: the ships would not be allowed in most marines. I am quite certain you can't simply float a ship with a large mounted gun in the harbor of Rotterdam for example, and I do not think most other countries would be welcoming you.

Even with our big mistakes and the disasters we've seen, it just can't compete with the "working as intended" performance of coal:
