To avoid the 20% to 40% power loss when converting from DC to AC

...they're doing it wrong. DC to AC conversion is easily achieved in the high 90% range. For instance, a typical solar inverter is around 95% efficient. And you can do better, it just gets more expensive (although that's a one-time cost, whereas energy loss is a constant concern.)

Someone is pushing some other agenda here.

Sure. Did it to myself decades ago. Offspring of my genetic line aren't of the least bit of interest to me; perfectly happy raising kids of other birth who needed parents (5 so far, mostly excellent results.) Plus that whole "all the bareback sex with my SO we want, any time" thing is awesome.

Which, again, is just how I approach feline guardianship. Don't need new kittens from them. Plenty of kittens out there that need to own their own human.

i get it

so "he went to alpha centauri"/ "he didn't leave at all" isn't known until you interact

there's no guaranteeing you go anywhere

schrodinger's rocket ship

yes, agreed. the idea of keeping anything larger than an atom entangled for anything longer than a second over any distance over an inch seems like a colossal almost impossible task with today's technology

i was only doing a thought experiment

in the realm of way out there then: i wonder if you could entangle a number of "copies" of yourself: dozens, hundreds, millions

you just sort of disperse throughout the universe (not interacting with anything, i know, basically impossible by today's standards)

but in an instant, if you, or someone outside, decides one "copy" of you should be the one that coheres at a given place: boom, you're there

just an interesting thought with interesting ramifications- you (or someone else) doesn't have to decide out of dozens or maybe thousands of destinations... until the very last moment. that's a pretty exotic form of "travel"

it's called desalination and it's a common mundane technology

http://en.wikipedia.org/wiki/D...

"boiling the oceans" makes me think you have no fucking clue about the kind of scale we're talking about here

if every nation exerted every single drop of it's GDP building desalination plants, we wouldn't make the tiniest of dents in the oceans genius

exactly

or fire risk

dc is less safe for both shock and fire

if they desalinate ocean water for drinking purposes, the question is what to do with all that salt

answer: process it and take out all of the economically important trace elements, not just lithium

The total lithium content of seawater is very large and is estimated as 230 billion tonnes, where the element exists at a relatively constant concentration of 0.14 to 0.25 parts per million (ppm),[40][41] or 25 micromolar;[42] higher concentrations approaching 7 ppm are found near hydrothermal vents.[41]

http://en.wikipedia.org/wiki/L...

sure, this would put lithium at a high price point, but not that high if the desalination and concentration process is mostly solar powered and on a massive scale for drinking water purposes

...a $350 Android phone is a high-end device--or, at best, at the upper end of mid-range. Roughly 60% of Android phones retail for $200 or less. (http://www.idc.com/getdoc.jsp?containerId=prUS25037214). The $350 price point lands right near the top quintile of all Android phones. By contrast, there does not exist a low-end iPhone for sale at retail. That's a conscious decision on Apple's part, and matches their overall M.O.

Your phone is not one of the low-end phones that give such a bad user experience. Your phone is quite nice--and quite expensive--compared to the fleet of Android devices as a whole.

i understand that

but if there were some way to make sure the two "copies" do not interact with anything. i didn't say that was remotely possible today, or perhaps ever. just a way out there thought experiment

i get it: they are guaranteed the same white noise, which is fine for encryption purposes (and know if someone snooped, because that would render their white noise dissimilar)

but there is no preserving the integrity of a particle/ wave for transportation purposes

thank you, i learned something

...well, that's sort of one of the features of Android. It's open, and it's run-on-what-have-you, so it should hardly be surprising that a significant chunk of the install base is running on cheap, low-end devices. It's a big part of the reason Android has such a large market share compared to iOS.

If Google can't pull low-end Android users onto high-end devices instead of iDevices, well, that's partly a failure of marketing, and partly the natural challenge of living in such a diverse world of devices. If a significant chunk of your market share consists of budget devices with bad user experiences that are targeted to non-technical users, you can hardly be surprised when those users clump the OS in with the phone itself.

isn't quantum entanglement a burgeoning field in quantum cryptography?

http://en.wikipedia.org/wiki/Q...

quantum key distribution would not be researched if what you say is true

yes, only a collapse to a single frame of reference according to physics

but, for the intents and purposes of outside human observers, haven't you instantly blinked across light years?

it's a legalistic, semantic cheat, but... it "works"?

that's an excellent analogy, thank you

and you are correct, there's no real movement, only a collapse to a single frame of reference

however, for the intents and purposes of outside human observers, haven't you instantly blinked across light years?

we have no technology remotely capable of this, but:

1. a quantum entangled version of yourself moves away from you (at "normal" speed, less than c)

2. say... many light years away (i know, i said we have no technology remotely capable of this, bear with me here, just a thought experiment)

3. the "copy" of you can't violate c, but at the last moment, one version of you interacts with its surroundings, collapsing you to that single copy. such that you have achieved instantaneous transportation across light years of distances

doesn't that happen faster than c?
