robots will be able to design almost all kinds of products. They will be able to design every possible version of the tool/machine then virtually test them all to decide the best. Besides who says a robot can't do it the human way aswell, once we get a bit further with neromorphic chips they will be able to use best answer instead of right answer, and considering the chips can be run 100 times faster than a human, the machines will have a huge advatage. Besides i see plenty of people in society that are incabable of anything more mentally draining than digging a ditch (they dig great ditches but don't ask them to design a new kind of bridge or dishwasher). You will need stuff for people to do but i think you'll retain a similar number of ture creative people. Real problem is, who is paying all these billions of people, when all the real work is being done by robots (probably owned by google), communism is evil remember.

Am i the only one here that thinks android apps are barely passable as software. If you manage to find one without insane access rights, it's either complete crap covered with adds, or they charge you $5 for something you could do on windows, mac, or linux for free in much better quality. The last thing i want is android apps on my laptop, But if the pc makers think this will save the industry, who am i to judge they are obviously very intune with the market (not like they needed intel a chip maker, to hold their hands and help them make ultrabooks). Screw android apps just give me a high res screen, very decent graphics, big battery, and relitivaly thin profile while leaving all my ports where they were.

show me one piece of supporting evidence for your claim of zero potential difference charging. If you could charge something using the exact same voltage what would decide the direction of power?

also of course i remember where i work, i'm going back there tomorrow, so expect to get a bunch of AC replies (i don't think they have /. accounts) from my friends when we all have a good laugh about this.

If you can disprove anything in my last paragraph (i would say anything i've written, but i don't think your grasping this at all, and want to limit the stupid replies you give me) i have a prize for you, my electrical egineering degree (because you will have completely changed electrical theory, and it will be worthless). By the way, you telling me your imaginary physics proffesor said so, isn't disproving anything, show me some citiation (hell, order the book from amazon, it's going to say i'm right).

The charger isn't being hooked up in series, the phone battery and the phone internals (processor, screen, modem) is connected in series (which is why the battery and the phone gets the 5 volts it needs from a usb plug). Try taking the battery out of your phone (if possible), then plug it into the charger, you will notice nothing will happen. This is because, power flows from the power lines into your home, through diodes and transformers, into a some kind of plug, THEN INTO THE BATTERY, THEN INTO THE PHONE (that is how series works, one then the other, different to parralel which is both at the same time), then from the phone internals back to the battery, and then back to the plug and charger to complete the circuit. The phone and battery being hooked up in series, has absoultly nothing to do with which way the charger is hooked up (you still need to connect positive to positive and negitive to negitive) it would be the same even if you connected your phone internals and battery in parralel (although then you would need twice the volts to charge (because the voltage is being split between two sources) then as your battery got close to being fully charged, the internal resistance of the battery would increase, so you'll be sending more and more volts straight to the phone (which could blow it up)).

Power flows from the source with the highest potential; nothing will happen if you manage to connect two voltage sources that are exactly the same; when you charge your phone, all the volts go to both the phone and the battery, it is the amps that get split between the two; check it out with your physics teacher if you don't belive me.

HAHAHAHAHAHAHA, you need to go back to physics school my friend. The phone and battery will be powered in series not parralel. I can absoultly 100% gaurentee you that to charge a phone battery 3.3 volts (although fresh of the charger that will be higher) you use 5 volts practicaly straight from a usb plug (you can charge it without the phone with the same volts), it works because there is a potential difference (how quickly the battery charges then depends on the current). Its the exact same theory as on the electrcity network (over here standard voltage is 230v although average is over 240v) which is pretty damn close to the way we teach kids about volts being pressure, and amps being diameter. I'm going to have a good laugh about this with the guys, when i get back to the power distribution company i work at (in the metering department) on monday.

Power flows from the source with the highest potentinal (you can think of voltage like water presure in a hose). When you charge your phone battery (3.3volts) you use usb power (5volts +- .25volts). If you tried putting exactly the same voltage as the battery in (which is next to impossible in practice, one source would always be slightly higher or lower than the other) there would be no potential difference and nothing would happen, it may as well be an open circuit. It's the same for the electrcity network.

Well, now that australian utilities companies don't sell electrcity (they only move it around, electrcity retailers deal with all buying and selling of power) the utilities companies would very much prefer the voltage to be lower rather than higher (because it's much easier on all the expensive transformers and switchgear). I've seen the volts that high and i can guarrentee it wasn't because of equipment in the network, so these solar inverters of yours arn't working properly.

I would be using the superconducting material to make super-duper-ultra-capacitors (it would mean amazing specs). But your idea is quite interesting, surely there is always somewhere in the world with plenty of sun shine. It may not be complete fantasy; Have a search for stanene (2d tin) it's meant to have 100% electrical conductivity at up to 100 degree celcius.

We do that in australia by letting anyone with solar generation jack up the network voltage in order to backfeed. It's causing massive problems (mostly around retirement homes) because the network is operating at around 270v in the middle of the day, in a suburb with lots of solar (should be about 240v). Thats the other thing, we don't need all this extra power in the middle of the day, we need it at 6 oclock at night when everyone turns on the big screens and ovens. It's not a good soloution, and thats a big part of why you cant get a good price on solar generation any more (used to be 44cents per kwh, now its 8cents per kwh). We need a new long life battery technology to use solar properly if you ask me.

The problem is to backfeed into the network you need a higher voltage than the network, and if alot of people are generating they are each steping up the voltage. I don't know about hawaii but in australia we have parts of the country (places with lots of retirement homes) that have the volts up around 270v (you will start to blow 240v stuff up around there). It also isn't an easy problem for utilities to solve as you would need to dynamically step down the voltage for the whole block (depending on cloud coverage). Energy storage seems like the answer to me (we need better batteries first ofcourse) then you have no impact on the network and no power bill.
