Re: Carlsberg doesn't make batteries ... #
Probably Really Light! But that got me thinking.... Let me show my complete lack of semiconductor fabrication knowledge. This involves me talking out my ass, which I am rather good at actually. So attend me while I put some unfounded assumptions out for public ridicule... (Just remember it's Christmas and if you're too rude to me you'll only get coal. Although you can burn your coal so that might be good.)
The article talks of 10NM spacing. This is quite close; one could say almost immaterially close such that the electrolyte isn't going to weigh much. If we then think of it as a block of Silicone, that has an atomic weight only 2 more than aluminum. So this dubious, but reasonable sounding, logic means it would weigh something similar to the same sized block of aluminum. I've never held a laptop battery sized block of aluminum but I suspect it's quite a lot less than a Li-ion pack.
My nay-saying was more of the line, that doesn't sound that dense to me! But...
And here is where my maths probably go to crap. But if we start with 1A/sec = 6.242E18 electrons (known) this should be 1.348E23 electrons / hr for a 1AH battery. That should only be around 8E24 electrons for a typical laptop battery. (this sounds wrong so maybe I've buggered it)
I have no idea how many electrons he's planning to store in these tiny capacitors, clearly not very many, possibly even one for all I know. But still, if he's talking about 10NM, that's 10E-7M. Grudgingly, I do have to admit that that could indeed add up to a useful amount of power. So maybe he's onto something. Regardless, it's probably good for programmers to do some maths that are more than increment or decrement by 1.
