I let the thought grow for a minute :D It looks cool, and could be really revolutionary. The question really is how expencive it is. I didn't hear that they said any price for this stuff, but if it is at a repectable price, then I really think these guys have stuck gold. |
Hehe, you punny.
Well, with a piece of graphene oxide the size of a stamp and what a tenth of a milimeter thin, they were able to power a led for 5 minutes. By comparison, the iphone 3G battery has these dimensions:
115.5 x 62.1 x 12.3 mm = 88.222 cubic cm
In comparison this graphene oxide sheet used was
30 x 25 x 0.1 mm = 75 cubic mm
So, with the graphene oxide sheet fit into an iphone 3G battery, you could power
88,222/75 = 1176 LEDs for 5 minutes.
Anyone good in electrical science can compare the wattage of LEDs to the wattage of iPhones? Anyways I'll try.
From yahoo answers:
Low current LED's go down to 1mA at 1.8V (red) for their rated output, which is 1.8V * 0.001A = 2mW or 0.004W.
1176 LEDs would consume 4.7W
What is the wattage of an iPhone?

| Power Consumption Comparison | ||
| Apple iPhone 4 (AT&T) | Apple iPhone 4S (AT&T) | |
| Idle | 0.7W | 0.7W |
| Launch Safari | 0.9W | 0.9W |
| Load AnandTech.com | 1.0W | 1.1W |
| Maps (Determine Current Location via GPS/WiFi) | 1.3W | 1.4W |
Let's go with 1.3W for the iphone.
4.7W / 1.3W = 3.61
From these newb calculations, it looks like the graphene oxide battery would be 3.61 times as efficient as the current iPhone battery.
The cost? Well at 1500$-3000$ per metric ton which si then diluted into a base solution (not sure the cost on that) and repeatedly applied to dirt cheap CDs, this can't be costly I don't think.

Wouldn't it be awesome if ever argument could be solved with sten sax och påse? ^^

Furthermore, I think VGChartz should add a "Like"-button.

It might be easy to produce in the lab, but mass production is an entirely different matter. You gotta build the machines that does this all day every day, and they'll have to produce a shit ton of it all day every day. And then you have to interest other companies that this is the shit! Just imagine how all the oil companies (like BP and whatnot) will react if every car starts running on this - or how entire countries will react! Or all the battery manufactorers... There will be quite a few sad faces that will try and stop this. So 10 years from now is probably a bit optimistic... But I think Nintendo should get this material asap!!! But chances as Sony will try as well.... |
Like I said, Danne, the machines already exist in mass to mass-record music records. That part is a non-issue.

Rather impressive I must say. Well, if they manage to combine those two things they were talking about in the video. That is yet to be seen.

Happydolphin would be furious. He wouldn't understand if he was loosing or not :D

I don't think it's that easy... You can't simply use a CD-burner to mass produce these kind of things. You have to have the right shapes on these things and it has to be done fast in large quantities. The technology is there, yes, but right now we're a while away from seeing this on the market. And you more or less just skipped the rest of my argument...
