Nano Power for Nano Devices Patented

lperdue writes "Scientists at the Univ. Oklahoma at Tulsa have come up with a microscopic battery just a thousandth of a millimetre across ... and rated at a millionth of a milliamp. It's still a lab experiment, but then so was the semiconductor at one time."

      I think the better thing is that you could spread it out over a thin sheet instead of making the battery shapes of right now. Like you could cover the bottom of a laptopcase with them. That is just my two cents.

      yes, I know you are right and I agree. I was using the same units as the original piece from Nature ... I would guess that Nature was going for the largest possible comprehension level -- aka "dumbing it down."

      It raises issues of journalistic judgement. I assume that slashdotters will all understand micro- nano- and pico- but what happens when we get into femto- and atto-? Likewise, we know mega- giga- and tera-, but what about peta- and exa-?

      Again, you're correct but I think that Nature opted for maximum comprehension.

      Alright, I'm sick of people not knowing the metric system. (Rant coming on...)

      I think that some basic knowledge of the metric system is just one of those things that people need to know. It isn't that hard! Atto- through exa- is a decent range to know, and for most values you will be covered. Conversion is trivial if you stick to normal units like kilo- and milli-, and don't get into units like centi- or deci-, and my TI-82 even has a mode to give scientific notation answers with convenient powers of ten, like 10^-6. How could you fail to love the metric system?

      The more you dumb it down, the dumber people will get about it. That said, though (end of rant) I don't blame you, and I'm only slightly peeved at Nature.

    It's not a microscopic battery. From the article:

    ...For this reason, some researchers feel that it is premature to describe the set- up as a battery.


    Also, the title is misleading. "Nano Power for Nano Devices Patented" sounds like the idea of having any power for nano devices has been patented. It's not that. The researchers have simply come up with a method to produce a structure that could be used for the purpose. There are undoubtedly numerous other ways of achieving this same goal. They're just one of the first reporting one to the mainstream press.

    You've obviously never talked to anyone outside of the state. I worked for Creative Labs tech support in Stillwater for a year and heard it all. The first post was very accurate.

    Liking Oklahoma City and Tulsa at the same time is impossible, especially if you live in Oklahoma.

    Ironically, the two previous posts accurately reflect the respective attitudes of Tulsans and Oklahoma City natives.

    I lived in Oklahoma for the last ten years, and now live in Japan. Change is good.

    Man, this is so far off-topic now, but I'm originally from Tulsa, so I'll throw in my 2c.

    Tulsa is a piss poor laid out city. 99% of shopping is off 71st and Memorial (congestion is worse than at Sam Moon in Dallas).

    What a sad situation! My family moved to Tulsa (Owasso, actually) in the late '70s, just before Woodland Hills Mall came in at the aforementioned corner. Up until I left (mid-80s), the city's layout was nearly ideal... the entire city is laid out on a 1-mile grid, so you can get anywhere from anywhere else without getting lost.

    But as I was leaving, the new mall at 31st and way-past-Mingo was going in, and from your posting, it sounds like things have only gotten worse from there. The one-mile grid was perfect when all your needs could be met within two miles (I lived a mile from Utica Square). Now that mall culture has hit, the same urban sprawl that has choked Dallas appears to have afflicted Tulsa. Pretty sad.

    Speaking of Dallas (where I live [outside of] now), what the Sam Hill is "Sam Moon"?
