Ultra Theory

Big Gav has raised an interesting question on suppression of emergent energy technologies. I can side with the rise of interesting storage ideas such as the ultracapacitor in part because of how much the micro-version of the lowly capacitor has steered high-tech the last few years.

In reality, what we now take for granted, capabilities such as persistent data storage, always-on clocks, and power-down state saving, have lead to a revolution in portable electronics. Things such as solid-state mp3 players have now become the rule, whereas a few years ago, users would have thrown their arms up in disgust trying to keep the things running with any reliability and without extreme care and feeding. You see, the advent of low-power consumption static RAM necessary to run these devices would have proved impossible without the reliable dielectrics that went into the solid state designs for memory. And the little bit of non-leaky capacitors that allowed clock circuitry to keep running has saved "dinking-around" time for lots of users. Lots of people would agree that dynamic RAM has done the trick for all of our desktop computing needs, but fewer acknowledge how static RAM (aka flash and non-volatile) has revolutionized the gizmo arena.

And if we can scale capacitance form the micro to the ultra in the same time-frame as the iPod has existed, we might still get some final juice out of the old reliable capacitor.

After finding a 17kw capacter as battery for 1310 (and feeling that was a bit pricy), I set about hunting up other ultracaps. MAxwell is buyable today, with EEStor getting the press this month, and LEEDS getting press in Feb of 2006.

So far, Batteries are in the lead. No disruption just yet.

Interesting also that at least a few of the big caps are being used for audio woofer applications where the need for the deep booming bass sound has become quite the cool factor.
