Data cable extruded using sound die Printer Friendly Version
Forgive me if this is waffle but this idea came into my head so clearly the other night that I had to put it out there. I propose an extrusion process for data cable using an alloy of copper, gold and something like hematite or other semiconductor.
The alloy is extruded as a cable through a die with an array of point sources for sound around its circumference this array is tuned to create a standing wave within it. Similar to the waves created by Alexander Lauterwasser.
The goal is to create a standing wave within the liquid metal. A circular matrix of nodes whose concentric rings become increasingly dense in number. Perhaps each concentric ring is in harmonic proportion to the next ring. By this I mean conforming to something like the fibonacci sequence for example where at the core you might have 3 nodes then around them a ring of 5 then 8, 13, 21, 33 ...etc.
My hypothesis (this would need to be tested obviously) is that the liquid alloy would form an imprint of the standing wave on it's sectional structure which would remain as it hardened thereby creating a cable with clearly defined sectors of higher and lower conductivity. I thought this could be used as a kind of intelligent data cable whereby a signal could be sent using specific segments of the section of the cable.
Reward: A little credit would be nice, otherwise just feedback.

Auto Shut Off AC/DC Transformer Printer Friendly Version
This can work for any kind of charger, or transformer. Using the proper circuitry the charger turns off the transformer in order to radically diminish the consumption of energy when there is no device connected to it. How many chargers do you have constantly connected to the wall waisting electricity. All chargers by law should have this capability.

Tilt Wide Screens Printer Friendly Version
Nowadays laptop computer screens, even the ones intended for use in the office, are coming in widescreen. I think it would be useful if these screens could be tilted vertically like for editing text documents.
Widescreens come at a ratio of 16:9=1.77. A standard letter page is in a ratio of 11:8.5=1.29 so the length of a letter would fit nicely if put at the width of a page. Anyway, it's an idea.
Reward: just knowing that took the time thinking of me to look for something is enough
