  • I can’t speak to the superconducting potions of this comment, but the general computing information is mostly correct.

    Switching losses are a result of capacitance in the circuit. These capacitances aren’t going anywhere in transistors made from semiconductors. Additionally, even when a transistor is on it has some resistance, which of course creates heat whenever a current moves through that transistor. Leakage current also generates waste heat.

    I could see room temperature super conductors being useful as replacements for bus lines in a digital circuit, but this wouldn’t eliminate the heat in the circuit. Most of the heat is created in the transistor junctions, so the effect would be very minimal if even noticeable.


  • A lot of these cars are starting to get massive touch screens too. I’m looking at buying a Prius and several of the trims have a 12 inch touch screen. Why would I ever need that as a driver? Why would I ever possibly want that? Pedestrian and cyclist deaths keep skyrocketing and we continue to out these massive screens in cars that in many cases can’t be turned off. Lawmakers really need to make auto manufacturers responsible for the part they are playing in enabling distracted driving.
