  • They’re also more expensive than regular copper or aluminum wiring, and in this case I suspect that their required proximity would be a downside.

    I think I’m going to have to say “citation needed” here.

    There are different grades of fiber optic cable, but for short distances you can generally use the lowest grade, so that’s probably what would be used if they were just components in a device, and that stuff is dirt cheap.

    On the other hand, currently audio equipment tends to need higher end copper wiring, shielded cables, gold plated connectors, etc. digital interfaces are much less demanding of course, s/pdif or HDMI for example.

    As for your comment about being vulnerable to drops and bumps, yeah I think you’re certainly right about that. And honestly, there are some other potential issues with the idea too. Foremost, a microphone like this would probably require a whole lot more analysis and signal processing than you really want for a simple audio input.



  • Oh no… You absolutely can’t be doing maintenance on an escalator while people are walking on it. Not only unsafe, that’s just not going to work at all most of the time. The maintenance crew and the public would be in each other’s way.

    On the other hand, when it breaks on a Monday, and the crew says they can be there to do the repair on Thursday, that means that it’s safe to use the escalator as stairs for a couple of days while you wait.











  • I mean, airplane brakes probably have about a 3% duty cycle (the percentage of time they’re in use), so they’re generally idle. For city driving, car brakes probably have about a 25% duty cycle.

    If those numbers are close to accurate, that means planes are using their brakes about 10x less than cars.

    BTW, I didn’t pull those plane numbers directly out of my ass, but they’re definitely a rough estimate. I’m figuring about 5 minutes of breaking time per flight, counting landing and during the taxi to and from the runway. And I’m assuming a 2.5 hour flight, figuring that could be close to an average flight time.
