  • A relay switch could work. You would put the car 12V and ground across the coil connections, the 12V on the NO connection, the panel on the NC connection, and the power pack on the C connection. Make sure you get a 12VDC relay.

    Are you going to have the panel installed permanently on your car?

    Definitely don’t connect a 24V source directly to your cars 12V system. There’s a good chance of frying something important. A fuse would not protect from overvoltage so don’t rely on those to protect components.


  • I lived in an area that was going to start strip mining for sand that was the right consistency for fracking. Plenty of conservatives were amongst the loudest opponents. There’s plenty of hypocracy, no need to exaggerate. Their reasons were not wanting to have so much heavy equipment on the roads and fear of silicosis, not opposing natural gas extraction.

    I find it interesting that the hot stage jettison is after the boostback burn. That implies to me that the purpose of the jettison isn’t for weight reduction. I wonder if there are aerodynamic control reasons to jettison the hot stage.

    I also wonder if the hot stage ring is expected to sustain enough damage to be a single use part anyway.



  • Plus all the helicopter pilots for remote industrial work. Have you seen the logging helicopters? There’s helicopters for inspecting and servicing electrical transmission lines. Some power companies use giant dangling saws attached to a helicopter to trim trees along lines.

    If you only included passenger aviation, I bet the count would be below average, with most fatalities being from medical conditions while on the job.
