Youtube user Photonicinduction shows how to erase a CD using a high voltage step up transformer. It’s probably not the most efficient way to go about things, but it does look cool! [Thanks, Matt!]

  1. I’m fairly sure the reflective layer necessary for read/write operations is being vaporized, leaving a nonfunctional translucent plastic disc.

    Very neat either way.

    1. I think that’s what’s meant by “erase”. the goal here seems to be to render sensitive data totally unrecoverable, same idea as melting your hard drive with thermite, etc.

  2. A stationary motor such as a winch is easily provided with a supply of power, but a motor that moves with its application, such as an electric vehicle, is obliged to either carry along a power source such as a battery, or to collect current from a sliding contact such as a pantograph, placing restrictions on its range or performance.
