the last true eclipse one yeah. But theres a few places in the US now that have developed a way of doing it for a lot cheaper and a lot more reliably. Although they look more "dull" than the eclipse ones.
As far as I know ODD do the nearly the exact same process eclipse do, but they do something ever so slightly different to make the process easier.
Its not that 1 out of every X amount of bodies will get destroyed, thats just a rumour that was made up to make it seem more rare, its just because its an incredibly time consuming process
Most people think that its to do with a gajillion volts of electricity going through the body / parts which will destroy it but that is untrue, and if i recall correctly, it has no / low volts going through it, as its vapour something (i cant remember the correct term for 'aurora')
