Per current LPP estimates an electrode assembly might last a month.

Also per LPP estimates it will take about 9 hours for an FF unit to “cool down” to less than background radiation levels. So that’s ~9 hours cooldown, plus a couple of hours for unbolting and replacing prefabricated solid metal components. (And any other maintenance that might be needed by that unit.) Close it up and start it up.

So, given currently available information, unless actual electrode life turns out to be measured in hours and not weeks then erosion isn’t going to be a show-stopper for FF plants.

These are good news.

But what about the cost of the cathodes? If all the energy of the earth is secured by “Focus Fusion”, then what about the supply with cathodes. Could there be problems with the resources? Can you recycle the used cathodes somehow?
