- LinuxBender 3y agoThis is not quite true. All ground rods have resistance and are supposed to be tested with a megger and documented to be below a specific ohm rating. With time they gain resistance and some of that energy will be induced into nearby objects, notably anything with electrical properties. In this case we are talking about a concrete that stores and conducts electricity. A lightning strike can be over 1,000,000,000 joules of energy. Some of that will be induced into that special concrete. Regular concrete can heat up and fracture which is mostly harmless but I would like to know what happens with this special concrete.
- hnisg4y 3y agoWell the article says it's made of material that wouldn't catch fire if that's what you're specifically Wondering. Presumably smart people would be insulating the battery from an external surge like a lightning strike. However in practical senses the lightning would go into the rest of the ground as the grounding wire would be bypassing the concrete.
