I am reading it works on pave stone, cement but not asphalt. Lots of conflicting info on this.

I've testes on paved stone and cement and I was not grounded.
We need to fully understand what grounding fully is.
Because stepping or toughing living matter works.
Tested this 100's of time.

Might be a dumb question but would being in the Ocean have a similar effect?

Electricity flows better in wet ground than dry, and salty ocean conducts electricity especially well. That's why everyone gets out of water when thunderstorms are getting close. Better than walking barefoot on grass is morning dew on grass or after the rain, but even better is to go swimming or surfing. Salty water conducts better than fresh water. You've got a great lifestyle! Hours of grounding at a time when surfing.

for sure
