A good question, especially unforeseen 'tech mistakes.' We can see Tesla sitting below a Tesla generator reading a paper with 'lightning' flashes all around him. I don't think that I would feel comfortable with those flashes all around me...
Presumably in order to 'consume' that power one would need a Tesla Coil... available at your local electric company for ❓🤔 💰 😉 etc., etc.
Still, if they are doing it successfully in Europe - let's see how it works out!
