The original question was: Would it be possible to create a very dense cloud cover inside a laboratory under controlled conditions and generate “artificial lightning”? Physicist: Lightning is generated in the same way that static electricity is generated when you drag your feet on a carpet. It is entirely possible to create static electricity, and even lightning using this method. This lightning is generated using capacitor banks (not rubbing stuff together, the way natural lightning is created) and is feeble by comparison to the real thing. Also, it isn’t used to generate power.
