So - with the new Nemo overlay, have they addressed the fuel and pollution questions? Or is everything the same as it was, power wise, and they just decided it was worth the cost and exhaust fumes to keep the attraction running?

I believe a simiar system has been used at TDS in Aquatopia's load/unload area, where electricity is delivered through water, without having to electrify all of the water.

The batteries are quick-charged during the time the vehicles are in the station, enough to power the next cycle of the attraction. But this is all done above the water line, so the issue of electricity not mixing with water really isn't an issue.

This is the same system as used at the Grove in Hollywood for its trolley.
