so your imagination is that limited because you think electricity and water don't mix, I guess
so we couldn't possibly run power cables underwater ------------- basslink is a fantasy, doesn't exist
diving torches - don't exist
underwater cameras, don't exist
diving helmets with comms, don't exist
electric powered underwater vessels, impossible
your imagination is what is limited - nothing more
if you think that making an electric vehicle would be more difficult than getting an air breathing ICE vehicle to do a water crossing is harder - then, I'm afraid you probably shouldn't be allowed to vote, or drive
