D: I proposed the use of magnetic nearfield bubbles some time ago. There 
would be no physical connection just a send and receive chip. Similarly, 
couldn't a transformer power external equipment like lights? Or the external 
(to the passenger compartment) motor power supply could provide said power 
to the passenger without a physical breach? Even thru plastic to prevent 
metal heating up might work.

PS - anybody wanna see 8000psi (compressive strength) seacrete sphere crush 
depth? <: It would take years to grow. You know, military subs go c. 2000' 
down and torpedoes 3000'. Could get BELOW them... wais limit on mines? I'm 
writing a sci-fi story about it.
