Cities are far from obsolete. They have been an obvious driving trend since industrial revolution. Why?
Short answer: money.
Cities are where the jobs are at. Long tail effects, Minimised infrastructure costs(transport, communications, power, etc). In industrialised nations there are minimal jobs outside of cities. Farming, mining, fishing, forestry, energy are about the only significant jobs outside of cities, and a non trivial portion of those workers are transported in from cities. As sucktastic as may be living in a city slum, its better job opportunity for the sustenance level people.
If cities didn't offer jobs- people wouldn't live in them. Cities are big and will continue to be big and keep getting bigger.
Local magnetic field problematic(within low hundreds of meters)? yes. In the middle of the ocean where submarines cruise, not so much. The closer they go to an anomaly(concentration of ferrous material) the worse it will be (inverse square law and all that). Earth field stable enough: majority of the time, yes. One exception magnetic storm- but those can be forecast to some degree.
To counter problems they need inertial trackers in additionally. Better yet multiple units so they know when they are close to a magnetic anomaly.
Example similar consumer unit: CH Robotics um6.
Relevant knowledge: I have done surface(ground) magnetic surveys.
The common name you would be looking for is: Parallel hybrid electric. Except you are trying to run it without batteries/super caps which would have start, stop and burst issues others have mentioned.
The most common variant of this is the diesel-electric engine context: train,
For more information about advertising in the modern age look up Age of Persuasion. I attempt to listen in whenever I remember its on, because this program offers an amusing and informative perspective of advertising. And as the programs slogan states, we live in the Age of Persuasion.
There plans that are being implemented already for communities to consider how to get connected All found at http://www.canet3.net/ For this to be done is not hard to imagine. Telcos for the most part are charging insanely cash cow prices for really high speed >15Mb/s.
Lets pull some numbers out of someplace say ~$10million to lay fibre from LA to Seattle. charged at $100 000/month for oc3 that works out to paying off the cost of installation in 10 years, pretty good for capital investement.
So as ca net proposes why not get communities to lay their own fibre? and force the telcos to charge sane prices.
Several people have mentioned torq problems: transmission concerns etc.
Why not use hybrid? Hybrids use electric and batteries and a generic heat engine. For this all you have to do is replace the typical infernal cumbustion section of the hybrid and replace it with his Rotery Engine.
Hybrid type systems are equivilent to programming language wrappers: You have a base system that you can recharge and power the vehicles motion, -- Your basic functionality. Then you wrap the actual code/engine that with an abstract class, electricity in wires is pretty generic.
You then power the system with your engine of coice: Infernal cumbustion, Wankel rotary, McMaster rotary, nuclear fission, fuel cell, biomass, propane, methane,
So why would the article say that he tries to surpass it? Hybrid would be very complimentry.
McMaster's ultimate goal is to displace one very entrenched technology -- the internal combustion engine -- while leapfrogging other, more experimental ones, such as gas-electric hybrid vehicles and those powered by fuel cells
I think that hybrid types are the way of the future. Even though they have increased complexities they do have higher efficiencies, and they are easier to experiment with.

Person with this tech embedded in their fingers:

#Hopefully this is not too redundant.
Then just install a unix variant. They don't mind running headless!

Your Plastic Companion will now be able to either give commands where to be caressed or give response based on location/style.
For your Aibo of course. What? thinking of some other product?

Now if we actually had a system that could correctly interpret schnitzi's response, then we would be close to the "real thing".
You (other nation-states) should consider what Canada plans:
Gigabit Internet To Schools And Homes by 2005.
There plans that are being implemented already for communities to consider how to get connected
