Probably a stupid car question...

From a practical standpoint, you would need specialty mechanics, perhaps certified by the government, to work on your car as these "nuclear" run mobiles started slowly replacing standard carbon-emitting automobiles, but I'm sure the trade-off would be slow as the initial prices for such cars would be astronomically higher priced than a standard car as the technology lagged behind the science.

I spend about $100 per week on gasoline, or say about $50,000 over ten years for fuel. Figuring that 200 HP = 0.00015 gigawatts,

Using: http://www.wise-uranium.org/nfcc.html ...and, assuming I'm reading the results correctly.

It would take about 100 pounds of uranium ore to power the vehicle for ten years, and using fully processed fuel and accounting for disposal costs would cost about $20 for total fuel costs over the ten years.

That’s now what I meant! Of course the fuel efficiency would be cheaper, which is how this branch-off topic started. What I'm talking about is incorporating the technology and science into practical use for the everyday car. There are many examples I can think of with technology (such as video game consoles, cell phones, solar panels) where the cost to produce such items was extremely high when it first came out, even though the science behind it was pretty straight forward. Only after years of development did all the ducks line up where the cheapest manufacturers plus raw materials were chosen, where supply beat out demand and mass ordering reduced initial startup fees, etc, etc. I'm sure the initial cars for the first few years would be several thousand dollars more expensive than the standard cars of today, like how electric cars were, although electric cars are slowly inching down in price as their technology becomes more used. There would be many fees, new regulations which would be expensive, and oversight. $50 Smog check? Nah, get your $200 Stability check. And if not enough people could afford these new vehicals, then price would not go down significantly meaning either 1) The market would dry up and this idea would die a quick death, or 2) It would take long time before the prices went down where your everyday Joe could afford one, so the real changes would not take place for over a decade or more until its the projects inception.
