"None of the other power sources for cars work particularly well yet. Right now, the internal combustion engine is the best solution available. I'm waiting for someone to reply that the answer is hydrogen fuel cell and not electric."
Electric cars are fast becoming more viable. The people that discount hydrogen as a potential fuel source are retarded. Ethanol is extremely practical. Diesel is extremely practical. Gasahol is extremely practical.
The fuel source that makes the most sense, however, is bio-diesel. Bio-Diesel engines last longer than gasoline and require less maintenance. They get better MPG, have better emissions and Bio-Diesel can be produced in large and sustainable quantities in a variety of ways including algage, plant watse animal waste, recovered oils (from garbage/landfills,) waste commercial oil, waste food oil, etc-etc.
If we combined these sources we would have excess bio-diesel and cost would be far cheaper than the curr

According the author:
"The age-old problem with Stirling engines is the difficulty in getting sufficient power out of them without having a massiveï»¿ engine. Using compressed hydrogen or helium is much more efficient but requires excellent sealing. The most promising engine coming to market is the Stirling Energy Systems parabolic dish solar Stirling engine, which uses high tech and hermetic sealing of free-piston engine. The best solar to electric efficiency so far."
