Recently folks have asked me what my dream car would be. After pausing 7 seconds to think, I tell them I need two dream cars.
First, I want an all-electric small car for commuting to work and for errands around town.
Second, I want a big comfortable six-passenger car, fueled by 100% butanol made from waste material. This one is for road trips to visit the grandchildren.
An all-electric car would recharge from the wall outlet in my garage. The batteries would last long enough to get me to work and back. It would have to be at least a two-passenger model. Cargo space for a weeks worth of groceries would be the last requirement.
Yes, it would be coal powered by electricity generated at the nearest power plant. The efficient energy conversion from lumps of coal to miles driven would result in the lowest cost per mile. The cost per mile would be far lower than any liquid or gas fueled vehicle of similar size and weight. I believe that it would have the lowest total emissions per mile.
Hydrogen is far too expensive and explosive. The emissions that are produced in isolating hydrogen are a problem, unless wind, wave, solar or geothermal power is used. Wind, wave, solar or geothermal power would also work just fine for recharging an all-electric car, with out the expense and safety risks of hydrogen. Hydrogen is by far the highest cost per mile fuel of all.
Gasoline, natural gas and ethanol all cost too much per mile.
The second car would be a big comfortable six passenger automobile. My wife and I could drive for 300 miles and not be tired from the trip.
I could pack the whole family into one car for a memory building adventure with the grandchildren. The whole package would be fueled by 100% bio-butanol made from the waste from cheese making. Butanol made from waste would have a cost per mile that is lower than gasoline. Butanol is a liquid fuel from renewable sources that is a direct substitute for gasoline. The car could be an antique Packard, Rolls Royce, Cadillac or a Buick Roadmaster. All would run just fine with out modification.
Both of these dream cars are just around the corner or in a garage near you now.
