Yes, things are changing, Chuck. However things change, there will still be increasing pressure for efficiency and alternative sources of energy. It seems these pressures are spurring a good deal of technological development.

Yes, it will be interesting to see what happens with the development a natural gas, Bobjengr. We have a number of busses where I love that are powered by natural gas. I understand it burns cleaner than oil, not sure by how much on a mile-by-mile comparison.

Public tranportation makes a lot of sense in some large urban areas, William K, but certainly not all. And probably not in a lot of suburban and rural areas. There's nothing worse than standing on a corner in January, waiting for a bus to show up. As in your case, it doesn't work for everyone.

High gas prices
William K.   7/23/2012 9:56:58 PM
Natural gas is a very good choice, since not only is the technology fairly mature and the hardware quite available, but also because there is a lot of natural gas available. We export natural gas, in fact. 

The logistics of refueling would be a bit more complex, since those folks who can't work a gas pump properly would never be able to figure out the CNG connection, but  gas fueled cars would be a good way to go. Couple them with a good start-stop engine control system and fuel consumption would drop a lot. Plus, the emissions would be reduced.

Of course, pumping up your tank at home could also be possible, with the right compressor, but those do cost a bit. Some folks might get upset about having a tank of pressurized gas in the car, but it should not be much of a hazard. It would probably be safer than the gasoline tanks because they would b smaller and much stronger. The challenge would be collecting our huge road taxes on gas pumped at home, since it is also used for heating.

Nissan Leaf: Batteries not ready for prime time
EmbeddedDesigner81   8/1/2012 11:40:55 AM
Looks like Nissan Leaf owners don't like the range they're getting from these expensive battery-powered cars.    Not only does this make no economic sense, little environmental sense (given the trade-offs), but it's becoming clearer that it makes no practical sense to drive an electric car.
