The logistics of the electric vehicle are the obstacle that stands in the way. The problem is fundamental physics: it takes quite a lot of energy to drive a car, and you must put that energy back into the battery sometime, or you stop. EVs are fine if only a few people on the block have them, but if there are a lot of them and they all defer their charging until the rates drop, then there will probably be an overload at the local step-down transformer. In order to handle everybody's electric car we would need a lot more distribution capacity, which is not cheap. The alternative is some invention that uses magic to cause the battery to "somehow become fully charged". Making the cars more efficient is going in the right direction, but the laws of physics still hold. So perhaps some kind of fuel cell, especially a fuel cell that could use hydrocarbon fuels directly, would be a better solution. A fuel cell that ran on diesel fuel would be the ultimate solution. So why not push research in that direction?

To contain pollution and to improve the efficiency of energy use, EV seems to be the best solution. I agree with Bert that having no garage and no electrical outlet at work would be the major stumbling block for NA to move forward. Parking lot charge station would be ideal. The extra revenue bring to the property owner would be a great incentive. Yet, the ultimate problems are how to charge and at the same time how to charging being stolen. Before finding a solution to the problems, regulation of deploying charge meter to parking lot shall be developed by government. Leaf as well reveals another issue which is lack of mileage. Driving 200 miles is just not enough for NA. At this point, hybrid car seems to be better solution until the advancement of battery technology and the readiness of infrastructure.

In England we used to have electric buses (Trolleybuses) that ran off 2 wires above the road with poles to collect the current. This could charge-as-you drive on the freeway but the possibilites for chaos are of course endless with the average public.

The recent article on the Nissan leaf brought up this charging problem. Especially acute if you don't have a garage or at least a home with off-street parking. When away from home, e.g. parked in the garage at work, I think the benefit of a smartgrid would be primarily for identifying the car and charging (pun intended) the driver for the juice. However, drawing lots of power from the grid during the work day is certainly not ideal, from the standpoint of power generation and distribution. That's when electricity demand is at its peak already. And communities are already up in arms about allowing the electric utilities to erect more high tension lines in their neighborhoods. So I think people need to do some more analysis, before jumping on this battery-powered electric car bandwagon. These plans for 230 VAC outlets at shopping malls and everywhere else just seem unlikely to me. I'd be looking more seriously at storing the energy as a liquid hydrocarbon fuel, just like any car, and then separating the H2 on-board, for use in fuel cells and all-electric drives. That would bring electric cars to the realm of the probable.

One can only hope that a similar trend will show up in North America. Is PLC part of a standard in the US for the Smart Grid?
