You can turn a Toyoto Prius into an all-electric vehicle by making its battery bigger but charging it from the grid will be tricky, that is unless you get in on a pilot program in Austrailia where the "Electric Driveway" was invented. Look for Austrialia to offer smart meter support for all-electric cars within two years. R.C.J.
Australia is aiming to become the first country to integrate electric cars into a nationwide smart grid. own under electric vehicles are harnessing plug-in hybrids to not only reduce greenhouse emissions and lower transportation costs, but also to make smarter use of energy from the grid by charging at night during periods of low demand, then supplying any excess charge back to the grid during periods of high demand during the day.
