Is this good, or very bad?
When I first caught this article on V2G (Vehicle-to-Grid power supply) I wasn't sure.
Let's see, sucking energy from the batteries of hybrids, which are just going to have to generate it back by burning gas. For peak demands, I guess that might make sense, depending on the cost/environmental impact of building to meet such peek demands. But the article suggests sucking power back from all-electric cars. Uh, what? The power company surely can build more efficient storage means than showing the power down the lines and back (once to charge the car, once to return it to the network from the car) on-site, with batteries that probably scale better. Not to mention that it supposedly costs hundreds of dollars to equip a car with the technology to do this.
OTOH, whenever the use of fuel-cell cars becomes widespread, this might make sense. I have a feeling that home generators based on fuel-cells will actually eviscerate any demand-cycle problems far better than building cars (and parking lots) that support plugging back in. Bah.
