As V2G goes around again in the media, I'd like to emphasize that the 'to grid' part requires an inverter with a sine waveform that is synchronized with the system. This is not typically achieved with 1 kw inverter on the Prius' 12 volt system (as Bob has done), or with larger inverters on the Prius' high voltage system (as Richard Factor has done).

This is not to dispute the obvious value of a Prius supplying 110 vac. But if somebody someday connects their Prius to the grid without attending to this matter, I fear that they will let all the magic smoke out. That would be a shame.
