Hey Guys,

Great work - keep it up.

Feedback:

1) People in China generally speak Chinese (not Japanese).

2) The Saturn that AMP is converting is the 'Sky'.

3) How does the 'grid' work when you are trying to charge your electric car for a 100 mile drive and the grid is trying to drain your batteries during a high-usage period?

4) Don't you think that 'daily' podcasting is too much? I'm a big fan (my wife says I'm obsessed), but even I can't keep up with the daily podcasts. I wonder how others feel about it. Personally I would love to see you summarize the weeks events into a weekly - 1 hour podcast - like you originally intended...

** Except for the Japanese who live or visit. :)

** The word you left out is "smart." A smart grid with a smart V2G capable car handles all this. First we have to fast-forward to a time when we have millions of battery cars. Everybody drives to work and plugs in at the work parking lot. At this point, you are about half full, and would like to have a full charge for your drive home. Well, in the morning, it is still off peak, and the cars all happily charge away. By Noon just about all the cars are full. At 2pm, there is a local peak, and a bit of energy is sucked out of thousands of cars. This drains them to about 90% SOC. The peak passes, and by 3pm, the cars are again topped up. By quitting time, all cars are full, and you head home. One important aspect that is absolutely being implemented is a meter that YOU set in your car. You tell the V2G system just how much SOC is your minimum that you will be left with. So you set it to 90%, and even if they're taking power right before you want to drive it, it will never be below 90%. If you want them to take nothing, you set the meter at 100% for that day. They are paying you for the power. You determine how much you are willing to let them leave you with. Even if you set it to 90%, they could take out a total of 100% ore more of your battery capacity - they just keep putting it back when they can, and taking it back down to 90% if they need it.

I noticed that at one point the hosts mentioned that this is just "theory." It is not. It has been tested and proven. No, not in production, but in real-world test - controlled remotely by the utility.

** YES! an hour a day is too much even for this glutton for punishment.
