Hey guys -
I don't think the story about polar bears is sensationalism. See 'Arctic Tale,' a film made by the National Geographic Society in 2007. The habitat is changing for the bears, because the ice is dwindling lower than it has been since records have been kept. On the flip side, I am curious to check out the evidence that the polar ice is greater than in past decades.
By the way, the Volt is not the only "series" hybrid out there. I think you could also consider the Aptera hybrid in this category (although it's not classified as a true car, since it has 3 wheels).
I found an informative link about Prius conversions other than Hymotion. In case you haven't seen it, it's here: http://www.eaa-phev.org/wiki/Prius_PHEV#Kits_and_Conversions
I specifically mentioned the Hymotion because it looks like one of the most affordable conversions, and they're taking orders now.

Hey Guys, love your show. I'm a Dane and I got a correction for you. Bjorn Lomborg (Bjørn Lomborg in Danish) is not from Austria but is actually a Dane. Keep up the good work.
You can compare sea ice on different days at this wonderful website.

2007 was a record low in sea ice. Interesting to watch how low it gets this year. Imho, the increased albedo of land-use such as farming and black pv panels may lead to more global warming than CO2. Historically we have 70,000 years of ice age and 10,000 year of inter-glacial period. During the glacial period virtually all of Canada (except small area of the Yukon) along with many parts of northern United States was under ice. IMHO, melting of the arctic ice may be the trigger to the next ice age.
If you google Nothridge and click on the map, virtually every street there is 40 mph or less. Virtually every street in Los Angeles is 40 mph or less. Mid speed electric vehicle would be adequate for many if not most people in Los Angeles as I know many people who never drive freeways.
Just listened to Podcast #10, and heard a user asking about the vehicle-to-grid system, wondering how it would work - why try to charge your car and come back and find it's flat because the grid's taken the energy.. Bo and Ryan were also struggling with this.
It took me a while to figure out the vehicle to grid scenarios, too, but it makes sense, assuming that when it happens, the vehicles will most likely be able to generate their own engery.
Off-peak, the vehicle can plug in and charge.Peak-time, the grid takes power from the vehicles, and those vehicles may have solar panels, or some kind other of charger engine (maybe petrol, or wind-based).
Anyway, that's my 2 cents.

Here is what I just posted on the same subject in another area:
** 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.
