Thanks for the interview with Mr. Lowenthal, it was great. It is really nice to hear from someone that is very down-to-earth.
It is a refreshing to hear from someone confirming that it might take 3 days to charge a Tesla on a standard outlet but it can be fully charged in about 3 hours with one of Coulombs charging station. These numbers make sense and make clear that the problem is the size of the pipe, not the battery.

This is an issue of PHYSICS. At 220 volts, it would require 1400 amps to charge the car in 10 minutes if it has a 50kWh battery. There are no two ways about this. What kind of a house has 1400 amp service? 100 is standard for many homes, 200 is generally the most you'd have. And you can't use all your amperage for charging the car unless you turn all the power off to everything else in the house.
I watched the video on Coulomb Technologies website and now I am confused about the connector.
The video seems to show a standard 110V household outlet, not some new J1772 connector. Perhaps someone knows what is going on there.
ThanksJohn C. Briggs
John, the new J1772 connector was announced only a few month ago... I wonder if their video is older than that. Richard also said his chargers have both connectors, so maybe they were showing only that one.
Bo, Thanks for the hint. With that push, I found the info on their website.
They sell a version with the standard outlet (NEMA 5-15) and a version with the new J1772 connector. Interestingly, the locking door is only for the standard plug. I am not sure why that is.
LaterJohn C. Briggs
PS the can charge up to 220V 80A, that is almost 18KW. So you could get 18KWH in just one hour at the charger. Very Nice.
Preliminary Specifications
CT1000 110v Only (Level 1)
CT2000 110v/220v Dual Mode (Level 1 & 2)
Level 1 Charging 110V at 15A; NEMA 5-15 outlet
Level 2 Charging 220V at 15A, 30A, 80A; J1772 connector
Where do you put the links associated with podcasts?
You should include them on the page with the podcast!!!
Hi Bo and Ryan- good show today, and good interview with Mr Lowenthal!
Interesting, the news of the Akron Engineering students working on the NMG2- the link to the story is: http://www.thesuburbanite.com/news/x1589174433/UA-students-develop-components-for-next-generation-vehicle
Oh Bo! Where is the love for Venture One! They have not been around that long- maybe 3 years? And they are not the first to have delays in getting their EV to market- and their design is a tad more complicated. As for their name- well, their vehicle really did not have one before - it was only a working name, until they recently settled on the "Persu" name. There have been changes though- it looks like one of the co-founders, Ian Bruce, who was the face and voice of Venture One, is no longer with Venture One- but at least this does not seem like the acrimonious split we saw at Tesla- at least, not yet;-) This car still remains at the top of my EV wish list.
Daq, And you should learn to say "please".John C. Briggs
The students working on the NmG2 are all Electrical Engineering and Computer Science students!!! Don't you think at least one Mechanical Engineering Student would have been helpful?John C. Briggs
Can I *PLEASE* get the link to this bogus-sounding new "Hi Trick"(spelling?) EV company?
Edit: Thanks Bo! (And it would be greatly appreciated if you put the links to various things you talk about in the notes with the podcasts . . . I know you guys are busy but it shouldn't take more than a couple minutes.) :)
Edit2: Wow . . . yeah, that looks pretty bogus. It sucks that the EV market is filled with so many hucksters. :(

Carver, VentureOne-> Persu
Lots of company names but no vehicle for sale.
Edit: I stand corrected (on the company names).
No Dag- Carver is the Dutch company that makes the ICE version for sale in Europe, and who licensed their 'leaning' technology to Venture One, but only for EV and Hybrids, and only for North America. And the Venture Once was never intended as the name of their vehicle- they even took input from folks on their web site for awhile on what the name should be. In fact, that is another one of the changes that Venture One has gone thru- no more free-for-all gripes with impatient bloggers on their site. Now, I am not saying they will make it- unfortunately there are going to be many, small, would-be EV makers who are not going to- but their recent naming of the vehicle and the perceived delays in getting to market are not yet enough to condemn them to the junk-heap just yet. We'll know more about them, as well as others, by the beginning of 2010, I think.
