Great project, I wish you well. ( Or less "wells" I hope. Please look over my website especially the article, URL above, concerning Battery Exchange systems. I think it would be an additional asset to consider this in your plans. BTW I design high performance electric motors and am an EE .

Shai, Loved your talk at Stanford. I would like to share with you two projects: One that addresses the fact that 80 % of electricity is consumed by buildings, with the next story in wind. The other addresses reaching Mideast peace, through trees, out of San Francisco.

We feel that you would "get" these approaches and would like to share them with you.

Please let us know.

my roots run deep both in Israel and physical sciences. so already for free, well almost free i will point out some potential errors in your "fuel". i am somewhat confused that no chem/phys/chem has pointed out recent published research, what i've dreamed of doing since i rcvd my first chem set. if you can conjure up someway we can communicate with security, i think you may find my comments unusual and valuable. 70yrs in chem&physics/dsc/phd.


vallahi ne dedigini anlamaya çalıştım ama bir sey anlayamadim. umarim daha acik bir dille anlatirsin

The California Energy Commission has published in August 2007 a detailed Well-to-Wheel (WTW) research comparing energy usage and GHG emission between the different car alternatives.

The bottom-line (as related to the discussion in this forum) is that EVs are about 60% more energy efficient than fuel powered vehicles and about 40% more efficient than Hydrogen cars. They are about 60% more GHG friendly as compared to cars propelled by fuel and 30% better from that perspective as compared to Hydrogen cars.

It is a much elaborated research so here is the link for those who want to dig deeper - http://www.energy.ca.gov/publications/displayOneReport.php?pubNum=CEC-600-2007-004-REV.


Hi Shai,

I'm a undergraduate in the National University of Singapore. I love the youtube video that you guys have made for DAVOS, and I think it brings along the point of the project very well.

Other than electric vehicles, various other alternatives like fuel cells and compressed natural gas have been suggested to replace gas.

The greatest obstacle to the adoption of these alternatives seem to be the huge capital outlay in setting up refueling stations, as well as changing people's mindset about the performance of such cars.

Im just curious as to how you view such other alternatives. Are they competition to your project, or do you think there is a role these alternatives can play to complement the electric alternative?

Thank You

I think that the common sentiment (and one that I read in some of Shai’s postings and presentations as well) is that there is no silver bullet in solving the environmental crisis caused by the addiction to oil. As such, at least at the short term (I say 5-10 years) multiple solutions will be tested. However at the long term a dominant solution will emerge. Looking at it from an economics perspective as well as from an environmental one it is realistic to assume that EV will be that dominant solution. See some comparisons between the solutions (from both perspectives) in postings above to support this hypothesis. Infrastructure set-up to support the implementation of the solutions is going to be a main success driver and this is what PBP is all about.

Also, once one is in the infrastructure business it is much easier to adapt the model to new technologies and circumstances which will allow PBP to be much more flexible in maintaining its competitive advantage.

BTW - a supporting evidence of the fact that several approaches are already in the process of being deployed is the new environmentally friendly campaign Chevrolet has just launched (lots of $ spent on Super bowl ads yesterday) where it presents several car models (Electric plug-in – Volt; Ethanol – Avalanche, Impala and more; Hydrogen – Equinox).

Hi shai,
I think that I have something that might intresting you please just send me your email address and ill get back to you with all the details, also you can give me your phone no. that i can call you and have explane you everything.

best regards

Why? I am intent on commercializing a 150 MPG “MFSD” a multifuel Superior diesel, MFSD runs on diesel, gasoline, bio-fuels, ethanol, etc. And, a $.05/kWh renewable “Next Generation” energy systems. The math works, virtual works, POC works, fortunately physics, chemistry and math work for obscure folks from Queens, (PS: Do you think the $1 Trillion / year automotive industry wants efficiency such as 1 moving part brushless AC motors designed by N. Tesla almost 100 years ago? Or plug-in/out motors, standardization, even LED based lights that last 10,000 hours? JRIAM1945@aol.com

I know that we usually focus on OPEC and other oil producing countries, many of which are very happy to see us totally hooked on oil and gasoline powered vehicles.

Look to Canada though if you really want to see how crazy things are and what lengths we will go to get that black gold. Canadian energy firms are extracting oil from oil sands at a cost of $50 a barrel. I guess they don't think the price will fall that much in the future. They also use water and natural gas to do it. The article at http://www.millennialliving.com/content/higher-gasoline-prices-what-carmakers-really-know
exlains this in detail.
