What can I do to help? Forget about wages.

future EV driver

As a poster before me wrote, I think your idea about stations for recharging is good, but the idea about automatic switching is totally wrong economically.
The reasons it is wrong:
1. The cost of R&D, and the cost of the robotic automatic battery switching machines themselves will be high. Also the costs of maintainance and employees for keeping safety of the drivers near each machine will be high.
2. The switching solution is only an interim solution until a better battery will be developed that can run more than 100 miles. When it will be developed all the switching stations investment will go to the trash.
2. The reasoning is wrong. You say that recharging is for small distance, and switching is the solution for long distance driving when you can't have the time to recharge when you are on the road. The reason the switching solution is wrong is because there is a better solution for the time being - The Plug In Hybrid Electric Vehicle (PHEV) . When you are on a short distance daily driving you recharge, and when you are on a long distance driving, you use up the 50-100 miles of electric driving mode (today, in the future it will go up), and then move automatically to gas for the rest until you can recharge again the battery.
Battery distances will go up steadily with the advancement of battery technology until there will not be a need for the gasoline and the PHEV will become the EV.

I wish you good luck with all your green initiatives.

Hello Shai! I am writing you about two things:

(1) In YahooNews today, you are featured in an article about your proposal to get EV cars up and running, in part through selling replacement batteries like "phone cards"...

and

(2) a comparison of total energy

Is there an alternative to exchanging the batteries, which some folks find at the very least, awkard, say, with replacing the recharged electrolyte solution?

I am very in interested in such proposals from the aspect of total energy costs/pollution. If the batteries are recharged using conventional fossil-fuel (F-F) fired electric utilities, then we are just moving the point of F-F combustion from inside the auto to a stationary source. It is not clear to me that this path is any more efficient or beneficial in terms of reduction of "classic" or GHG pollutant emissions, or that it will make a difference in the rate of F-F energy consumption.

Do you know of any top-flight analyses of the alternatives:

F-F Internal Combustion Engine (ICEs) (base case)
F-F electric generation for EVs
F-F electric generation for H2Vs
Nuclear electric generation for EVs
Nuclear electric generation for H2Vs
Solar electric generation for EVs
Solar electric generation for H2Vs

As for the H2 vehicles (H2Vs), what about H2 ICEs vs fuel-cell?!

The popular press does a very poor job of communicating the life-cycle pros and cons for the alternatives. But the public and politiciancs need to be educated and motivated in order to move to a viable alternative. We need to know the complete picture for all the infrastructure costs and consequences, not just the vehicle itself.

I look forward to your reply/comments.

Thanks! Mike Hebert USA

To Don Ellis:
I want to give my arguments to your comments 1 &2 about wrong reasons of battery switching of Shai's future investment (I want to say so because I think his idea is NOT new since we proposed the solution some years ago and we demonstrated them much harder than what Shai will be doing)
1. If you are a researcher in robotics, with emphasizes in energy autonomy for autonomous mobile robots, you might see the solution of recharging docking station for vacuum cleaning robots, e.g. IRobots, Iclemate robots is very simple. In according that the price of such types of robots is very cheaply commercial (everyone can buy one for their home). The idea is similar to the solution of RECHARGING station Shai said.
Further, BATTERY SWITCHING mechanism might be an automatic belt system with the same technology of RECHARGING station + BATTERY CARRYING SYSTEM. A complete charging systems can be easily implemented with a cheap price if you know about the method of how to recharge a rechargiable battery. Have you seen an universal recharging device that can recharge for any types of batteries? I got a lot and they are really very cheap and safe.
In short, we have already investigated the solution of self-refueling energy and self-sharing energy for multiple autonomous mobile robots (not manually controlled cars that we think it is much easier to manage). Indeed, our ideas are much further than Shai's idea (his idea is 10% of our research run) so that I can say that R&D cost is not too expensive as you thought.
2. A switch systems (we called Battery Exchange Mechanism) could be the BEST idea because we can not see any idea to conduct electron energy faster. Why? Going through ENERGY LAWs: "Conversion" and "Conservation" and characteristics of chemical energy, you can answer them easily.
And if you are still wondering about safety of battery exchange process, the answer comes from engineering of electronics circuits for battery switching, battery recharging, etc... They have not been problematic so far and we solved them in days

In addition with my argument 1, I think Shai's investment may promisingly change our polluted world into green one. However, it is not easy for him to make the idea becoming real because there are a lot of country, especially developing countries where they only consider growth of economics without thinking of its drawbacks.


HOWEVER,
To Shai:
I am not sure about your economic calculation about electron energy and gasoline energy??? Why is electron energy cheaper than gasoline energy?
If we know energy resources and energy source and the ENERGY LAW of "CONVERSION" and "CONSERVATION" mentioned above and further, we know there are still a lot of electron energy source kept running by gasoline resource, I think your calculation may be wrong.
Moreover, gasoline is not a green power :))

Think over with wind turbines that could be the best choice for green power and that can be power source for your recharging station.

Shai,
I have just read an article about your new project in nrg, and there was some point missing.
I understand that you have 2 targets: peace in the middle east and Global Warming.
These 2 targets are very well connected.
Once we reduce our dependency in oil, the funding of global terror will decrease. Everybody knows that.
I just hope that our independence in oil will arrive before the oil terror will reach it's goal.
I wish you all the best in your new adventures and I'm inspired of every move you do :)
Yair.

Hi Shai,

I think your new project(s) could benefit so much - in a sustainable as well as an economical way - from the (free to use) revolutionary design concepts of Braungart & McDonough:

Keep doing the good stuff you are doing right now!

Thanks,

Dear Shy,
Actually I'm fantasizing on your idea from the moment I heard about it at the first time, I'm an executive manager at a bank in Israel and I fall in love at that start up idea. I'm willing to do any job at that start up.
I'll be happy if I will have a chance to talk about it with you or with any of your repetitive in Israel.
Best regards,
Gil

Not Important

"are they going to sell the energy or the cells?" I actually can't answer this question. Although I suspect their plan is to sell the cell array to someone who in turn will sell just the charging services. Clealy the intent is to remove the batteries and replace them with charged ones so the ecomonics would dictate selling just the energy and factoring in battery depreciation in the charging price. The implementation of which I was referring is being worked on by one of the cell manufacturers I used to do business with. They are a manufacturer not a service provider. The engineer I spoke with is not informed on his companies business strategy so I'm guessing on what their business model might be. He's just an mechanical engineer working in that area. That being said I did speak with him again last night and there are two version of this thing floating around. One is what I described earlier "a belt style array of cylinderical cells; The other something I was just told about that is something more exotic but apparently is showing more promise (because of packing density). This is being called a "stacker". Cyclinderical cells side by side have a lot of empty space between them and flat stacks don't. The flat cell stacker approach is comprised of one or more "hoppers" that are elevator controlled. The battery geometry in this model is apprarently composed of plat panel style cells arranged in one or more stacks. The top of a series of stacks is always level and is generally arranged in 8 stack row with an elevating motor on the bottom of each stack. There is a feeder arm that can pull in a new row across the top or push out the top row very much live some vending machines. The elevating motors then moves up or down depending upon if the flat battery packs (composed of several lithium Ion cells each) are being loaded or removed from the top row. Now what market are they targeting you might ask.. the cell array which was described to me is attached to a electic motor and dynamometer. All my friend knows is that the motor is a 3-phase, 4-pole 248hp electric motor. You'll have to draw your own conclusions from this. That's not the rarest motors in the world but its one I would pick if I were moving something around 2600lbs and wanted reasonable acceleration and range. Apparently, none of this is any big secret its not a research project at all. It was specificially requested by one or more clients who already agreed upon the stack geometry and capacity.

Mr. Agassi,

I have a solution to your problem of getting the major makers to build EV's and support your battery standards. I call it the "Open Source" automobile. That's right - think LINUX. I would like to explain it to you and how it would be feasible within your limited budget. Please kick me an email if you have an interest. I share your dream - see my Electric Vehicle blog.

Ariella

Mr. Agassi,

Congratulations and mazal tov for your extraordinary project. A car operated inexpensively and affords freedom from the Jihadists' oil - just tell me where and when to show up with my checkbook.

I wish you and best and most success.

Shai,

A blog is not usually the best place for me to contact someone for business reasons however, this may be the best spot to contact you.

I would like to talk to you about our lithium vehicles and the possible technology transfer or joint ventures that may be possible from our company to your project.

We have been developing and now selling through Wal-mart (Sams club) all lithium high speed consumer vehicles. I feel if more companies in this area worked together we could break though the barriers faster.

I look forward to hearing from you, and I hope that this was not to forward of me.

Warmest,

Looking to end the middle east conflict, oil dependency and terrorism? Oil is not the real reason for the global conflict but the illusory reason for it, the 1% reason for it, the 'scapegoat.'

Want to make the world a Better Place (like, hmmm, Gan Eden), want to achieve and accomplish a real Climate Change? THIS has to take place amongst us human beings, in our Minds and in Mind over Matter, us People, not machines, not robots and engines and batteries, nothing manmade but People, each one of whom is created to echo and reflect the Image of Wholeness (not religious "holiness") of our Creator and Maker.

The real reason and cause for all conflicts in the world is our metaphysical imbalance, our detachment from the universal Force of Life and Light in the cosmos and from one another and lack of sharing and caring amongst the Peoples of the world. Shai, if 31% of Israel's children live in or below the 'accepted' official (!) poverty line as is reported, why not fix this? All other countries are in the same boat neglecting those in need, only catering to the wealthy as in Golden Calf worshipping and idol worshipping.

Kabbalah, our ancient-as-in-timeless wisdom for all Humanity of how to self-transform our inner force and energy guarantees that when each one of us begins to behave in a God -like manner toward all others, care and share unconditionally to remove all lack, and all hatred and 'hamas' is eliminated from out midst, our precious globe will be returned to its original state of perfection and balance.

It is a celestial, a cosmic self-fulfilling Prophecy.
