So I pick up this Harvard Business Review for an airport read and there is this interesting article:
http://hbr.org/2009/11/how-to-jump-star ... onomy/ar/1
A main point is that if we are ever going to advance with clean energy, we have to think of entire systems and not just bolting something onto an existing thing and calling it an environmental advance.
An example cited was a company called Better Place. I think a reasonable and brief summary would be this.This guy wants to help push electric vehicles. He is thinking about it. One problem is the battery. It cost a lot. The current cars are marketed with a 10 year warranty. To have a 10 year life, for reasons which I do not understand the battery can only be drained 50% before recharging. So he started thinking about separating the battery from the car. They developed a battery pack that could be changed in two minutes. Then Bill Clinton asked if they could not make the price so low that it would be a barrier to entry for others. He asked if they could make the car free. That led to the cell phone business model where the equipment is free and the fees are for the service. Our hero then began to think of the idea as selling 'miles driven' as a cell phone company charges for minutes used. The idea has been tweeked with stuff like recharging batteries at night so the utility can balance their load. He needed a demo market for this approach. He found the perfect one. The average person only drives 20 miles a day. It was small enough and populated enough that there would be a lot of customers in a small area, making infrastructure easier to build and cheaper per person. The government there was progressive and very interested in doing anything to reduce the potential for oil to be used as an economic weapon. Also, almost the only time a vehicle leaves the place is when it is stolen. And that place is - Israel. He has won government and some large company backing. They are now building the infrastructure for re-charging across the country.
How is this for thinking outside the box, moi?
Thank You
What can I say,
Great minds work alike.
Now if they would just interface the personal vehicle to work on a light rail infrastructure as well as roads, for speedier and lower energy commutes without the need to travel in a public carriage.
Let me know when "they" catch up to Moi's great mind on this next step.
Best Wishes & Thank You
Moi
PS Although people may indeed travel an average of some few miles a day, the idea is to have a vehicle and infrastructure fit for cross country driving as required from time to time.

The car companies are already talking about this, although it's way to early for details to go public. Another company is working on a robotic system that would extract the battery and load a fresh one. These suckers are big and heavy, as a previous writer indicated, and requiring manual handling of them is asking for trouble (lawsuits and personal injury, etc).
There are no barriers to standardizing the battery pack. This would entail standardizing its physical dimensions, connector placement and conductor functional assignment (polarity etc.) and the output DC voltage. These will all be smart batteries so there's some sort of bidirectional serial data interface also. Inside, the developers are free to use any kind of battery technology and organization they want, no restrictions.
You can calculate the required charging time / charging current (reciprocal relationship). Estimate the energy required to push a car 40, 50, 100 miles (whatever you think a minimum battery-pack range should be) at speed XX mph, multiply by an efficiency-loss factor (battery to controller, controller to motors, motors to forward motion, ...), translate that energy to joules or kilowatt-hours, then it's a simple calculation to estimate charging time for a given voltage and amperes of charge current.
These batteries will probably choose a standard voltage of several hundred volts, which could be charged at a couple of hundred amperes, if there's local power storage where the batteries are. They are working on quick-charging battery technologies but the local storage requirements are immense (or you need a direct high-voltage connection to the power grid!).
Interesting engineering problems all around.
Quality of the battery you get in exchange is obviously an issue, but view it perhaps like you're "renting" the battery pack and you swap it out every few weeks, or multiple times on a long trip. The processor in the battery pack will track how many times it's been charged & discharged, so will estimate with reasonable accuracy how much storage capacity it has and how much further lifetime can be expected from it. You're really buying the energy in the battery, not the battery itself.

I'll make my usual objections to pure electric cars here. At -20F batteries lose so much capacity they are almost useless; not to even mention the huge electricity demands of heating and defrosting equipment required to operate a car. Inmid winter, now for instance, lights and wipers must be operated by electricity nearly all the time. My best guess is that by the time you leave your driveway the battery will need recharging. --FLO--

The problem is a nation wide brand new system of delivery would cost a lot of money

I don't think that will make much difference one way or the other, our electric grid is so outdated and over used it needs to be redone no matter what we do.
Not much has been spent on infrastructure in this country in the last 30 years, and it shows.

How about an area where, ideas can be dropped like pearls.
Ideas that should make someone rich or do it better.
Okay, here is my first.
The government should establish a standard battery dimension and connectors for electric automobiles.

Moi
please drop pearls on this thread
Well, I didn't even get past "
" to read any further.
"THE GOVERNMENT SHOULD..............."
Everybody is moaning and groaning about how much THE GOVERNMENT is sticking its nose into everything and how our freedoms are being over run etc. etc.
WHY should the government do it?
It IS possible for business to establish standards, in spite of the desire to be unique for a competitive edge.
Sometimes business has to battle it out, like Betamax and VHS, or Blu-Ray and whatever lost out to Blu-Ray.
Sometimes business doesn't have to battle out a standard in the market place. It takes awhile and a lot of negotiating but Industry wide standards are created and agreeded upon in ISO. http://www.iso.org/iso/about
Standards will of course always be in a state of development so we will have to live with old standards for awhile as new standards are developed and adopted.
What standard can you think of that is INTERNATIONAL everywhere.
The government's role in American society is so all encompassing now. And this coming from a liberal. The conservatives have been so busy developing laws telling us what we can't do I have just begun to feel stiffled by and tired of government meddling in many areas where it just seems the government should not be involved.

That's simple.
The government should do it to keep some DUNDERHEAD from coming up with a scheme to make TONS of money by exploiting the consumer...
...fuck this consumer beware bullshit ... let us make it unethical bastards beware!

Just a note -
There are extensive and detailed international standards in electrical engineering, especially for data communication. That's why the internet operates globally, as well as telephone calls. There's a branch of the UN, the International Telecommunications Union, headquartered in Geneva, that sets these standards, with input from member nations. The UN may be ineffective in international politics, but it can be highly effective with non-political subjects.

Was that just a note or do you personally support size and terminal standards for car batteries so as to allow cross country travel by simply exchanging battery packs at the service station instead of waiting hours to charge up a built in battery.
For a moment I thought I saw a blue aura around the note above.
