The need is for Bureau's of Weights and Measures to establish a standard vehicle battery unit per output and dimensions.

Storage would be left to minimal requirements with open ended considerations for advancements.

Allow MOI to drive his electric vehicle from LA to San Francisco, stopping and quickly exchanging Moi's power drained battery pack for a charged one plus a charge fee.

Even if THEY hide some battery components in door panels, a central exchangeable battery pack is the only way to beat the problem of range, fast charge and unhappiness over the prospect of purchasing a new battery after five or eight years.

Hi fhunter, I know you are going to ridicule this idea with your practicality. I can take it.

Recent evidence with Brain PET Scans as subject were imaged next to a cell phone turned off or

turned on and muted

demonstrated clear activity change in the regions of the brain closest to the radio frequency transmitter.

If you are willing to drive a PRIUS I hope you are willing to live under high power lines. There are some less expensive homes there. Good deal for you.

EMF is the smog of the 21st Century!

You heard it at EA first.

Ridicule what? Battery parts in door panels - yes. For the reasons of safety and convenience.

As for the changeable batteries, I am all for it.

It is doable, but requires much consideration, and some parts:

For the car and battery:

* Safe connectors able to sustain high currents, and frequent reconnections.

* Some kind of gas gauge, taking into account battery aging. You do not want to end up in the middle of nowhere, without energy? And getting the car moving would not be as simple as getting few liters of gasoline.

* Cheaper batteries. (As I have said in the post above - the price of new battery pack for the Tesla Roadster is quoted at 36000$.)

For the system of exchangeable batteries to work:

* Cheaper batteries. Or else the coverage of this system would be really limited.

* New power grid, so the batteries can be recharged fast enough.

* New battery chemistry, cause lithium batteries age even when unused.

Ok. Now I am going to ridicule Moi for comparing mobile phone and prius in levels of EMF.

First of all, electric motors do give, you know, slightly different frequencies of EMF, than a mobile phone. Like, 6-7 orders lower in frequency. That, and motor's EMF is mostly contained in the motor itself. So compare low frequency, low power EMF from electric motor, with 0.5W (or so) transmitter at 900Mhz from mobile phone. And if Prius is not made of fiberglass plastic, or something similar, it's body would shield the driver from EMF.

As we know from physics, air drag becomes the prevalent force even at speeds as low as 45-60km/h. Even more so at highway speeds. Power required to overcome air drag is proportional to cube of speed. So, raise the speed twice, required power raises 8 times. What was top speed of that car? 25mph? Now recalculate power requirements and batteries volume for engine power of some 30hp. It is not much, but let's consider that it is enough.

Now let's start with the batteries. Eddison alcaline batteries, are better know now as Nickel-Iron batteries. Yes they have long life. But on the other parameters they suck.

Energy efficiency? 60-80 percent. So on every kW hour you pump into battery, charging it, you get only 0.6-0.8kWh back.

Energy density? Only 30Wh/liter. Compare with 250-620Wh/liter for lithium batteries.

Self discharge? On par with NiMH - about 30% per month.

Oh, one more thing, from what I have found on the net, the demise of Baker cars was.... invention of electric starter .

PS. Tesla motors car looks interesting. But lithium batteries lose about half their capacity in 2 years. And a new battery pack for 36000$ ? Sorry, I'll buy something cheaper, and easier to service. Don't even start me on recharge times. May be in USA, outlets/wiring, which can supply 70A at 240V are common. Here, I even do not know where to charge such thing.

As with any new technology the initial price is high, then, prices come down.

My first micro-computer cost me $2,000.00 They are much, much cheaper today with improved performance, not to mention the Internet, which was not around when I bought my first computer.

Try googleing Nissan Leaf and Chevrolet Volt.

I think I will eventually go with the Leaf for city and short distance driving. We calculate the savings in gasoline alone will make the payments. Nissan Leaf costs around 20k in California right now.

And meet by 1994 4WD Ford Expedition.

You will be inside a well padded hockey puck if not a hydroplane on a minimally wet street.

Y'see what they use to call traction <good>,

they now call road resistance <bad>.

Moi

PLEASE, everyone else, buy one of those motorized hockey pucks.

over-sized tin can trucks with large hemi motor and plastic testicles and sac hanging from back trailer hitch so all know what you want.

Then, you, too can end up like moi with a LARGE PETERBILT up YOUR ASS, smashed flat as pancake and covered with REPUBLICAN HORSESHIT... make moi smell better, what about you?

moi, you don't want to save money, you want to send money to the Middle East and take PETERBILT up the ass...

moi make some Sutlan with LARGE PETERBILT berry happy and berry $RICH$ buying gas for 1994 4WD Ford Expedition road hog 4 gallons to a mile...

...all the while moi begging E.A. members to tell him how to make money on commodities market.

...what is WRONG with this picture?

...moi missing function in brain somewhere?
