      What is water vapor? A greenhouse gas (though a milder one than CO2). What does an even more water saturated atmosphere cause? More storms. In fact, the gas released will also cause an increase in air temperature (you can argue the same of fossil fuel burning). So, dumping into the atmosphere will mean a milder form of the global warming trend.

      What about dumping it on the pavement? Beyond the fact that'll quick create lakes, it'll also ruin the environment (like cities) by flooding the place. Cities might have reservoirs to catch the waste, but they're the place with the least natural environment to lose to oversaturation.

      Okay, what about storing it? That's a horrible idea. The more fuel you use, the heavier the car is. That means that the reverse of normal cars occurs (ie, the lighter empty tank makes the car more efficient). A few gallons of water, over the long term, is an efficiency loss. It's also a hassle to have to drain the car every time you fill the car up. The big plus, though, is that such a system offers a pretty reasonable recyclable source of water.

I don't think any efficient (assuming that externalities aren't taken into consideration) power source (strictly speaking, hydrogen is a power store, but it's the chief usable component being discussed) will have zero or even minute consequences when there are millions to billions of humans using said power source/store. As such, it is wise to either consider the possible consequences of a power source/store and be prepared to live with them, think of a new power source/store without the problems (like I said, I don't think it's possible, but I'd love to be proven wrong), or possibly internalize the consequences of the power source/store so that the accumulated side effects is minimized.

      I've yet to hear of a mechanism, short of government, to aim towards the goal of internalization. Since I'm pro-small government, I'm edged towards the first option, since hydrogen/water based power store is one of the safest I can imagine. If a mechanism can be devised to achieve the third option without government, I'm all ears, as such a system would likely lead to the use of hydrogen or a comparable power store, being the most efficient known (taking into consideration externalities).

      What makes you think that high voltage will help significantly? (Significantly as in "double the range").

      Okay, a quick lesson on electricity...

      Energy is measured in WATTS. The ammount of work you can do is the wattage you can get.

      Since wattage is a combination of voltage and amperage, increasing the voltage will increase the wattage. Doubling the voltage will double the wattage.

      If you want to verify this, just take a look at the specs on your computer's power supply. At 240volts, your power supply will draw only half the current as it would if running at 120volts. This is clearly listed in the specs for all power supplies.

      The other important thing you need to know, is that voltage is never consumed. Voltage is essentially a constant... It is current that is consumed when you do work with electricity.

      The easiest way to prove the point is to use an international voltage converter. If you run a 100watt lightbulb on 120volts, it will use almost an AMP. If you, instead, run from 240volts, through an adapter, you'll see that it's drawing less than HALF an amp from the 240v outlet.

      The only other thing you have to do to verify that I'm correct is to see what batteries an electric car is using (probably quite large, 12v deep cycle batteries) and find batteries that are half the size, at the same voltage, and as close to the same current as possible. I'm sure it's possible to make them, because that's just how batteries work... You can reduce the size, and you'll also reduce the current/AMPs accordingly, but you don't have to reduce the voltage any. Just look at the different sizes of car batteries, or even the different household batteries. They are all different sizes (AAA, AA, C, D) and their current will vary accordingly, but the voltage remains constant, because they use the same chemical compositions.

      If I didn't make the point clear, just let me know what part of this is misunderstood.

      Batteries just don't store enough energy.

      You have no idea how batteries work, nor how general electronics works, so how can you so confidently make any such claim?

      Obviously, lead acid batteries are an option, as cars with lead acid batteries are already getting over 100 miles per charge. With a better design, that utilizes much higher voltages, you can increase that range immensely with very little change to the design.

      The charger in use will have to be modified of course, but more importantly, you either need an electric motor that can handle the increased voltage, or a DC/DC converter that will drop the voltage to a level the motor can handle.

      If you change the motor to one that operates on double the voltage, it will require half the current.

      If you add a DC/DC converter, you'll get the same voltage from the new batteries, but double the current from droping the voltage.

      You can't use their actions as proof of lack of a market. I don't know Ford's story well, but I do know plenty about the EV1.

      No, I'm well aware of them. I believe there is a huge market for electric vehicles if you can get over a 100 mile range... That would take care of all the suburban commuters, and even the majority of rural users.

      If you want to talk about economics, look at how successful hybrids have been, even though they aren't too much lower in fuel consumption, have much higher retail prices, and need more expensive maintenance. A fully electric car would have none of the disadvantages, and since GM has already shown a practical, fully-electric vehicle with a pricetag of around $20,000, the economics appear to be there.

      The demand for electric "city cars" is where I see a serious limitation of demand.
