Why isn't this a good design?

Being as I am reasonably literate I was able to read the title of your post and, subsequently the body text thereof, as: "Someone must have thought of this before, but apparently rejected the idea. "The" electric car problem is the insane recharge time. So, don't recharge. Swap batteries, and let the ones you're not using recharge. And build "swap stations" around the country where you pay to swap in new batteries. And have them swapped automatically - push them in on one end, the old ones come out at the other. But they're not doing this, so something must be wrong with the idea." I responded to be helpful with links to sites that had more information on this idea; specifically to the first part of the first sentence, to wit: "Someone must have thought of this before". They have, hence the links. The fact that they may or may not have rejected the ideas, for whatever reasons, are not germane to my post. Jeez: you can't help some people (and I wish I hadn't bothered - if you were standing in front of me I'd tell you were to stick yourself and, yes, I am annoyed with you for no real reason that I can currently think of other than you are being bloody minded).

No: bloody hay fever is driving em nuts: just want to scratch my eyes out. Hope I didn't offend you. Too much. :-)

Would I be in back room if I were easily offended? Ok maybe I would be, plenty of people are.. Hay fever is teh suck, I don't even have it that much but I sneeze all the time now, it's worse outside so at least I have a reason not to go there Winter FTW!

We're getting there[^].
Proud to have finally moved to the A-Ark. Which one are you in?

Some are nice.. but the Mini E and the BEV electron? Insane recharge times. or the Tango? Impressive stats (except range), but with a design like that..
Hey, like I said... We're GETTING THERE... We're not there yet :)

That could work, there would have to be a lot more of those than of swap stations though.. How would they charge you for the electricity?

Noting fancy or expensive; for the residential areas a designated parking spot with a key for the outlet or even an electric switch inside your apartment or outlet programed to “serve” only your car. For the public areas, booths where you slap your credit card and enter the spot number. The problem as you mentioned it will be the recharge time – if you forgot to plug your car in the evening you will not be able to commute on the next day. But they could make the cars “smart”. There will be a lot of “free” money because of removing from the vehicle of the most expensive parts – the engine, pumps, complicated gear box etc. part of this money could be invested in the car computer: it will give you a call if you forgot to plug it in, if you not answer for some time, calling your boss explaining that you’re a nub and will not be able to go to work on the next morning and eventually electronically sign your resignation. Things like that.

Just like you take your empty gas bottles for a refill. Simple yet elegant solution.
Two heads are better than one.
The gas bottle weight is not 200 Kg/400 lb. and it not costs > $4K.

There are many, many reasons that this would not be practicable. Apart from those already mentioned Cost of real estate to build a large enough facility in highly populated areas would push the price way higher than many people could afford. What do you do if you arrive at the swap station just after they have sold the last charged battery pack, with insufficient charge left to get to the next one? You cannot jog there with a spare can for a few volts. With current technology, battery powered electric vehicles really are a dead end. Only when fuel cells are improved enough will the practical electric vehicle start to be seen.

Oh, but it does. Honda has a Hydrogen powered fuel cell vehicle that it sells only in (I think) California USA, at the moment. Clickety[^] The problem is getting sufficient quantities of Hydrogen, at a reasonable cost, for it to become a feasible mainstream product. Many companies have developed fuel cells to power Lap-Tops (most that I have seen powered by Methane) just one example[^].

This is dead end as well. The only efficient way to extract free hydrogen is from Methanol – so again fossil fuels. I would put my bet on the nuclear power plants plus electrical public transportation. IMO this formula is perfect for the EU, not sure for the US though.

Last time I read about it, they still had huge problems with hydrogen leaking from the storage units, has that improved? As to getting the hydrogen, electrolyzing the sea is easy enough, not cheapest way now maybe but that may change

Not only expensive but if you are using energy from a regular power plants for the electrolysis the pollution and CO emissions will be far more than if you just use the gasoline in your car.

As Deyan has said, the monetary and environmental cost of liberating Hydrogen from water is currently so high that using Petrol is probably still better. I have not seen anything about storage problems but then again I haven't been looking. :)

Yes – if we are able to use a green energy for the electrolysis this would be a game changer.

There are one or two other methods under development using Ammonium Borate (I think, without looking it up) some variants of which can be recycled. Also some of the Metal Hydrides look promising. As concentrated research into this field is relatively new I think it is too early to call it a dead end to the same extent as storage batteries.

I would partly agree. Only partly, not from a technological point of view but because of enormous opposition to Nuclear Power generation and the problems of getting people to give up the 'freedom' of personal transport. I don't care because I have my Jet Pack and Hover Board but others seem to.

Absotively! That or a truly efficient, on a par with Photo-synthesis, photo-electrics.
