That's definitely FUD, the battery has never cost that much on a hybrid - closer to $5000 back in the early days before they were making money selling them, and now it's closer to $2000 for a new battery - a rebuilt/used one would be much cheaper still. The other thing is we still don't know how long the batteries will last - they are treated like royalty by the car's computer (never discharged less than 40% capacity, etc) and so far there haven't been mass failures, so we're probably looking at 15 years or more.

This is untrue as well, first of all if it gets in an accident there are deceleration sensors that disconnect the battery from the rest of the car before damage can occur to the car, so there's no electrical danger even if you have to cut the car in half to get someone out... This is one of the reasons they're expensive, lots of little gizmos and tons of testing to ensure safety. Second - the battery itself is MUCH safer than a normal flooded lead-acid car battery that vents out explosive hydrogen - NiMH doesn't vent any gas and isn't a danger to people when ruptured, plus they put it in a very safe place in the car, typically they can be recovered undamaged from very otherwise totalled cars

Maybe an electric engine is less than a Deli head (although I'd like to see the facts behind that statement because it seems a little far fetched based on the price of electric cars today

), but an $8000 battery sure isn't.
In an electric car you're looking at a $5000 - $40,000 battery depending on chemistry, capacity and other features, and that IS the main expense on an electric car, but right now there's no real mass production - NiMH patents are held by the oil industry and they won't license for production in anything other than hybrids now, so really they have to use Lithium Ion, which will take a while to drop in price since there's no mass production of units for EV's at this time.

We're talking like it's a toy electric car that you can put on your workbench and tinker with. But it's something that will move and protect your family - air bags, abs, luxury items, and all the other stuff that goes into cars today. Plus the extra stuff that would go in with electric car technology. There may be less engine parts for maintenance, but there are other parts (not in gas cars) that will need caring for. I just think the "alot less maintenance" statement is a bit of wishful thinking.
It's not - really! You're right, it won't be stuff you can just tinker with (well, some will) but the reliability of the electric drivetrain is amazing, even in a hybrid, which still has a gasoline engine vibrating, heating, stopping and starting, etc... No clutch, no torque converter/transmission, no gears (or just two in some cases)... I think you have to experience it.

It may have less moving parts than a gas engine (I don't know enough about either to make that statement). But does that necessarily make it simpler? I feel safer tinkering with a Delica engine rather than an electric engine that could kill me if I touch / cut / accidentally pierce the wrong part.
Really, electric motors CANNOT kill you if they're not hooked up to power, which would never be the case if you were working on one... I've worked on lots of electric motors as a furnace tech, and the first thing you do is make sure there's no power to whatever you're working on... I guess it would be a little frightening "working on" a motor that you really had no knowledge about whatsoever, but really once you learn a bit about them it's not so bad, and WAY simpler with 1 or 2 moving parts.

Everything has a price, and usually a negative consequence. Just look at wind power "clean and free" OK, until you see vast swaths of land covered with these great windmills and masses of dead birds and bats at their bases. When they first came up with gas cars everyone was excited 'cause "they're clean - no more horse shit!" and we all know where that lead... I hope to see solar panels on roofs and mechanisms that will charge batteries when going downhill and the like, but have no illusions that we will ever have the freedom to travel as far and fast as we currently enjoy without further decimating the world's ecosystems. Me thinks we best get used to walking...

Around here we have lots of excess hydro power at night (during the day we sell it to the US, that's why we "need" more generating capacity) and since that's when most commuter EV's would recharge it works out quite nice. The other thing that can, and I expect will happen is as new technology is invented to power electrical devices they can be incorporated and retrofit into EVs... Right now billions of dollars are being sunk into hydrogen fuel cells, which is just another way to generate electricity (although very inefficiently when the whole cycle is considered) but others with much less funding are working on devices that draw energy from the environment to produce electric power and as these technologies mature they can power EVs, unlike gas/diesel which is really restricted to a few liquid forms of energy that can possibly power them in the future. The flexibility of an EV allows it to be powered by today's conventional technology (diesel/gas "generators", ie hybrids), batteries, capacitors, etc. plus tomorrow's technology!
