super man ? +5

Duct tape...... Actually it's battery technology.

Super glue, I don't play with toys because I drive a 400hp Vortech supercharged Camaro SS!

electricity?

The cost, the Volt is going to cost nearly 50K http://www.futurepundit.com/archives/005119.html http://www.cleveland.com/business/index.ssf/2009/08/post_35.html

the logic of an electric car taking money when they have a free energy stick man.

Special interest groups, I'm sure!

Battery tech nology has been a huge obsticale getting in the way for many years. The manufacturers seem to have made great advances of late and that is why we are hearing more about the electric car being a reality. we have to remember that the oil companies had a large influence on many industries that would cut into their bussiness.....

Battery technology. All the batteries we have are too heavy, too expensive, don't hold enough charge, and take too long to charge up. They have got better, but to be really competitive, they have to improve by a factor of about four across all these aspects.

A baby....they can,you know ;)

Battery technology. Chevron has the patents for large-format NiMH batteries like that used in the old Rav4EV, so you know that NiMH-powered EVs are not going to happen EVER again. Lithium-ion packs are expensive as hell, so you know they won't be commercially viable for a long time. Lead-acid has poor energy for it's size/weight so they really aren't good for anything that needs to go much over 30-40 miles. And then there are the infrastructure issues. How many charging stations are there? While the truth of the matter is that most people only drive short enough distances that they could go all day on a single charge and plug their car in at home while they sleep, people would rather just worry about a 5-minute fill-up every week or so. And long trips are right out too since it's rare to find someplace away from home to plug in anyways. Not to mention all of the misconceptions about EVs that keep them from being commercially viable. Like diesels, they are thought to be slow despite the fact that many of them are not only capable of breaking the speed limit but also can out-accelerate most gas-powered sports cars. And they are all tiny too.... even the EV-converted Explorers and F-250s. As long as people equate EVs with golf-carts, nobody will want one. And as long as nobody is buying, there is no economy-of-scale to drive down production costs and therefore prices so many of the people who do want one won't be able to afford them. Oddly, about a century ago MOST cars were electric :P
