I think electromobiles are a perfect application for hydrogen fuel cells. Lithium, which is used for high-density batteries, is too scarce to use it in the large batteries cars need (and it is used anyway - way to get rid of resource-dependency...), and have the problem of requiring charging, which takes time. Hydrogen fuel cells, while their efficiency is somewhat lower, can be refilled at stations like combustion engines can, but their fuel can be generated without significant depletion of resources if you have a source of energy for that, enabling extension of their range with fuel stations similar to conventional vehicles, a solution I would certainly prefer over lithium batteries, despite potentially higher cost and space requirements.
...and the dangers in transporting, storing and using it. Plus to get hydrogen, you need to split water, which is a huge waste of energy.
That may be but in terms of practicality for transport its a lot more practical than batteries. Batteries take too long to charge and are way too expensive. Yes Hydrogen is dangerous but if we can figure out the logistics and get an infrastructure in place there's no reason it can't become the basis for our fuel. Yes its hard to get at but so's Oil when you think about it. How much money do we spend each year finding reserves, building platforms etc? How much energy does THAT use?

o joy those sweet cards that take 6 hours to charge and run for 3 hours at 30mph
If you knew what you are talking about, you'd know that most fully electric card manage more than 100 miles at usual driving speeds. Also the charging time is irrelevant, as all you need to do is them into a regular outlet when you're not using them. The cost of charging an electric car is usually a lot less than the cost of the equivalent amount of gasoline/petrol, even in the US where your gas is a lot cheaper than here.
The only thing stopping electric cars from being a mass success is the propaganda being spread by oil companies about how crap they are, when really, for regular town drivers they are better.
