Toyota looks to next-generation hybrids

As I have mentioned before, and as I will tell anyone who even looks remotely interested, I love my Prius. I've never been much of a car nut really, and my automotive skills are sadly lacking (ever hear of the time I killed a BMW by pouring cold water on a hot engine block?), but I am deeply enamored of what is essentially a big computerized geeky toy. So I came across this article which peaked my interest today:

The Prius was a big step forward for the future of green cars. Up next for Toyota and its rivals: Far more powerful batteries for next-generation hybrids, plug-in electric cars and eventually zero-emission fuel-cell vehicles powered by hydrogen, which combines with oxygen in the air to form water... Toyota showed a "concept" plug-in Prius made of carbon fiber reinforced plastic that's about a third of the weight of the current Prius and doubles mileage... The third-generation Prius could include a new lithium-ion battery more advanced than the current nickel-metal hydride battery, allowing more power to be packed into a smaller battery...

Drool. Now give me a hybrid minivan packed with the features of the new Caravan, and I'm definitely grabbing that up...
