In a previous thread (and maybe in this one, I'm afraid I might have missed spots) you mentioned that fuel cell buses still weren't practical. I saw recently that Philadelphia (and I'm sure other cities) is purchasing hybrid buses as a step in the right direction:
Philadelphia Hybrid Buses
Is anything like this in the works at WDW?
Currently, Fuel Cell technology for transit busses is far from mainstream. As it stands, the technology exists, but it's still very expensive, breaks often and easily, and needs much improvement before it can become practical.
The Fuel Cells themselves take up a LOT of space, and add a lot of weight to the bus. In addition, from what folks who have been in contact with these busses tell me, is that they often spend more time in the shop than on the road. I think as time goes by, and the technology improves, Fuel Cells should prove to be a viable alternate fuel.
Another alternative is currently being implemented with that SEPTA article you linked to, as well as on the Boston Silverline... Diesel-Electric hybrid engines. I'm eagerly awaiting reports on how these hybrids perform. While it is a relatively new technology, it's based on one solid rock, and one well developed technology, so I have strong faith that these new hybrid engines will do well.
It should also be noted that todays Diesel engines are about 80% cleaner than those you might have found just 5 years ago. With proper maintenance, Ultra-Low Sulfer Diesel fuel, and filters on the exhaust, these new diesel engines are actually cleaner than the "Green" CNG (Compressed Natural Gas) engines.
As for Disney... I know in the past we have tested alternate fuels. We are always looking to improve our operation. One of our head transportation honchos
