ANNOUNCEMENTS There are handouts that you should pick up at the front. The first one is a fuel cell bus that you can assemble, just promise to throw the rest of the paper in a recycling box. The second is an article that describes the challenge beyond technology. It refers to how we live our lifestyle and how it effects our consumption of energy. The third handout is an article that addresses how to internalize externalities. Our guest speaker, Jamie Levin, works for AC Transit and is very into having hydrogen as an energy source. He might have to just talk to you about his program since we are having technical difficulties. LECTURE First of all, I am also an alumnus of UC Berkeley. I got a graduate degree in city planning, dealing with issues of land use and transportation energy. I am a user of AC Transit, I believe in it so I know what is like when it doesn’t show up. Even with the best technology, if its not reliable it’s very frustrating. Fuel cell buses are like oversized electric golf carts. The energy that it takes to run such a big bus is given by a big black box, the fuel cell. It does this through the use of hydrogen. Hydrogen is a plentiful resource, but it is not free, because it takes energy to make it. The fuel cell takes hydrogen and oxygen from the air and combines them in a chemical, non combustion reaction to generate electricity. It is highly effective. We only have three fuel cell buses at the moment. I’ll explain the direction we’re going. It is not only AC Transit that is using these buses; we have a partnership with Golden Gate Transit, who is using them as well. Most of you are aware of AC Transit; we serve the area in the east bay. We also function in other areas of the bay. We are one of 14 big operators out of a total 26 operators. We are confined to the west of the east bay hills, and we do a lot of things to promote transit ridership. A lot of you are using it through using your class pass. We now have nextbus.com predictions. There is also a PDA application to access nextbus.com to see when the next bus is going to come. Another feature you are going to see soon is the
