"The term "hybrid" refers in this case to the engine - it can run on either diesel or vegetable oil".That's what hybrid means? That makes the engine dual fuel, the Welsh have being doing for years in their diesel cars. One could tell from the malodour of the exhausts. And I suppose there might be dual fuel dragons (coal and oil) too.The fact that the driving force is an electric motor and it doesn't matter whether the electricity comes from mains charged batteries, on-board diesel chargers or whatever, is the hybrid part.Probably the resulting environmental benefits could be achieved by lightening the existing single deckers by removing all the seats, replacing them with perches, grabrails, and straphangers.The livery is irrelevant. As a passenger I don't care what the method of propulsion of the bus is or how efficient it is in terms of operating cost, thermal efficiency, or environmental benefit.We will probably find that the first year of savings is wiped out because of the application of the livery and subsequent years by the additional cost and energy involved in building the bus in the first place.
