A mind-bogglingly stupid article in the Times came my way. Someone has built a small aeroplane powered by batteries. So far nothing exciting. But then to report the claim Ms Lavrand said that the fuel cost per hour of the Electra was €1 (70p) compared with about €60 for an equivalent petrol-driven machine. The motor and batteries will cost between €10,000 and €15,000, about the same as existing small petrol engines. I don’t believe that a 25 hp engine would be anything like €10,000, nor that the fuel price disparity could be a factor of 60 – it should be the same as for electric/petrol cars; ie, not very much.
Rather more sanely, Hot Topic points to a report saying that NZ “causes” about 10% of its CO2 emissions from long-haul flights. I say “causes” because its not really obvious who to count the emissions against – NZ for being such a nice place that people want to come, or the home country of the people that go. Plane CO2 is the hardest to reduce (electric planes are obviously hopeless) and NZ is a long way away, so this may become a problem for them, in the unlikely event of peoples conciences getting the better of them.
