I know it's great that engine efficiency is getting better, but this is still working using old, crude principles. Combustion engines are the equivalent of analog in computing and engine makers still need to reach their digital "Eureka!" moment. The gas turbine is [226 years old][0]! Computing on the other hand has seen significant change from [Charle Babbabe's mechanical computer][1], to vacuum tubes, transistors and (hopefully within the next 50 years) quantum computers. Hopefully with progress in batteries and clean energy generation, we'll see the death of the great polluters before the end of the century. We can (and should) do better.
