This sounds awesome. However I'm a bit saddened that there is no mention of CO2 or climate change in this discussion. What about building solar planes vs just faster planes will do even more harm to the environment if people start flying more because time is now shorter?

Just think how much C02 you'd produce if you took a ship across the ocean for days on end....
