What are the two of the most glaring problems in modern aircraft? Noise and
Totally uninformed author feeding horse manure to the mushrooms. The aviation industry and our gov. are in total denial to the reality of commercial aviation. The most glaring problems for aviation is:
1. Increasing cost and declining availability of jet fuels.
2. Lack of any cost efficient replacement for commercial jet fuel.
Biofuels are dependent on NPK fertilizers. "P"hosphate in NPK will peak in less than 30 years and based on current population and will be gone in 50-100 years. That's not accounting for an additional 3-5 billion expected population growth in that time period. Ninety five percent of human food production is dependent on NPK fertilizers. There is no known substitute for phosphate. It is those same food crops with which biofuels (especially algae) compete head on. Do we really want to decrease our technical window of opportunity to solve our energy problems - by turning our food fertilizers into fuels for jet travel?
Commercial aviation is totally screwed if we can't come up with light wt. electric power systems - as we have in micro-drone aircraft. That means really powerful, high capacity and very light wt. electrical storage devices.
Military aviation will take all the NPK fertilizer they want to make fuels from biofuels (and or human lipids) based on" national security" needs as they see them.
