It's great to read that Ames Research Center will be making progress in Aviation especially in reducing the impact on the earth for travel in the air.

"Green Aviation"? That's a contradiction in terms, unless your airplanes travel at such low speeds that you're willing to lose 95% of your business. Physics cannot be denied. Streamlining helps, but slicing through the air at the high speeds people have come to expect will always take a lot of power, no matter how much you streamline.
The only hope for making it green is to get all your fuel from clean energy sources. This can be done economically using advanced nuclear (i.e., molten salt) reactors to synthesize hydrocarbons from air and water. So the straightest line to green aviation is through the Nuclear Regulatory Commission. Get the NRC to bring its regulations out of the 20th century and into the 21st.

What a puff piece! Did anyone at the Voice contact a non NASA paid "expert"?

"Madavan" is pushing his personal research funding agenda. Batteries have no where near the energy density to complete with a plane the likes the venerable Boeing 737, and he knows it.
