Message: Re: Can lithium-ion batteries power an airplane? NASA's answer: Yes, indeed!

Yes !  Just as soon as the new solid state cells have twice the energy density compared to what is being produced today.  Yes!  Just as soon as the new solid state cells weigh half as much an currently produced cells.  Yes !  Just as soon as the new solid state cells are manufactured at half the cost of the currently produced cells.

When will that be ??  I don't have a crystal ball.....
