That said, Honda's huge initial outlay for prototypes is not surprising. It may be foolish to rule out initially difficult concepts because of apparent lack of practical feasibilty in the present.
I'd like to see other assessments from purely scientific bodies--or as free from politics as is possible.
The only thing that would satisfy the Left is a 'free energy' system. And, even then, they would find something environmentally objectionable with it. I don't pay much attention to the leftist 'solutions'. The burden of developing the future is on the Right side of the political system.
You're right about Honda's initial investment. I doubt that Honda has put out as much money as they have for the fun of it. They seem to think there is a feasable future in the technology.
