Your right about the gov R&D $...it would take forever....I imagine that would put USSE way behind, if it had to wait for that kind of funding...
now, if the gov wants to hand back some of the R&D $ spent...hell , take all you can get.
Just dont wait for it....
If the Gov wants to 'fund' the automotive fuel portion of the year 3 project, again, sure, take it.
