If it would work, someone would have done it, with the cost not being an
object. The weight issue is too much to overcome, along with the
complexity. Still, the whole thing comes back around to the fact that it
demands more energy than is available.

Give it up. I know you won't; you just want to tilt at windmills. That's
OK, if that is your thing. It is not mine.



This is nonsense of the highest degree.

Everything that has ever been done has been done a first time.

In the piston world, no one is going to throw a lot of money at this unless
they think they can do it cheaply. Otherwise, they are wasting their money.
So to say that someone would have done it regradless of cost seems wrong to
me. The market potential is pretty small, so unless something is obvious,
it won't get done for profit. It will get done by someone who wants to know
how, why, or what if.

If you know how a jet can do it, then all you have to do is find out how
much you have to lighten the system, and how much energy you need to add to
the system.

You are helping by pointing out the problems that need solving, but not by
saying they are unsolvable.
