Some discussions on the performance that might be practically achieved
with different designs may be a useful start - as long as it's done in
the context of a practical unit that could actually get built, rather
than just a theoretical wish list.

It would also be good to have some idea of the cost of any special
parts like cells too. Without that info, it's hard to know how
practical particular designs would be. 

Looking at export/technology controls might be useful early on too,
since we're going for high performance.

I've often wondered how a 21st century version of a 5065 would
perform, so it's great to see that I'm not completely alone in my
