Currently browsing the 1950s Popular Sciences, ran across this:http://books.google.com/books?id=Iy0DAAAAMBAJ&lpg=PP1&pg=RA1-PA278#v=onepage&q&f=true
You'll have to scroll down a little to see it, it's the bottom right corner of page 278, the page the link above *should* take you to.
Just thought it was interesting....
On a side note, my addiction to reading PopSci and PopMech back issues over the last couple of years has led to a "projects I wannna do" clipping/notes set that is essentially impossible to ever, ever Ever EVER complete (barring science-fiction-grade life extension discoveries).
Which is a good thing.
