I wonder if the original commercial product was canned over H+S worries...
must be fun if someone got stuck in the rollers, or chocks came loose, or
something in the mechanism fouled up. Not something a DIYer has to worry
about (well they do, but if something screws up it's their own fault) but
I could see it having some commercial issues...

I like the 'build one' aspect - but where does one source a big-ish
alternator these days? Make one? (i.e. same sort of DIY disk alternator
that some of the wind tubine homebrewers are cooking up) - or is there a
good source somewhere for alternators without any kind of engine to drive
them?

A basic car alternator can produce 110v.
