as the boiler would be something about the size of a coffee can at the focus of a parabolic reflector.

Hmmnn, Interesting indeed. Well be careful and keep me informed (offline if necessary as this isn’t really rotary related… yet). I assume that this parabolic reflector would be for sunlight, meaning this would be located outside. If successful, I doubt you could generate much pressure, but just in case you should be aware that when water turns to steam it increases 1600 times in volume, so if your vessel bursts under even moderate pressure (<~10psi) it will flash off and immediately displace air so in an enclosed space would leave you in an extremely hot O2 deficient atmosphere… not ideal for sustaining life.

Here’s a link for some calculators. http://www.engineeringtoolbox.com/steam-condensate-properties-t_28.html. May be of some use to you.
