I have a nice, south-facing room.� The trouble is, my neighbor's
two-story house is about 10 feet away, due south.� Consequently,� if I
cut an aperture in my wall, the sun would find it only mid-summer.� The
rest of the time, my neighbor's roof would block the sun.� Demolishing
his second story is not an option, he says. I thought of using mirrors to relay the sun's rays down the canyon between our houses, much as a periscope would.� This could be an extension of John Carmichael's reflection sundial (#4 in his reply to Ronit)� Several problems with that, since the horizon-to -horizon and season-to-season arc of the sun would require either
Finally, I remembered Mike Shaw's clever implementation of an Indoor Dial he reported on October 29 (or thereabouts), 2000.� He used a 150 mm diameter, plastic sewer pipe to hold the fibers in an equatorial semicircle.� While he could have installed enough fibers to give 5-minute resolution, he chose to start with just 15-minute resolution.� The display ends of the fibers were arranged around the periphery of a clock face.� He reported that plenty of light gets down to the display. This isn't quite what I'm looking for, though, as I'd like the equivalent of a garden sundial in my room whose gnomon casts a shadow. I think I can now properly formulate my question:� Is there a way to get the sun's rays down to my room so I can have them illuminate an ordinary sundial?� (Without demolishing my neighbor's house or spending a ton of money?)
