But perhaps we shouldn't rule them out completely, even if not appropriate in this particular application? (I'm going to leave out taste, though, as licking the parts of a public sundial might raise some eyebrows.) The increased temperature on one of a number of areas could cause a scent to evaporate most strongly there and be most detectible e.g. at one of a number of openings. And a mechanical linkage operated by temperature could alter the frequency of vibration of one tuned element relative to others so that a change in pitch could be discerned? (I don't think the straightforward effect of differential temperature on elasticity and linear dimension would suffice unless some odd material with something akin to a phase change near the operating temperature for the day could be used, nor would the change of speed of sound in air on a tuned cavity resonator or pipe be enough.) Not easy to accomplish - but when you next come across the Smellodial or the Suntuner, remember, you saw the idea on this list first (Or did you??) ;-) Regards Andrew James This correspondence is confidential and is solely for the intended recipient(s).
