There are a number of memory metal devices used as actuators. also bimetal strips are used as actuators. both temperature driven. but not continuous output devices like a motor. I did see a loop of two way memory metal used to power a toy boat. a candle heated the wire loop and then the water cooled it. the loop ran verticly between some rollers so that when it was heated it tried to straighten and caused the loop to rotate. I guess that would qualify as a temperature driven motor. Never seen this mechanism used for anything useful.

Yes there are, but none are really self running, (yet). The sterling motor is a close example, but it requires a candle or other heat changing device. If you look up sterling motors you will find several other devices in the links of the sites run by that group of hobbiest and professionals.
