The sap rising is driven by heat cycling through the night and day. Overnight it's often below freezing, during the day it's often above freezing this time of year, and even when the air temperature is below freezing a tree with southern exposure will probably warm up through the day.
There are several different approaches for collecting the sap and concentrating it into syrup. The typical approach is to boil it, often with wood, especially if someone has a wooded property. However, there are many other more sophisticated/less resource intensive approaches too. Some people freeze dry the sap before boiling, for example. The ice effectively removes much of the water. Some people vacuum dry the sap all the way into syrup. There are also some reverse osmosis methods for producing saps. Presumably each approach has pros/cons.
A few friends of mine and former classmates of mine produce syrup every season. Some do it on small scale, some have an farm scale operation. Some retail the syrup themselves, some sell it through various small shops. There are also people who make the syrup into whiskey or other more processed goods. I think most people do it as a hobby, rather than a serious money making opportunity. However, when you own your property outright and have a low cost of living, even hobby farming activities result in a "profit", maybe of hundreds or low thousands of dollars.
