According to our memories, at 33 feet the forces of capillary action and gravity cancel each other out. We would like to explore how a 100 foot tree can transport water to its top. We are looking for factors that would effect long-term transport. It's 32 ft, and that applies to siphoning.
Capillary action is different because it depends upon the surface tension properties of water.
