Hi guys, as many of you probably have knowledge of the Dyson Tree Concept-A Dyson tree is a hypothetical genetically-engineered plant, (perhaps resembling a tree) capable of growing on a comet, suggested by the physicist Freeman Dyson. He suggested that such plants could produce a breathable atmosphere within hollow spaces in the comet (or even within the plants themselves) utilising solar energy and cometary materials, thus providing self-sustaining habitats for humanity in the outer solar system.
A Dyson tree might consist of a few main trunk structures growing out from a comet nucleus, flowering into branches and leaves that intertwine, forming a spherical structure possibly dozens of kilometers across.
I was just wondering if one you, many accomplished individuals, could suggest a possible way by which the water extracted from the comet could be moved up to the photosynthetic apparatus and back, in the Dyson tree. Perhaps something involving heat gradient. Any proposal is welcome. Thanks
