Dyson Tree
« on: 21/09/2008 18:29:46 »



Hello.
We're trying to figure out a mechanism for moving water to top (canopy) for a genetically engineered tree, that is able to grow on a comet and which is able to extract water from the comet and becuase of the lack of gravity can grow to a VERY large height. Can any of you make a suggestion on how water could be transferred to the top. (NOTE: light would be captured from a near by sun). In this situation one has to assume that the tree would be able to obtain water.

Sorry to rain on your parade again,
but this same "lack of gravity" (microgravity) would mean that any oxygen produced by these trees would be lost to space.
Comets do not have sufficient gravity to hold onto an atmosphere, their tails demonstrate this.


Some do believe that the interior of comets are kept liquid by radiogenic heat, but they are a minority group...
