@farmerman,
Nope, it was the Day of...
In on of the movie vrsions the triffids were outfitted with silicone sets in their calyx , into which fit a "driver"
Hy, Im finding out **** I didnt recall from my chilshood.
I looked at the names of the books that argued the case for silicon CENTERED life (qnd even though the chemistry says that a silica based lifeform would need a high temp to be stable by Gibbs Phase Rule, it coul happen)
Like the War of the Worlds, th trees could be set in an environment where their roots would tap into the earths MANTLE nd derive a temperature below which silicic acid could become the main vascular fluid of the plants (xylem ) or was it Phloem? (I forget which gos up and which goes down)
