Survival Cucumber [TL 11]
[GURPS 4E]
Cucumis sativus machinatum
It remains, primarily, a cucumber: you can still eat them. However, should one find themselves trapped on a hostile planet that chews up machine technology and spits it out, then the Survival Cucumber is invaluable.
To begin with, it’s hyper-nutritious; one standard cucumber will support a human for two days. If the ends are cut off, it becomes an almost perfect water filtration device. A Survival Cucumber used as a filter can last about a man-week before it wears out; fortunately, Survival Cucumber vines can grow pretty much anywhere, and start providing new Cucumbers three days after planting. The vines are bioengineered to limit their own population growth, so no need to worry about runaway colonization.
