Chloroplasts (in eucaryotes) and cyanobacteria (procaryotes) harvest energy
from light. Cellular ion pumps create voltage gradients across membranes.
Cellular organelles (ribosomes and ?) produce a variety of energy-storing
fuel candidates: ATP, oils, methane, methanol, ethanol, and others. The
DNA bio-code for these particular products and processes and the structures
which mediate them, can now be identified, isolated, elucidated, precisely
customized, reproduced, and then systematically mass-produced.

Though arguably a non-trivial process (everything's hard till...), these
disparate pieces of biological evolution, along with whatever
post-biological modifications prove advantageous, can be envisioned
conjoined to create never-before-seen-or-even-imagined, truly "engineered",
biological-yet-synthetic organisms. Every code variation across a spectrum
of billions of different organisms from virus to whale, from radiodurans to
cubic kilometer matrices of a single fungus--the largest individual
organisms yet discovered--each piece of DNA a life-tested-and-proven asset
in the bio-engineering inventory. As a technophile and gadgeteer, a lover
of hardware departments, junk yards, and laboratory-gizmos-R-us emporiums,
the vision of this vast-beyond-imagining biological tool kit sets my heart
to racing. No Christmas-eve-wonder-intoxicated tyke was ever more excited
and impatient--and less inclined to sleep.

SHOW ME THE MAGIC!

The dark horse races through the velvet night, chasing the star-lit
infinite, to the coming dawn.

                        Best, Jeff Davis
