I don't think I've seen this story here yet. Some radically "out of the box" yet still entirely "in the box" engineering.

Sonoma, California – May 28, 2008 – Sapphire Energy announced today they have produced renewable 91 octane gasoline that conforms to ASTM certification, made from a breakthrough process that produces crude oil directly from sunlight, CO2 and photosynthetic microorganisms, beginning with algae....
... differ significantly from other forms of biofuel because they
are made solely from photosynthetic microorganisms, sunlight and CO2;
do not result in biodiesel or ethanol; enhance and replace
petroleum-based products; are carbon neutral and renewable; and don't
require any food crop or agricultural land.
The final products meet ASTM standards and
are completely compatible with the existing petroleum infrastructure,
from refinement through distribution and the retail supply chain.
