It didn't make sense to us, as multiple companies working
for three decades have spent two-digit have not managed to
do it. They've been on the verge on a very long time.

You need a lot of money in already the first round, that
was not feasible for our environment. Yours might differ.

The problem is more difficult than it may appear. In order
to produce just liquid fuels, closed bioreactors are out
of question, so you're operating in an open system, and
competing against wild type. Energy-efficient harvesting and
liquid separation are *not* easy, assuming you have a
stable high-yield type in an open system at all.

This doesn't apply to pharma/cosmetics, and sufficiently
high-priced educts for chemical industry.

So it's not hopeless, but you'd get much more traction
by just feeding a synfuel plant with PV input.
