Hi Kurt,
This idea of making diesel fuel from oil in algae is not be as experimental as you might think. See http://www.sartec.com/<http://www.sartec.com/>

I think it is highly unlikely that any process but photosynth would do
this economically. We use carbon and heat to extract metals from ore, to
extract H2 from water and so on. This works because C is a highly
effective O2 grabber. All these processes end up with CO2 as the end
product.
So photosynthesis will do the job. There is a whole mob trying to grow
algae, which does the photosynthesis job quite effectively. Their main
idea is to produce veg oil to run diesels. Many of them are proposing
their processes to scrub CO2 from powerstation exhaust gases. The
resultant algae are biomass and after drying could quite easily be
pyrolysed to provide char, which could possibly be used for TP, or
perhaps fed back into the powerstation. The algae ponds would thus
become giant solar collectors, with the powerstation merely converting
the biomass energy into electricity. The process is still highly
experimental.
