I'm not convinced.

Do you realise the biomass you would need to produce oil on the scale you are suggesting? Plus these bacteria, if they do indeed produce oil of the right grade and composition, do not do so out of thin air: they need their own metabolites to process, and where will they come from? Even if its possible, I do not think this is a viable or sensible solution: we need to move away from oil. Think of oil as the "tasty but very bad for you health" saturated fats of today's global economy...

Again, biofuels are not carbon neutral, and they use up a lot of arable soil that we are going to need if we are to feed everyone on this planet. I don't think we can afford to give up the 30% of arable land expected to be needed to replace oil to any comparable level; not at the rate humans are spawning left, right and centre.

And, frankly, even if oil needs could be met continually, do we really want to keep using such dirty fuels if there are cleaner and cheaper alternatives waiting to be developped? If in doubt take a few breaths from an exhaust pipe and see how good one feels...

Personally, I expect that there will be a period of clutching at straws and trying to hold on to the IC concept, but I think electric will follow. And why not? after a few years of demand for better products I expect battery technology will come on in leaps and bounds. Imagine a bike where you can map the power delivery,at home, not by tweeking fuel maps or carbs, but simply drawing a graph on your laptop and uploading!! Two stroke power bands without the smoke and rebuilds!! Brilliant!
