Re: Biological v. Abiotic?
Abiotic oil is an entertaining subject. As someone who has studied (and profited) from oil depletion, I've reviewed the concept.
I put abiotics in the same category as "drill baby drill", or the assumption that drilling technology can save us from the rapid depletion of conventional oil.
Google "IEA peak oil 2006"
So, please continue to promote concepts like abiotic oil - it ensures that my energy investments (particularly those in tar sand oil producers) will be very profitable for many years to come!
