Negative Marginal Return--Jet Fuel

In my review of "The Collapse of Complex Societies" I suggested that we have reached a point where increasingly we see negative marginal return in complexity and the costs of maintaining our increasingly complex society--i.e., the cost of a marginal increment exceeds any return or benefit achieved. I cited several examples. Here is another one. The Washington Free Beacon reports that the Department of Defense has been paying as much as $150/gallon for "green" jet fuel (i.e., made from algae) versus $2.88/gallon for conventional fuel. It also lists some other "green" jet fuels that it has been testing out, all of which would require substantial subsidies.
