Re: Countdown to $100 oil (50) - it's not 'oil', i (4.00 / 4)

Somehow I've gotten the idea there isn't a liquid fuel replacement for oil when considered gallon for gallon. So measured in dollars-for-ergs any replacement is necessarily more expensive and less efficient.

True? False? Half-truth?

My impression is it's a truth.

But then we will hear the argument that says it doesn't matter if liquid this or liquid that is cost/energy less efficient than oil, we can pay a premium for the fact that liquid fuels are useful and indeed necessary...

To go on running a civilisation that... needs liquid fuels...

Re: Countdown to $100 oil (50) - it's not 'oil', i (none / 1)

biodeisel is pretty close -- 7-9% lower per this source:

I'd be willing to bet if energy/gallon were critical, they're be a few PhD ChE's who'd develop ways to close that gap. But I'd guess the real issue is energy/mass since how much mass you have to haul around hits your econs more than stretching a fuel tank's size a bit.

No, that is the gross energy content of ... (4.00 / 2)

... a gallon of biodiesel, not the net energy yield of a gallon of biodiesel.

I've been accused of being a Marxist, yet while Harpo's my favourite, it's Groucho I'm always quoting. Odd, that.

In terms of net energy yield... synthetic liquid fuels from nuclear might have a shot.
