I’m looking at some statistics for air freight traffic and air traffic is differentiated into general aviation and certified route air carriers. I was wondering whether most air freight is shipped using certified route air carriers, or whether a significant portion is shipped using general aviation.

I really enjoyed reading this. It makes me nervous about what it is going to be like when I have kids.

Comment on Update on the (un)economics of shale gas by Steve C in PA

Derek – looks like Art’s re-evaulation is being confirmed. The USGS cut its original estimation of recoverable natural gas by a factor of four (“Geologists Sharply Cut Estimate of Shale Gas” – NY Times, 24-Aug-2011). Also – what about another unitended consequence of fracturing: an increase in seismic activity. Was the recent Virgina 5.8 magnitude earth quake related? We’ll never know for sure. But that was an unpleasant experience (here in eastern PA – 250 miles north of the epicenter) and living and working in buildings not designed to withstand such tremors, not to mention the various aging nuclear power plants dotting the east.

Comment on Hubbert Linearization Debunked? by Greg

Hello:

Excellent analysis!

I would like to know what the world production curve would look like if:

(1) The exponential fit was true
(2) The logarithmic fit was true

It is bell-shaped, like a linear fit would give?

I have agreed to give a presentation on February 26th, but the details (subject, place, time) have yet to be worked out.

If you – or anyone else – has connections to local high schools that might be interested in a presentation (or series) on oil, food, transportation, etc., I would be more than happy to make the time to do so.

Really enjoyed your presentation last night in Wedgwood. This would be the perfect presentation to give to high schoolers. You’d have’em totally engaged! Any more presentations scheduled soon?
