The con I'm referring to is in the solving of the problems we have with regard to cheap oil, cheap fuel and cheap energy for the _now_. The recent investments in corn, sugar cane, etc, etc on both sides of the pond... for the most part are gov. sponsored con jobs imo. There is probably some valid research going on, but my cynical mind sees Mr Bush delivering (well, regurgitating) a speech mentioning switch grass that has "Go Back To Bed" written all over it...

Solutions to cheap oil problems for the now do not currently include biofuels, because they currently need cheap oil to produce... :s

(Oh, and don't mention whale oil... the last thing we need is the Japanese using more of that kind of biofuel... )

Surface bitumen as it is has a recovery rate of 20%, whereas those applying the SAGD method get as high as 60%. That's a huge difference. For decades in the tar sands, they've been experimenting with various methods to extract deeper oil. I'm guessing there are still developments to be made. Oil price is the biggest factor for development, but the impact of the technology should not be underestimated.
AFAIK, that method is the only reason those heavy oil shales, sands and tars are economically viable at ~$35 rather ~$100... IIRC, even lovely light crudes become commercially unattractive to produce at oil prices of around $15 to the barrel (if i remember the harrowing cries from opec in the mid-late 90's correctly) and uneconomical sub $10 per barrel... Barring miracles, i don't think there's an awful lot further to go after the improvements that were made in the 80's for those very heavy oil shales and sands...

Also, the oil companies will surely remember the burn they 'suffered' from very heavy crudes when oil dropped from ~$70 per barrel in the early 80's to $20 pre barrel and less in the 90's.

No giving up in research for biofuels, but we should be applying technologies NOW to reduce demands on cheap oil asap...

Things like this:

Together with emergency roll-outs for electric vehicles, liquification of coal for trucks, etc, etc...

The fallout from permanently higher, post-peak cheap oil prices could be pretty scary... we need to delay that as far into the future as possible, and the clock is running down fast.

From wikipedia's peak oil entry:

Quote:
Peak oil production has not been reached in the following nations (these numbers are estimates and subject to revision):[137]

* Iraq: 2018
* Kuwait: 2013
* Saudi Arabia: 2014
That's pretty much the West's cheap oil supplies. Prices will be heading towards Jupiter from then on.

We won't be heading back to the stone age like some wacky predictions, err, predict, but oil prices are going to keep on climbing for quite some time. We need serious, nigh on draconian mitigation measures in favour of electricity and some sort of great leap sidewards away from the internal combustion engine - and fast... or else we won't be able to afford synthetic rubber tyres for our electric cars.

Anyway, this getting a touch off-topic i think... sorry!
