$this->bbcode_second_pass_quote('Oil-Finder', 'B')ig research projects on potentially huge engineering projects using new technologies takes years. Not only do they have to test the technology itself, they are probably re-testing it, making tweaks as they go along, trying new things, etc., so on, and so forth. If that weren't enough, they have to conduct environmental studies, get water rights, do a political dance with the state of Colorado, local governments and DOE, and a whole ton of other things. All this isn't something you can do overnight.
Quite. And you still hold out hope for this stuff making a significant contribution to the solution? Well, I guess that if you believe that new discoveries can keep (relatively) conventional oil production slowly rising, then you might possibly believe that oil shale production can start to be significant before serious declines kick in. Shell, of course, don't need to believe that, they only need to believe that they can make some money from the project. I don't have much problem with Shell believing that but, even with FreddyH's figures, I do have a problem with the notion that oil shale could be a significant contributor to our energy needs before we hit a crisis.
This is why it wasn't an aside to your request to pstarr. It may not have answered you directly but it gave a possible/probable interpretation of what he was getting at by his remark. If you really want to compare the energy densities of a baked potato and oil shale, I'm sure that it can't be too hard to do that, though it may take a day or two of digging around for the information. Personally, I've always taken the phrase to mean "oil shale energy density is a small fraction of that of conventional oil". But I've seen arguments about that as a valid comparison, too. I guess we'll see when those oil gushers start appearing in those Colorado hills. If I'm still around.
