These are interesting questions, Old_Curmudgeon. As for fracking, the procedure is being used for both oil and gas. And I've also heard about the old oil wells replenishing. In looking at the stories on this, nobody seems to know why old wells have replenished.
...and also the laws of thermodynamics, that in essence state that conversion from one form to another is always less than 100% efficient. Further, entropy (the measure of all that UNRECOVERABLE heat energy lost in the conversion) MUST increase IN A CLOSED SYSTEM over time. A lot of the nonsense stated in these fora ignores these facts, especially the "closed system" one.
Mr. Dyson, my post was supposed to make all aware of some areas that have to be included in analyses IF they are intended to be rigorous and SCIENTIFIC. I was NOT stating these were invalidators of any proposals, only that you cannot afford to ignore ANYTHING in an honest evaluation of them! For centuries, the untrained have postulated all sorts of "perpetual motion" mechanisms that simply don't stand up to the rigor of the "closed system" analysis.
Fracking or fracturing and expanding the microcracks in the rock within an oil deposit using high-pressure steam has been used for years. It has also been used in expanding the cracks in water wells using dry-ice to increase yield. I'm not sure I'm in support of fracking in Washington as they already seem separated enough. Perhaps the application of some glue would help. The aspect of fracking we're hearing so much about today involves the injection of chemicals that dilute the thick oil and those chemicals might get into the water table. Luckily we no longer need deal with the NIMBY crowd as they have been replaced by the BANANA (build absolutely nothing anywhere near anything) crowd, apparently they've expanded their horizons.
This information about "fracking" is not something that I researched myself. However, I DID hear a comment very recently regarding this technology, and the person making that comment stated unequivocally that it dates back approx. 60 years. Now, maybe it is that your thought is correct, when oil was $20 bbl, it was economically unfeasible to invest in that technology, BUT now that it hovers around $100/bbl., it HAS become the technology du jour! Also, I'm NOT sure about the ultimate goal of fracking ...... is it to obtain heretofore unrecoverable oil reserves, OR is it to obtain natural gas reserves?
One final thought which I also heard in the last few days regarding petroleum supplies. It seems that investigators (exactly WHO these people are I don't know) have uncapped some very old domestic wells spread throughout the Texas / Oklahoma region, which were previously declared "empty", and have found that they are now averaging about ONE HALF FULL again!! So, WHAT does that mean? Is the global oil reserves really a result of eons of decayed dinosaurs, flora, etc., OR is it a naturally replenishing resource from all the modern decayed flora & fauna? Personally I have NO opinion since I am very unknowledgeable in the minutiae of this field, BUT it may be something for the philosophers amongst us to contemplate on a deep level.
Old_Curmudgeon, I'm one of those who was under the impression that fracking was new. If it's been around so long, why has it not been used? Let me guess: when oil was $20 dollars per barrel, fracking wasn't worth the trouble.
At least YOU did see the humour in my post. I was shocked to read so many of the newer ones that kept to the main topic without comment of my sarcasm. Only one other blogger referenced my note.
To me the saddest part of this "energy problem" is that fracking has been a technology in use for the better part of SIXTY years. To read the current news reports or listen to the items on the news programs, one would think that the industry just invented this technology yesterday, which proves how the mass media's into a debate CAN & DOES influence the discussion& outcome.
Finally, ALL of these discussions of "energy" NEVER consider one very basic Law of Physics, which, if I'm NOT mistaken was authored by MADONNA (or maybe Lindsey Lohan??) .........
"ENERGY CAN NOT BE CREATED OR DESTROYED. It can only be changed from one form to another."
Often farms are being bought by investers who hope to own the land for a few years and sell it off, or by families who's parents farmed and then are waiting to sell the land when the markets at its peak. Either way people are not always ready to put windmills on the land because they fear it might decrease the value.
Wal-Mart will hold its second Made in the USA Open Call July 7-8, at its headquarters in Bentonville, Ark. The event will be a repeat effort by the world’s biggest seller of consumer goods to increase the amount of US-made products it sells in Wal-Mart stores, in Sam’s Club members-only wholesale outlets, and on walmart.com.
From design feasibility, to development, to production, having the right information to make good decisions can ultimately keep a product from failing validation. The key is highly focused information that doesn’t come from conventional, statistics-based tests but from accelerated stress testing.
There’s a good chance that a few of the things mentioned here won't fully come to fruition in 2015 but rather much later down the line. However, as Malcolm X once said, "The future belongs to those who prepare for it today."
