I see everyone concentrating on oil as a fuel but what about oil as a source of cheap polymers? What is the economics in a system where burning (!) oil as a primary fuel for cars is considered insane because the relative price of plastics (and other materials made from oil) compared to energy becomes majorly unbalanced? Imagine if a barrel of oil was it's current price but energy costs were one quarter and polymers doubled. That's not just a speculation, but inevitable! Eventually the price of oil must reach parity with all new energy sources. The price may very well surpass energy prices. Once energy becomes cheaper than oil... There's going to be some major pain in countries that didn't invest their petrolium profits wisely - although they could use the fuel themselves to help delay the blow. A soft fall would be less painful but would spread their economic disadvantage over many years.
I think the concept of burning oil will eventually be seen the same way as farming before irrigation, crop rotations, soil management, etc. Or like pumping untreated sewage into a lake. A great idea at the time, but obviously it had to end sometime. |

(But, surely someone's already done that. Maybe I just need to Google more.) Used-car dealers could use that as a selling point (or do they already? -- I haven't used-car-shopped since I bought my current car, used, three years ago after my previous thirteen-year-old one, also purchased used, exhibited mucho many disablements). I suppose that new-car dealers with some inventory of used cars for sale might not want to include that in their sales pitches, though. Quote:

Also, note that high oil prices don't boost oil industry profits all by themselves -- it's the sudden increase in value of all the oil that's on its way from well to consumer that boosts profits, temporarily. When oil prices fall, so do oil company profits, but mainly because the value of their unsold inventory suddenly drops. It's basically an accounting matter that will be the subject of the final installment of my explanation for only_human's personal peeve (shared by millions of other folks!) in post #39 of this thread.

The real "REAL" reasons:
Too many people on this globe. Not enough governmental control of people's lives. Not enough group and communal living. Too many people living in "the countyside". Think them through. |

Second, my statements are coming at the problem from a complete oblique angle. I am not talking about the end reasons, rather the root reasons and the reasons for the next and previous rise. You can add to the list: Lack of true spine by politicians. (Pandering for votes and lack of willingness to lead.) |

From the but-I-could-be-wrong department:

Of course, I could be wrong, again. Maybe this could power a home-system-priced steel foundry. Perhaps a photovoltaic cell that reflects most of the sunlight it doesn't convert into electricity might, if used for the mirror material, be good enough for solar heat concentration by a factor of, say, 100 instead of 1000 on the water tube, and thus produce both hot water and electricity in an integrated home system. How'd that grab you, Fusion_power? Last fiddled with by cheesehead on 2008-06-30 at 17:36 |

http://books.google.com/books?id=OEh...um=7&ct=result Start at the bottom of page 208 http://www.montanagreenpower.com/sol.../timeline.html Look at 1861 to 1941 and http://www.solarenergy.com/info_history.html My understanding about the Google solar project is, that they will be using Sterling engines. added: IIRC France had a huge solar furnace that would burn through steel beams, not melt, burn with flames like a torch.
