| Tatarize ::: Favorites 2008-01-16 19:17:58 Yeah, it makes sense. Just technically a bit off. You can't sell something if somebody else isn't buying it. __________________________________________________ | |
| gratex ::: Favorites 2008-01-16 18:59:21 Supply does not necessarily have to meet demand, this is quite basic reality. In oil market terms supply is already dropping below the real demand for oil. This difference is reflected in the cost and the alternatives used to fill that gap. __________________________________________________ | |
| Tatarize ::: Favorites 2008-01-16 17:08:53 Um, no. Supply meets demand by basic economics. However it seems to meet it at a price of $100 a barrel. The typical ability to produce more and have a greater supply to cover additional demand is now gone. Demand for oil is such that all the oil production is used. If you pay enough you get some, there's no supply at the 20 dollars a barrel it use to cost. __________________________________________________ | |
| Puzzoozoo ::: Favorites 2008-01-16 16:08:41 Indeed so. *My* thoughts would be instead of a big solar plant, Americans should think small, and have more efficient photovoltic tiles on the roofs of all [new]American houses or replace existing tiles on existing homes and have them alligned to the east-west to meet the Sun, to turn each house/home into a micro solar power station, same with factories and office blocks, the excess power could power electric trams for mass transit. Economys of scale can reduce costs. :-\ __________________________________________________ | |
| andhemills ::: Favorites 2008-01-16 14:49:31 I would like to think that that kind of energy production could be translated into clean transportation energy. Perhaps only time will tell. __________________________________________________ | |
| Puzzoozoo ::: Favorites 2008-01-16 14:11:12 Well done. But how is that going to provide for fuling the personnel transportation for the American population, and transit of manufactured goods and raw materials? __________________________________________________ | |
| andhemills ::: Favorites 2008-01-16 14:04:53 In Nevada, we've developed a parabolic solar system which reflects light into a central point (in this case a pipe filled with water to generate steam). Using 15% of Nevada's land, we could power the entire country's energy needs in this way... __________________________________________________ | |
| Puzzoozoo ::: Favorites 2008-01-16 13:32:33 Sooo very true, however to rain on your solar parade, I saw a youtube video the other night when I was looking at videos of rising gasoline prices in America, and on this *one* solar powered hydrogen pumping station, a collection of solar panels the size of a tennis court had to be used, and then it took a good 30min to split enough hydrogen to fill up one car. __________________________________________________ | |
| gratex ::: Favorites 2008-01-16 12:49:19 agreed, it has already peaked. Supply was 12% short of demand in the first quarter of 2007. __________________________________________________ | |
| andhemills ::: Favorites 2008-01-16 11:56:29 So I'd be willing to take a hit and accept that some alternative (gas/oil) solution will be needed to start the ball rolling. Once a solar/hydrogen system is in place, it will be able to perpetuate itself. The REAL problem is how we store hydrogen in useful amounts, safely. __________________________________________________ | |
| Puzzoozoo ::: Favorites 2008-01-16 09:55:33 The silver bullet solution eh. To bad hydrogen requires energy to break it from it's molecular bonds, and the solar devices you're going to use need energy to build them, and solar photvoltic cells are about IIRC 23% efficient, and hydrogen today is AFAIK extracted from natural gas which surprise surprise is a fossile fuel from the petrochemical industry. __________________________________________________ | |
| Tatarize ::: Favorites 2008-01-14 00:18:57 Yes. It peaked in late 2005. Though, that's simply because we haven't matched 2005 oil production. We might manage to beat that record, but it doesn't look hopeful at this point. We're currently dropping at a rate of 3% a year. There are other issues. Such as the tar sands (which might spike the production upwards) is at the very least easing our decline. We're lucky to have 100 dollar a barrel for oil. __________________________________________________ | |
| Tatarize ::: Favorites 2008-01-14 00:17:39 It seems to have peaked in late 2005/early 2006. __________________________________________________ | |
| das27 ::: Favorites 2008-01-03 18:09:30 And how are you going to maintain current or increased demand by plowing fields by hand? The same goes for the rest of your statement. __________________________________________________ | |
