| We're entering a period of economic dislocation in the information wave. Just as we did in the industrial wave, and agricultural waves. |

"The finite supply of copper, iron, zink is certainly sufficient to provide the infrastructure needed."
-for how long?
Armin Reller, a materials chemist at the University of Augsburg in Germany, and his colleagues are among the few groups who have been investigating the problem.
He projects how many years we have left for some key metals. He estimates that zinc could be used up by 2037.
Other materials will run out sooner..
Platinum is a vital component not only of catalytic converters but also of fuel cells - and supplies are running out. It has been estimated that if all the 500 million vehicles in use today were re-equipped with fuel cells, operating losses would mean that all the world's sources of platinum would be exhausted within 15 years. Unlike with oil or diamonds, there is no synthetic alternative: platinum is a chemical element, and once we have used it all there is no way on earth of getting any more.
The metal gallium, which along with indium is used to make indium gallium ar$enide. This is the semiconducting material at the heart of a new generation of solar cells that promise to be up to twice as efficient as conventional designs. Reserves of both metals are disputed, but in a recent report Reni Kleijn, a chemist at Leiden University in the Netherlands, concludes that current reserves "would not allow a substantial contribution of these cells" to the future supply of solar electricity. He estimates gallium and indium will probably contribute to less than 1 per cent of all future solar cells - a limitation imposed purely by a lack of raw material.
Reller estimates that we have, at best, 10 years before we run out of indium. Its impending scarcity could already be reflected in its price: in January 2003 the metal sold for around $60 per kilogram; by August 2006 the price had shot up to over $1000 per kilogram. |

mr.afternoon is not considering advances in generation and storage of electrical energy.
Dyesol developed higher efficiency solar panels, including windows, able generate much of electrical energy needed for conventional buildings - particularly with design improvements, so several million buildings may well contribute to the national grid.
Many industries will still need draw significant proportion of their energy from the national grid.
Trains from Sydney to Perth can be electric with solar or hot rocks style power generators contributing parallel to tracks.
The finite supply of copper, iron, zink is certainly sufficient to provide the infrastructure needed.
Oil has substitutes which rising oil prices brings to point of economical.

"I wouldn't mind seeing the worlds population decrease though.."
You wish is granted - (from another thread)
"It is often difficult to tell the difference between Cause and symptom.
In this instance, the straight economics view may be better - "Supply & Demand."
Globally, a massive re-balancing act is under way, due to once in history events -
1. Peak Population (cause - Aging/Total).
2. Peak Climate (Cause - Population).
3. Peak Oil (Cause - Population).
4. Peak Food (Cause - Population).
We have all heard of the female version of an employment "glass ceiling", but now we have the "global economic glass ceiling." From all sides, the global economy is bumping into glass ceilings, which are caused by these once in history events.
Anyhow, back to supply and demand. Economies, have previously been built on "increasing Demand" and "increasing Supply", in short, "Growth".
Initially, an aging population, is already causing changes on a massive scale, as the boomer generation moves from Peak earning & spending capacity, into their "retirement era."
Next, 2 Billion or so, of the Baby Boomers, will die over the next twenty years, putting the global economy into long term decline.
At the same time, population issues relevant to Oil, the global Climate and Food shortages, puts the current economic system of Demand, Supply and Growth into terminal decline.
These Basic precepts are now starting to falter and over the next 20-40 years, many concepts will change.
We now enter a long period of turbulence and danger, with the global economy is being "constricted", like the actions of a "Boa Constrictor" snake, the global economy is having the life slowly crushed out of it.
This is not a downturn, this is not an opportunity for personal or even national economic gain -
This is about the survival of the human species!" |

Olduvai Theory ahs some valid points to it, but I doubt we're going to revert back to a "post idustrial stone age" period as it suggests here - http://dieoff.org/page125.htm
Even with a steady increase in production from other renewable energy sources the comsumption rates of today aren't likelly to prevail for long.
US wind production was up over 30% last year, dwarfing even the most fecund country's population growth. Solar is increasing at a somewhat slower pace.
The biggest stumbling block will be the lack of electrical infrastucture to move the electrons from havest point to the end users. there is a finite amount of raw materials like copper, iron, zink, oil, that can be easily extracted and used.
I wouldn't mind seeing the worlds population decrease though.. |

Someting to think about!
The Olduvai Theory states that the life expectancy of industrial civilization is approximately 100 years: circa 1930-2030. Ackerman*s (âWhite*sâ) Law defines it:
e = Energy/Population.
Four postulates follow:
1. The exponential growth of world energy production
ended in 1970.
2. Average e will show no growth from 1979 to circa 2008.
3. The rate of change of e will go steeply negative circa 2008.
4. World population will decline proximate with e.
Google link for Olduvai Theory follows -

Close gaps, if needed. |

Oil is amazing. Its under the ground but as soon as it finds a way to spurt out, and its on your property, its worth ... ALOT.
Although I dont like it getting into the sea, I think I like oil. |

Crude oil forms as a natural inorganic process which occurs between the mantle and the crust, somewhere between 5 and 20 miles deep. The proposed mechan!sm is as follows:
-Methane (CH4) is a common molecule found in quantity throughout our solar system â huge concentrations exist at great depth in the Earth.
-At the mantle-crust interface, roughly 20,000 feet beneath the surface, rapidly rising streams of compressed methane-based gasses h!t pockets of high temperature causing the condensation of heavier hydrocarbons. The product of this condensation is commonly known as crude oil.
-Some compressed methane-based gasses migrate into pockets and reservoirs we extract as "natural gas."
-In the geologically "cooler," more tectonically stable regions around the globe, the crude oil pools into reservoirs.
-In the "hotter," more volcanic and tectonically active areas, the oil and natural gas continue to condense and eventually to oxidize, producing carbon dioxide and steam, which exits from active volcanoes.
-Periodically, depending on variations of geology and Earth movement, oil seeps to the surface in quantity, creating the vast oil-sand deposits of Canada and Venezuela, or the continual seeps found beneath the Gulf of Mexico and Uzbekistan.
-Periodically, depending on variations of geology, the vast, deep pools of oil break free and replenish existing known reserves of oil |

NASA has given us today incontrovertible evidence that Titan has abundant inorganic methane.
Methane has been synthetically created in the laboratory, and now NASA confirms that abiotic methane is abundantly found on Titan.
If the scientists have ruled out that biological processes created methane on Titan, why do petro-geologists still argue that natural gas on Earth is of biological origin? |

Have you ever wondered how all that 'fossil fuel' came to be so DEEP underground, in some cases more than six kilometres down? Are we to believe that since prehistoric times, six km's or more of solid rock has formed over the top of what used to be forests and peat bogs? I doubt it.
Some of the new 'super-deep' oil wells are striking oil that is in reservoirs undersea, at +200 degrees - thats friggin' hot oil! |
