In a feat of enterprise and endurance, Hans Tholstrup drove a solar-powered car across Australia in 1979. The car had a large flat roof arrayed with photoelectric cells that turned the sun’s radiation into electricity and charged a battery.
Solar radiation cannot deliver more than about a kilowatt, roughly an old-fashioned horsepower, per square metre at ground level, and it usually delivers less. ... Read more
Oil price goes down – whoopee
The price of crude oil dropped dramatically last year. This was not unexpected – supply and demand of this resource are finely balanced, so that any political or economic disturbance can cause large fluctuations. ... Read more
Partial Accounting: Another spurious “cost” often used as a basis for policy appears as a result of partial accounting. An urban public transport service might be reduced or eliminated on the grounds that the costs of the service are nowhere near covered by passenger fares, and that costs can be reduced and the nation or city thereby enriched by cutting the service. ...

It is possible for some time to consume a resource faster than its renewal rate, just as a business can for some time consume its accumulated money capital faster than it takes money in (this is only an illustration and does not confuse money with wealth). ... Read more
I was asked recently if I thought that American dominance of the world was over, if America would decline like other great powers before it, and what nation would take its place.

In 1964, the ship Alkimos was wrecked on a reef off the coast of Western Australia at a time when our largest city, Perth’s, suburban sprawl had not reached that far. The ship was Greek but had a varied and colourful history, including on-board murders and criminal activity, under different names and flags. ... Read more
Current economics assumes a world of unlimited resources, unlimited wealth. No matter how rapidly a resource is used, either (i) “They” will always find more, or (ii) substitute resources will always be found to serve to any required extent as well or better in place of the depleted resource. ...

The Australian Government has recently announced revised, reduced targets for the reduction of greenhouse gas emissions. There has been some objection to this but it should not really be surprising.
Governments around the world have shown that they just don’t get it. ... Read more
The factor of people’s expectations, left out of this discussion so far, would change the outcome somewhat.
The effect of rising expectations would be to stop the “boom” and return to “stagflationary” conditions sooner than if resource depletion alone were the depressing factor. ... Read more
