This technology promises to expand the amount of fissionable fuel available from natural uranium by a factor of about 60, by “breeding” more fuel than it consumes. This doesn’t change the non-renewable nature of the total uranium resource, but it does promise to make it so abundant as to encourage a casual attitude towards energy conservation. ... Read more
It is necessary for a lender of money to charge interest because the purchasing power of each money unit is generally expected to fall with time. This has been the trend historically and the very operation of the economy tends to make it so. ... Read more
A fault of flat earth economics as practiced in free enterprise economies is that it chops a nation’s economy into sections that are too often treated as being self-contained and independent of other sections. This is not a useful or realistic view. ... Read more
The direct addition of value inflation to the rate of price increases is quite small. The larger effect arises from secondary influences, in whose shaping human psychology plays an important part. These influences are triggered by the small value inflation component and its corollary, a slowing of the rate of net throughput increase relative to gross throughput increase. ... Read more
In Australia the federal government is trying to implement an Emissions Trading Scheme to combat global warming. Opponents of this scheme argue that it will cost jobs.
Surely the whole point of trying to slow and stop global warming is that if such warming continues unchecked, it will cost millions of jobs, and lives, worldwide, because of the destructive effects of changing climates and rising sea levels. ... Read more
Another misconception held by many in both “rich” and “poor” countries is that the “rich” should go on making and using ever more goods and services, thereby “creating wealth” that can somehow find its way to the “poor” nations, making them “richer”. ... Read more
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
The principle of consuming resources at a rate no faster than their rate of renewal appears to be untenable in the case of resources whose renewal rate is almost zero, as is true of fossil fuels, gas, oil, and coal, also fissile uranium and thorium. ... Read more
The extraction of minerals often leads not just to the consumption and depletion of the mined material, but also to the unintended but unavoidable consumption and depletion of rich and necessary biological resources, which are quite wasted in the process. ... Read more
First, it will be noted that things that common sense tells us are always good, such as efficient government or nuclear disarmament, or always bad, such as strikes or cartels, may actually be bed sometimes and good other times depending on the circumstances. ... Read more
