Crisis point

With the sudden escalation in the building/establishing of wind and solar farms, it has become obvious that there is not a politician in this state or this nation who is the least bit interested in the cost of energy to the consumer or its security for the future.

All the talk from politicians about lowering energy costs makes one wonder how they can face the public with such rubbish when they are following the path of energy insecurity, they obviously take the public for fools.

Our energy crisis has reached the point of no return.

Future generation will, in all likelihood, face the challenge of providing their own energy which in itself will create enormous problems for society.

This country has become nothing more than a piggy-bank for greedy industries (most of which have overseas interests whereby money is pouring out of Australia in flood proportions) and even greedier share-holders at heart rather than Australian.

A future of doom?

Many will scoff at the thought but it’s becoming increasingly obvious!

This nation stopped advancing as a cohesive body several years ago.

We have a national parliament that is all but dysfunctional; it seems each and every one is hell-bent on scoring political points on the opponent and to hell with the nation!

Talk about Nero fiddles while Rome burns.



Oil won’t bring boom

I’m not opposed to oil exploration in general, but to my mind the notion of drilling a hole in the seabed in two kilometres of wild Southern Ocean water, using a big floating rig, positioned by GPS guided thrusters seems to be risky in the extreme.

The failure of a gear box, coupling, any part of the drivetrain, or any other mechanical or electrical system would likely result in the loss of a thruster.

The loss of the signal from the GPS or failure of a related electronic system would result in the loss of all six thrusters and with some folks talking up the concept of a future war in space, it’s a distant but finite possibility.

Many years ago I worked on an oil rig in the Cooper Basin, after a background in mechanical engineering in the Whyalla Steelworks.

I did a rough conservative calculation of the wind load on a big oil rig in a 60-knot wind and came up with a number of around 350 tonnes.

Apparently the six azimuth thrusters will make about 240 tonnes in total, running flat out.

The Deep Water Horizon blowout proved to be enormously difficult to cap, and it was in just 60 metres of water, not 2000 metres of notoriously rough and unpredictable Southern Ocean water.

And as for the mini economic boom that will supposedly result from the drilling, I was around for the three decades or so during the previous 23 or so drillings, and even though it was talked up at the time, I don’t seem to remember any noticeable great economic boom during any drilling program at the time, and I’m not sure why this one would be different.
