Comment on LETTER: Removing sand from the Todd makes no sense as a flood mitigation measure by Steve Brown.

When the water flows so does the sand. When it stops being carried by the water it settles at the height of the highest sand dam, stopping its movement, the causeways.
So the sand Level is determined by the height of the causeways. This means that when a logjam dam is formed against the casino crossing (Taffy Pick) the sand height rises towards that level and if the water runs long enough, will eventually reach that height with a corresponding increase in sand level all the way back up the river.
It would be great to take this crossing out and replace it with a bridge but for the moment it is too expensive, unless you are volunteering huge rate rises, Charlie.
It is a simple engineering fact (scientific) that if you concentrate the water flow into a channel it increases the velocity of the water. This in turn means that the water carries more sand which in turn has the effect of clearing a deeper wider channel through the sand which increases in dimension with the water flow. In short, you use the water to clear the built up sand. If you cast your mind back a while, Charlie, can’t give you a date, but this method has been successfully several times in the past.
Given that sand is always being taken from the river further down I don’t see any reason that if sand is to be removed rather than pushed aside to form a channel, that those who are mining it further down couldn’t take advantage of mining it a little closer to town for a while, creating the channel for us at little or no cost.
@ Dave if you mean by ominous that we might actually take the matter in hand and do something as opposed to running around espousing all encompassing motherhood statements such as Best Practice then you are probably right Dave: We really are ominous.

There’s more to renewables than sunshine
Until now every drop of water that was ever on the earth has remained on the earth.
Wouldn’t it be the ultimate irony if quasi religious climate fanatics were eventually responsible for using up that water, turning it into hydrogen?
It would be even more ironical that we should consider that in one of the driest places on earth, where water is absolutely in its most valuable state as water.
We should all understand that there is no such thing as free energy. There is always a price and generally speaking it would be a pretty bloody smart idea to understand that price, monetary or otherwise, before we go racing off creating even more mammoth environmental issues for future generations.
For the present there are so many ifs around the Hydrogen idea that – dare I say it – it’s simply a pipe dream!
Also noted the quick duck for cover by Mr Duignan when the question about feed-in prices for home solar generators was raised.
Whose issue would that be then Mr Duignan? Wouldn’t that be the Territory Government and given that Territory Generation is in fact a quasi public service operation owned lock stock and barrel by Territory taxpayers, maybe a more responsible answer would be in keeping with that role.


Community solar: the devil is in the wires
Yes, and then there’s all the community facilities of which we are all joint owners! Places such schools, hospitals, police stations, street lighting, ecetera, the list is endless.
All of these facilities require power 24/7 as does welfare housing, hotels and motels, all connected to the rest of the grid.
Consumers on the remaining grid would, as they do now, have to pay their share of those costs, plus, the share of those in the community system.
This is already occurring of course, on a smaller scale, and the costs to the poor old hapless consumer who can’t afford to instal solar, are already escalating.
The only fair way to rectify this imbalance, which of course nobody wants to hear about, all studiously avoiding the subject, is for owners of solar systems to pay their share of those costs!
Another words, pay not only for their use of the grid, but for the existence of the grid.
Yes, even if they are operating a stand alone system.
This of course effects the whole viability of installing solar, dragging its payback time out by quite a bit.
However, if we are to honestly asses the true worth of solar to the community, then these costs really must be taken into account.
It’s time the rose coloured glasses came off, frank and honest assessments are made.
Governments parading solar as world changing advancement are often actually subsidising its installation while blithely ignoring the true and growing cost to community. Just face up to, and come up with, some fair and equable answers!
Now we seem to be adding lithium iron batteries to the mix, as if they are some kind of nice environmentally friendly answer to our storage problems, when to my eye, precisely the opposite is true.
I am an enthusiastic supporter of the idea of renewable power but it must be truly honestly viable, covering all the costs, and it absolutely must create less pollution than our present systems of generation or we are all fooling ourselves.


Ratepayer, do you want your money back?
Such an astoundingly naive proposal could only ever have originated with one Councillor Melky. As always grandstanding without the slightest thought given to the actual consequences of such a profoundly counter productive decision. Which if carried out to the letter would see a good deal of the windfall funds blown in the name of community consultation. Any attempt to refund it would incur even greater costs reducing any refund to a piddling amount producing no worthwhile outcome for the community, especially when you consider Council has on its books many unfunded, or even worse partially funded, or non completed projects that could have, and indeed should have, been funded partially or otherwise from these funds! Benefiting the Community and its economy as a whole.
More importantly, not wasting a huge amount of Council’s time and productivity messing about with a messy, unproductive, time wasting and resultantly expensive, refund. Further to that should Council do the sensible thing and allocate the funds to other projects, it will also provide Councillors with a very good argument against further rate rises next year.
Something I am quite certain, all Rate payers would be relieved to hear.
New councillors need to be across and take responsibility for their role as Body Corporate style managers of their Community’s assets and not to be so easily be duped into making what may seem on the face of it to be responsible decisions but which are in fact cheap political attention seeking ploys with no regard for what may well turn out to be far reaching consequence…
Take time to think it all the way through…
Before you act!


Bottle shop cops ‘security guards, paid for by the taxpayer’
From the moment the POSIs were implemented they have proved themselves to be the single most effective crime prevention measure the Territory has ever seen.
Now I don’t know about you Paul McCue but I would much rather have my family home and business all kept in one piece as opposed to paying out my hard earned to employ a police person who gets greater job satisfaction from aftermath policing!
A person who apparently has so little empathy for the public’s plight that they would actually ask for our support in that role but not in the preventative role!
Call it self interest if you like Mr McCue, but I like many other Territorians, through the voices of our politicians, are going to keep on insisting on the POSIs wherever they are needed.
If we have a police staffing issue employ more police – just as we have been promised on many occasions over the past dozen years.
Fill all of the roles the community requires, not just the roles that suite you!


Pine Gap and the Nobel prize the Oz government ignores
@ Hal: My reference is to Russell’s dad escaping the Germans and arriving in Australia.
Given that he escaped Germany during WW2, if he then set out for Australia he would have arrived during Australia’s greatest hour of peril, facing an imminent Japanese invasion.
Out of the frying pan almost into the fire, bar for the intervention of the USA.
