Be like the beaver: build more dams : Comments

By Viv Forbes, published 2/3/2016

Luckily, our sun is a powerful nuclear-powered desalinisation plant. Every day, solar energy evaporates huge quantities of fresh water from the oceans.

The author is getting his wish fulfilled...CO2 keeps on increasing. There must be some reason why those pesky temperature records keep getting broken. I blame the greenies. And the solution is so simple; just put twice as many dams on the same river and get twice as much water.

The more dams the better!

Victoria had a perfect place for a dam on the Mitchell but after putting all the infrastructure in place, pulled all the men and machinery out, built the dam on the Thompson so that the city could get the water and the farmers of East Gippsland missed out. Gippsland also missed out when the Snowy Mountains scheme diverted all the water from the Snowy to the north.

Given recent advances in solar thermal power and desalination (operational data, not theory) that even includes reliable peak demand applications, and for no less than the rollout of comparative coal fired power.

Produce cheap power that will be eminently suitable for equally large scale low cost desalination projects!

Some of which could be sited alongside a new two lane inland canal?

And given huge forty foot northern tides, use selectively and alternatively opened flood gates and two lanes to move massive quantities of ultra reliable reuseable water to our parched inland, perhaps all the way to, below sea level, Lake eyre?

And given much of the chosen route would be just above or even below sea level, not the huge engineering project some folks might believe, and able to be accomplished mainly with live aboard nuclear powered ocean going dredges using cutter bars and pumps.

Nuclear power, meaning around 25 years before they need to be refueled, and most of the maintenance limited to easily refurbished pumps and or patched or replaced pipes?

Dredging the very cheapest, quickest method to accomplish large scale earthworks and or land reclamation.

Small bund walls around selected level areas, would allow the pumped material to settle and dry out, before being used as a source of material to build any necessary levees alongside the lower parts of any proposed route! And not too dissimilar from reclaiming sea salt?

Except, the water is allowed to escape from the other end of the artificial man made lake and then channelled back to where any dredge might be operating.

This simple technique prevents turbidity from becoming much of a problem and then produces sun dried material that can be laid and compacted as when and where needed, even if that then involves moving it with towed barges?

And yes, we need to get busy beavering away at projects that just don't drown habitat and trees, but rather, allow more of both.

Or agriculture projects that doesn't also include the destruction of either and required as adaptation to the worst aspects for us, of climate change!

Yes, building dams is necessary to provide water for our growing nation.
But kicking people off their lands to build such dams is the one issue the author didn't mention.
My relatives graves apparently sit on the bottom of the Warragamba Dam.
They had to make a sacrifice so that people in Sydney have water to drink.

This article is a silly as something you would find in the more loopy Greenies sites... that the author seems to read, in order to get worked up about something.

As with all things there needs to be a balance.
