Japan was reliant on Nuclear Power till the Tsunami.... Now they are returning back to Coal fired energy.... The new generation of coal fired power stations are far more efficient than they were 20yrs ago....

As for Nuclear Powered Stations.... NOT IN MY BACKYARD...

LW....

Sounds like a good plan to me. Put it in the Great South East where they think that that is all there is to Queensland..

Heard a Nuclear physicist on the radio a few months back, Australian guy, can't recall his name?
He was saying next decade 2020s a new style safe reactor will be perfected and on the market.
10 MW generator the size of a shipping container and No Nuclear meltdown risk, using current
nuclear waste as fuel.

In Australia i doubt we will be leaders in this area or be building the new technology next decade
when the rest of the world is, our media distorts the truth and it ends up brain washing public
opinion.

Coal & Oil have been demonised.
So has nuclear.

Solar / wind have limited capacity to take up our entire energy needs.
To run a country you need Industrial generating capacity, solar is OK for homes, farms etc
for part of your energy needs.

I think South Australia would be a very good place to build Australia,s first Nuclear Power Station
on the site of the old Coal one that was shut down, Port Augusta, its not far from where Uranium
is extracted ( Roxby Downs ). :idea: :sunny: :Y:
 
Free roofs for ALL housing north facing, roofing paid for by green groups, all roofing has to be High Output Solar panels tied to the grid - (charge to be stored in rechargable Detectors - SHhhh...)

Their dream come true, as long as they pay for it out of their own pocket, will save the Govt billions.... O:)

Otherwise Nuclear Reef project.

Carrot and Stick...
 
Have a look at gravel bed reactors, the sniz. Also would remind people Sydney is on to its 3rd reactor without any dramas. Though OPAL doesn't produce power it does produce medical isotopes for treating cancer patients across Oceania, as well as making a motza purifying silicon for use in high end electronics (is doping).

Seems like a much better idea.

Most people are unaware of geothermal potential.
Though testing at Loy Yang proved it would be possible to use geothermal onsite at existing
power station. What could be done is bore a hole deep down into the earth and send the cold
feed-water used at the Power station down it then let the earth heat it up and recover the
warmer water by another hole prior to feeding into the boilers at the Power Station, efficiency
gain would be Huge, was an article about it a while back.
 
How about pumping water to the top of high coastal ranges into reservoirs near the main cities with what ever power you want then run it down through turbines as needed. Basically use the reservoirs as a big battery. Most of our major cities have some high terrain nearby and all on the coast. There are many other technological solutions of which modern nuclear is one. France can lecture other countries about carbon targets but they rely heavily on nuclear so its easier for them. Also germany is held up as a great example of using renewable energy but then when things go wrong they inport there power from france to make up the short fall.
 
There are already hydro power stations on Reservoirs near main cities.
Existing hydro in Australia supplies some of our energy needs and any
potential new Hydro source is under consideration but Hydro won,t
supply all of our needs.

Why not pump sea water then return back to the ocean ? Salts probably not good for current turbines but am sure there would be alternative materials that could work ?

The return energy is less than the initial pumped energy, can,t get 100% or greater efficiency.
True, but it would allow you to store a renewable.
 
Well someone should do something soon.... were sick of waiting for the oil to run out and the price of petrol to hit $10.09 Ltr.... fuel coupons.... and essential services fuel only signs at the bowser.
..... meanwhile.... the price of used pushbikes will surpass that of new cars.
..... and basic foods that need to be moved further than locally will be out of reach of all but the filthy rich (and the silver stackers)
My advice... buy some old push bikes and become adept at growing your own.
....oh and if anyone knows a good toilet paper plant to grow... let us know
(no emoticon)

It's standard hydro practice. Pump up when excess power available and cheap and generate at peak demand.

Yes i know this, but until Snowy 2 Hydro gets built its not yet been done here in Australia.
Have visited a site in the USA where they do this.

here is one in Japan

and here is the redundant Port Stanvac oil refinery in Adelaide that my dad used to work at. It was able to take any grade of crude and turn it into fuel. Now we rely on Singapore and others to do it :N: gov will probably sell it off for unproductive housing sorry to be negative.

Like most things, not so simple. There is some possible application of low temperature geothermal (eg Portland swimming pool??), but moderately high temperature geothermal potential only exists in very few parts of Australia and they are very remote (eg northern South Australia). Very high temperature virtually non-existent. Not a new idea and we have been exploring for decades. Olympic Dam have been looking at generating their power that way. The problem is losses in power lines over the huge distances required to get power to population centres.

Like most things, it has issues. Hot rock methods require drilling a number of deep holes (kilometres deep). In many localities the water is not pure, and can require pulling the rods annually to clean them of minerals that precipitate on the way up, clogging them. The process of warming water cools the hot rocks, so new holes have to be drilled in new hot localities every so many years.

The problem being that you are pumping uphill, so conventional hydro wont work.
