The main problem with solar is how to store the energy. That's why wind and solar make good partners. Wind obviously doesn't need any sunshine and produces more power during bad weather when solar is producing very little and none after dark. Wind and solar should not be competitors. More effort is needed toward cooperation and developing bigger and cheaper batteries.

In the UK they are building a 50 MW liquid air power station to store excess wind energy - it will liquidise air under pressure, and when demand rises release the air through turbines to generate electricity. Emission free and no issue of batteries requiring scarce minerals or needing replacement. Believed to be the first commercial plant using this technology.

Makes a lot of sense, somebody is thinking laterally.

Pumping water uphill to harness kinetic energy is nice and simple, but does require the correct terrain and takes up a lot of space, Australia has an abundance of both. This technology that Rick has revealed should not take up a huge amount of land, could easily fit into an industrial area near any big city. Sounds good.

That system is more sophisticated than the ones along the coast in the south of Thailand. That water in the oversized pond is pumped up there with windmills that produce no electricity, only pump water. There is a pond overflow that drains excess water out of the pond for when the wind pumps more water than needed. The water going back down powers the turbine generator 24/7. I thought it was quite clever. They were producing DC power and were looking at a way to produce AC power because the voltage was so consistent.

Hi Glait
We have a few similar style hydro systems in Scotland. They contribute to the national grid during the day when demand is highest then use the excess power at night (lower demand) to pump the water from the lower catchment reservoir back up to the higher level reservoir to start the process again when daytime demand rises. There could be many, many more but people kicked up holy poo at the thought of lots of the scenic glens (valley's) being turned into Lochs (lakes) Price to pay for any renewable system whether the land is covered in windmills, solar panels (PV) or hydro systems. Think you will find that all solar (PV) systems produce DC power as they basically charge large banks of batteries which then are fed into invertors to convert DC to AC this resultant AC power can then either be used by a private user or fed into the national grid system. Most hydro systems use alternators as their electricity producing medium which gives AC without having to convert anything.

First time I have heard of that possibility. Certainly seems that it is going some way to counter the 'no wind' problems that wind powered systems have. Hope they keep us updated on the progress.

There has been a plant like this in South Australia for 25 years. Uses a parabolic mirror reflected onto the salt.

Again excellent idea and very suite to the largely empty Nevada Desert with nearly year round sunshine. Will have little use in Northern Europe as space and year round sunshine in short supply. The only way I can see this working in China is at the very dry western areas but even those have sufficient sun problems.

Is it connected to anything?

What is the name of this South Australian power plant/station

https://en.wikipedia.org/wiki/List_of_p ... _Australia

Seems to be only proposed or under construction

[bluejets]

Went down the gurgler.......cost too much and no funds.

Must be off the grid, top secret

If anyone recalls Michael Moore's last movie, Planet of The Humans, they went to Daggett CA, the place where mirror-based solar energy or CSP was developed and the where first CSP power plant was built and found it had disappeared.

Meanwhile, the world-famous CSP at Ivanpah in the Mojave Desert has struggled to fulfill contractual deliveries throughout its history.

Up here in the boonies of Loei there are huge tracts of land that are still not connected to the electrical grid. Thaksin came up with the idea of solar to make the life of these poor farmers much better. He convinced fledgling electronic companies to build small solar systems. The government installed these systems and the farmers made a small payment every month. I looked at one of those systems quite a few years ago and was surprised to see the old original systems still working. They used two solar panels and one battery that powered lights and a small refrigerator. That was when I decided to build a small system myself.

The rainfall up here is not very consistent and the farmers off grid were irrigating with deep wells and diesels. A small group of local Thais started a company installing solar systems for irrigation. My wife has two of these systems. They use just solar panels and DC deep well water pumps, no batteries. The more sunshine, the more water they pump. I don't know how long these systems will last but the small company guarantees them for a year. Her first system uses six 330 watt panels and pumps a surprising amount of water. She still uses a diesel tak tak to pump water from a pond but pumping from a pond is quite simple and efficient. The solar system refills the pond when irrigation is not needed. The best part is that the systems are totally automatic, no controls to fool with. So far the systems have been trouble free.

So because you cannot find it, it does not exist.

Let me tell you how I found out about this. I was attending a local government event at the Holiday Inn in Darwin, December 2007, my company had a exhibitors stand. Like many of these multi day events, there were social events, drinks after the conference lectures, dinners etc.

At one of these I was at the table of the Mayor of Port Augusta, he was there with one of his councilors. They told me about the system. It uses parabolic mirrors on salt water to desalinate and create energy.

So instead of being a smarty pants and inferring I am lying, do your research you *****.

Not lying but not telling the truth
been operating 25 years in SA not true
operating 2007 not true

but what is, is this farm
Sundrop Farms, a tomato production facility that is the first agricultural system of its kind in the world, celebrated its grand opening in Port Augusta, South Australia, Thursday. Oct 2016

Please do some of your own research and try reading your own source info

[Whistler]

I already quoted my source, do I remember word for word a conversation 13 years ago, nope, it took me a little while to remember the date, so what, it was a long time ago, what were you doing on the evening of the 5th of December 2013? Did I talk to the Mayor of Whyalla, absolutely. Is there a project in SA using parabolic mirrors on salt, yes.

You are hell of a nitpicker. I always said a well balanced kiwi is one with a chip on each shoulder.

There is no need to be rude to people about what they post, but it seems to be SOP for you. So from here on in I will ignore your bad manners and will no longer respond to your drivel.
