I think that $150m is massively underestimated. just considering development, technological, labour and material cost, just the consulting will cost a significant fraction of that!

300m (984ft) is quite small if compares with mega-structures 1.0km high

However you're missing the real advantages, a solar tower will generate constantly, and will take up less ground space than 300 turbines. So this makes more sense not less
All right all right, I still have big doubts about their claims though. Looking at the Spanish solar tower experiment from a few decades ago, their huge tower produced less than 40 MW of power...so that this produced 400MW I don't think so. Then there's the cost, $150 million for a 1km tower of concrete in the middle of nowhere?

^I don't understand why everyone on this website seems to think that solar towers power output has to scale linearly with height, that would definatly not be my consideration, especially based on the designs released.


A more logical conclusion would be that the power would scale with the area of the catchment area, which would be a squared relationship.

This is incorrect. The power output increases exponentially with the height of the tower. A 1000m solar chimney produces almost 3000 times as much power as a 250m one. So reality is actually opposite of what you are saying: these are actually only economical at very large heights.

True ... I wonder why they will spend so much money on this when there are more important things to spend it on given the country's weak economy.

I think the first one of these to be built will be far more expensive and problematic than subsequent ones built around a similar design. I believe one was considered in Australia for the region around Mildura.

The Chinese have been putting a lot of time and money into solar power research and I wouldn't be surprised if the first one built was a Chinese companies initiative and was funded by Chinese capital.

If this was somehow economical, it'd totally love it. Seeing these around the world, maybe even in regions of locally low population density. Plain white concrete rising 1km from the grass plains in Africa or the Sahara, that would be SciFi.

How much energy will this produce/ how many people will it provide for to give a prospective?

^ There's a possible project Arizona that will cost $750 million, and produce 200mw of power.

It said, wen there was the one for Western Australia, but I cant remember now, all I know is that back then it said, the energy has to be converted to electricity and sent towards the cities as soon as it was generated, because the technology doesnt yet exist to store solar energy, if they have developped one in the last 2 years, im not sure :}

Why do you think Australia has a weak economy? Per capita, it is in the top ten in the world...

If you read my post and quote, I was referring to Namibia, not Australia.

That's quite cheap- some Israeli companies are building a few big solar power plants at the cost of 2 billion NIS (~540 million US$) for 100 mw- but these solar plants will be built with the proven technology.
Is there a single solar tower which is actually U/C and not just a vision?

I'm pretty sure that some king of technology exists- but it is very expensive and requires large amounts of space.
Anyway- it won't be needed until countries start to produce more than 50% of their electricity from solar power- and this isn't expected till 2030 and even later, and by then some kind of technology will be probably developed.
