those solar panals?

if they are there huge!


Also this is amazing:

Solar one and two you talk about uses a completly different concept. They infact focus the radiation from the sun on one central point so as to create a very focused energy on the collector. From there I'm not quite sure how it is converted to energy but that is the fundamental idea. The idea of the Solar tower is that hot air is trapped under the glazing and therefore wants to escape to the cooler air outside-high to low pressure. The tower is the only method for this superheated air to escape and because warm air rises it naturally is drawn to the tower. At the base the large turbines are forced to spin by the moving air and this is how you get the electricity. The tower helps to accelerate this effect.

Well, all of these designs fall under the category of a "Solar Collector" as opposed to a photovoltaic system. Whether its air, salt solution or water that makes the power is the only difference. All use a central tower surrounded by a massive field of mirrors. I think all of these ideas are awesome, 600m tower! amazing.

No we're talking about the one in Australia, as this is the thread for it, not the one in texas. Fail.

Um no they don't!

The solar tower in australia and the one in spain don't use mirrors at all. They use the greenhouse effect to create superheated air under the glass canopy, which is drawn to the centre of the facility via a heat differential. the fast moving air is pulled through large turbines (which create the power) and up and out of the chimney and into the atmosphere.

yes, this project really is a new concept. nothing actually to do with collectors ect. but as avatar said, simple idea of hot air rising up through an emormous stack creating power by turning turbines to generate power.
go to this website and click on "artist rendition of solar tower. great little movie.

It would be even better if the entire floor was layered with solar panels.

no because if you put solar panels the heat would pass trought and the solar tower wouldn t work properly .

There would be no accumulation of heat within the enclosed area if the heat is absorbed by Solar Panels. What you instead need to do is have an accumulation of heat within the enclosed area so that the air is heated and forces it to rise > Only way out is through the Chimney on its way out it'll turn the the turbines with its force producing electricity for your laptop to run so that you can refresh the "WTB - Burj Dubai" thread on SSC = )

i guess they could put those new solar panel things in the glass. some kind of see-though solar panels that they fuse into the glass or something. Hold on, i'll try to find the link.

I thought this smokestack was originally proposed at twice the height....? Sorry, haven't read the thread.

Anyone have some good comprehensive links on this project, and the science and economics behind it?

The whole point is for the floor to heat up. Then the air gets heated, and moves into and up the column. Covering the floor with dark, heat absorbent solar panels makes sense to me.

in the website. be sure to click on small movie of the project. unreal. really gives you instant idea how it works. very simple idea, just on a grand scale.
the 1m thick concrete tower was going to be 1000m with a 130m dia, but now it will be more like 600m with a 65m dia.
Still an impressive structure.It will be by far the tallest structure in Australia.
Our tallest structure is a flimsy 427m guyed mast and tallest chimney is MIM stack @ 270m.

No the whole point is for the AIR to be heated up, If you have Solar panels that are absorbing the heat (which is how they work) the air won't be heated to its maximum potential. The Air Won't heat up if you have solar panels absorbing the heat! You need something that would heat up the air and continue to release the collected heat into the enclosed area for as long as possible keeping the hot air rising.

I wonder why there's Australia in the thread name, not the city this is going to be built? There are strict rules about that I say this won't get built. And if it will, half shorter.
