Solar Tower - renewable energy green global warming
Posted by admin on Mar 15, 2009
SolarMission Technologies (www.solarmissiontechnologies.com) and its Australian subsidiary, EnviroMission Limited (www.enviromission.com.au) produced this 5 minute video on the pilot plant in Spain. It is an older video (2000) but gives a decent understanding of the solar tower concept. EnviroMission, Ltd. (US Market: EVOMY, Australian Exchange: EVM) is a renewable energy developer of sustainable “green” energy solutions for the energy market. EnviroMission aims to be one of Australia’s …

Beautiful way to make electricity

they should build these above all the big parking lots we have.
tarmac -asphalt gets so hot. + all those hot cars. it would be very efficient.

and then collect the rain water at weight points, & use it locally if possible.
holy cow! I read …
holy cow! I read about this in popular science! I didn’t know they ACTUALLY made one!
This apparently was …
This apparently was a pilot project built in 1982 and ran nonstop for seven years.
Yes
Yes
According to a New …
According to a New Scientist article, growing crops underneath actually improves efficiency, if you irrigate. The water vapour lost from the leaves is less dense than air, and so strengthens the rising air effect. Plenty of water would be required though.
I wonder how old …
I wonder how old this video is, because the turbines that the Germans are making now are so much better than the old ones. Surely, with the new turbines, the output would be even better. And I wonder if you could irrigate the land underneath to grow food, or whether that would interfere with the generator.
What is the actual …
What is the actual function of the tower? I see that the air has a tendency to rise through the center where the generator is. Is the column of hot air then supposed to pull more air into the system as it rises?
Can we do this …
Can we do this while maintaining a steady enough state to generate electricity from it?

I think its Tedlar, also used as backsheet for solar modules. Insulating & very resistant plastic.
Plus, there would …
Plus, there would be efficiency losses as the air rises, because the fact that the air is rising means that its energy is going elsewhere, and not ultimately towards turning the turbines blades.
Once the heated air …
Once the heated air reaches the tower, it will not have much less force than at the exit of the tower. Yes airspeed will be geater at the top, but the air density will be lower resulting nearly same force. From simplicity aspect, the turbin at the bottom will produce the cheapest electricty per KW.
that is 30KW an …
that is 30KW an hour. Most homes use only 30KW a day. That would be at least 24 homes that can be powered from this tower.
Just a thought. If …
Just a thought. If the upper atmosphere wind speeds are higher than the wind speed in the vertical wind tunnel why not use that to increase power.
Cap the top of the tower with a 90 degree hood that can rotate to match wind direction by use of a stablizer vains and bearings. As upper atmostphere winds are blown by the vent hood, an venturi effect is created increasing the total wind speed of the tower. This will increase the power of turbin below.
it would be much …
it would be much harder engineering wise to put it at the top. It was just a test run.

between 1:15 - 1:20, What is the name of the material again that is use?
I think the Turbine …
I think the Turbine should be placed at the top. My reason is that if the turbine is placed on the bottom you only have the suction of the Chimney pulling air through the blades, But if the TURBINE is placed at the top then all the hot air trying to get out will have to go through the Blades. If you want to see what I am talking about try this with a shop vac. Hold you hand over the tube while you are sucking, and then try to hold you hand over the tube while you are Blowing. Which is harder?
that’s a good …
that’s a good question, I thought the same! I guess that somehow every turbine would slow down the air reducing the energy production of the next turbine… but it sounds pretty lame…
does anyone know the reason?
i wonder what the …
i wonder what the ramifications are of having all that heat energy focused in one place high in the atmosphere will be
If the air …
If the air continues to rise, why not have more turbines in the chimney?

I say build it in death valley.

i’ve seen so many moronic posts that i can’t believe it. some of you need to go back to school. this is a cool idea, but 30kw will power a house, maybe two conservative ones. i seen a post about losing the land to other uses, we have a whole lot of useless desert for this type thing. they should have paved the collection area and probably get 10 times the output… well, its a start.. really cool idea

We can do molecular nuclear fusion from water: No CO2. What are you upset about?

this one in spain is about 200 m,
the tower in aussieland is planned
