A working model of a Solar Updraft tower, fully functional and producing power ran in Manzanares Spain for most of 9 years. The last stages of Research and Development were focused on crop design under the Solar Green House which I also refer to as the Solar Canopy, because it can also cover things like crops, or PV and Solar Film arrays.
Enviromission has a very nice video. Remember, there was a working design that ran for 9 years.
Of concern for this technology with respect to its feasability, IMHO, the installation of a power plant using Solar Updraft Tower power production technology must include another significant installation of Alternative Energy production that exhibits strong synergy within the economy of scale demanded by Alternative Energy rollout. Here is a link which demonstrates the combination of the Algae biosphere production technology for high grade fuel oil produced in a pond underneath a Solar Updraft Tower canopy, or greenhouse, (skirt).
I will try to update some links above, (in the discussion header), which point to dual and multiple Alternative Energy infrastructure synergies that utilize the land requirements of Solar Updraft Tower most efficiently. The Kathy's like it, :)
Imagine a solar updraft tower where the wall of the tower is a stack of toroidal balloons filled with a buoyant gas such as He or NH3. The tower actually erects itself by floats into the sky! This is…Continue
Thanks for citing my proforma for a solar updraft tower algae biosphere. We can expect some serious technical milestones to be crossed before reaching this revolutionary reduction of the human…Continue
If I am interpreting this paper right, the importance to electrical generation of a water vapor condenser downdraft, as proposed in the solar updraft tower algae biosphere, is more than I thought.…Continue
