Solar Tower Vortex Generator

Construct your solar collector such that air is guided into wide collection ports at the extremities, spiralling in to much narrower channels at the centre.

From above, such an arrangement might look a bit like an old-timey lollypop.

This should create a pretty tangible whirlwind in the middle. By stabilising the airflow into a vortex, it should generate more power than it might have done otherwise.

       thank you

       You're welcome.

       The peak output of solar flue 101 was worth about $5 an hour, and probably not more than $20 per day. Hard to do worse, I suppose.

       [ldischler], yes, but I guess that figure is only referring to the power output (still not bad if, excluding the turbine, you consider the complete lack of moving parts) - there's nothing stopping us from using the heightened temperatures and potentially tweakable environment to grow plants that might not otherwise grow in the ambient conditions. Now that's not necessarily going to push the value-per-hour up vastly, but it will push it up some - the point being that the entire site doesn't have to be *just* a power station.   

       I would love to live and work in and around a structure like this - different sections, at different distances from the centre would have distinct 'feels' to them - you might be able to rent out some parts of the complex as holiday homes - reliable weather, warm, with a constant breeze - just add a pool and a nice restaurant, and you've got a resort. How many power stations today can double as luxury holiday resorts?   

       Then there are the vinyards that you could have stretched out in a couple of sectors, every year would be a good vintage, because the temperatures would be higher, and more stable.   

       Or the rich foliage in the jungle areas, where tropical plants are tested for their medicinal properties etc.   

       And all of this at a site in the sorts of locations you see people selling off land at a dollar an acre.
