Perfect Example Of Solar Zealots' Hype

In Gizmag,

It's hard to envisage that sort of system working effectively until you tweak the temperature variables and scale the whole thing up. Put this tower in a hot desert area, where the daytime surface temperature sits at around 40 degrees Celsius (104 F), and add in the greenhouse effect and you've got a temperature under your collector somewhere around 80-90 degrees (176-194 F).

Ahh, so THAT's why solar towers aren't built anywhere. Kind of a big disadvantage. And puts the scorcher on those stupid plans to have green greenhouses underneath. For free! Yeah right. Well, I always hated that stupid Desertec crap.

The amazing thing is that this paragraph above is exactly 1 paragraph and 1 photo distant from the following marketroid hype:

Because you want large tracts of hot, dry land for best results, you can build it on more or less useless land in the desert;

Far from consumers. Since when has this been an advantage?

It emits absolutely no pollution - the only emission is warm air at the top of the tower. In fact, because you're creating a greenhouse underneath, it actually turns out to be remarkably good for growing vegetation under there.

Yes that's right, they say that 80-90 degrees celsius is "remarkably good for growing vegetation under there". That's the Worshipers of the Sun God Ra for you, incapable of common sense or of comprehending 'logical contradiction'.

Oh that's right, apparently I made a mistake in assuming these would be EARTH vegetables underneath those solar towers. No, all along it was supposed to be Vulcan vegetables. I feel so stupid now.
