Well enough to post here. I never thought when I'll enter all the information of this kind but your post really helps is to share something me.Awesome here.I like your post. I am now waiting for your next post.So keep writing .


With potential fields of solar collectors,what happens to the ground beneath them? Does a different ecology develop? Or are we talking about giant fields of concrete?

John - thanks for the very good question (that I'm not really equipped to answer). First of all, one would hope that the "footprint" of such installations would be minimised - in many ways, desert sand should provide a sufficiently stable platform that concrete foundations can be kept to a minimum. But how they would mitigate against the effects of blowing and drifting sand is not clear, at least in the articles.

Then there's the shade that the installations would provide for desert life, and the part of the plan that appears to envisage re-vegetation as a component project.

Ironically, a recent piece in the New Scientist describes how the days of traditional silicon-based solar cells may be numbered, with the potential for their being replaced by nanoscale light-sensitive antennas that harvest infra-red radiation (see http://www.newscientist.com/article/mg20827915.000-is-night-falling-on-classic-solar-panels.html).

Potentially exciting tech if the costs can be scaled. It still looks to be doing most of its generation during daytime, so I assume its still viable for the Sahara project?

Hmm, and... In your book don't you talk about how the dunes migrate? If there are fields of collectors surely they're at risk of being buried?

Yes, the new technology would certainly work well in the desert, but whether these "semiconductor diodes" use silicon or some other semiconductor - and therefore whether the silicon processing part of the project is still applicable - I'm not sure.

As for dunes, yes they would be a threat, but they do tend to congregate into extensive but confined areas (the self-accumulating nature of sand) and much of the desert is not covered in sand - which is, I assume, where the facilities would be best located.

Exactly! Pretty good article. Very informative. Wow I'm so excited with that innovation!

You really make it seem so easy with your presentation but I find this topic to be really something which I think I would never understand. It seems too complicated and very broad for me. I am looking forward for your next post, I will try to get the hang of it!

This is a great project and I hope they're successful in implementing it. I feel as if the more solar power we're able to harness the better.

B Green Solar Power is dedicated to providing affordable alternatives which help eliminate our country's dependence on foreign supplied oil, contribute to a cleaner healthier environment and alleviate the effects of rising energy costs.

Solar power is definitely the way to go, and in the Sahara it just perpetuates itself.

One thing to remember is that Thomas Edison did numerous experiments before he got the right filament for the electric light bulb. so lets keep trying to find what we need to get a super conductor to bring solar power from the desert to the cities.

Thanks for sharing the useful information. It was really amazing and very informative. Keep sharing more article.
