They are running into manufacturing and assembly issues. Currently the cost is higher then seperate PV and solar hot water. Combining the technologies is actually a very good thing as the water cools the PV panels and raises their efficiency. A typical PV during the prime part of the day can get as hots a 140-160 degrees. Backed with water tubes, it cools to 100-120 and efficiency goes up by 10-15% “i think it would be awesome if you could combine solar photovoltic energy and solar heat pipe energy”

It is only 1% more then the Israelian Uniniversity in Tel Aviv. Satalites solar panals aquire 50%. Well there is a price to that. What is your price per watt. How much of the recources are used. And can you produce tera watts before 2040? Then we talk again. This is nice. It is only 1% more then the Israelian Uniniversity in Tel Aviv. Satalites solar panals aquire 50%.

Why is it that Australian scientists continue to work with just Gallium, Indium, and the mixes of several other conductive elements? Why not concentrate on light absorption via nitrites/ or various nitrogen components?? When nitrogen is added to the mix, it creates significantly more current, but is not well conducted to the edges,and because the compound absorbs nearly all the light spectrum? In Spring, 2008, scientists at U. Berkeley, CA USA discovered this surprising result. Their difficulty was to get the resulting crystals to lie down so it could be manufactured! So 25% is a sad joke when near 98% efficiency of light spectrum absorption is possible. Who determined that the maximum absorption rate was 29%? When did this become your benchmark? Think out of the box. gentlemen! You have much better opportunity when you see the benefits of reducing costs per chip, than increasing the efficiency of a compound that is inferior to other combinations. You might even try to get compounding in space on the space-lab to develop improved structural advantage of your compounding so that industry could advance a few decades! You must understand that gravity has an impact on crystal formation and atomic compound structuring...I recommend you test those proposed items!

It is pretty amazing, but when there's a will, there's a way. There are still many things to know about our world and universe, but until we invest the mindpower, we won't know what we don't know. It's exciting to watch these new discoveries every day though. If you have any friends who doubt the capacity of alternative technologies to solve our energy problems, please direct them to this site. I agree with Tim about discovering new aspects of sunlight.
