solar efficiency doubles up

Now that looks promising. Hope it works. I'm wondering how much it will cost though

I was just thinking the same thing. Tripling the efficiency is great, but if, for instance, it costs three times as much, it won't do much good. I hope it's cheap though.
 
As with any new gizmo these days it probably costs a heap if it launches mainstream.

It uses cesium. IIRC producing pure cesium is much more expensive compared to something more commonly used like aluminum.. We're talking hundreds vs cents per gram.

I wonder if we have some thermodynamic majors here on the board. :hmm:
 
If you are talking about triple heat and light energy which the scientists are trying to experiment for gathering efficiency. There is one thing I am worry about is Cancer. Remember the sun with radioactivity going through the window that is suppose to cover the earth to protect us from radioactive. It look like three times is too much to have us risk getting cancer. I don't know what the big deal the scientists were trying to prove on this experiment. I just don't like it when something might go wrong. So I am worry. :Ohno:
 
No need to really worry, Bebo. They are simply one-upping efficiency and rather than just harvesting ultraviolet energy, they've also implemented to harvest heat generation (radiative or conductive heat).

There is nothing "too new" about this, they just combined both forms of solar harvesting into one unit so that it is efficient. No more different like buying a Prius or hybrid Civic.

we have hundreds of nuclear power plants around us. we're A-OK :cool2:

Here's a flaw to your understanding. As the efficiency goes up - it's not because we increased amount of the sun ray energy toward Earth. We are maximizing the efficiency rate from same amount of sunlight we received from Sun.

For example -

in old time - size of 1 football field of solar panels is needed to power 5 houses
5 years later - size of 1 football field is needed to power 15 houses
5 years later - size of 1 football field is needed to power 25 houses

so on...
 
This brings up the point of why I hate JFK and NASA so much.
Just think.....if 40+ years ago JFK had not started a space war but had instead use all the money for research and development of solar energy...each and every building (homes included) would today have cheap solar power...all that money to NASA went to waste.
 
That's good news...hope it's reliable and worth the money for consumers.
