Rather than a panel of 1000 expensive solar cells - this solution is to have a cheap reflective dish focusing the sun on one solar cell.



Seems smart to me.

I don't have speakers hooked up.  How is the power stored?

Here is the site of the Ben-Gurion U. National Solar Energy Center:  http://cmsprod.bgu.ac.il/Eng/Units/bidr/Departments/EnvironmentalResearch/solarcenter

The YouTube link is to a $47 ebook.  And I had to shut down the window to escape it.  I hate tactics like that.

I just followed the youtube link.  It went to the little video about the solar cell.  What happened when you clicked on it?

I don't have sound.  Also, my YouTube.com link is slow, so the picture is stop and go with no sound. Less than ideal....

seems like a great solution to some of the expense associated with solar.  I tend to have trouble with videos too. I don't have the patience for them even when they behave properly and they rarely do.

Wow! Not only are the cells smaller, but THEY ARE CHEAPER! That is a big step forward!
I sincerely hope to see affordable solar cells in my lifetime...what's left of it!

It is unfortunate that more & more information gets posted via videos on the internet. I know sometimes, I just wanna read it...I don't want to watch it.

I guess it's because people can't or are too lazy to take the time & read. I used to get frustrated with videos too because the players offered weren't iMac friendly. I've no problems viewing youtube videos. Youtube has been informational & entertainment for me. Windows media videos get deleted immediately. Don't have a WM player & don't want one. 

When I posted the info about the Stowers, I tried to find text, but it didn't show up fast enough in the search engines to suit me, so I posted the clip.

I think the problems with receiving video information have to do with the speed of the internet connection (delivering the video) and the ability of the computer to process that speed.

  The problems with reflectors is that they can be dangerous. I heard, that when they started to use solar power a while ago, they tried to get south americans using solar for i can't remember what and two houses got burnt down and so they dropped it.
  We have establilished a lot of fire saftey behavior, solar is a new thing how to implant that fear of leaving your reflector without vigilence or always covered if you're not there or always pointing at the sky, if we are to have home solar energy. Some home solar cookers like box ones, seem very safe, others with paraboilc reflectors seem lethal. There is a video on you tube in which they call their parabolic cooker, the death ray or something of the sort, it had a water melon steaming and hissing and squirting steam in half a minute more or less.

  The secmol ladakh site has a reflector reflecting sulight on to a mirror in the wall of the kitchen, the mirror then reflects the sun up on to the bottom of a pot cooking inside the kitchen. Interesting eh. It also has some easy to make greenhouse ideas among other things.
