solar heat to electric

[nickle989]

On an overcast - cloudy day in -15 c the solar tube reaches and maintains 38 to 42 c throughout the day.  The tubes are very efficient in collecting the sun's energy of both visable and non-visable light and consentrating it on the inner surfaces.  With light being diffused by the atmosphere does not affect the collector that greatly to make it unusable in the practicle sense. 

$3000.00 per kw is very high for solar thermal ... those folks should go back and do some first grade math.  Each panel of mine has a cost of 750.00 with mods and produces well over 800 watts consistantly on a cloudy day.  Sunny day's are up around 1200 watts.  Storing that energy in a thermal tank to run through the night will be done by a 1200 gallon water tank in ground and insualted. 

The sun in free energy and so is the wind ... just harvest it.

well you doing just open vaccum tubes right? They will make use of the diffused light, concentraitors can't make much use of the diffused light though. But the diffused light energy is probably much less then the direct light energy, what I want to find out is by how much.
