--- Michael, Hey, we kibitzers were merely waiting for you to "focus some light" on the subject, so to speak ... BTW- have you had a comparative look at what would be the optimum level of 'shrinkage' for the solar cell itself when under Fresnel concentration ? ... let me see if I can ask that question more clearly. OK- you can probably make the lens any given size fairly easily, but if you were to find that for a given ratio- let's say that a 100:1 concentration works well for a certain type of solar cell, would you be better off having the cell itself cut small- say 1 cm^2, or even 1 mm^2, or even smaller? The reason for asking is that a tracking mechanism would no doubt be more efficient with a multitude of smaller units, as opposed to fewer larger ones. This would also facilitate putting a flatter array onto a home roof, without the unsightly arms of a larger mechanism. Jones
