Bob, glad to see this but for airships?

Professor Faiman's work is very cool, using an inexpensive concave mirror to concentrate light on the much smaller sized solar cell and producing incredible efficiency ratings in the process.

That said, can't see any immediate practical application of this principle to powering an airship.

Nanosolars work seems right up our alley, but could not find any reference to their current efficiency. They did state that 60% was feasible in the future, but have read the same with other thin film manu's.

If you want to read a specific thin film breakthrough with a super 25% eff. (that beats Nanosolars current offering as stated in the piece), read this:

So much happening, am hoping that we can see all this energy collection translated into a successful stratospheric launch for Sanswire/Tao at some point.......soon.
