Then you come along and snip (only you know why) and misattribute who said what. The part I wrote was "It won't be in Earth orbit then", so your target should have been Mook, not Androcles. The safe thing to do is not snip. Snipping requires effort on your part and saving Google even a kilobyte of storage space is a raindrop in the ocean. This is not 1979 when 16 Kbytes of RAM and a 50 Megabyte hard drive was state-of-the-art, 30 years have past since then and terabytes are cheaper than dirt.

Frankly all this seems academic, I haven't seen anything posted that shows a practical way to convert a laser beam to electricity, unlike a microwave beam. ? Dave |
