skunk, Im sure your not the only one wondering about the current business model with sansIIA vs sansIII. It would be irresponsible for them to not consider a market for each. weight would be the big thing, area coverage and airborne duration would be a big portion of its capability, profitability, airborne durability, etc.
there is a company in Canada that has a patent on a liquid photovoltaic cell that can be sprayed on any surface. I wonder if Bob or anyone at Sanswire knows about this product. big deal there would be weight vs watt output.
