You are not reassured when the lead paragraph 'What is the science behind the AeroCam?' contains zilch 'science' in even a vaguely accepted meaning of the word. The next and last paragraph is even more worryingly headed 'The AeroCam is intelligent science'. Well blow me down. There I was expecting unintelligent science.
The AeroCam looks like an old fashioned agricultural thresher or perhaps a treadmill. You apparently locate a row of them on the eaves of your building where they benefit from the updraft. The blades they, maybe somebody out there can tell us what the science really is.
