I have an experimental solar tetroon aloft at this very moment - interested
parties can check its current location using this URL:
This tetroon is 20 feet on a side and made from 13 micron, translucent,
high-density polyethylene. Solar absorption was augmented by the addition
of... powdered tempura paint (added shake-and-bake style)!
Free lift is about what I expected - but the payload was overweight by about
six ounces. So, it's a low, slow, lazy flight today (at least I won't have
to drive far to retrieve it!). Now if the GPS tracker will just keep
working this time....
I'll put some pictures up later today.
