Solar Powered Tetroon Generates Enough Lift to Fly

in environment on (#2WSF)
Quelab has created a balloon shaped as a tetrahedron with transparent top and black bottom which lifts with just solar power. They begun this project "to enable us to know that flight is possible without using either the scarce and non-renewable gas Helium, the possibly-dangerous Hydrogen, or even the fossil-fuel Propane".

As a funny side-note: The Tetroon escaped and got reported as UFO.

This is what I call real innovation! I am almost tempted to build one myself. It is very easy to attach some plastics to each by ironing them together.

Did I see correctly that it has two black and two semi-transparent sides?

Nothing new... I had mine already 1982 :-) (Score: 1)
