Compilation of test flights.
Pathfinder Solar Plane preceeded Centurion. Pathfinder turned into Pathfinder+ by removing the original center panel and replacing it with a panel that was about 48 feet in length. Centurion turned into Helios Prototype, which turned into Helios and Helios with a fuel cell. The difference between Centurion and Helios prototype was removing the center panel and adding 2 new center panels. Helios flew with 5 pods and had a full solar array. The fuel cell version was made by removing the center pod and replacing it with the fuel cell pod. That is the one at the end of the video.

@camjua00 same with many materials, glass, metal, silicon, plastic it all takes huge amounts of energy to make, as always we will eventually find a way to make things better.

did you know that there is more energy used to build a solar cel, than what it produces in its usefull life?....i'am not saying this isn't progress

i so desperately want to see a video of the crash!
it got into turbolence, got stuck in a u-shape, then shattered and fell into the ocean. please tell me if you find footage of this on youtube! and thumbs up on the comment if you want to help me with my search for that video ;)

well, i guess then you failed as well. solar panels are dark, often close to black, but dont produce heat, at least far less compared to a normal surface of the same darkness. the difference is what goes into electricity. the perfect solar panel is black. if a panel doesnt produce energy, (unconnected/broken) it will get hot in sunlight, while a working panel stays quite cool. if a working panel would heat up and not stay cooler, where would the energy come from?
