To specify, by fuel I mean fossil, nuclear, chemical and pressurized air. Want to build and design a satellite for my daughter with a camera in it (goPro) with an antenna to be able to view anytime she likes. Want to do a hexagonal approach with solar cells only for power. Want to power the gopro and a GPS locator so she will always know where it is when she wants to find it. Just trying to figure a way to move it so camera can be moved to different directions without using two different 360 degree cameras.
