Has hydrogen ever been used as a fuel for Buoyancy Assisted Aircraft (BAA)?”?
Seems like the Egg of Columbus” to me, but I’ve been told I have an uncanny grasp of the obvious. Given the huge volume of the pressure envelope and abundance and dependability of sunlight above the clouds, Hydrogen could be produced on board by photo-voltaic cells. Could this BAA actually land with MORE FUEL than […]

Has anyone combined two different solar panels into one?
I have seen two types of solar panels made. Photo voltaic and water heating. Has anyone combined the two? Silicon cells are not 100% efficient, so why not capture the leftover heat as well?
