minus-squareNora@lemmy.mllinkfedilinkEnglisharrow-up1·11 months agoThat’s what first came to my mind. Water from air to hydrogen from water. Would need to do r&d tho to see if it’s possible.

minus-squareNora@lemmy.mllinkfedilinkEnglisharrow-up1·11 months agoIs the energy from the sun that could be harvested from a blimp sized footprint enough to convert enough hydrogen to account for the leaks in a blimp and to power propellers to keep it in one spot. I don’t know those numbers.
