but wont this just create another problem, the mass for the 'spent' hydrogen would be 9 times more than original because of Oxygen being much weightier (atomic mass: 16). so your fuel tank would basically get 9 times heavier. that will negate any benefit you get from higher energy density. also it may create storage problems because now you have to provision another tank for water storage.
I think they'll just handwave it and release it periodically.
- Hypx 6y agoMetal-air cells have the same problem. That’s why they were briefly considered for airplanes, and then abandoned once they realized that problem.
- Robotbeat 6y agoReleasing it periodically can be done at a slightly lower altitude and in a liquid phase, both of which should significantly reduce impact.
