@carmichaelmoritz8662 That is the dumbest thing I've heard. One all countries like China and US would have to be on it. Whomever unlocks a new battery technology that is superior has a leg up. Secondly any company to release such a break through would become filthy rich. We are talking about top 5 riches companies.

Yeah let us not be dumping that crap in the atmosphere haha. For a second I was like how is this different then regular fuel - I wasn't thinking. You are correct flights are calculated by the amount of fuel and then average the fuel spent during travel. It is always a catch .22 in terms of design - people are like why don't they just carry more fuel! Well because you weigh more at take off so you're using fuel to carry fuel. Hence drop tanks versus conformal tanks in fighters. Both have their benefits and why aerial refueling is such a game changer for the military. Edit ( Or why rockets use stages even if they could have an efficient magical rocket throughout the flight envelope.)
