Dear Physics People, I am a religion teacher with a background in philosophy and theology. I haven't taken a physics or calculus in some years, so there is a lot of information that I'm missing in my head. So here's the deal. Airlines spend millions of dollars on fuel a day (around $32 million). The airlines also spends millions to save very little on fuel each year. Winglets save about 3-5% and cost millions, switching from 30 pound flight kits to 3 pound iPads, and Delta even bought an oil refinery in order to save some money on the East Coast. Airlines will do a lot to save some money. So here is where I need some help, well a lot of help, if the inside of a jet engine is around 3000° F and water breaks down around the same temp. Can I put water in the engine and have it break apart and use that to power the engine. Now I understand that I might have to cool the hydrogen but there is a lot of cool air around the engine so I could do that. I know that hydrogen is very volatile so I want to break it down and then burn it right away. That way I'm not storing hydrogen in the plane. Now I don't need the hydrogen to run the airplane the whole time just maybe 5-10% of the fuel. There is a lot of math that I am missing, and I don't understand much of the math. So I need a lot of help figuring this out. Thanks so much for the teaching me.
