It may be the the question we ask ourselves the most. (Behind, of course, “What’s for lunch” and “How’d your exam go?”) The answer: “Ask NASA.” (To them all, obviously.)

Most recently, it’s fallen to the ChemE team to answer this question. Initial assumptions of the chemical reactions out of the way, it’s time to buckle down and do some hardcore engineering.

And when you need to engineer something, who better to turn to than NASA?

Using a little-known software called CEA (made available online as CEARUN), we’ve been iteratively testing hundreds of fuel combinations and engine conditions over the last few days to comb through and find The One.

It’s not every program that can crank out 23,000-some lines of code in under five seconds. That’s just the NASA difference, I guess.

More on if it flies later…
